Common Problems

What is going on: Endurance deficit in deep trunk stabilizers and glutes; stiff hips shifting load to the lumbar spine; hours in sustained flexion

Strength work: Back: Spinal Erectors; Core: Transverse Abdominis; Abs: Obliques; Glutes: Max; Glutes: Med; Back: QL; anti-rotation and anti-extension holds; bird dog; side plank; dead bug; glute bridge; hip hinge

Stretching: Hips: Flexors; Legs: Hamstrings; Glutes; Glutes: Piriformis; Spine; Back: Lower Back

Massage: Back: QL; Glutes; Hips: Psoas; Back: Upper Back; Legs: Hamstrings

Also worth doing: Daily walking; break up sitting every 30 min; load-management education

Get it checked if: Bowel or bladder change; saddle numbness; progressive leg weakness; fever; unexplained weight loss; night pain; major trauma; cancer history - urgent referral

What the evidence says: Exercise therapy is first-line in every major guideline. No single exercise type wins; adherence is the active ingredient. Massage: short-term pain relief only.

Prevalence basis: GBD 2021: #1 cause of years-lived-with-disability worldwide; 57% of all primary-care musculoskeletal visits

What is going on: Protective muscle guarding after a trivial movement - bending to pick something up, sneezing, getting out of a car. The spasm is the nervous system splinting the area, not damage to it

Strength work: Once the acute guarding settles: Core: Transverse Abdominis; Glutes: Max; Back: Spinal Erectors; Back: Lower Back

Stretching: AVOID aggressive stretching into the spasm; gentle Spine and Back: Lower Back in small ranges, little and often

Massage: Back: Quadratus Lumborum (QL); Glutes; Back: Upper Back - light, this is where massage earns its place, reducing guarding so movement can restart

Also worth doing: Heat; keep moving in small comfortable ranges; bed rest makes it worse and lengthens the episode

Get it checked if: Bowel or bladder change, saddle numbness, leg weakness, fever, or spasm after significant trauma - urgent

What the evidence says: Movement within comfort plus reassurance resolves most episodes in days. Massage genuinely helps here by reducing guarding. This is a different routine from back-pain prevention and should not be the same one.

Prevalence basis: Primary-care presentation patterns

What is going on: Sustained forward-head posture with weak deep cervical flexors while upper trapezius and levator scapulae work as static holders

Strength work: Neck; Neck: Splenius; Neck: SCM; Back: Traps: Lower; Back: Traps: Middle; Back: Rhomboids; Shoulders: Deltoids: Posterior; chin tucks; Neck: Deep Neck Flexors

Stretching: Neck; Shoulders; Chest; Back: Mid-Back; Neck: Suboccipitals stretch

Massage: Neck & Shoulders; Neck: SCM; Back: Upper Back; Neck: Suboccipitals massage

Also worth doing: Monitor at eye height; phone at eye level; hourly movement break

Get it checked if: Arm weakness or numbness; unsteady walking; severe headache with neck stiffness and fever; pain after trauma

What the evidence says: Specific neck and shoulder-girdle strength training has strong RCT support (Ylinen; Andersen office-worker trials). Stretching alone underperforms strengthening.

Prevalence basis: GBD 2021 ranks neck pain 2nd among musculoskeletal conditions; 11-41% of primary-care musculoskeletal visits

What is going on: Short and stiff pecs, lats and upper traps paired with weak lower traps, rhomboids, rear delts, serratus and deep neck flexors

Strength work: Back: Traps: Lower; Back: Traps: Middle; Back: Rhomboids; Shoulders: Deltoids: Posterior; Shoulders: Serratus Anterior; face pulls; band pull-aparts; wall slides; Neck: Deep Neck Flexors

Stretching: Chest; Back: Lats; Hips: Flexors; Neck

Massage: Back: Upper Back; Chest; Neck & Shoulders

Also worth doing: Workstation setup; 30-30 sit-stand alternation

Get it checked if: Numbness down the arm; dizziness on neck rotation

What the evidence says: Posture change on its own is a weak predictor of pain relief. The strengthening carries the benefit; sell it as strength not as posture.

Prevalence basis: Not a diagnosis so not formally counted; it is the mechanical driver behind neck pain, tension headache, shoulder pain and cervicogenic headache

What is going on: Facet joint stiffness and shortened anterior neck and chest tissue, plus years of a forward-head posture that has the neck already living in extension at the top and flexion at the bottom

Strength work: Neck; Neck: Deep Neck Flexors; Back: Traps: Lower - the deep flexors have to be strong before extension range is safe to add

Stretching: Neck; Neck: SCM stretch via gentle extension; Chest; Spine - thoracic extension gives back much of the apparent neck range

Massage: Neck & Shoulders; Neck: SCM; Neck: Suboccipitals massage

Also worth doing: Restore thoracic extension first - it is safer and it does most of the work; avoid sustained end-range extension

Get it checked if: Dizziness, visual change, nausea or arm symptoms on looking up - stop and get assessed; sustained end-range extension is the position most associated with vertebral artery events

What the evidence says: Gain the range from the thoracic spine before pushing the neck. This is the one direction of neck movement where forcing end range carries real risk, so the routine should say so.

Prevalence basis: Cervical range-of-motion norms

What is going on: Rhomboids, mid-traps and levator scapulae working as static holders for hours against a slumped thoracic spine and protracted shoulder blades. The muscle that aches is the one being over-lengthened and held, not the tight one

Strength work: Back: Rhomboids; Back: Traps: Middle and Lower; Shoulders: Deltoids: Posterior; Shoulders: Serratus Anterior; rows and scapular retraction

Stretching: Chest; Back: Lats; Spine - thoracic extension; Neck

Massage: Back: Upper Back; Neck & Shoulders; Massage Ball against a wall

Also worth doing: Screen and chair setup; hourly movement break; the ache follows sustained position more than it follows any single muscle

Get it checked if: Interscapular pain with breathlessness, sweating or chest pressure can be cardiac - take it seriously; night pain or weight loss needs review

What the evidence says: Strengthening the scapular retractors plus changing the sustained position works. Stretching the aching muscle feels good briefly and does nothing - it is already long.

Prevalence basis: Occupational health surveys

What is going on: Sarcomere shortening plus connective-tissue stiffening from disuse; sitting holds hips and thoracic spine at end range for hours

Strength work: Full Body; loaded stretching through full ROM beats passive stretching for lasting gains

Stretching: Full Body; Total Body Stretch Routine long and quick; Spine; Trunk; Hips; Legs: Hamstrings

Massage: Foam Roller Massage; Massage Stick; Massage Gun

Also worth doing: Move every joint through full range daily; heat before stretching

Get it checked if: None for stretching itself; sudden loss of ROM with pain and swelling suggests joint pathology

What the evidence says: Static stretching improves ROM reliably. It does not prevent injury or reduce soreness - do not claim that.

Prevalence basis: Cross-sectional ROM norms; not a disease so not tracked in prevalence registries

What is going on: Not a medical problem - a programming one. Standard beginner routines assume body-weight squats, lunges, planks and jogging, all of which load knees, hips and wrists at multiples of body weight. The exercise hurts, the person concludes exercise is not for them, and stops

Strength work: Seated and supported strength first: Chair Workout; Legs: Quads via seated leg extension and sit-to-stand; Back: Lats via seated rows; Chest: Pecs via incline or machine press; Glutes: Max via bridges; Hands, Fingers, Forearms, Grip. Resistance training is the joint-friendly modality here, not cardio

Stretching: Hips: Flexors; Legs: Hamstrings; Legs: Calves; Full Body - seated or supported versions

Massage: Legs: Calves; Legs: Quads; Feet, Toes, Ankles

Also worth doing: Pool Exercises removes almost all joint load; walking in short frequent bouts rather than one long one; strength before impact, always

Get it checked if: Chest pain, unusual breathlessness or dizziness on exertion needs assessment first; check foot sensation before any impact work in anyone with diabetes

What the evidence says: The evidence point that matters: resistance training is better tolerated than jogging at higher body weights, preserves lean mass, and improves metabolic health independent of weight loss. Starting seated is not a lesser version - it is the correct progression.

Prevalence basis: Exercise adherence literature

What is going on: Facet stiffness plus shortened rotators and habitual mid-range-only movement. The joint keeps the range it is regularly asked for and quietly gives up the rest

Strength work: Neck; Neck: Splenius; Neck: SCM; Neck: Deep Neck Flexors; rotation holds at end range

Stretching: Neck; Neck: Suboccipitals stretch; Back: Mid-Back - thoracic rotation contributes a third of the total

Massage: Neck & Shoulders; Neck: SCM; Neck: Suboccipitals massage

Also worth doing: Practice the actual task - look over each shoulder several times a day; mirrors do not replace the movement

Get it checked if: Dizziness, visual disturbance or nausea on neck rotation needs assessment before any rotation program

What the evidence says: Very trainable and very functional. Rotation range responds to daily end-range work within weeks, and this is one of the clearest cases where a stretch routine changes something people care about.

Prevalence basis: Cervical range-of-motion norms and driving-cessation studies

What is going on: The thoracic spine is built to rotate and is held still for hours. The ranges it loses get taken from the neck and lumbar spine instead, which is why this shows up as neck or low back pain

Strength work: Back: Spinal Erectors; Abs: Obliques; Back: Traps: Middle and Lower; loaded rotation and anti-rotation

Stretching: Back: Mid-Back; Spine; Trunk; Chest; Back: Lats; open-book and thread-the-needle positions

Massage: Back: Upper Back; Foam Roller Massage; Massage Ball

Also worth doing: Rotate deliberately every hour; a chair with no back forces more of it

Get it checked if: Sharp mid-back pain with breathlessness, or a new fixed curvature, needs assessment

What the evidence says: Restoring thoracic rotation reduces the load taken by the neck and shoulder above and the lumbar spine below. It is upstream of several other entries in this list, which makes it unusually high-value per minute spent.

Prevalence basis: Spinal range-of-motion studies

What is going on: Usually NOT a short muscle. Three commoner causes: an anteriorly tilted pelvis holding the hamstrings at length already, neural tension referring from the lumbar spine or sciatic nerve, and protective tone around a weak or overworked muscle. Stretching a long muscle harder is why it never resolves

Strength work: Legs: Hamstrings - loaded work through full range, Romanian deadlifts and Nordics, builds length better than stretching; Glutes: Max; Core: Transverse Abdominis to correct the pelvic tilt

Stretching: Legs: Hamstrings - useful, but not on its own; Hips: Flexors is often the more productive stretch

Massage: Legs: Hamstrings; Glutes; Back: Quadratus Lumborum (QL)

Also worth doing: Test which it is: if the tightness eases when you posteriorly tilt the pelvis, it is position not length; if it changes with ankle dorsiflexion or neck flexion, it is neural

Get it checked if: Tightness with numbness, tingling or pain below the knee is neural - stop stretching it and see the sciatica entry

What the evidence says: Eccentric loading through range increases hamstring length as well as or better than static stretching, and it lasts. This entry exists mainly to stop the app prescribing more of what has not worked.

Prevalence basis: Clinical observation; not a registry diagnosis

What is going on: Sustained low-level contraction and trigger points in upper trapezius, suboccipitals, SCM and temporalis; sensitized pericranial muscles

Strength work: Neck; Back: Traps: Lower; Back: Rhomboids; shoulder-girdle endurance work; Neck: Deep Neck Flexors

Stretching: Neck; Shoulders; Chest; Neck: Suboccipitals stretch

Massage: Neck & Shoulders; Neck: SCM; Jaw & Face TMJ; Back: Upper Back; Neck: Suboccipitals massage

Also worth doing: Hydration; screen breaks; sleep regularity

Get it checked if: Thunderclap onset; first severe headache after 50; fever with stiff neck; neurological deficit; worse when lying flat; wakes from sleep

What the evidence says: Shoulder-girdle strength training reduced headache in office-worker RCTs. Massage of pericranial muscles has moderate short-term evidence.

Prevalence basis: Meta-analysis of population-based data from 41,614 adults across 17 countries

What is going on: Chronic energy surplus; muscle loss during dieting worsens the metabolic outcome and drives regain

Strength work: Full Body; Gym total body; compound multi-joint lifts 2-4x/week to defend lean mass in a deficit

Stretching: Any - not a driver here

Massage: Not a driver here

Also worth doing: Daily step target; protein intake; NEAT

Get it checked if: Rapid unintentional weight loss; exertional chest pain or breathlessness

What the evidence says: Exercise alone produces small weight loss but is the single best predictor of maintained loss and preserves lean mass. Frame it that way, not as a fat-burner.

Prevalence basis: NHANES; near-identical figures in most high-income countries

What is going on: Elevated peripheral resistance and reduced arterial compliance

Strength work: Isometric wall squat and isometric handgrip - 4 x 2 min holds at roughly 30% of max effort, 3x/week; plus dynamic full-body resistance work

Stretching: Any - secondary here

Massage: Whole-body relaxation massage lowers blood pressure transiently only

Also worth doing: Aerobic work; sodium reduction; sleep

Get it checked if: Uncontrolled BP above 180/110 needs clearance first; never hold the breath (Valsalva) against load

What the evidence says: Network meta-analysis of 270 RCTs and 15,827 people: isometric training gave the largest fall of any mode at -8.24/-4.00 mmHg, with the wall squat ranked best. Dynamic resistance -4.55/-3.04.

Prevalence basis: NHANES under 2017 ACC/AHA criteria

What is going on: Handedness plus habit plus, most often, an old injury that was never fully rehabilitated. The stronger side quietly takes over every two-legged and two-armed movement, so barbell and machine work can hide a large deficit indefinitely

Strength work: UNILATERAL loading is the whole intervention: single-leg squats and step-downs, split squats, single-arm rows and presses, suitcase carries loaded on the WEAKER side. Glutes: Med; Legs: Quads; Back: Lats; Core: Transverse Abdominis; Abs: Obliques

Stretching: Stretch the tighter side more, but expect less from it than from the strength work; Hips: Flexors; Back: Lats; Back: Quadratus Lumborum (QL) area

Massage: Back: Quadratus Lumborum (QL); Glutes; Back: Upper Back - the habitually shortened side

Also worth doing: Start every set with the weaker side and match the stronger side to it; a mirror or video tells you more than how it feels

Get it checked if: A sudden or progressive one-sided weakness is neurological until proven otherwise - that is not an imbalance, get it assessed

What the evidence says: Unilateral work is the only thing that reliably closes a side difference; bilateral training preserves it. Small asymmetries are normal and need no treatment - do not manufacture a problem.

Prevalence basis: Bilateral strength testing literature

What is going on: Microdamage and inflammatory response 24-72 h after unaccustomed eccentric load

Strength work: Gradual load progression is the real prevention

Stretching: Full Body; light dynamic movement beats static stretching here

Massage: Foam Roller Massage; Massage Gun; Massage Stick; Legs: Quads; Legs: Hamstrings; Legs: Calves

Also worth doing: Light active recovery; sleep

Get it checked if: Severe pain with dark urine after extreme exertion = possible rhabdomyolysis, urgent

What the evidence says: Post-exercise massage is the best-supported use of massage in the whole literature (moderate effect on soreness). Static stretching does NOT prevent or reduce DOMS - do not claim it.

Prevalence basis: Not tracked as a condition; it is the most common reason people abandon a new program

What is going on: Skeletal muscle is the main glucose sink; low muscle mass and inactivity reduce insulin-stimulated uptake

Strength work: Full Body; Legs: Quads; Glutes; Legs: Calves: Soleus - soleus work and post-meal walking blunt glucose spikes; resistance training 2-3x/week

Stretching: Secondary

Massage: Secondary

Also worth doing: 10-15 min walk after meals

Get it checked if: Hypoglycemia risk if on insulin or sulfonylureas; check feet for numbness before impact work

What the evidence says: Resistance training lowers HbA1c by roughly 0.5-0.7 percentage points; combined resistance plus aerobic beats either alone.

Prevalence basis: CDC National Diabetes Statistics Report

What is going on: Elevated evening arousal and sympathetic tone; also pain-driven waking

Strength work: Daytime resistance training improves sleep quality (do not train hard within 2 h of bed)

Stretching: Legs: Hamstrings; Hips: Flexors; Spine; Full Body - slow evening sequence

Massage: Foam Roller Massage; Neck & Shoulders; Feet, Toes, Ankles

Also worth doing: Consistent wake time; light exposure; wind-down

Get it checked if: Loud snoring with witnessed pauses points at sleep apnea - see the Snoring and obstructive sleep apnea entry

What the evidence says: Exercise improves sleep quality with a small-to-moderate effect. Massage improves sleep in several populations. Evening stretching is well tolerated and low-risk.

Prevalence basis: Population sleep surveys across high-income countries

What is going on: Sustained sympathetic activation with muscular bracing, shallow chest breathing and reduced parasympathetic tone

Strength work: Full Body; resistance training reduces anxiety symptoms with a moderate effect regardless of strength gained

Stretching: Neck; Chest; Spine; Hips: Flexors

Massage: Neck & Shoulders; Back: Upper Back; Professional Massage; Hands, Fingers

Also worth doing: Slow nasal breathing with a long exhale; outdoor walking

Get it checked if: Panic with chest pain and breathlessness must have cardiac causes excluded first

What the evidence says: Resistance training reduces anxiety symptoms in meta-analysis. Massage reliably lowers state anxiety immediately after treatment; durable effect is less certain.

Prevalence basis: National Comorbidity Survey replication and NIMH estimates

What is going on: Loss of type II fibers and motor units; anabolic resistance means older muscle needs more stimulus and more protein

Strength work: Full Body; Legs: Quads; Glutes: Max; Back: Lats; Chest: Pecs; progressive overload is non-negotiable; sit-to-stand as an entry movement

Stretching: Secondary

Massage: Secondary

Also worth doing: Protein 1.2-1.6 g/kg/day; vitamin D

Get it checked if: New weakness on one side or with numbness is neurological, not sarcopenia

What the evidence says: Progressive resistance training is the only intervention proven to reverse sarcopenia. Nothing else comes close.

Prevalence basis: EWGSOP2 criteria applied to population cohorts

What is going on: Pain that has outlasted tissue healing. The nervous system has become better at producing pain, so hurt no longer equals harm - and rest, avoidance and fear make it worse rather than better

Strength work: Full Body - graded exposure, starting well below the flare threshold and progressing on a schedule rather than on how it feels that day

Stretching: Full Body; region-specific gentle work; movement variety matters more than range gained

Massage: Professional Massage; Foam Roller Massage - useful for temporary relief that makes movement possible

Also worth doing: Pain education (understanding that hurt does not equal harm changes outcomes); pacing; sleep; graded return to valued activity

Get it checked if: New pain that is different in character from the usual pain still needs assessment - having chronic pain does not protect you from having something else

What the evidence says: Exercise of almost any type helps chronic pain, and the type matters much less than the graded, consistent delivery. Pain education plus exercise beats exercise alone. Fear of movement predicts disability better than any imaging finding.

Prevalence basis: CDC National Health Interview Survey

What is going on: Combined loss of leg strength, hip and ankle range, and the balance and confidence to move through the transition

Strength work: Legs: Quads; Glutes: Max; Core: Transverse Abdominis; Hips: Adductors; sit-to-stand and half-kneeling-to-stand progressions

Stretching: Hips: Flexors; Legs: Calves - ankle dorsiflexion limits the whole movement; Hips: Adductors

Massage: Legs: Quads; Glutes

Also worth doing: Practice the actual transition, both directions, several times a week - it is a skill as much as a capacity

Get it checked if: Anyone who has already had a fall and cannot get up needs a plan (phone within reach, a rehearsed rolling method) as well as training

What the evidence says: The sitting-rising test predicts all-cause mortality independently of age and sex. It is trainable, and it is the single most functionally meaningful thing on this list for anyone over 60.

Prevalence basis: Sitting-rising test cohort studies

What is going on: Quadriceps and hip-abductor weakness increases joint loading rate; stiff calves and hip flexors change gait mechanics

Strength work: Legs: Quads; Legs: Quads: Rectus Femoris; Glutes: Med; Glutes: Max; Legs: Hamstrings; Legs: Calves; terminal knee extension; step-downs; single-leg work

Stretching: Legs: Quads; Legs: Hamstrings; Legs: Calves; Hips: IT Band; Hips: Flexors

Massage: Legs: Quads; Hips: IT Band; Legs: Calves; Legs: Hamstrings

Also worth doing: Load management; body weight; cycling as a low-impact base

Get it checked if: Locked knee; giving way; hot swollen joint with fever; inability to bear weight after trauma

What the evidence says: Exercise therapy is first-line for knee OA in OARSI, ACR and NICE guidance, with pain relief comparable to NSAIDs and no drug risk.

Prevalence basis: GBD 2021 and POLAR primary-care database

What is going on: Rotator cuff and scapular stabilizer weakness lets the humeral head migrate; tight posterior capsule and pecs restrict elevation

Strength work: Shoulders: Rotator Cuff; Supraspinatus; Infraspinatus & Teres Minor; Subscapularis; Back: Traps: Lower; Shoulders: Serratus Anterior; external rotation and scaption work

Stretching: Shoulders; Chest; Back: Lats; sleeper stretch for posterior capsule

Massage: Shoulders: Rotator Cuff; Back: Upper Back; Chest

Also worth doing: Avoid sustained overhead work while irritable

Get it checked if: Inability to lift the arm at all after trauma; night pain with fever; visible deformity

What the evidence says: Progressive exercise matched surgical decompression in the CSAW and Finnish FIMPACT trials. Exercise first, always.

Prevalence basis: POLAR primary-care database; rotator cuff tendinopathy annual prevalence 0.5-7.4%

What is going on: Combined capsular tightness, short lats and pecs, and a stiff thoracic spine that cannot extend to let the arm finish the movement. Rarely one tissue

Strength work: Shoulders: Rotator Cuff; Back: Traps: Lower; Shoulders: Serratus Anterior; Shoulders: Deltoids - strength at end range is what holds the new range

Stretching: Shoulders; Chest; Back: Lats; Spine - thoracic extension is the hidden half of overhead reach; sleeper stretch for internal rotation

Massage: Back: Upper Back; Shoulders: Rotator Cuff; Chest

Also worth doing: Reach overhead daily; a doorway or wall slide as a habit rather than a workout

Get it checked if: Sudden loss of range after trauma, or range loss with night pain and fever, needs assessment; progressive stiffness in a diabetic suggests frozen shoulder

What the evidence says: Range gained without strength at that range is not kept. Pair the stretch with end-range loading - and remember a third of overhead reach comes from the thoracic spine, not the shoulder.

Prevalence basis: Functional range studies

What is going on: Six to eight hours of body weight compressing the shoulder in adduction and internal rotation. It is a sustained-load problem, so the daytime program only half-works if the night position does not change

Strength work: Shoulders: Rotator Cuff; Infraspinatus & Teres Minor; Back: Traps: Lower; Shoulders: Deltoids: Posterior

Stretching: Chest; Back: Lats; posterior capsule via the sleeper stretch - gently, this tissue is already compressed

Massage: Back: Upper Back; Shoulders: Rotator Cuff; Chest

Also worth doing: A pillow hugged in front to stop the top shoulder rolling forward, and a pillow thick enough to keep the neck level; alternate sides

Get it checked if: Night pain that wakes you every night regardless of position, with weakness, needs assessment

What the evidence says: The positional fix does more than any exercise here, and it costs nothing. Cuff strengthening keeps it away once the position is sorted.

Prevalence basis: Sleep posture and shoulder clinic data

What is going on: Motor-neuron hyperexcitability with a shortened muscle at rest; plantarflexed sleeping position keeps calves short

Strength work: Legs: Calves: Gastrocnemius and Soleus light strengthening

Stretching: Legs: Calves; Legs: Calves: Gastrocnemius; Legs: Calves: Soleus; Legs: Hamstrings - nightly before bed

Massage: Legs: Calves; Legs: Hamstrings; Feet, Toes, Ankles

Also worth doing: Hydration; loosen bedsheets so the foot is not held pointed

Get it checked if: Cramps with weakness, wasting or twitching that persist need neurological review; new cramps on a statin or diuretic - check with prescriber

What the evidence says: Nightly calf and hamstring stretching cut cramp frequency and severity in a placebo-controlled RCT in over-55s. One of the cleanest wins on this list.

Prevalence basis: Population surveys in older adults

What is going on: Restricted talocrural dorsiflexion from joint capsule stiffness or a short soleus. The knee cannot travel forward, so the body finds range by lifting the heel, rounding the low back or collapsing the arch - which is why this shows up as knee, back or foot pain

Strength work: Legs: Calves: Soleus; Legs: Calves: Gastrocnemius; Legs: Calves: Tibialis Anterior; Feet, Toes, Ankles - loaded calf work through full dorsiflexion

Stretching: Legs: Calves; Legs: Calves: Soleus - knee-bent for soleus, knee-straight for gastrocnemius, and most people only ever do the straight one; Feet, Toes, Ankles

Massage: Legs: Calves; Massage Stick; Feet, Toes, Ankles

Also worth doing: Knee-to-wall test to measure it and to track it; a heel-raised shoe is a workaround, not a fix

Get it checked if: Sudden loss of dorsiflexion with pain and swelling after injury needs fracture assessment

What the evidence says: One of the highest-leverage restrictions in the body: it is upstream of knee pain, plantar heel pain, flat feet and squat mechanics. Knee-bent (soleus) work is the part that matters and the part everyone skips.

Prevalence basis: Ankle range-of-motion screening studies

What is going on: The hips do not move first, so the lumbar spine provides the flexion. Usually a motor pattern problem rather than a strength or flexibility one, which is why it responds to practice faster than to training

Strength work: Glutes: Max; Legs: Hamstrings; Back: Spinal Erectors; Core: Transverse Abdominis; hip hinge patterning unloaded, then loaded; Romanian deadlift

Stretching: Legs: Hamstrings; Hips: Flexors; Legs: Calves - restricted ankles push you into rounding too

Massage: Legs: Hamstrings; Back: Quadratus Lumborum (QL); Glutes

Also worth doing: Practice with a dowel along the spine to feel the difference; hinge for anything below knee height

Get it checked if: Any bending that reproduces leg pain or numbness needs the sciatica entry instead

What the evidence says: A skill, not a fitness quality. Twenty repetitions a day for two weeks changes it, and it is the single most protective movement habit for the low back.

Prevalence basis: Occupational biomechanics literature

What is going on: Weak intrinsic foot muscles and stiff calves overload the plantar structures; narrow toe boxes deform the forefoot

Strength work: Feet, Toes, Ankles; Toe Neuromuscular Exercises; Legs: Calves: Tibialis Anterior; short-foot and toe-spread work; Feet, Toes, Ankles: Intrinsic Foot Muscles

Stretching: Feet, Toes, Ankles; Legs: Calves; Feet, Toes, Ankles: Plantar Fascia stretch

Massage: Feet, Toes, Ankles; Massage Ball; Feet, Toes, Ankles: Plantar Fascia massage

Also worth doing: Wide toe box footwear; Wear Toe Spacers

Get it checked if: Numbness or burning suggests neuropathy; sudden midfoot pain and swelling in a diabetic is an emergency (Charcot)

What the evidence says: Foot intrinsic strengthening improves pain and function in several small RCTs. Massage gives short-term relief.

Prevalence basis: Framingham Foot Study and equivalent cohorts

What is going on: Capsular tightness and short deep external rotators. Lost hip rotation gets borrowed from the lumbar spine and the knee, which is why it turns up as back pain in golfers and knee pain in runners

Strength work: Glutes: Med; Hips: Deep External Rotators; Glutes: Max; controlled rotation work in 90/90

Stretching: Hips; Glutes: Piriformis; Hips: Adductors; Hips: Flexors; 90/90 transitions

Massage: Glutes; Hips; Hips: Tensor Fasciae Latae (TFL)

Also worth doing: Sit on the floor in varied positions rather than always in a chair

Get it checked if: Hip rotation that is painful and hard-stopped rather than stiff may be arthritis or impingement - see those entries

What the evidence says: Cheap to train, and it protects the two joints either side of it. Restricted internal rotation is one of the better predictors of low back pain in rotational sports.

Prevalence basis: Hip range-of-motion screening

What is going on: Hip flexors held short by sitting reciprocally inhibit the glutes; abdominal wall lengthens; the lumbar spine takes the extension load

Strength work: Glutes: Max; Glutes: Med; Glutes: Min; Core: Transverse Abdominis; Legs: Hamstrings; glute bridge; hip thrust; clamshell; monster walk

Stretching: Hips: Flexors; Legs: Quads; Back: Lower Back

Massage: Hips: Psoas; Hips: Iliacus; Hips: TFL; Glutes

Also worth doing: Stand and walk breaks every 30 min

Get it checked if: Groin or hip pain with limp in a child or adolescent needs imaging

What the evidence says: Glute strengthening is well supported for low back and knee pain. The postural label matters less than the strength gained.

Prevalence basis: Mechanically implicated in low back pain, knee pain, hip pain, runner's knee and outer hip pain

What is going on: Hip abductor and extensor weakness with loss of internal rotation; capsular stiffness

Strength work: Glutes: Med; Glutes: Max; Hips: Deep External Rotators; Hips: Abductors; Hips: Adductors

Stretching: Hips; Hips: Flexors; Hips: Adductors; Glutes: Piriformis; Hips: IT Band; 90/90 positions

Massage: Hips; Glutes; Hips: Adductors; Hips: IT Band

Also worth doing: Reduce deep hip flexion if it pinches; walking aids when severe

Get it checked if: Groin pain after a fall in an older adult - assume fracture; night pain with fever; inability to weight-bear

What the evidence says: Exercise therapy is first-line for hip OA and delays joint replacement. Effects are smaller than for the knee but real.

Prevalence basis: Primary-care and cohort estimates

What is going on: Prostaglandin-driven uterine contraction with referred pain into the low back and inner thighs; pelvic and lumbar muscle guarding amplifies it

Strength work: Core: Transverse Abdominis; Glutes: Max; light full-body work during the cycle

Stretching: Hips: Adductors; Hips: Flexors; Back: Lower Back; Spine; child pose and cat-cow

Massage: Back: Lower Back area; Back: QL; abdominal massage

Also worth doing: Heat; regular aerobic exercise across the whole cycle

Get it checked if: New severe pain, heavy bleeding, or pain outside menstruation needs gynecological review (endometriosis)

What the evidence says: Exercise reduces menstrual pain intensity in meta-analysis. Stretching and heat have consistent small benefits. Abdominal massage has positive small trials.

Prevalence basis: WHO and gynecology society estimates; one of the highest-prevalence entries on this list

What is going on: Cyclical hormonal sensitivity affecting mood, fluid balance and pain thresholds; exercise modulates several of the pathways at once

Strength work: Full Body; regular moderate resistance training across the whole cycle rather than only during symptoms

Stretching: Hips: Adductors; Back: Lower Back; Spine; Full Body

Massage: Back: QL; Neck & Shoulders; Professional Massage

Also worth doing: Consistent aerobic exercise; sleep regularity; reducing alcohol in the luteal phase

Get it checked if: Symptoms severe enough to disrupt work or relationships suggest PMDD and deserve medical treatment, not just exercise

What the evidence says: Regular aerobic and resistance exercise reduces PMS symptom severity in RCTs. The benefit comes from training all month, not from exercising during the symptomatic week.

Prevalence basis: Gynecology and psychiatry epidemiology

What is going on: Slow colonic transit plus, in many, paradoxical pelvic floor contraction on straining

Strength work: Core: Transverse Abdominis; Abs; walking is the strongest simple intervention

Stretching: Spine; Trunk; knees-to-chest and twists

Massage: Abdominal (colonic) massage following the colon path

Also worth doing: Fiber and fluids; unhurried toilet time; footstool for squat position

Get it checked if: Blood in stool; unexplained weight loss; new constipation after 50; alternating with diarrhea - refer

What the evidence says: Abdominal massage has moderate RCT support for chronic constipation. Physical activity helps modestly.

Prevalence basis: Systematic review of population studies

What is going on: Gut-brain axis dysregulation with visceral hypersensitivity and altered motility; stress and inactivity both worsen it

Strength work: Core: Transverse Abdominis; Full Body - moderate regular exercise reduces symptom severity

Stretching: Spine; Trunk; Hips: Flexors

Massage: Abdominal massage following the colon path; Back: QL

Also worth doing: Walking after meals; diaphragmatic breathing; sleep; dietary work with a dietitian

Get it checked if: Blood in stool, unexplained weight loss, new symptoms after 50, or nocturnal symptoms are NOT IBS - refer

What the evidence says: Physical activity improves IBS symptom severity in RCTs and predicts long-term improvement. Abdominal massage helps the constipation-predominant type.

Prevalence basis: Gastroenterology population studies

What is going on: Sustained near-focus and reduced blink rate; the neck and upper back component comes from screen height and duration

Strength work: Neck; Back: Traps: Lower; Eye Strengthening Exercises

Stretching: Neck; Shoulders; Chest

Massage: Neck & Shoulders; Jaw & Face; gentle orbital and temple work

Also worth doing: 20-20-20 rule; screen at eye height; blink deliberately

Get it checked if: Sudden vision loss, flashes, floaters or double vision - urgent ophthalmology

What the evidence says: Eye exercises do not fix refractive error. The neck and posture half of this is the part strength and stretching genuinely improve.

Prevalence basis: Occupational health surveys

What is going on: Localized taut bands with sensitized nociceptors, usually where a muscle works as a static postural holder

Strength work: Strengthen the muscle that keeps knotting - it is usually the one being used as a strut, not the one that is weak in isolation

Stretching: Region-specific stretch item for the affected muscle

Massage: Trigger Point Massage; Massage Ball; Massage Gun; Foam Roller Massage; Back: Upper Back; Neck & Shoulders

Also worth doing: Change the sustained posture that keeps loading it

Get it checked if: A painful lump that is growing, hard, fixed or has skin change is not a trigger point - refer

What the evidence says: Massage and pressure release give reliable short-term relief. Lasting change usually requires strengthening or changing the load.

Prevalence basis: Myofascial pain literature; not a registry-tracked diagnosis

What is going on: Gas bubble collapse in joint fluid, tendons flicking over bone, or normal age-related surface roughening. Painless noise has no association with joint damage or future arthritis

Strength work: Whatever the region needs for other reasons; strengthening often reduces the noise by improving control

Stretching: Region-specific stretch item where the tissue is genuinely tight

Massage: Region-specific; not needed for noise alone

Also worth doing: Reassurance is the intervention. Knuckle cracking does not cause arthritis - that has been studied and refuted

Get it checked if: Noise WITH pain, swelling, locking or giving way is a different matter and belongs to whichever specific entry fits

What the evidence says: Painless crepitus needs no treatment. Including this entry stops the recommender from inventing a problem, and answers a question users genuinely ask.

Prevalence basis: Musculoskeletal examination literature

What is going on: Loss of forearm and intrinsic hand muscle; also a proxy for whole-body strength

Strength work: Hands, Fingers, Forearms, Grip; Arms: Forearms: Wrist Flexors; Wrist Extensors; Brachioradialis; farmer carries; dead hangs

Stretching: Hands, Fingers, Wrists

Massage: Hands, Fingers; Arms: Forearms

Also worth doing: Carry your own bags; open jars

Get it checked if: Sudden one-sided grip loss is neurological - urgent

What the evidence says: Grip training improves grip. The mortality association is a marker of overall strength, so pair it with full-body work rather than selling grip alone.

Prevalence basis: Prospective cohort evidence (PURE study and others)

What is going on: Reduced ankle proprioception, slower reactive stepping and weaker hip abductors

Strength work: Glutes: Med; Legs: Calves; Feet, Toes, Ankles; Legs: Quads

Stretching: Feet, Toes, Ankles; Legs: Calves

Massage: Feet, Toes, Ankles

Also worth doing: Tandem stance; single-leg stance progressions; eyes-closed and head-turn variations; Stability Ball/Bosu; Wobble Cushion; Balance Board

Get it checked if: New unsteadiness with numbness, double vision or slurred speech is an emergency

What the evidence says: Balance and functional training cuts fall rate by 24% with high-certainty evidence; adding resistance training takes it to 34%.

Prevalence basis: Functional testing norms

What is going on: Multifactorial: strength loss, slowed reaction, poor ankle proprioception, medication effects, vision, home hazards

Strength work: Legs: Quads; Glutes: Med; Legs: Calves; sit-to-stand; step-ups; Full Body

Stretching: Legs: Calves; Hips: Flexors; Feet, Toes, Ankles

Massage: Feet, Toes, Ankles; Legs: Calves

Also worth doing: Balance training is the essential ingredient - at least 3 h/week total exercise; Tai Chi as an alternative

Get it checked if: Any fall with head strike on anticoagulants is an emergency; recurrent unexplained falls need medical workup

What the evidence says: Cochrane 2019: balance and functional training -24% fall rate (high certainty); multiple exercise types -34%; Tai Chi -19%. Otago program: 23-40% reduction.

Prevalence basis: CDC injury surveillance

What is going on: Bone loses mineral without mechanical strain; estrogen loss accelerates it after menopause

Strength work: Heavy compound lifting - deadlift, squat, overhead press at high intensity plus impact work; Legs: Quads; Back: Spinal Erectors; Glutes; Full Body

Stretching: Avoid loaded end-range spinal flexion

Massage: General relaxation only

Also worth doing: Impact - jumping or heel drops; balance work to prevent the fall that causes the fracture

Get it checked if: Known vertebral fracture, very low T-score or recent fracture needs supervised programming; avoid loaded spinal flexion and twisting under load

What the evidence says: LIFTMOR RCT: 8 months of twice-weekly high-intensity resistance and impact training increased lumbar spine BMD and was safe and well tolerated in postmenopausal women with osteopenia and osteoporosis.

Prevalence basis: DXA-based national estimates

What is going on: Weak or poorly coordinated pelvic floor musculature, often after childbirth or with estrogen loss

Strength work: Core: Pelvic Floor - correct pelvic floor muscle training with progression; Core: Transverse Abdominis as a co-contractor; Glutes: Max

Stretching: Hips: Adductors; Hips: Flexors - a chronically gripped pelvic floor sometimes needs down-training instead

Massage: Not primary

Also worth doing: Bladder training; reduce caffeine

Get it checked if: Blood in urine; recurrent infections; new incontinence with back pain or leg numbness is a red flag for cauda equina

What the evidence says: Cochrane: women doing pelvic floor muscle training were 8x more likely to report cure of stress incontinence (56% vs 6%) and 5x more likely for any incontinence (35% vs 6%). First-line treatment in every guideline.

Prevalence basis: Cochrane review background epidemiology

What is going on: Nerve root irritation from disc material or stenosis; symptoms follow a dermatome below the knee

Strength work: Core: Transverse Abdominis; Glutes: Max; Back: Spinal Erectors - build tolerance without provoking

Stretching: Direction matters: many do better with extension (McKenzie press-up) than flexion; Glutes: Piriformis; Legs: Hamstrings gently only

Massage: Glutes; Back: QL; avoid deep pressure directly over an irritated nerve path

Also worth doing: Nerve glides (sciatic flossing); walking; avoid prolonged sitting

Get it checked if: Bowel or bladder change, saddle numbness, or bilateral leg weakness = cauda equina, EMERGENCY; progressive foot drop needs urgent review

What the evidence says: Most cases settle within 12 weeks. Exercise does not shorten the acute episode much but reduces recurrence. Match exercises to the direction that centralizes symptoms.

Prevalence basis: Population and primary-care studies

What is going on: Hepatic lipid handling and low muscle mass; exercise shifts HDL and triglycerides more than LDL

Strength work: Full Body; combined resistance and aerobic

Stretching: Not a driver

Massage: Not a driver

Also worth doing: Aerobic volume matters more than intensity here

Get it checked if: Chest pain or breathlessness on exertion - stop and get assessed

What the evidence says: Exercise reliably lowers triglycerides and raises HDL; LDL change is small. Honest framing: adjunct to diet and medication, not a replacement.

Prevalence basis: NHANES

What is going on: Central adiposity with low muscle mass drives every component of the cluster

Strength work: Full Body; compound resistance work 3x/week plus aerobic

Stretching: Secondary

Massage: Secondary

Also worth doing: Post-meal walks; sleep

Get it checked if: See the High blood pressure and Prediabetes red flags

What the evidence says: Combined resistance and aerobic training improves every component of the cluster. Resistance training independently improves insulin sensitivity.

Prevalence basis: NHANES

What is going on: Excess hepatic triglyceride from energy surplus and insulin resistance

Strength work: Full Body; resistance training reduces liver fat even without weight loss

Stretching: Not a driver

Massage: Not a driver

Also worth doing: Aerobic exercise; alcohol reduction

Get it checked if: Jaundice, ascites or confusion needs urgent hepatology

What the evidence says: Exercise reduces hepatic fat independent of weight change - one of the clearest exercise-as-medicine findings. Resistance training works at lower energy cost than aerobic, which matters for adherence.

Prevalence basis: Meta-analysis of imaging-based prevalence studies

What is going on: Multifactorial; exercise acts through BDNF, inflammation, self-efficacy and behavioral activation

Strength work: Full Body; resistance training 2-3x/week at moderate intensity

Stretching: Secondary

Massage: Professional Massage as an adjunct

Also worth doing: Outdoor and social exercise adds benefit

Get it checked if: Suicidal ideation - urgent professional help; exercise is an adjunct not a substitute for treatment

What the evidence says: Resistance training reduced depressive symptoms with a moderate effect (around -0.66 SMD) in meta-analysis, independent of strength gained. Effects are largest in those with the highest baseline symptoms.

Prevalence basis: National mental health surveys

What is going on: Overload of the plantar fascia at the calcaneal insertion; almost always with restricted ankle dorsiflexion and weak intrinsics

Strength work: High-load plantar fascia strength - slow heavy calf raise with toes extended on a towel; Legs: Calves: Soleus; Feet, Toes, Ankles; Legs: Calves: Tibialis Posterior; Feet, Toes, Ankles: Intrinsic Foot Muscles

Stretching: Legs: Calves; Legs: Calves: Soleus; Feet, Toes, Ankles; plantar fascia specific stretch; Feet, Toes, Ankles: Plantar Fascia stretch

Massage: Feet, Toes, Ankles; Massage Ball - frozen bottle roll; Legs: Calves; Feet, Toes, Ankles: Plantar Fascia massage

Also worth doing: Supportive footwear; night splint (Physical Therapy item 685); avoid barefoot on hard floors while acute

Get it checked if: Heel pain after trauma; numbness or burning suggests nerve entrapment; bilateral heel pain in a young man may be inflammatory (spondyloarthritis)

What the evidence says: Rathleff RCT: high-load strength training beat plantar-specific stretching alone at 3 months. Stretching helps early; loading is what resolves it.

Prevalence basis: Foot and ankle epidemiology reviews

What is going on: Weakened pelvic floor support allows the bladder, uterus or rectum to descend into the vaginal wall

Strength work: Core: Pelvic Floor - supervised pelvic floor muscle training with progression; Core: Transverse Abdominis; Glutes: Max

Stretching: Hips: Adductors; Hips: Flexors

Massage: Not primary

Also worth doing: Avoid chronic straining and heavy uncontrolled lifting while symptomatic; treat constipation; pessary as a parallel option

Get it checked if: A bulge that cannot be reduced, bleeding, or difficulty emptying the bladder or bowel needs gynecology

What the evidence says: Supervised pelvic floor muscle training improves prolapse symptoms and reduces stage in RCTs. It works best for mild-to-moderate prolapse and is first-line before surgery.

Prevalence basis: Gynecology examination cohorts

What is going on: Collapsible upper airway with low tone in tongue and pharyngeal muscles during sleep

Strength work: Oropharyngeal and tongue exercises - myofunctional therapy; plus general weight-reducing resistance and aerobic work

Stretching: Neck as an adjunct only

Massage: Not primary

Also worth doing: Side sleeping; weight loss; alcohol timing; CPAP remains first-line for moderate-severe OSA

Get it checked if: Witnessed apneas, choking arousals, or falling asleep while driving - needs a sleep study now; do not self-treat moderate-severe OSA

What the evidence says: Meta-analysis: myofunctional therapy reduced AHI by roughly 10 events/hour and Epworth sleepiness by 5.7 points versus sham or no therapy. Certainty is low and it is inferior to CPAP - position it as adjunct or for mild cases.

Prevalence basis: Population polysomnography studies

What is going on: Cartilage loss at the CMC and IP joints with first dorsal interosseous and thenar weakness

Strength work: Hands, Fingers, Forearms, Grip; Arms: Forearms: Wrist Flexors and Extensors; pinch and putty work

Stretching: Hands, Fingers, Wrists

Massage: Hands, Fingers

Also worth doing: Joint protection; thumb spica orthosis for the CMC joint

Get it checked if: Hot swollen joints with morning stiffness over an hour suggests inflammatory arthritis - refer

What the evidence says: Hand exercise programs give small but real improvements in pain and function. Orthoses help the thumb base more than exercise does.

Prevalence basis: Framingham and equivalent cohorts

What is going on: Incompetent lower esophageal sphincter; the crural diaphragm forms part of that sphincter and can be trained

Strength work: Core: Diaphragm - diaphragmatic breathing training; avoid heavy loaded Valsalva while symptomatic

Stretching: Trunk; Chest

Massage: Not primary

Also worth doing: Meal timing; head-of-bed elevation; weight loss

Get it checked if: Difficulty swallowing, vomiting blood, unexplained weight loss, or anemia - urgent endoscopy

What the evidence says: Diaphragmatic breathing training reduced reflux episodes and PPI use in RCTs. Small literature but consistent and low-risk.

Prevalence basis: Systematic reviews of GERD prevalence

What is going on: Neurovascular; the neck is a common trigger and amplifier rather than the cause

Strength work: Neck; Back: Traps: Lower; shoulder-girdle endurance

Stretching: Neck; Shoulders; Neck: Suboccipitals stretch

Massage: Neck & Shoulders; Neck: SCM; Jaw & Face; Neck: Suboccipitals massage

Also worth doing: Regular aerobic exercise 3x/week has trial support; consistent sleep and meals

Get it checked if: Sudden worst-ever headache; new aura after 50; focal deficit that does not resolve; fever with neck stiffness

What the evidence says: Aerobic exercise reduced migraine frequency comparably to topiramate in one RCT. Neck work helps the subset with cervical contribution. Do not overpromise - this is adjunct.

Prevalence basis: Global headache epidemiology

What is going on: Failed venous valves; the calf muscle pump is the main return mechanism and it needs contraction to work

Strength work: Legs: Calves: Gastrocnemius; Legs: Calves: Soleus; calf raises; ankle pumps; walking

Stretching: Legs: Calves; Legs: Hamstrings

Massage: Legs: Calves - light, upward strokes; avoid deep work directly over varicosities

Also worth doing: Compression socks (Physical Therapy item 855); leg elevation (item 913)

Get it checked if: Hot swollen painful calf, especially one-sided after travel or surgery - possible DVT, do NOT massage, urgent assessment; skin ulceration needs vascular review

What the evidence says: Calf-pump exercise and compression improve symptoms and edema. Exercise does not reverse the varicosities themselves - be honest about that.

Prevalence basis: Vein population studies

What is going on: Gravity plus an idle calf pump; fluid pools in the interstitium

Strength work: Legs: Calves; ankle pumps and calf raises every hour

Stretching: Legs: Calves; Feet, Toes, Ankles

Massage: Legs: Calves - upward strokes toward the heart; Feet, Toes, Ankles

Also worth doing: Elevation above heart level; compression; movement breaks

Get it checked if: Sudden one-sided swelling with pain or warmth - possible DVT, urgent, no massage; bilateral swelling with breathlessness - cardiac or renal, urgent

What the evidence says: Simple and effective for gravitational edema. Rule out DVT, heart failure and kidney disease before treating as postural.

Prevalence basis: Occupational health and primary-care data

What is going on: Age-related disc and facet degeneration in the neck. Like disc degeneration in the back, the imaging correlates poorly with symptoms - most people with the changes have no pain

Strength work: Neck; Neck: Splenius; Back: Traps: Lower; Back: Rhomboids - endurance work builds tolerance; Neck: Deep Neck Flexors

Stretching: Neck; Chest; Back: Mid-Back - gentle, within comfort

Massage: Neck & Shoulders; Back: Upper Back

Also worth doing: Keep the neck moving; screen height; the belief that the neck is worn out predicts disability more than the imaging does

Get it checked if: Arm weakness or numbness, clumsy hands, or unsteady walking suggests cord or root involvement - refer

What the evidence says: Strengthening and continued movement work. The most useful thing you can tell someone with a degenerative neck report is how common those findings are in people with no symptoms at all.

Prevalence basis: Cervical imaging cohorts

What is going on: Descending is almost entirely eccentric quadriceps work, at loads several times body weight, in people whose training is all uphill and flat. The quad fatigues, the knee loses control, and the joint takes the shock

Strength work: Legs: Quads - eccentric step-downs and slow tempo squats are the specific preparation; Glutes: Max; Glutes: Med; Legs: Calves

Stretching: Legs: Quads; Legs: Hamstrings; Legs: Calves; Hips: Flexors

Massage: Legs: Quads; Legs: Calves; Hips: Iliotibial (IT) Band

Also worth doing: Trekking poles cut knee load on descent substantially - the single most effective intervention; shorter steps; controlled pace

Get it checked if: Knee swelling, locking or giving way on a descent needs assessment before the next trip

What the evidence says: Eccentric quad training is the specific preparation and it transfers directly. Trekking poles do the rest. Highly relevant to anyone using the trip-planning side of the sites.

Prevalence basis: Wilderness and sports medicine surveys

What is going on: A fixed forward-flexed position for hours with the neck extended to look ahead, plus sustained body weight through the hands compressing the ulnar and median nerves at the wrist

Strength work: Neck; Neck: Deep Neck Flexors; Back: Traps: Lower; Core: Transverse Abdominis; Glutes: Max; Arms: Forearms: Wrist Extensors

Stretching: Neck; Chest; Hips: Flexors; Back: Lower Back; Hands, Fingers, Wrists

Massage: Neck & Shoulders; Back: Upper Back; Arms: Forearms; Hands, Fingers

Also worth doing: Bike fit is the first intervention, not the last; change hand position every few minutes; padded gloves

Get it checked if: Persistent hand numbness or weakness after a ride needs assessment - handlebar palsy can become lasting

What the evidence says: Fit plus core and neck endurance. Hand numbness is a position problem first and a strength problem second - do not train through it.

Prevalence basis: Cycling medicine surveys

What is going on: A high-speed rotational sport played by people who mostly sit. When the hips and thoracic spine will not rotate, the lumbar spine supplies the range at speed, and the lead hip and lead side take the load

Strength work: Abs: Obliques; Core: Transverse Abdominis; Glutes: Max; Glutes: Med; Back: Quadratus Lumborum (QL); anti-rotation work

Stretching: Back: Mid-Back; Spine; Trunk; Hips; Hips: Flexors; Glutes: Piriformis

Massage: Back: Quadratus Lumborum (QL); Glutes; Back: Upper Back

Also worth doing: Warm up before the first tee - the first drive cold is a classic injury moment; thoracic and hip rotation are what protect the back

Get it checked if: Back pain with leg symptoms, or pain that worsens through a round and does not settle overnight, needs review

What the evidence says: Rotation has to come from the hips and thoracic spine or the lumbar spine pays for it. A five-minute rotational warm-up before the first tee is the highest-value habit.

Prevalence basis: Golf medicine surveys

What is going on: Weak thoracic extensors and vertebral wedging; often a marker of undiagnosed vertebral fractures

Strength work: Back: Spinal Erectors; Back: Traps: Lower and Middle; Back: Rhomboids; prone extension work

Stretching: Chest; Back: Lats; Spine - thoracic extension over a roller

Massage: Back: Upper Back; Foam Roller Massage

Also worth doing: Avoid loaded spinal flexion if bone density is low

Get it checked if: Sudden increase in curvature with back pain suggests vertebral fracture - image before loading

What the evidence says: Extensor strengthening improves kyphosis angle modestly and improves function more. Screen for osteoporosis first.

Prevalence basis: Geriatric posture cohorts

What is going on: A vertebral body collapses under low load because bone density is low; it drives the stooped posture and further fracture risk

Strength work: Back: Spinal Erectors - prone and standing extension work; Glutes: Max; Core: Transverse Abdominis; progressive weight-bearing

Stretching: AVOID all loaded spinal flexion and twisting; Chest; Hips: Flexors instead

Massage: Back: Upper Back - light, never over the fracture site

Also worth doing: Balance and fall prevention; bone medication; posture support

Get it checked if: Sudden severe back pain in anyone over 50 with osteoporosis risk needs imaging before any exercise; height loss over 4 cm is a marker

What the evidence says: Extension-based strengthening reduces further fracture risk. Loaded flexion (sit-ups, crunches, toe touches) significantly increases it - this is one of the few genuine exercise contraindications.

Prevalence basis: Vertebral morphometry studies

What is going on: Damaged ligament plus, more importantly, lost proprioception and delayed peroneal reaction time

Strength work: Legs: Calves: Peroneals; Legs: Calves: Tibialis Anterior; Feet, Toes, Ankles; Glutes: Med

Stretching: Legs: Calves; Feet, Toes, Ankles

Massage: Legs: Calves: Peroneals (Fibularis); Feet, Toes, Ankles

Also worth doing: Single-leg balance progressions; wobble board; hop-and-stick; ankle brace during sport (Physical Therapy item 866)

Get it checked if: Inability to weight-bear for four steps after a sprain - Ottawa rules, image for fracture

What the evidence says: Balance and proprioceptive training cuts recurrent sprain risk by roughly half. Best-evidenced injury prevention in sport.

Prevalence basis: Sports injury surveillance

What is going on: Hip abductor and external rotator weakness lets the femur rotate under the patella; quad weakness and stiff lateral structures add to it

Strength work: Glutes: Med; Glutes: Max; Hips: Deep External Rotators; Legs: Quads; step-downs; single-leg squats

Stretching: Legs: Quads; Hips: IT Band; Legs: Hamstrings; Legs: Calves

Massage: Legs: Quads; Hips: IT Band; Hips: TFL

Also worth doing: Cadence increase for runners; load management

Get it checked if: Locking, giving way or effusion suggests internal derangement

What the evidence says: Hip-plus-knee strengthening beats knee-only strengthening in multiple RCTs. This is a strength problem, not a kneecap-tracking problem to be taped away.

Prevalence basis: Patellofemoral pain consensus statements

What is going on: Failed tendon healing response to repeated load; the tendon needs progressive load, not rest

Strength work: Legs: Calves: Gastrocnemius; Legs: Calves: Soleus - slow heavy eccentric heel drops, 3x15 twice daily (Alfredson) or heavy slow resistance

Stretching: Legs: Calves; Legs: Calves: Gastrocnemius; Legs: Calves: Soleus

Massage: Legs: Calves; Massage Stick

Also worth doing: Heel lifts while acute (Physical Therapy item 863); avoid sudden volume jumps

Get it checked if: Sudden pop with inability to push off - suspect rupture, urgent; insertional pain behaves differently and dislikes full dorsiflexion stretching

What the evidence says: Alfredson eccentric protocol has 20+ years of support. Insertional cases need a floor-level (not step) version - stretching into dorsiflexion makes insertional pain worse.

Prevalence basis: Tendinopathy epidemiology reviews

What is going on: Referred pain from upper cervical joints and muscles into the head via the trigeminocervical nucleus

Strength work: Neck; deep cervical flexor endurance (chin tucks); Back: Traps: Lower; Neck: Deep Neck Flexors

Stretching: Neck; suboccipital and upper trap stretch; Neck: Suboccipitals stretch

Massage: Neck & Shoulders; Neck: SCM; suboccipital release; Neck: Suboccipitals massage

Also worth doing: Screen height; pillow height

Get it checked if: Same as tension headache; plus dizziness or visual disturbance on neck movement needs assessment

What the evidence says: Combined manual therapy plus specific neck exercise beats either alone and holds at 12 months.

Prevalence basis: Headache classification epidemiology

What is going on: Masticatory muscle overactivity and joint loading, often with clenching and neck involvement

Strength work: Gentle controlled jaw opening and resisted opening; Neck as the postural partner

Stretching: Jaw opening range work; Neck; Chest

Massage: Jaw & Face TMJ; Neck & Shoulders; masseter and temporalis release

Also worth doing: Soft diet while acute; stop gum; tongue-to-palate resting posture

Get it checked if: Jaw locking closed or open; facial numbness; jaw pain with exertion can be cardiac in women - take that seriously

What the evidence says: Self-managed jaw exercise plus masseter self-massage matches splint therapy in several trials at far lower cost.

Prevalence basis: Orofacial pain epidemiology

What is going on: Narrowed leg arteries cannot meet muscle oxygen demand during walking; the calf cramps and forces a stop

Strength work: Legs: Calves: Gastrocnemius; Legs: Calves: Soleus; Legs: Quads; Glutes

Stretching: Legs: Calves

Massage: Legs: Calves - light only

Also worth doing: Structured walking to near-maximal claudication pain, rest, repeat, 30-45 min three times a week for 12 weeks; smoking cessation

Get it checked if: Rest pain, non-healing wounds, or a cold pale foot is critical limb ischemia - urgent vascular referral. Do NOT push through that

What the evidence says: Supervised exercise therapy is first-line and improves walking distance as much as stenting at far lower cost and risk. The counterintuitive part is that you walk INTO the pain - that is the stimulus.

Prevalence basis: Vascular epidemiology

What is going on: Sleep and awake bruxism; masseter and temporalis hypertrophy with sustained load

Strength work: Gentle jaw and neck postural work only - do not strengthen a muscle that is already over-contracting

Stretching: Jaw opening range; Neck

Massage: Jaw & Face TMJ; masseter and temporalis release; Neck & Shoulders

Also worth doing: Stress management; tongue-to-palate rest position; dental guard

Get it checked if: Worn or cracked teeth need a dentist; sleep bruxism with snoring may signal apnea - see the Snoring and obstructive sleep apnea entry

What the evidence says: Massage and relaxation training reduce muscle pain from bruxism. Nothing reliably stops the grinding itself - a guard protects the teeth.

Prevalence basis: Sleep and dental epidemiology

What is going on: Raised pressure in the carpal tunnel compressing the median nerve; worse with sustained wrist flexion or extension

Strength work: Arms: Forearms: Wrist Flexors; Wrist Extensors; Hands, Fingers, Forearms, Grip - build tolerance, do not aggravate

Stretching: Hands, Fingers, Wrists

Massage: Arms: Forearms; Hands, Fingers

Also worth doing: Night wrist splint in neutral is first-line; median nerve and tendon gliding; keyboard and mouse setup

Get it checked if: Constant numbness, thenar wasting or weakness means it is advanced - surgical referral, do not delay with exercises

What the evidence says: Splinting has the best evidence; nerve and tendon gliding is a reasonable low-cost adjunct. Do not promise resolution of established denervation.

Prevalence basis: Population nerve-conduction studies

What is going on: Insulin resistance drives androgen excess; skeletal muscle is the main lever on insulin sensitivity

Strength work: Full Body; Legs: Quads; Glutes; resistance training 2-3x/week

Stretching: Secondary

Massage: Secondary

Also worth doing: Aerobic exercise; sleep; the benefit appears even without weight loss

Get it checked if: New or worsening irregular cycles, or difficulty conceiving, needs endocrine and gynecology input alongside exercise

What the evidence says: Exercise is first-line in the international PCOS guideline. Resistance training improves insulin sensitivity and androgen profile independent of weight change - important because weight-loss-only advice fails this group repeatedly.

Prevalence basis: International PCOS guideline estimates

What is going on: Capsular fibrosis and contracture; a three-stage condition (freezing, frozen, thawing) that runs 12-30 months

Strength work: Shoulders: Rotator Cuff; Back: Traps: Lower - within pain-free range only

Stretching: Shoulders; pendulum, table slides, wall walks, external rotation at the doorway

Massage: Back: Upper Back; Shoulders: Rotator Cuff

Also worth doing: Pace to irritability; aggressive stretching in the freezing stage makes it worse

Get it checked if: Sudden loss of all movement after trauma; ask about diabetes and thyroid - both are strongly associated

What the evidence says: Stage matters more than exercise choice. Gentle ROM within tolerance in stage 1; more aggressive stretching only once irritability drops. Over-stretching early prolongs it.

Prevalence basis: Shoulder epidemiology; strong diabetes association

What is going on: Calcium hydroxyapatite deposits in the cuff tendon, most often supraspinatus; acutely resorbing deposits cause severe pain

Strength work: Shoulders: Rotator Cuff; Supraspinatus; Back: Traps: Lower - gentle during the acute phase, progressive after

Stretching: Shoulders; Chest - avoid forcing range while acutely painful

Massage: Back: Upper Back; Shoulders: Rotator Cuff

Also worth doing: Barbotage or shockwave for resistant cases; the acute resorptive phase is self-limiting but extremely painful

Get it checked if: Severe unremitting shoulder pain with fever needs infection excluded; the acute resorptive phase can be mistaken for a septic joint

What the evidence says: Most deposits resorb spontaneously. Exercise maintains function through it; it does not dissolve the calcium. Be honest about that or the routine overpromises.

Prevalence basis: Shoulder imaging studies

What is going on: Compressive tendinopathy of gluteus medius and minimus at the trochanter, made worse by hip adduction (crossing legs, hanging on one hip, side-lying)

Strength work: Glutes: Med; Glutes: Min; Glutes: Max - isometric abduction first, then progressive loading

Stretching: AVOID IT band and figure-4 stretches - they compress the tendon; Hips: Flexors instead

Massage: Glutes: Med; avoid direct pressure over the trochanter

Also worth doing: Stop crossing legs; pillow between knees at night; avoid hanging on one hip when standing

Get it checked if: Night pain that prevents lying on either side and does not settle needs imaging

What the evidence says: LEAP RCT: education plus exercise beat corticosteroid injection at 8 weeks and at 52 weeks. IMPORTANT: the classic IT band stretch makes this worse - flag that in the routine.

Prevalence basis: Primary-care incidence data

What is going on: Narrowed canal compresses the cauda equina; symptoms come on with walking and extension, ease with sitting and flexion

Strength work: Core: Transverse Abdominis; Glutes: Max; Legs: Quads

Stretching: Flexion bias helps - knees to chest, seated flexion; Hips: Flexors; AVOID sustained extension

Massage: Back: QL; Glutes

Also worth doing: Cycling or inclined treadmill (flexed positions) for cardio; walking with a stick or trolley

Get it checked if: Bowel or bladder change or saddle numbness = cauda equina, EMERGENCY; progressive leg weakness needs urgent review

What the evidence says: Exercise and manual therapy match surgery for mild-to-moderate cases at 2 years. Direction of preference is the whole game - flexion for stenosis, often extension for disc.

Prevalence basis: Imaging and symptom-based cohorts

What is going on: Sciatic nerve irritation as it passes the deep hip rotators; often from sitting on a wallet or prolonged sitting

Strength work: Glutes: Med; Glutes: Max; Hips: Deep External Rotators

Stretching: Glutes: Piriformis; Glutes; figure-4 and 90/90 positions

Massage: Glutes; Massage Ball - seated ball work on the glute

Also worth doing: Stop sitting on a wallet; standing breaks

Get it checked if: Numbness below the knee or foot drop points at a lumbar root instead - reassess

What the evidence says: Stretching plus strengthening of the hip rotators helps; the diagnosis itself is contested, so treat the symptoms and the sitting habit.

Prevalence basis: Clinical series

What is going on: Lost terminal knee flexion from capsular tightness, quadriceps shortening or scar, plus a genuine fear of loading the kneecap. The range is usually more available than it feels

Strength work: Legs: Quads; Glutes: Max; Legs: Hamstrings; progressive loaded knee flexion; half-kneeling holds

Stretching: Legs: Quads - the rectus femoris limits flexion when the hip is extended; Legs: Calves; Feet, Toes, Ankles - kneeling needs ankle range too

Massage: Legs: Quads; scar mobilization if there has been surgery

Also worth doing: Kneel on a folded towel or pad and progress the load gradually; practise little and often

Get it checked if: Sudden loss of knee flexion with swelling, or a knee that cannot be straightened, needs assessment

What the evidence says: Range plus graded exposure to the pressure. Worth its own routine because the loss is functional and specific, and most knee programs never address terminal flexion at all.

Prevalence basis: Functional knee outcome studies

What is going on: Load transfer failure across the pelvis; common postpartum and in hypermobility

Strength work: Glutes: Max; Glutes: Med; Core: Transverse Abdominis; Hips: Adductors - compression and stability, not mobilization

Stretching: Hips: Flexors; Glutes: Piriformis; go easy - too much stretching destabilizes

Massage: Back: QL; Glutes

Also worth doing: SI belt while symptomatic; avoid single-leg loading tasks (putting on trousers standing)

Get it checked if: Bilateral inflammatory back pain in a young adult with morning stiffness over 30 min - screen for axial spondyloarthritis (see the Inflammatory back pain in young adults entry)

What the evidence says: Stability and strength beat mobilization for most. Hypermobile people get worse with stretching - screen for that first.

Prevalence basis: Diagnostic block studies

What is going on: Weak foot intrinsics and tibialis posterior allow the arch to collapse under load

Strength work: Feet, Toes, Ankles; Legs: Calves: Tibialis Posterior; Legs: Calves: Tibialis Anterior; short-foot and heel-raise-with-inversion work; Feet, Toes, Ankles: Intrinsic Foot Muscles

Stretching: Legs: Calves; Feet, Toes, Ankles

Massage: Feet, Toes, Ankles

Also worth doing: Supportive or orthotic footwear; progress barefoot work slowly

Get it checked if: Painful, rigid, or newly collapsed arch in an adult suggests posterior tibial tendon dysfunction - refer early, it progresses

What the evidence says: Flat feet only need treating if they hurt. Foot and tib-post strengthening improves symptomatic cases; it does not rebuild an arch.

Prevalence basis: Foot morphology studies

What is going on: Progressive failure of the tibialis posterior tendon, the main dynamic support of the arch; it progresses through rigid deformity if untreated

Strength work: Legs: Calves: Tibialis Posterior - heel raises with inversion, the single most important exercise; Feet, Toes, Ankles; Glutes: Med; Feet, Toes, Ankles: Intrinsic Foot Muscles

Stretching: Legs: Calves; Legs: Calves: Gastrocnemius - a tight calf drives this

Massage: Legs: Calves; Feet, Toes, Ankles

Also worth doing: Orthotic support; a stiff-soled shoe; catching it in stage 1 or 2 avoids surgery

Get it checked if: A flattening arch with pain behind the inner ankle that you cannot do a single-leg heel raise on is stage 2 or worse - refer, this progresses

What the evidence says: Eccentric heel raises with orthoses resolve most stage 1 and 2 cases. Delay means a rigid deformity that only surgery corrects - so early recognition is the whole game.

Prevalence basis: Foot and ankle epidemiology

What is going on: Loss of plantar fat pad cushioning plus forefoot overload from tight calves, high heels or a stiff big toe

Strength work: Feet, Toes, Ankles; Toe Neuromuscular Exercises; Legs: Calves: Soleus; Feet, Toes, Ankles: Intrinsic Foot Muscles

Stretching: Legs: Calves; Feet, Toes, Ankles; Feet, Toes, Ankles: Plantar Fascia stretch

Massage: Feet, Toes, Ankles; Massage Ball - gentle, the pad is already thin; Feet, Toes, Ankles: Plantar Fascia massage

Also worth doing: Metatarsal pad placed proximal to the painful heads; cushioned footwear

Get it checked if: Burning or electric pain between the toes suggests a neuroma; numbness suggests neuropathy

What the evidence says: Padding and footwear do most of the work; calf and intrinsic strengthening reduce forefoot load. Fat pad thickness cannot be restored by exercise.

Prevalence basis: Foot pain cohort studies

What is going on: Progressive first-MTP joint deviation, driven by footwear and by weakness of the abductor hallucis

Strength work: Feet, Toes, Ankles; Toe Neuromuscular Exercises; toe abduction and short-foot work; Feet, Toes, Ankles: Intrinsic Foot Muscles

Stretching: Feet, Toes, Ankles; big toe mobilization

Massage: Feet, Toes, Ankles; Massage Ball

Also worth doing: Wear Toe Spacers; wide toe-box shoes

Get it checked if: Sudden hot swollen big toe joint is more likely gout than bunion - different treatment entirely

What the evidence says: Exercise and spacers slow progression and reduce pain; they do not straighten an established bunion. Say so plainly or the routine will disappoint.

Prevalence basis: Foot deformity meta-analysis

What is going on: Urate crystals in a joint causing sudden intense inflammation, most classically the big toe. Between attacks the joint is normal; during one it is exquisitely painful

Strength work: BETWEEN attacks: Full Body and weight management reduce attack frequency. DURING an attack: nothing

Stretching: Not during an attack

Massage: NEVER massage an acutely gouty joint - it is intensely painful and massage does nothing for crystal inflammation

Also worth doing: Urate-lowering medication is the actual treatment; reduce alcohol and high-purine intake; treat the metabolic syndrome that usually accompanies it

Get it checked if: A hot swollen single joint could be SEPTIC ARTHRITIS rather than gout, which is a surgical emergency. Never assume gout; a first presentation needs medical assessment

What the evidence says: Listed as a caution entry. Exercise and weight management reduce attack frequency, but nothing in this app should be recommended during a flare, and a hot single joint always needs a diagnosis first.

Prevalence basis: Rheumatology epidemiology

What is going on: Imbalance between long flexors and weak intrinsic toe muscles causes the toe to buckle at the joints

Strength work: Feet, Toes, Ankles; Toe Neuromuscular Exercises; toe extension and spreading work; Feet, Toes, Ankles: Intrinsic Foot Muscles

Stretching: Feet, Toes, Ankles; toe extension stretch

Massage: Feet, Toes, Ankles; Massage Ball

Also worth doing: Wear Toe Spacers; deep toe-box footwear; toe crest pads

Get it checked if: A rigid toe that cannot be straightened by hand will not respond to exercise; ulceration on the toe top needs urgent care in a diabetic

What the evidence says: Flexible deformities improve with intrinsic strengthening and spacers. Rigid ones do not - check flexibility before recommending.

Prevalence basis: Foot deformity studies

What is going on: Dopaminergic and iron-handling dysfunction in the CNS; movement temporarily relieves the urge

Strength work: Full Body at moderate intensity; Legs: Quads; Legs: Calves - avoid vigorous exercise close to bedtime

Stretching: Legs: Calves; Legs: Hamstrings; Hips: Flexors - before bed

Massage: Legs: Calves; Legs: Quads; Foam Roller Massage

Also worth doing: Check ferritin - iron deficiency is a common reversible cause

Get it checked if: Sudden onset or one-sided symptoms are not RLS; check iron studies and medications

What the evidence says: A 12-week exercise RCT reduced RLS symptom severity substantially. Stretching and massage before bed help symptomatically.

Prevalence basis: Sleep medicine epidemiology

What is going on: Reduced cardiac output plus, importantly, peripheral skeletal muscle dysfunction that drives much of the exercise intolerance

Strength work: Legs: Quads; Glutes; Full Body - moderate-intensity resistance training is safe and recommended

Stretching: Full Body

Massage: Legs: Calves - light, upward strokes

Also worth doing: Supervised aerobic training; inspiratory muscle training; daily weight monitoring

Get it checked if: Weight gain of 2 kg in days, worsening breathlessness lying flat, or new ankle swelling means decompensation - stop and get reviewed before exercising

What the evidence says: HF-ACTION and subsequent trials: exercise training reduces hospitalization and improves quality of life. Resistance training is safe and no longer contraindicated. Needs medical clearance and stable status.

Prevalence basis: Cardiology epidemiology

What is going on: Deconditioning plus fear of exertion after an event; the muscle and vascular adaptations are what restore capacity

Strength work: Full Body; Legs: Quads; Back: Lats; progressive resistance work from about 2-3 weeks post-event as cleared

Stretching: Full Body; Chest

Massage: Professional Massage for anxiety

Also worth doing: Structured aerobic progression; risk factor management; the psychological component matters as much as the physical

Get it checked if: Any chest pain, unusual breathlessness or palpitations during exercise - stop and seek review. Exercise must be started under cardiac rehab guidance, not self-directed

What the evidence says: Cardiac rehabilitation reduces cardiovascular mortality by roughly a quarter. It is one of the highest-value interventions in medicine and is chronically under-used.

Prevalence basis: Cardiology outcome data

What is going on: Atrial remodeling driven by hypertension, obesity, sleep apnea and alcohol - most of which exercise addresses

Strength work: Full Body; moderate resistance training; Legs: Quads

Stretching: Secondary

Massage: Secondary

Also worth doing: Aerobic training; weight loss; treating sleep apnea; reducing alcohol - the LEGACY and CARDIO-FIT studies show risk factor management reduces AF burden

Get it checked if: Palpitations with chest pain, fainting or severe breathlessness - urgent. Very high-volume endurance exercise paradoxically increases AF risk in athletes

What the evidence says: Moderate exercise plus weight loss substantially reduces AF burden and recurrence. The dose-response is U-shaped - extreme endurance volume increases risk, so do not frame more as better.

Prevalence basis: Cardiology registries

What is going on: Estrogen loss accelerates bone and muscle loss, shifts fat distribution, and disrupts sleep and thermoregulation

Strength work: Heavy resistance training - see the Osteoporosis and osteopenia protocol; Full Body; Glutes; Legs: Quads

Stretching: Full Body; Spine

Massage: Professional Massage; Neck & Shoulders

Also worth doing: Balance and impact work for bone; sleep hygiene; strength beats cardio for body composition here

Get it checked if: Postmenopausal bleeding always needs investigation

What the evidence says: Resistance training protects bone and lean mass through the transition. Evidence for exercise reducing hot flashes specifically is mixed - do not lead with that claim.

Prevalence basis: Menopause society estimates

What is going on: Relaxin-mediated ligament laxity plus a rapidly shifting center of mass; the deep core and glutes cannot keep up

Strength work: Glutes: Max; Glutes: Med; Core: Transverse Abdominis; Core: Pelvic Floor

Stretching: Hips: Flexors; Glutes: Piriformis; Hips: Adductors - gently, laxity is already high

Massage: Back: QL; Glutes; avoid deep pressure over the sacrum in the first trimester

Also worth doing: Pelvic support belt; side-lying with a pillow between knees; avoid single-leg loading

Get it checked if: Bleeding, leaking fluid, reduced fetal movement, severe headache or visual change - urgent obstetric review

What the evidence says: Exercise in pregnancy reduces back pain and is safe in uncomplicated pregnancies. Pelvic girdle pain responds to stability work, not stretching.

Prevalence basis: Obstetric cohort studies

What is going on: Linea alba stretched and thinned; the issue is load transfer and tension, not the gap width itself

Strength work: Core: Transverse Abdominis; Core: Pelvic Floor; Glutes: Max; progressive loading including eventual curl-ups once tension is restored

Stretching: Hips: Flexors; Back: Lower Back

Massage: Not primary

Also worth doing: Breathing coordination with the deep core; progressive return to loaded work

Get it checked if: Doming or coning under load means the load is too high for now; hernia (a palpable defect with a bulge that will not reduce) needs surgical review

What the evidence says: Modern evidence says gap width matters less than the ability to generate tension. Curl-ups are not forbidden - they are a progression, not a mistake.

Prevalence basis: Postpartum imaging studies

What is going on: Multifactorial - hormonal shift, sleep fragmentation, isolation and the physical toll of recovery

Strength work: Full Body; Glutes: Max; Core: Transverse Abdominis - short, achievable sessions that fit a newborn schedule

Stretching: Neck; Chest; Back: Lower Back - counter the feeding and carrying posture

Massage: Neck & Shoulders; Back: Upper Back; Professional Massage

Also worth doing: Pram walking and group exercise add a social component that appears to carry real weight

Get it checked if: Thoughts of harming yourself or the baby need urgent help immediately - exercise is an adjunct, never the treatment for that

What the evidence says: Exercise reduces postnatal depressive symptoms in meta-analysis, with pram-walking and group formats performing well. Sessions must be short and interruptible or adherence collapses.

Prevalence basis: Perinatal mental health studies

What is going on: Bearing body weight on a hand at end-range wrist extension, in a wrist that has neither the range nor the strength for it. Usually a capacity problem rather than an injury

Strength work: Arms: Forearms: Wrist Extensors; Wrist Flexors; Arms: Forearms: Pronators and Supinators; Hands, Fingers, Forearms, Grip - loaded wrist work builds the tolerance the position needs

Stretching: Hands, Fingers, Wrists - both directions, and progressively into extension

Massage: Arms: Forearms; Hands, Fingers

Also worth doing: Use fists, parallettes or dumbbell handles to keep the wrist neutral while capacity builds; Parallettes Workout exists as an item

Get it checked if: Wrist pain after a fall onto an outstretched hand needs imaging - scaphoid fractures are missed constantly and heal badly when they are

What the evidence says: Progressive loaded wrist work solves this in weeks. The neutral-wrist workaround lets training continue meanwhile, which is what keeps people from quitting.

Prevalence basis: Sports and exercise medicine observation

What is going on: Vascular and pelvic floor components; ischiocavernosus and bulbospongiosus maintain rigidity

Strength work: Core: Pelvic Floor - pelvic floor muscle training; Full Body; aerobic work for endothelial function

Stretching: Hips: Flexors; Hips: Adductors

Massage: Not primary

Also worth doing: Cardiovascular risk factor management - ED is often the first sign of vascular disease

Get it checked if: New ED is a cardiovascular warning sign - it often precedes coronary events by 3-5 years; recommend a medical check

What the evidence says: Dorey RCT: pelvic floor muscle training restored normal function in 40% and improved it in a further 35% at 6 months, matching the comparison intervention.

Prevalence basis: Male sexual health surveys

What is going on: Running is high-impact loading through a pelvic floor and abdominal wall that are still recovering, on top of sleep deprivation and altered load tolerance. Going back on a calendar date rather than on capacity is what causes problems

Strength work: Core: Pelvic Floor; Core: Transverse Abdominis; Glutes: Max; Glutes: Med; Legs: Calves - single-leg strength criteria before running, not weeks on a calendar

Stretching: Hips: Flexors; Legs: Hamstrings; Legs: Calves

Massage: Back: Quadratus Lumborum (QL); Legs: Calves; Glutes

Also worth doing: Recommended guidance is roughly 12 weeks minimum plus meeting strength and symptom criteria: walking, single-leg balance, single-leg calf raises, hopping and running-specific loads without leaking or heaviness

Get it checked if: Leaking, heaviness or dragging in the pelvis, or bleeding, means stop and see a pelvic health physiotherapist - pushing through establishes a lasting problem

What the evidence says: Criteria-based return beats a calendar date. This is a genuinely preventive routine: the strength work before the first run is what avoids the incontinence and prolapse that otherwise start here.

Prevalence basis: Postpartum sports medicine guidance

What is going on: Detrusor overactivity; pelvic floor contraction can reflexively inhibit the detrusor (urge suppression)

Strength work: Core: Pelvic Floor - quick-flick contractions for urge suppression plus endurance holds

Stretching: Hips: Adductors; Hips: Flexors

Massage: Not primary

Also worth doing: Bladder training with timed voiding; reduce caffeine and alcohol

Get it checked if: Blood in urine, pain, or fever needs assessment before behavioral treatment

What the evidence says: Pelvic floor training plus bladder retraining is first-line before medication. Distinct technique from stress incontinence - quick flicks, not just long holds.

Prevalence basis: Urology population studies

What is going on: Weak or poorly coordinated anal sphincter and pelvic floor, often after obstetric injury

Strength work: Core: Pelvic Floor - pelvic floor and sphincter training, ideally with biofeedback; Core: Transverse Abdominis

Stretching: Hips: Adductors

Massage: Not primary

Also worth doing: Stool consistency management; bowel retraining; biofeedback improves results substantially

Get it checked if: New bowel incontinence with back pain or leg numbness is a cauda equina red flag; blood or sudden change needs colorectal review

What the evidence says: Pelvic floor muscle training with biofeedback is first-line conservative treatment. Under-reported because people do not raise it - naming it in an app is itself useful.

Prevalence basis: Colorectal and continence surveys

What is going on: Loss of small-fiber sensation removes the feedback balance depends on; intrinsic foot muscles waste

Strength work: Feet, Toes, Ankles; Legs: Calves; Legs: Quads; Glutes: Med

Stretching: Feet, Toes, Ankles; Legs: Calves

Massage: Feet, Toes, Ankles - light only, sensation is unreliable

Also worth doing: Balance training with visual compensation; daily foot inspection; well-fitted shoes

Get it checked if: Any foot ulcer, wound or color change in a person with neuropathy is urgent - they cannot feel damage; never use heat or a massage gun on numb feet

What the evidence says: Exercise improves balance and may improve nerve function modestly. The fall prevention benefit is the main prize.

Prevalence basis: Neurology and diabetes cohorts

What is going on: Uremic sarcopenia and inflammation cause disproportionate muscle wasting and exercise intolerance

Strength work: Full Body; Legs: Quads; Glutes; resistance training counteracts the muscle wasting

Stretching: Full Body

Massage: Light general work; avoid deep work on a limb with a dialysis fistula

Also worth doing: Aerobic work; intradialytic exercise where relevant; blood pressure control

Get it checked if: Cramping, severe fatigue, or breathlessness may reflect electrolyte or fluid problems - review before continuing

What the evidence says: Resistance training improves muscle mass, function and quality of life in CKD, including in dialysis patients. Safe at all stages with appropriate progression.

Prevalence basis: National kidney surveillance

What is going on: Reduced or asymmetric vestibular input; the brain must be retrained through repeated exposure to the movements that provoke symptoms

Strength work: Neck; Glutes: Med; Legs: Quads for the balance component

Stretching: Neck - a stiff neck compounds the problem

Massage: Neck & Shoulders

Also worth doing: Vestibular rehabilitation: gaze stabilization drills, habituation exercises and progressive balance work. Symptoms must be provoked mildly for adaptation to happen

Get it checked if: Dizziness with hearing loss, double vision, slurred speech or weakness is not vestibular - emergency. Brief spinning on rolling over is BPPV and needs a repositioning maneuver instead

What the evidence says: Vestibular rehabilitation is genuinely exercise therapy and it is first-line with strong evidence. Distinct from BPPV, which needs a maneuver - and distinguishing the two is what makes the recommendation safe.

Prevalence basis: Vestibular medicine epidemiology

What is going on: Weakness and slowing of the suprahyoid and pharyngeal muscles - a form of sarcopenia in muscles nobody thinks to train

Strength work: Suprahyoid strengthening - the Shaker head-lift and chin-tuck-against-resistance exercises; plus general Full Body resistance work, because whole-body sarcopenia and swallowing weakness travel together

Stretching: Neck gently

Massage: Neck & Shoulders

Also worth doing: Speech and language therapy assessment first; posture at meals; food texture as advised

Get it checked if: Coughing or choking on food or drink, recurrent chest infections, or unexplained weight loss needs a swallowing assessment BEFORE any exercise - aspiration is dangerous

What the evidence says: Shaker and chin-tuck-against-resistance exercises improve swallowing function in trials. Must follow a proper assessment - this is one where getting it wrong causes aspiration pneumonia.

Prevalence basis: Geriatric and speech pathology studies

What is going on: Vascular health, BDNF, and cognitive reserve; strength and balance training show effects beyond aerobic alone

Strength work: Full Body; progressive resistance training 2-3x/week

Stretching: Secondary

Massage: Secondary

Also worth doing: Aerobic exercise; dual-task work (counting while balancing); social exercise

Get it checked if: New rapid cognitive change needs medical assessment - it is not always dementia

What the evidence says: Resistance training improved cognition in the SMART trials with effects persisting at 12 months. Exercise is the strongest modifiable dementia risk factor.

Prevalence basis: Dementia prevalence estimates

What is going on: Disuse atrophy at up to 1-3% of muscle mass per day of bed rest, plus inflammatory catabolism

Strength work: Sit-to-stand progressions; Legs: Quads; Glutes; Full Body; Chair Workout

Stretching: Full Body; Hips: Flexors

Massage: Foam Roller Massage; Legs: Calves

Also worth doing: Balance work; protein; early mobilization

Get it checked if: Chest pain, new breathlessness, or a hot swollen calf after surgery - urgent

What the evidence says: Early progressive resistance training reverses disuse atrophy faster than anything else. Start seated if needed.

Prevalence basis: Geriatric medicine data

What is going on: Immobilized connective tissue shortens and joint capsules tighten within weeks, while the muscles around the joint waste at the same time. Both are reversible, but the window matters - the longer stiffness persists, the harder it is to recover

Strength work: Region-specific strength: for a wrist, Arms: Forearms: Wrist Flexors and Extensors and Hands, Fingers, Forearms, Grip; for an ankle, Legs: Calves and Feet, Toes, Ankles; for a shoulder, Shoulders: Rotator Cuff

Stretching: The priority modality here. Region-specific stretch item, little and often - several short sessions daily beats one long one; Hands, Fingers, Wrists; Feet, Toes, Ankles; Shoulders

Massage: Region-specific massage plus scar work once healed; Arms: Forearms; Legs: Calves; Feet, Toes, Ankles

Also worth doing: Start the moment the cast or sling comes off and you are cleared; heat before, movement during, ice after if swollen

Get it checked if: Increasing pain, swelling, color change or burning after a fracture can be complex regional pain syndrome - early recognition matters enormously. Do not push through escalating pain

What the evidence says: One of the clearest wins for stretching on this whole list: the tissue really has shortened, and frequent gentle range work reverses it. Range first, strength close behind - waiting until it is comfortable to move costs range you may not get back.

Prevalence basis: Fracture rehabilitation literature

What is going on: Pre-operative weakness predicts post-operative function; quadriceps strength after knee replacement often never fully recovers without deliberate training

Strength work: Legs: Quads; Glutes: Max; Glutes: Med; Legs: Hamstrings; start BEFORE surgery

Stretching: Legs: Quads; Hips: Flexors; Legs: Hamstrings; knee extension range is the priority after a knee replacement

Massage: Legs: Quads - not over the incision until fully healed

Also worth doing: Balance work; walking progression; range-of-motion targets in the first six weeks matter most

Get it checked if: Fever, wound discharge, calf pain or sudden loss of range after surgery - urgent, could be infection or DVT

What the evidence says: Prehabilitation improves post-operative function and shortens stay. Quadriceps strength deficits persist for years after knee replacement unless specifically trained.

Prevalence basis: Joint registry data

What is going on: Deconditioning, autonomic dysregulation and breathing pattern disorder, in the subgroup that does NOT crash after exertion

Strength work: Full Body - very gradual progression; Legs: Quads; Core: Transverse Abdominis

Stretching: Full Body; Chest

Massage: Foam Roller Massage; Professional Massage

Also worth doing: Breathing retraining; graded return with a symptom diary to detect PEM early

Get it checked if: SCREEN FOR POST-EXERTIONAL MALAISE FIRST. If symptoms worsen 12-72 hours after activity, this is the wrong entry - use the PEM-safe entry instead and do not progress

What the evidence says: Graded exercise helps the deconditioned phenotype and harms the PEM phenotype. Separating the two before recommending anything is the entire safety question.

Prevalence basis: Post-viral illness cohorts

What is going on: Central sensitization - amplified pain processing rather than tissue damage

Strength work: Full Body - start very low and progress very slowly; resistance training is guideline first-line

Stretching: Full Body; gentle whole-body mobility

Massage: Professional Massage; Foam Roller Massage - light pressure only

Also worth doing: Pacing; sleep; graded aerobic work; warm water exercise

Get it checked if: Sudden new focal weakness, joint swelling or fever is not fibromyalgia - reassess

What the evidence says: EULAR makes exercise the only strong first-line recommendation. Massage with sessions of 5+ weeks improved pain, anxiety and depression in meta-analysis, though reviews disagree. Start lower than feels reasonable - flare-ups kill adherence.

Prevalence basis: Rheumatology criteria-based estimates

What is going on: Degenerative tendinopathy of the common extensor origin, usually extensor carpi radialis brevis

Strength work: Arms: Forearms: Wrist Extensors - slow eccentric wrist extension; Hands, Fingers, Forearms, Grip; Back: Rhomboids for the kinetic chain

Stretching: Hands, Fingers, Wrists - wrist flexion stretch with the elbow straight

Massage: Arms: Forearms

Also worth doing: Counterforce brace; reduce sustained gripping

Get it checked if: Numbness in the ring and little finger means the ulnar nerve, not the tendon; night pain and swelling needs review

What the evidence says: Eccentric and heavy-slow loading beats rest, ultrasound and injection in the medium term. Corticosteroid gives short-term relief and worse 12-month outcomes.

Prevalence basis: Elbow disorder epidemiology

What is going on: Age-related meniscal degeneration; usually part of early osteoarthritis rather than a discrete injury

Strength work: Legs: Quads; Glutes: Med; Legs: Hamstrings; Legs: Calves

Stretching: Legs: Quads; Legs: Hamstrings; Legs: Calves

Massage: Legs: Quads; Legs: Hamstrings

Also worth doing: Load management; this is the same program as knee OA

Get it checked if: True mechanical locking (cannot straighten the knee) is the one presentation that may need surgery

What the evidence says: METEOR and FIDELITY trials: exercise therapy matched arthroscopic partial meniscectomy for degenerative tears. This is one of the strongest exercise-over-surgery findings in medicine.

Prevalence basis: Imaging prevalence studies

What is going on: Poor neuromuscular control on landing and cutting - knee collapsing inward with a stiff-legged landing and hamstring-to-quadriceps imbalance

Strength work: Legs: Hamstrings - Nordic curls; Glutes: Med; Glutes: Max; Legs: Quads; Core: Transverse Abdominis

Stretching: Legs: Quads; Hips: Flexors; Legs: Calves

Massage: Legs: Quads; Legs: Hamstrings

Also worth doing: Landing mechanics drills, plyometrics and change-of-direction training - the FIFA 11+ and PEP programs

Get it checked if: A pop with immediate swelling and giving way needs orthopedic assessment; return to sport before 9 months markedly increases re-injury risk

What the evidence says: Neuromuscular prevention programs cut ACL injury rates by roughly half, and by more in women. This is one of the best-evidenced prevention programs in sport and it takes 15 minutes before training.

Prevalence basis: Sports injury registries

What is going on: Bone stress reaction along the posteromedial tibia from a rapid increase in impact load

Strength work: Legs: Calves: Soleus; Legs: Calves: Tibialis Anterior; Legs: Calves: Tibialis Posterior; Glutes: Med

Stretching: Legs: Calves; Legs: Calves: Soleus

Massage: Legs: Calves; Legs: Calves: Tibialis Anterior; Massage Stick

Also worth doing: Load management is the treatment; running surface and cadence

Get it checked if: Focal point tenderness on the bone, night pain, or pain that worsens through a run suggests a stress fracture - stop running and image

What the evidence says: Load management does the work; calf and hip strengthening reduces recurrence. Nothing treats it while the running volume stays high.

Prevalence basis: Sports medicine incidence data

What is going on: Compression of the fat pad under the distal IT band, driven by hip abductor weakness and hip adduction during stance

Strength work: Glutes: Med; Glutes: Max; Hips: Abductors; Hips: TFL; side-lying abduction and hip hitch

Stretching: Hips: IT Band; Hips: Flexors; Glutes

Massage: Hips: IT Band; Hips: TFL - work the TFL and glutes, not the band itself

Also worth doing: Cadence increase; avoid cambered roads and downhills while irritable

Get it checked if: Lateral knee pain with instability or a click may be meniscal

What the evidence says: Hip abductor strengthening is the treatment. The IT band cannot be lengthened - foam rolling gives short-term symptom relief only, so do not build the routine around it.

Prevalence basis: Running injury surveillance

What is going on: Eccentric overload at high speed; the biceps femoris long head fails most often; prior injury is the biggest risk factor

Strength work: Legs: Hamstrings - Nordic curls are the key exercise; Glutes: Max; hip-hinge patterns; Romanian deadlift

Stretching: Legs: Hamstrings; Hips: Flexors - gentle, do not stretch an acute strain

Massage: Legs: Hamstrings; Foam Roller Massage

Also worth doing: Sprint exposure as part of return to play

Get it checked if: Sudden pop with bruising high in the buttock may be a proximal avulsion - surgical window is short, refer within days

What the evidence says: Nordic hamstring curls cut hamstring injury rate by roughly half across meta-analyses. One of the best-evidenced prevention exercises that exists.

Prevalence basis: Sports injury registries

What is going on: Sudden eccentric load on the medial gastrocnemius at the musculotendinous junction, typically pushing off

Strength work: Legs: Calves: Gastrocnemius; Legs: Calves: Soleus - progressive from double-leg to single-leg to spring loading

Stretching: Legs: Calves; Legs: Calves: Gastrocnemius; Legs: Calves: Soleus - gently, not in the first days

Massage: Legs: Calves; Massage Stick - not over an acute tear

Also worth doing: Gradual return to running; heel lift early

Get it checked if: A hot swollen painful calf could be a DVT rather than a strain, especially without a clear injury moment - do NOT massage, get it assessed

What the evidence says: Progressive calf loading through full range prevents recurrence. Returning to sprinting too early is the main cause of re-tear.

Prevalence basis: Sports injury data

What is going on: Eccentric overload of rectus femoris, or direct impact causing a contusion

Strength work: Legs: Quads; Legs: Quads: Rectus Femoris; Glutes: Max

Stretching: Legs: Quads; Hips: Flexors - gently after the acute phase

Massage: Legs: Quads - never on an acute contusion; deep massage on a fresh contusion risks myositis ossificans

Also worth doing: Progressive loading; early gentle range of motion beats immobilization

Get it checked if: A rapidly swelling, very firm and extremely painful thigh could be compartment syndrome - emergency. Never deep-massage a fresh contusion

What the evidence says: Progressive loading with early controlled range. The one hard rule is no deep massage on a fresh contusion - it can cause bone to form in the muscle.

Prevalence basis: Sports injury surveillance

What is going on: Adductor longus overload at the pubic attachment; adductor weakness relative to abductors is the risk factor

Strength work: Hips: Adductors - the Copenhagen adduction exercise is the key one; Glutes: Med; Core: Transverse Abdominis

Stretching: Hips: Adductors; Hips: Flexors

Massage: Hips: Adductors

Also worth doing: Progressive return to sprinting and cutting

Get it checked if: Groin pain with a lump, or pain radiating to the testicle, needs a hernia assessment

What the evidence says: The Copenhagen adduction program cut groin injury rate by 41% in a large cluster RCT. Adding this one exercise would be high value.

Prevalence basis: Sports injury data

What is going on: Sustained low-level tension in forearm and intrinsic hand muscles with the wrist held at end range

Strength work: Arms: Forearms: Wrist Extensors; Wrist Flexors; Arms: Forearms: Pronators and Supinators; Hands, Fingers, Forearms, Grip

Stretching: Hands, Fingers, Wrists

Massage: Arms: Forearms; Hands, Fingers

Also worth doing: Neutral wrist setup; vertical mouse; microbreaks

Get it checked if: Night numbness suggests carpal tunnel; swelling and locking suggests tenosynovitis

What the evidence says: Exercise and microbreaks reduce symptoms in office workers. Workstation change alone does less than most people expect.

Prevalence basis: Occupational health surveys

What is going on: A defect in the abdominal wall through which tissue protrudes. It is a structural hole. No amount of core training closes it, and the common belief that strong abs prevent it is not supported

Strength work: Core training does NOT close or prevent a hernia. After surgical repair, graded return to loading is appropriate and safe from about 2-4 weeks as cleared

Stretching: Not relevant

Massage: Never massage a hernia

Also worth doing: Surgical repair is the only treatment. Watchful waiting is reasonable for a small painless one

Get it checked if: A hernia that becomes hard, painful, red, or cannot be pushed back in may be strangulated - SURGICAL EMERGENCY, go to hospital

What the evidence says: Included as a corrective entry. People blame lifting and try to fix hernias with core work; neither belief holds up. The useful routine is the graded return AFTER repair, and returning to lifting early does not increase recurrence.

Prevalence basis: Surgical epidemiology

What is going on: Triangular fibrocartilage complex load or tear on the ulnar side; aggravated by gripping with the wrist deviated

Strength work: Arms: Forearms: Pronators and Supinators; Arms: Forearms: Wrist Flexors and Extensors; Hands, Fingers, Forearms, Grip - focus on the deep stabilizers (ECU and pronator quadratus)

Stretching: Hands, Fingers, Wrists - gently, avoid end-range ulnar deviation

Massage: Arms: Forearms

Also worth doing: Wrist widget or brace; avoid push-up positions on an extended wrist while healing - use fists or handles

Get it checked if: A click with pain and instability, or wrist pain after a fall onto an outstretched hand, needs imaging - scaphoid fractures are missed constantly

What the evidence says: Deep stabilizer strengthening plus load modification resolves most non-traumatic cases. Traumatic tears with instability often need surgical assessment.

Prevalence basis: Hand surgery series

What is going on: Tenosynovitis of abductor pollicis longus and extensor pollicis brevis in the first dorsal compartment; lifting a baby with abducted thumbs is the classic cause

Strength work: Arms: Forearms: Wrist Extensors; Hands, Fingers, Forearms, Grip - eccentric thumb and wrist work once irritability settles

Stretching: Hands, Fingers, Wrists

Massage: Arms: Forearms; Hands, Fingers

Also worth doing: Thumb spica splint; change lifting technique - scoop under, do not pinch

Get it checked if: Severe pain with swelling and redness needs review to exclude infection

What the evidence says: Splinting plus activity modification is first-line; eccentric loading helps in the subacute phase. Very high yield in new parents.

Prevalence basis: Hand surgery epidemiology

What is going on: A1 pulley thickening catches the flexor tendon nodule

Strength work: Hands, Fingers, Forearms, Grip - gentle, avoid heavy sustained gripping while irritable

Stretching: Hands, Fingers, Wrists

Massage: Hands, Fingers - palmar and A1 pulley area

Also worth doing: Tendon gliding exercises; night splint in extension

Get it checked if: A finger locked in flexion that cannot be passively straightened needs a hand surgeon

What the evidence says: Splinting and tendon gliding resolve many early cases. Injection is the usual next step - exercise is an adjunct.

Prevalence basis: Hand surgery epidemiology

What is going on: Degenerative tendinopathy of the common flexor origin

Strength work: Arms: Forearms: Wrist Flexors - slow eccentric wrist flexion; Hands, Fingers, Forearms, Grip; Back: Lats for the kinetic chain

Stretching: Hands, Fingers, Wrists - wrist extension stretch with the elbow straight

Massage: Arms: Forearms

Also worth doing: Grip modification; counterforce brace

Get it checked if: Numbness in the ring and little finger means ulnar nerve involvement - different problem

What the evidence says: Same principles as tennis elbow: progressive eccentric or heavy-slow loading of the wrist flexors.

Prevalence basis: Elbow disorder epidemiology

What is going on: Capsulolabral damage after dislocation, or generalized laxity; the cuff and scapular muscles must compensate for lost passive restraint

Strength work: Shoulders: Rotator Cuff; Subscapularis; Infraspinatus & Teres Minor; Shoulders: Serratus Anterior; Back: Traps: Lower - closed-chain and rhythmic stabilization work

Stretching: AVOID stretching into the apprehension position (abduction with external rotation); Back: Lats instead

Massage: Back: Upper Back

Also worth doing: Proprioceptive and perturbation training; avoid overhead throwing until controlled

Get it checked if: A first dislocation in someone under 25 has a very high recurrence rate and deserves early surgical discussion; numbness or a cold arm after dislocation is urgent

What the evidence says: Structured rehabilitation reduces recurrence in atraumatic and older-patient instability. In young athletes after a traumatic dislocation, surgery outperforms rehab for recurrence - be honest about that.

Prevalence basis: Shoulder trauma epidemiology

What is going on: Ulnar nerve compressed or stretched behind the medial elbow, worsened by prolonged elbow flexion (phone, sleeping) and leaning on the elbow

Strength work: Hands, Fingers, Forearms, Grip; Arms: Forearms: Wrist Flexors; Back: Traps: Lower for the postural chain

Stretching: Hands, Fingers, Wrists

Massage: Arms: Forearms - avoid direct pressure on the nerve groove

Also worth doing: Night elbow extension splint or a towel wrap; stop leaning on the elbow; ulnar nerve glides

Get it checked if: Wasting between the thumb and index finger, or a claw posture of the ring and little fingers, means advanced compression - surgical referral, do not delay

What the evidence says: Activity modification and night splinting resolve most mild cases. Nerve gliding is a reasonable adjunct. Established muscle wasting does not recover with exercise.

Prevalence basis: Nerve conduction population studies

What is going on: Degenerative change in the patellar tendon from repeated high-rate loading

Strength work: Legs: Quads - heavy slow resistance squats and leg press; isometric holds (Spanish squat) for pain relief; Glutes: Max

Stretching: Legs: Quads; Legs: Hamstrings; Legs: Calves

Massage: Legs: Quads

Also worth doing: Load management; isometrics before activity for analgesia

Get it checked if: Pain in an adolescent at the tibial tubercle is Osgood-Schlatter instead

What the evidence says: Heavy slow resistance beats eccentric-only and beats injection at 12 months. Isometric holds give 45 min of analgesia - useful before sport.

Prevalence basis: Sports medicine prevalence

What is going on: Degenerative change in the quadriceps tendon at the upper patellar pole from repeated high-load knee extension

Strength work: Legs: Quads - heavy slow resistance; isometric holds for pain relief; Glutes: Max

Stretching: Legs: Quads; Hips: Flexors; Legs: Calves

Massage: Legs: Quads

Also worth doing: Reduce deep squat volume while irritable; isometrics before training for analgesia

Get it checked if: Sudden inability to straighten the knee after a pop - possible tendon rupture, urgent

What the evidence says: Same loading principles as patellar tendinopathy: heavy slow resistance, isometrics for analgesia, patience measured in months not weeks.

Prevalence basis: Sports medicine series

What is going on: Rapid cervical acceleration-deceleration; most tissue heals but pain persists in a third, driven by fear and disuse

Strength work: Neck; Neck: Splenius; Neck: SCM; Back: Traps: Lower - start early and gently; Neck: Deep Neck Flexors

Stretching: Neck; Shoulders

Massage: Neck & Shoulders; Neck: SCM

Also worth doing: Return to normal activity early - collars and rest worsen outcomes

Get it checked if: Severe midline tenderness, neurological signs, or altered consciousness after trauma - image before any exercise

What the evidence says: Act-as-usual with early movement beats immobilization. Specific neck exercise helps the chronic group.

Prevalence basis: Injury surveillance

What is going on: Sudden painful restriction, often on waking, from a facet joint or muscle spasm; self-limiting over days

Strength work: Neck - gentle isometrics in a pain-free position; Back: Traps: Lower; Neck: Deep Neck Flexors

Stretching: Neck - gentle active range within tolerance, never forced

Massage: Neck & Shoulders; Neck: SCM; Back: Upper Back

Also worth doing: Keep moving within comfort; heat; avoid a collar

Get it checked if: Wry neck after trauma, with fever, or with neurological signs needs assessment before any movement therapy

What the evidence says: Gentle early movement plus reassurance resolves most episodes in a week. Rest and collars prolong it.

Prevalence basis: Primary-care presentation data

What is going on: Compression of the brachial plexus or subclavian vessels between scalenes, first rib and pectoralis minor

Strength work: Back: Traps: Lower; Back: Rhomboids; Shoulders: Serratus Anterior; Neck

Stretching: Chest - pectoralis minor; Neck - scalenes; Back: Lats

Massage: Neck & Shoulders; Chest; scalene and pec minor release

Also worth doing: Avoid overhead and heavy-bag carrying; nerve glides

Get it checked if: Arm swelling, discoloration, or coolness suggests vascular TOS - urgent vascular referral, this is not a stretching problem

What the evidence says: Postural and scapular strengthening plus first-rib and pec minor mobilization helps neurogenic TOS. Vascular TOS is a surgical problem - screen for it.

Prevalence basis: Vascular and neurosurgical series

What is going on: Age-related tendon degeneration; symptoms depend far more on cuff and scapular function than on tear size

Strength work: Shoulders: Rotator Cuff; Infraspinatus & Teres Minor; Subscapularis; Back: Traps: Lower; Shoulders: Serratus Anterior

Stretching: Shoulders; Chest; posterior capsule

Massage: Shoulders: Rotator Cuff; Back: Upper Back

Also worth doing: Avoid painful overhead ranges while building

Get it checked if: Acute traumatic tear in a younger person with sudden weakness - surgical referral within weeks; a dropped arm sign needs urgent review

What the evidence says: Exercise is first-line for atraumatic degenerative tears; most people get good function without repair. Traumatic tears in the under-60s are the exception.

Prevalence basis: Shoulder imaging cohorts

What is going on: Long head of biceps tendon irritation in the bicipital groove, usually secondary to cuff or labral problems rather than primary

Strength work: Shoulders: Rotator Cuff; Arms: Biceps: Long Head; Back: Traps: Lower; Shoulders: Serratus Anterior

Stretching: Chest; Shoulders; Arms: Biceps

Massage: Back: Upper Back; Chest

Also worth doing: Reduce overhead and heavy curling volume while irritable

Get it checked if: A sudden pop with a Popeye bulge in the upper arm is a biceps rupture - usually manageable without surgery but needs assessment

What the evidence says: Treat the shoulder as a whole, not the biceps in isolation - isolated biceps tendinopathy is rare and treating it alone usually fails.

Prevalence basis: Shoulder clinic series

What is going on: Degeneration or past separation of the acromioclavicular joint; aggravated by cross-body reaching and heavy pressing

Strength work: Back: Traps: Lower and Middle; Shoulders: Serratus Anterior; Shoulders: Rotator Cuff

Stretching: AVOID the cross-body adduction stretch while irritable - it loads the joint; Chest instead

Massage: Back: Upper Back; Neck & Shoulders

Also worth doing: Reduce bench pressing and dips; narrow grip changes

Get it checked if: A step deformity after a fall onto the shoulder is an AC separation - assess before loading

What the evidence says: Scapular strengthening plus load modification. The classic cross-body stretch compresses this joint - another case where the intuitive stretch is the wrong one.

Prevalence basis: Shoulder imaging cohorts

What is going on: Bony morphology plus deep flexion loading irritates the labrum and cartilage; deep hip flexors and rotators compensate

Strength work: Glutes: Max; Glutes: Med; Hips: Deep External Rotators; Core: Transverse Abdominis

Stretching: AVOID forcing deep flexion and end-range internal rotation; Hips: Flexors; Glutes: Piriformis gently

Massage: Hips: Psoas; Hips: TFL; Glutes

Also worth doing: Modify squat depth; avoid prolonged deep sitting

Get it checked if: Groin pain with locking or giving way; night pain; a limp in a young person

What the evidence says: Physiotherapy-led exercise and arthroscopy give similar 12-month outcomes in several trials. Start with exercise.

Prevalence basis: Hip imaging cohorts

What is going on: Coccygeal irritation after a fall or childbirth, often with pelvic floor hypertonicity

Strength work: Core: Pelvic Floor - down-training, not strengthening; Glutes: Max

Stretching: Glutes: Piriformis; Hips: Flexors; Back: Lower Back

Massage: Glutes; pelvic floor release work

Also worth doing: Wedge or donut cushion; avoid prolonged sitting

Get it checked if: Pain after a fall in someone with osteoporosis; night pain; bowel changes

What the evidence says: Cushioning plus pelvic floor down-training helps most. Strengthening a hypertonic pelvic floor makes this worse - the direction matters.

Prevalence basis: Spine clinic series

What is going on: Pelvic floor muscle hypertonicity and central sensitization; usually not an infection despite the name

Strength work: Core: Pelvic Floor - relaxation and down-training first, strengthening only later; Glutes: Max

Stretching: Hips: Adductors; Hips: Flexors; Glutes: Piriformis

Massage: Glutes; internal and external pelvic floor release (specialist)

Also worth doing: Stress management; avoid prolonged sitting and cycling while flaring

Get it checked if: Fever, blood in urine, or acute retention needs urgent urology

What the evidence says: Pelvic floor physical therapy is the best-supported treatment. Kegels make this WORSE - it is the opposite of incontinence. Flag that prominently.

Prevalence basis: Urology epidemiology

What is going on: Sphincter and pelvic floor function disrupted by surgery

Strength work: Core: Pelvic Floor - start before surgery (prehabilitation) and resume immediately after

Stretching: Not primary

Massage: Not primary

Also worth doing: Fluid and bladder management

Get it checked if: New pain, fever or retention after surgery needs urgent review

What the evidence says: Pelvic floor training started before surgery shortens time to continence. Best results come from supervised training with feedback.

Prevalence basis: Urology outcome data

What is going on: Inflammation or mechanical irritation of the costochondral junctions, often after coughing, lifting or a new push workout

Strength work: Back: Traps: Lower; Back: Rhomboids - once cardiac causes are excluded

Stretching: Chest; Trunk; Spine - thoracic rotation

Massage: Chest; Back: Upper Back; intercostal work

Also worth doing: Reduce heavy pressing while symptomatic

Get it checked if: CHEST PAIN MUST HAVE CARDIAC AND PULMONARY CAUSES EXCLUDED FIRST. Crushing pain, breathlessness, sweating, radiation to the jaw or arm - emergency

What the evidence says: Self-limiting in most cases. Stretching and manual therapy help. The safety gate matters more than the routine here.

Prevalence basis: Emergency department chest pain series

What is going on: Iliopsoas tendon snapping over the pelvic brim (internal) or IT band over the trochanter (external)

Strength work: Glutes: Med; Core: Transverse Abdominis; Hips: Deep External Rotators

Stretching: Hips: Flexors; Hips: IT Band; Glutes

Massage: Hips: Psoas; Hips: TFL; Hips: IT Band

Also worth doing: Reduce repetitive hip flexion volume while irritable

Get it checked if: Painless snapping needs no treatment at all; painful snapping with catching may indicate a labral tear

What the evidence says: Painless clicking is benign - say so. When painful, hip flexor and abductor strengthening plus load reduction resolves most cases.

Prevalence basis: Sports medicine series

What is going on: Iliopsoas overload, often in a muscle already held short by sitting and never loaded through range

Strength work: Hips: Flexors; Hips: Flexors: Psoas; Hips: Flexors: Iliacus; Glutes: Max - loaded hip flexion through range, not just stretching

Stretching: Hips: Flexors; Legs: Quads

Massage: Hips: Psoas; Hips: Iliacus; Hips: TFL

Also worth doing: Reduce sprinting and high-knee volume while irritable

Get it checked if: Groin pain with a limp in an adolescent, or after a fall in an older adult, needs imaging

What the evidence says: Stretching alone usually fails here. A short hip flexor that hurts needs loading through range, not more stretching.

Prevalence basis: Sports medicine series

What is going on: Bone lengthens faster than muscle and tendon adapt, so the muscle is functionally short for a period. Hamstrings, quads and calves are worst affected, which is why Osgood-Schlatter and Sever's cluster in the same window

Strength work: Legs: Quads; Legs: Hamstrings; Legs: Calves; Glutes: Max - light and consistent, alongside sport rather than instead of it

Stretching: Legs: Hamstrings; Legs: Quads; Legs: Calves; Hips: Flexors - daily, short sessions

Massage: Legs: Quads; Legs: Hamstrings; Legs: Calves

Also worth doing: Manage sport volume through the growth spurt; a single-sport year-round schedule is the risk factor

Get it checked if: One-sided pain, night pain, a limp, or joint swelling is not growth-related - refer

What the evidence says: Daily short stretching through the growth spurt reduces the apophysitis conditions that cluster in this window. The volume management matters at least as much.

Prevalence basis: Pediatric sports medicine literature

What is going on: Three-dimensional spinal deformity; asymmetric muscle activity follows rather than causes it

Strength work: Back: Spinal Erectors; Core: Transverse Abdominis; Abs: Obliques; asymmetric side-specific work

Stretching: Back: Lats; Hips: Flexors; Legs: Hamstrings

Massage: Back: QL; Back: Upper Back

Also worth doing: Schroth or PSSE method requires a trained instructor; bracing for growing adolescents

Get it checked if: A rapidly progressing curve during a growth spurt needs orthopedic review; a new curve in an adult with pain needs imaging

What the evidence says: Scoliosis-specific exercise (Schroth/PSSE) reduces curve progression modestly. General strengthening improves function and pain but not the curve. Be honest about which is which.

Prevalence basis: School screening data

What is going on: Excessive connective-tissue laxity means joints reach end range without ligamentous protection; muscles must do the job instead

Strength work: Full Body; Glutes: Med; Core: Transverse Abdominis; Shoulders: Rotator Cuff; slow controlled work through MID range

Stretching: MINIMIZE stretching - it makes hypermobility worse; mobility work only where genuinely stiff

Massage: Light only; deep work can increase laxity symptoms

Also worth doing: Proprioception and balance training; avoid end-range positions and hanging on ligaments

Get it checked if: Frequent subluxations, dislocations, or fainting on standing (dysautonomia) needs specialist review

What the evidence says: THE KEY INVERSION ON THIS LIST: hypermobile people feel stiff and stretch more, which worsens the problem. They need strength and proprioception, not flexibility. Any general stretch routine should carry a hypermobility warning.

Prevalence basis: Beighton score population studies

What is going on: Serratus anterior weakness (or long thoracic nerve injury) lets the medial scapular border lift off the ribcage

Strength work: Shoulders: Serratus Anterior - push-up plus, wall slides, overhead press progressions; Back: Traps: Lower

Stretching: Chest; Back: Lats

Massage: Back: Upper Back; Chest

Also worth doing: Avoid heavy overhead work until the scapula controls

Get it checked if: Sudden winging after trauma or a viral illness suggests nerve palsy - refer, recovery takes 12-24 months

What the evidence says: Serratus strengthening improves scapular control and shoulder pain. The library needs more than one exercise here.

Prevalence basis: Clinical examination series

What is going on: Perineural fibrosis of an interdigital nerve, usually between the third and fourth toes, compressed by narrow shoes

Strength work: Feet, Toes, Ankles; Toe Neuromuscular Exercises; intrinsic foot work; Feet, Toes, Ankles: Intrinsic Foot Muscles

Stretching: Feet, Toes, Ankles; toe splaying

Massage: Feet, Toes, Ankles; Massage Ball - avoid direct pressure on the neuroma itself

Also worth doing: Wide toe-box shoes; metatarsal pad; Wear Toe Spacers

Get it checked if: Progressive numbness or weakness; burning in both feet suggests neuropathy instead

What the evidence says: Footwear change and metatarsal padding do most of the work. Foot strengthening and spacers help. Do not press directly on the neuroma.

Prevalence basis: Foot and ankle series

What is going on: Overload of the peroneal tendons behind the outer ankle, usually in an ankle that is already unstable

Strength work: Legs: Calves: Peroneals - resisted eversion; Feet, Toes, Ankles; Glutes: Med

Stretching: Legs: Calves; Feet, Toes, Ankles

Massage: Legs: Calves: Peroneals (Fibularis); Legs: Calves: Peroneals

Also worth doing: Balance training; lateral support footwear; address the underlying instability

Get it checked if: Snapping over the outer ankle with pain suggests tendon subluxation; inability to weight-bear after a sprain needs fracture assessment

What the evidence says: Eccentric eversion loading plus balance work. Treating the tendon without treating the instability behind it means it comes back.

Prevalence basis: Foot and ankle series

What is going on: Tibial nerve compressed behind the inner ankle, often with a collapsing arch increasing the traction on it

Strength work: Legs: Calves: Tibialis Posterior; Feet, Toes, Ankles - support the arch to reduce nerve traction; Feet, Toes, Ankles: Intrinsic Foot Muscles

Stretching: Legs: Calves; Feet, Toes, Ankles

Massage: Feet, Toes, Ankles - avoid direct pressure over the tunnel

Also worth doing: Arch support; tibial nerve glides; night pain is characteristic

Get it checked if: Progressive numbness or weakness, or burning in both feet, suggests peripheral neuropathy rather than entrapment

What the evidence says: Arch support to reduce nerve traction plus nerve gliding. Frequently misdiagnosed as plantar fasciitis for years - the distinguishing feature is burning and night pain.

Prevalence basis: Foot and ankle series

What is going on: Degenerative arthritis of the first MTP joint limiting the dorsiflexion needed for push-off

Strength work: Feet, Toes, Ankles; Legs: Calves: Soleus; Glutes: Max to reduce compensation; Feet, Toes, Ankles: Intrinsic Foot Muscles

Stretching: Feet, Toes, Ankles; big toe extension mobilization; Legs: Calves

Massage: Feet, Toes, Ankles

Also worth doing: Rocker-sole or stiff-soled shoes; carbon plate insole

Get it checked if: Sudden hot swollen big toe joint is gout until proven otherwise

What the evidence says: Mobilization and calf work help early stages. Advanced rigidus is a footwear and surgical problem - exercise will not restore the joint.

Prevalence basis: Foot and ankle epidemiology

What is going on: Traction apophysitis at the tibial tubercle during rapid growth, with quadriceps tightness and high jumping load

Strength work: Legs: Quads - isometric and heavy slow resistance; Glutes: Max; Legs: Hamstrings

Stretching: Legs: Quads; Legs: Hamstrings; Legs: Calves

Massage: Legs: Quads

Also worth doing: Load management, not rest; the bump is permanent but the pain is not

Get it checked if: Night pain, systemic symptoms, or a limp that persists needs imaging - bone tumors present this way in this age group

What the evidence says: Load management plus progressive quadriceps loading. Complete rest delays recovery. The prominent bump remains permanently and that is fine.

Prevalence basis: Pediatric sports medicine data

What is going on: Poorly understood; likely a lower pain threshold with activity-related muscular fatigue. Not related to growth rate despite the name

Strength work: Not primary at this age

Stretching: Legs: Calves; Legs: Hamstrings; Legs: Quads - a nightly routine has trial support

Massage: Legs: Calves; Legs: Quads; Legs: Hamstrings - parental massage before bed

Also worth doing: Reassurance; heat; the pains are always bilateral and never present in the morning

Get it checked if: One-sided pain, limp, joint swelling, fever, or pain still present in the morning is NOT growing pains - refer

What the evidence says: A nightly stretching program reduced episode frequency in a controlled trial. Massage and reassurance help. The condition is benign and self-limiting.

Prevalence basis: Pediatric epidemiology

What is going on: Traction apophysitis at the calcaneal growth plate; tight calves plus growth plus impact

Strength work: Legs: Calves: Gastrocnemius; Legs: Calves: Soleus; Feet, Toes, Ankles; Feet, Toes, Ankles: Intrinsic Foot Muscles

Stretching: Legs: Calves; Legs: Calves: Gastrocnemius; Legs: Calves: Soleus; Feet, Toes, Ankles: Plantar Fascia stretch

Massage: Legs: Calves; Feet, Toes, Ankles; Feet, Toes, Ankles: Plantar Fascia massage

Also worth doing: Heel cups; load management; supportive shoes

Get it checked if: Pain at rest, night pain, or swelling needs imaging

What the evidence says: Self-limiting once the growth plate closes. Calf stretching and heel cups shorten the symptomatic period.

Prevalence basis: Pediatric sports medicine data

What is going on: Shortening or tightness of one sternocleidomastoid, so the baby prefers to look one way and rests the head on the same spot

Strength work: Strengthening the opposite side through positioning and play - encouraging the baby to turn toward the non-preferred side

Stretching: Gentle sustained SCM stretching taught and supervised by a pediatric physiotherapist. NOT a parent-improvised technique

Massage: Very light SCM work as taught by the therapist

Also worth doing: Tummy time; alternating feeding sides; repositioning toys and the crib so the interesting side is the non-preferred side

Get it checked if: A head tilt that appears after 6 months, or comes with eye movement problems or a neck lump, needs pediatric review before any stretching

What the evidence says: Early physiotherapy resolves the large majority of cases, and outcomes are much better before 6 months. Included because parents search for this constantly - but the routine must point to a clinician, not replace one.

Prevalence basis: Pediatric physiotherapy studies

What is going on: Hours of sustained neck flexion during a period of rapid growth

Strength work: Neck; Back: Traps: Lower; Back: Rhomboids; Neck: Deep Neck Flexors

Stretching: Neck; Chest; Back: Mid-Back

Massage: Neck & Shoulders

Also worth doing: Phone at eye level; screen-time limits; sport participation

Get it checked if: Persistent night pain, weight loss, or neurological signs in an adolescent always need review

What the evidence says: Same mechanism and the same fix as adults, but habit formation matters more at this age. Prevention is far easier than treatment.

Prevalence basis: Adolescent health surveys

What is going on: Repetitive valgus stress on an immature growth plate at the medial elbow or proximal humerus; pitch volume is the dominant risk factor

Strength work: Shoulders: Rotator Cuff; Back: Traps: Lower; Shoulders: Serratus Anterior; Glutes: Max; Core: Transverse Abdominis - the legs and trunk generate the throw

Stretching: Shoulders; posterior capsule (sleeper stretch); Chest

Massage: Back: Upper Back; Arms: Forearms

Also worth doing: PITCH COUNT LIMITS AND OFF-SEASON REST are the actual intervention; mechanics coaching

Get it checked if: Persistent elbow pain in a skeletally immature thrower needs imaging - growth plate injuries can end throwing careers if pushed through

What the evidence says: No exercise program offsets excessive pitch volume. Load limits plus posterior cuff and trunk strength. Year-round single-sport play is the strongest risk factor.

Prevalence basis: Youth sports medicine surveillance

What is going on: A stronger, better-conditioned neck reduces the head acceleration produced by a given impact; smaller athletes with weaker necks show higher head accelerations

Strength work: Neck; Neck: Splenius; Neck: SCM; Back: Traps: Upper, Middle and Lower; isometric and controlled multi-directional neck work; Neck: Deep Neck Flexors

Stretching: Neck - mobility, not aggressive stretching

Massage: Neck & Shoulders

Also worth doing: Technique coaching matters at least as much; this reduces risk, it does not remove it

Get it checked if: Any suspected concussion means immediate removal from play and assessment - no neck program changes that rule

What the evidence says: Neck strength is associated with lower head acceleration and lower concussion odds in observational work. The evidence is suggestive rather than settled - present it as risk reduction, never as protection.

Prevalence basis: Sports concussion surveillance

What is going on: Nerve root compression from disc herniation or foraminal narrowing, with arm pain in a dermatomal pattern

Strength work: Neck - deep cervical flexor endurance; Back: Traps: Lower; Back: Rhomboids - once acute pain settles; Neck: Deep Neck Flexors

Stretching: Neck gently; Chest

Massage: Neck & Shoulders; Back: Upper Back

Also worth doing: Nerve glides; cervical traction has moderate evidence; avoid end-range extension and rotation

Get it checked if: Progressive weakness, clumsy hands, unsteady walking, or bowel and bladder change means cord compression (myelopathy) - urgent surgical referral

What the evidence says: Most resolve within 4-6 months with conservative care. Exercise plus traction beats exercise alone in some trials.

Prevalence basis: Population incidence studies

What is going on: Nuclear material displaced against a nerve root; the vast majority resorb over months without surgery

Strength work: Core: Transverse Abdominis; Back: Spinal Erectors; Glutes: Max - build progressively

Stretching: Directional preference matters - most prefer extension (McKenzie press-up); avoid loaded flexion early

Massage: Back: QL; Glutes

Also worth doing: Walking; avoid prolonged sitting; nerve glides

Get it checked if: Cauda equina signs (saddle numbness, bowel or bladder change, bilateral leg weakness) = EMERGENCY; progressive foot drop needs urgent review

What the evidence says: Natural history is favorable - most resorb. Exercise reduces recurrence more than it speeds resolution. Match direction to what centralizes the leg pain.

Prevalence basis: Imaging and clinical cohorts

What is going on: A stress fracture of the pars interarticularis, from repeated extension and rotation - gymnastics, cricket, diving, dance

Strength work: Core: Transverse Abdominis; Abs: Obliques; Glutes: Max - anti-extension and anti-rotation emphasis

Stretching: Flexion-biased; Hips: Flexors; Legs: Hamstrings - hamstrings are classically tight here; AVOID repeated extension

Massage: Back: QL; Glutes; Legs: Hamstrings

Also worth doing: Rest from the provoking extension sport; bracing in adolescents

Get it checked if: Back pain in an adolescent athlete that is worse with extension needs imaging - this is the diagnosis that gets missed and turns into a permanent slip

What the evidence says: Deep core and gluteal strengthening with extension avoidance. In adolescents, early diagnosis and relative rest allow the fracture to heal; late diagnosis does not.

Prevalence basis: Spine imaging cohorts

What is going on: Age-related disc dehydration and height loss. It is a normal finding as often as it is a diagnosis - the imaging correlates poorly with pain

Strength work: Core: Transverse Abdominis; Back: Spinal Erectors; Glutes: Max; build load tolerance

Stretching: Hips: Flexors; Legs: Hamstrings; Spine

Massage: Back: QL; Glutes

Also worth doing: Walking; varied movement; avoiding the belief that the spine is fragile

Get it checked if: Same as low back pain red flags

What the evidence says: IMPORTANT FRAMING: the words on the scan report frighten people into inactivity, and the fear predicts disability better than the imaging does. This entry exists mainly to be reassuring.

Prevalence basis: Asymptomatic imaging studies

What is going on: A week of sustained eccentric quadriceps work and unfamiliar balance demands, attempted on legs that have done nothing since last winter. Fatigue late in the day is when most injuries happen

Strength work: Legs: Quads - eccentric and isometric wall sits; Glutes: Med; Glutes: Max; Core: Transverse Abdominis; Legs: Hamstrings for knee protection; Hands, Fingers, Forearms, Grip and Arms: Forearms: Wrist Extensors for snowboarders

Stretching: Legs: Quads; Hips: Flexors; Legs: Calves; Back: Lower Back

Massage: Legs: Quads; Legs: Calves; Back: Quadratus Lumborum (QL)

Also worth doing: Start six weeks out; balance and single-leg work; stop skiing when the legs are done rather than at the last lift

Get it checked if: Any previous knee ligament injury deserves specific preparation and possibly a brace - get advice before the trip

What the evidence says: Eccentric quad and hip strength plus balance is the specific preparation, and pre-season conditioning demonstrably reduces winter sport injury rates. Seasonal, so it needs to be prompted at the right time of year to be used.

Prevalence basis: Winter sports injury surveillance

What is going on: Degenerative facet joints, aggravated by extension and rotation

Strength work: Core: Transverse Abdominis; Glutes: Max; Abs: Obliques - anti-extension emphasis

Stretching: Flexion bias helps - knees to chest; Hips: Flexors; AVOID repeated extension

Massage: Back: QL; Back: Lower Back area; Glutes

Also worth doing: Reduce standing extension postures

Get it checked if: Same red flags as low back pain; inflammatory pattern in a young adult - screen for axial spondyloarthritis

What the evidence says: Direction is the key distinction from disc pain: facets dislike extension, discs often dislike flexion. The same generic back routine will help one and aggravate the other.

Prevalence basis: Diagnostic block studies

What is going on: Bone remodeling cannot keep pace with repeated load, often with low energy availability or low bone density

Strength work: Full Body; Legs: Quads; Glutes; heavy resistance work builds bone tolerance

Stretching: Not primary

Massage: Not primary

Also worth doing: Load progression under 10% per week; adequate energy and calcium intake

Get it checked if: Focal bone tenderness with pain that worsens through activity and hurts at rest - stop loading and image; missed periods plus stress fractures means low energy availability, needs medical review

What the evidence says: Resistance training builds bone that running does not. Runners who lift get fewer bone stress injuries.

Prevalence basis: Sports medicine surveillance

What is going on: Most likely irritation of the parietal peritoneum, aggravated by a full stomach, dehydration and shallow rapid breathing

Strength work: Core: Transverse Abdominis; Core: Diaphragm - trunk endurance is associated with fewer episodes

Stretching: Trunk; Spine - side flexion and rotation before running

Massage: Not primary

Also worth doing: Avoid large meals and hypertonic drinks within 2 hours; deeper controlled breathing; pressure with the hand plus a forced exhale on the affected side often breaks it mid-run

Get it checked if: Abdominal pain that persists after stopping, or comes with vomiting or fever, is not a stitch

What the evidence says: Benign and self-limiting. Trunk conditioning and meal timing reduce frequency. Worth including because it is common, easily fixed, and constantly asked about.

Prevalence basis: Sports medicine surveys

What is going on: Insufficient energy intake for training load, suppressing hormones, bone density, immunity and recovery. More training makes it worse, not better

Strength work: MORE EXERCISE IS THE WRONG PRESCRIPTION. Resistance training only once energy intake is corrected

Stretching: Not the issue

Massage: Not the issue

Also worth doing: Increase energy intake; reduce training volume; medical and dietetic support

Get it checked if: Missed or lost periods, repeated stress fractures, persistent fatigue and frequent illness in someone training hard is RED-S until proven otherwise - refer

What the evidence says: A negative entry by design. A fitness app that only encourages more training is actively dangerous to this group. Missed periods plus a stress fracture should trigger a caution, not a new program.

Prevalence basis: Sports medicine screening studies

What is going on: Muscle swelling inside a non-compliant fascial compartment raises pressure during exercise; symptoms resolve within minutes of stopping

Strength work: Legs: Calves: Tibialis Anterior; Legs: Calves: Soleus - build tolerance gradually

Stretching: Legs: Calves; Feet, Toes, Ankles

Massage: Legs: Calves: Tibialis Anterior; Legs: Calves; Foam Roller Massage

Also worth doing: Gait retraining to a forefoot strike has trial support; volume reduction; surgery (fasciotomy) for resistant cases

Get it checked if: Pain that does NOT resolve with rest, or numbness that persists, is acute compartment syndrome - a surgical emergency

What the evidence says: Gait retraining helps a meaningful proportion. Conservative treatment often fails and fasciotomy is the definitive answer - do not over-promise the routine.

Prevalence basis: Sports medicine series

What is going on: Irritation of the bursa under the sartorius, gracilis and semitendinosus insertion on the medial tibia

Strength work: Glutes: Med; Legs: Quads; Hips: Adductors

Stretching: Legs: Hamstrings; Hips: Adductors; Legs: Quads

Massage: Legs: Hamstrings; Hips: Adductors

Also worth doing: Pillow between the knees at night; load management

Get it checked if: Warmth, redness and fever suggest septic bursitis - urgent

What the evidence says: Usually settles with load reduction plus hip and quad strengthening. Often coexists with knee OA - treat both.

Prevalence basis: Knee clinic series

What is going on: Cartilage loss in the ball-and-socket joint itself, distinct from the far commoner rotator cuff problems

Strength work: Shoulders: Rotator Cuff; Back: Traps: Lower; Shoulders: Serratus Anterior; Shoulders: Deltoids - work within a comfortable range

Stretching: Shoulders; Chest; Back: Lats - maintain what range you have; do not force it

Massage: Back: Upper Back; Shoulders: Rotator Cuff

Also worth doing: Load and range modification; joint replacement is very effective when conservative care runs out

Get it checked if: Night pain with fever; sudden loss of movement after trauma; a grinding shoulder that is also weak and unstable

What the evidence says: Exercise maintains function and reduces pain but does not alter the joint surface. Distinguish it from cuff-related pain, because the range expectations are different.

Prevalence basis: Shoulder epidemiology

What is going on: Joint fluid tracking into the popliteal bursa; it is a symptom of what is happening inside the knee, not a problem in itself

Strength work: Legs: Quads; Glutes: Med; Legs: Hamstrings - treat the underlying knee problem

Stretching: Legs: Hamstrings; Legs: Calves

Massage: Legs: Hamstrings; Legs: Calves - avoid direct pressure on the cyst

Also worth doing: Manage the underlying knee osteoarthritis or meniscal problem

Get it checked if: A ruptured cyst mimics a DVT exactly - sudden calf pain and swelling needs a scan before anyone massages it

What the evidence says: Treat the knee, not the cyst. Aspiration without treating the cause means it refills.

Prevalence basis: Knee imaging studies

What is going on: Compression of the ischial bursa or proximal hamstring tendon against a hard seat

Strength work: Legs: Hamstrings - isometric and long-lever progressive loading; Glutes: Max

Stretching: AVOID deep hamstring stretching - it compresses the tendon at the ischium; Glutes: Piriformis instead

Massage: Glutes; avoid direct pressure on the ischial tuberosity

Also worth doing: Cushioned seat; stand breaks; avoid sitting on hard edges

Get it checked if: Numbness in the buttock or down the leg suggests nerve involvement

What the evidence says: IMPORTANT INVERSION: proximal hamstring tendinopathy gets worse with hamstring stretching. Isometric loading in a neutral hip position is the treatment.

Prevalence basis: Clinical series

What is going on: Massive repetitive overhead volume with internal rotator dominance and scapular fatigue

Strength work: Shoulders: Rotator Cuff; Infraspinatus & Teres Minor; Back: Traps: Lower; Shoulders: Serratus Anterior; external rotation endurance

Stretching: Chest; Back: Lats; posterior capsule (sleeper stretch)

Massage: Back: Upper Back; Chest; Shoulders: Rotator Cuff

Also worth doing: Stroke technique; reduce paddle and band volume while symptomatic

Get it checked if: Night pain, weakness, or instability episodes need assessment

What the evidence says: Posterior cuff endurance and scapular control plus volume management. Stretching an already-lax swimmer's shoulder is counterproductive.

Prevalence basis: Aquatic sports medicine surveys

What is going on: Crimp-grip loading exceeds pulley tolerance; flexor tendon bowstringing in severe cases

Strength work: Hands, Fingers, Forearms, Grip; Arms: Forearms: Wrist Flexors and Extensors - balance the antagonists; progressive hangboard loading

Stretching: Hands, Fingers, Wrists

Massage: Hands, Fingers; Arms: Forearms

Also worth doing: Avoid full crimp while healing; H-taping; grade reduction

Get it checked if: An audible pop with immediate swelling and bowstringing needs imaging and possibly surgery

What the evidence says: Progressive loading rehabilitates pulley strains. Antagonist (extensor) training reduces recurrence.

Prevalence basis: Climbing medicine surveys

What is going on: Stress reaction at the pubic symphysis from imbalanced load between the adductors and the abdominal wall

Strength work: Hips: Adductors; Core: Transverse Abdominis; Abs: Obliques; Glutes: Max - restore the adductor to abdominal balance

Stretching: Hips: Adductors; Hips: Flexors - gently

Massage: Hips: Adductors

Also worth doing: Load management; gradual return to kicking and sprinting

Get it checked if: Groin pain with fever, or in a postpartum woman with severe pain on walking, needs assessment

What the evidence says: Progressive adductor and deep abdominal loading. Slow to settle - months, not weeks. Rest alone does not fix it.

Prevalence basis: Sports medicine and obstetric series

What is going on: Repetitive loading of the ribs by serratus anterior and external oblique, particularly with high training volume and low bone density

Strength work: Shoulders: Serratus Anterior; Abs: Obliques; Core: Transverse Abdominis - balanced, not volume-driven

Stretching: Trunk; Spine; Chest

Massage: Back: Upper Back; Chest; intercostal work

Also worth doing: Training volume management; ergometer volume is a specific risk factor

Get it checked if: Focal rib pain with a cough, breathlessness, or after trauma needs imaging - a rib stress fracture takes weeks off

What the evidence says: Load management is the treatment. Bone density and energy availability matter - check the under-fueling entry alongside this one.

Prevalence basis: Rowing sports medicine surveys

What is going on: Hours with the arms above shoulder height compresses the subacromial space and fatigues the cuff and scapular stabilizers, in a position the body can only hold briefly before compensating through the neck and low back

Strength work: Shoulders: Rotator Cuff; Infraspinatus & Teres Minor; Back: Traps: Lower and Middle; Shoulders: Serratus Anterior; Neck - endurance, not maximal strength, is what this job needs

Stretching: Chest; Back: Lats; Neck; Spine - thoracic extension buys shoulder range

Massage: Neck & Shoulders; Back: Upper Back; Shoulders: Rotator Cuff; Chest

Also worth doing: Rotate tasks so arms come down; use a platform or extension pole to lower the working height; micro-breaks beat one long break

Get it checked if: Night shoulder pain, weakness lifting the arm, or arm numbness needs assessment before continuing the work pattern

What the evidence says: Cuff and scapular endurance training reduces shoulder complaints in overhead workers. Lowering the working height does more than any exercise, so the routine should say that first.

Prevalence basis: Occupational health surveillance

What is going on: Repeated lifting and repositioning of an unpredictable, awkward, heavy load, often from a poor position at a bed or bath, at speed, while fatigued and frequently while short-staffed

Strength work: Glutes: Max; Core: Transverse Abdominis; Abs: Obliques; Back: Spinal Erectors; Back: Lower Back; hip hinge patterning and loaded carries - train the trunk to resist rotation, which is what actually fails

Stretching: Hips: Flexors; Legs: Hamstrings; Legs: Calves; Back: Lower Back

Massage: Back: Quadratus Lumborum (QL); Glutes; Back: Upper Back; Legs: Calves

Also worth doing: Hoists and slide sheets exist for a reason and are the actual intervention; get the bed to the right height; never twist while loaded

Get it checked if: Back pain with leg symptoms, or any injury sustained lifting a person, should be reported and assessed - not worked through

What the evidence says: Exercise programs for care staff reduce back pain and sick days; equipment and staffing reduce them more. Be honest that a routine is the part the individual controls, not the whole answer.

Prevalence basis: Occupational injury surveillance

What is going on: Explosive lateral movement and overhead serving in bodies that have not trained for either; Achilles and wrist fractures from falls dominate

Strength work: Legs: Calves: Gastrocnemius and Soleus; Glutes: Med; Legs: Quads; Shoulders: Rotator Cuff; Arms: Forearms: Wrist Extensors

Stretching: Legs: Calves; Shoulders; Hips: Flexors; Legs: Hamstrings

Massage: Legs: Calves; Shoulders area; Arms: Forearms

Also worth doing: Balance and lateral agility work; proper warm-up; court shoes not running shoes

Get it checked if: Sudden calf pop while lunging back - suspect Achilles rupture, urgent

What the evidence says: Achilles rupture and distal radius fracture are the signature injuries. Calf strengthening and balance training address both.

Prevalence basis: Emergency department injury data

What is going on: Autoimmune synovitis; muscle wasting (rheumatoid cachexia) compounds joint damage

Strength work: Full Body; Hands, Fingers, Forearms, Grip; progressive resistance training is safe and recommended

Stretching: Full Body; joint-specific ROM daily

Massage: Professional Massage; light peripheral work

Also worth doing: Pace around flares; keep moving between them

Get it checked if: Hot swollen joints with fever could be septic arthritis - urgent; new inflammatory symptoms need rheumatology, not exercise alone

What the evidence says: High-intensity resistance training is safe in stable RA and reverses cachexia. Old advice to avoid loading joints has been overturned.

Prevalence basis: Rheumatology registries

What is going on: Inflammation at entheses and sacroiliac joints leading to progressive spinal fusion if unmanaged

Strength work: Back: Spinal Erectors; Core: Transverse Abdominis; Back: Traps: Lower; extension-biased strength

Stretching: Spine; Chest; Hips: Flexors; daily spinal extension and rotation is essential

Massage: Back: Upper Back; Back: QL

Also worth doing: Chest expansion and breathing exercises; swimming

Get it checked if: Back pain in an under-45 that improves with exercise and worsens with rest, with morning stiffness over 30 minutes, needs a rheumatology referral - this is the pattern that gets missed for years

What the evidence says: Exercise is the cornerstone of management alongside medication - it is one of the few conditions where daily stretching genuinely changes long-term structural outcome.

Prevalence basis: Rheumatology epidemiology

What is going on: Dopaminergic loss producing bradykinesia, rigidity and postural instability; exercise appears neuroprotective

Strength work: Full Body; Legs: Quads; Glutes; high-intensity and large-amplitude movements

Stretching: Chest; Hips: Flexors; Spine - counter the flexed posture

Massage: Foam Roller Massage; Neck & Shoulders

Also worth doing: Balance and gait training; boxing and dance programs; cueing strategies

Get it checked if: Freezing of gait with falls needs specialist input; sudden change may be medication-related

What the evidence says: High-intensity aerobic exercise slowed motor decline in the SPARX trial. Amplitude-based training (LSVT BIG) improves function. Exercise is disease-modifying here, not just symptomatic.

Prevalence basis: Neurology epidemiology

What is going on: Demyelination causing weakness, spasticity and fatigue; heat sensitivity limits tolerance in many

Strength work: Full Body; Legs: Quads; Glutes: Med; progressive resistance training

Stretching: Hips: Adductors; Legs: Calves; daily stretching for spasticity

Massage: Legs: Calves; Foam Roller Massage

Also worth doing: Cooling strategies; balance training; pace against fatigue

Get it checked if: New or worsening neurological symptoms may be a relapse - medical review

What the evidence says: Resistance training improves strength, walking and fatigue in MS. Old advice to avoid exercise has been reversed.

Prevalence basis: Neurology epidemiology

What is going on: Upper motor neuron damage causing weakness, spasticity and loss of selective control

Strength work: Full Body adapted; Legs: Quads; Glutes; Hands, Fingers, Forearms, Grip; task-specific repetition

Stretching: Hips: Flexors; Legs: Calves; Chest - manage spasticity patterns

Massage: Affected limb massage for spasticity and edema

Also worth doing: High-repetition task practice; balance and gait; constraint-induced movement therapy

Get it checked if: Any new stroke symptom (FAST) is an emergency; shoulder subluxation on the affected side needs support not stretching

What the evidence says: High-repetition task-specific practice plus strength training improves function. Strengthening does not increase spasticity - that myth is dead.

Prevalence basis: Stroke registries

What is going on: Airflow limitation plus, crucially, peripheral muscle dysfunction that drives the disability more than the lungs do

Strength work: Legs: Quads - quadriceps strength predicts survival in COPD; Full Body; Chest

Stretching: Chest; Trunk

Massage: Back: Upper Back; Chest

Also worth doing: Inspiratory muscle training; pursed-lip breathing; pulmonary rehab

Get it checked if: Increasing breathlessness, fever or colored sputum suggests exacerbation - medical review before exercising

What the evidence says: Pulmonary rehabilitation is one of the highest-value interventions in all of medicine. Quadriceps strength is the single best predictor of outcome. Inspiratory muscle training adds benefit.

Prevalence basis: Respiratory epidemiology

What is going on: Airway hyperresponsiveness; dysfunctional breathing patterns commonly coexist and amplify symptoms

Strength work: Full Body; Chest; general fitness raises the threshold for exercise-induced symptoms

Stretching: Chest; Trunk

Massage: Back: Upper Back

Also worth doing: Breathing retraining (Papworth or Buteyko-style); warm-up before exercise; reliever before sport

Get it checked if: Rescue inhaler not working, difficulty speaking in sentences - emergency

What the evidence says: Breathing exercises improve symptoms and quality of life but not lung function. Exercise training improves fitness safely and does not worsen asthma.

Prevalence basis: Respiratory epidemiology

What is going on: Multifactorial - treatment toxicity, anemia, deconditioning, inflammation and sleep disruption

Strength work: Full Body at moderate intensity; Legs: Quads; Glutes; resistance training 2-3x/week

Stretching: Full Body; Shoulders especially after breast surgery

Massage: Professional Massage; light lymphatic-direction work if lymphedema risk

Also worth doing: Graded aerobic work; sleep and pacing

Get it checked if: New bone pain, unexplained fracture, low platelet count, or active infection changes what is safe - coordinate with the oncology team

What the evidence says: Exercise outperforms every pharmaceutical tested for cancer-related fatigue. It is the first-line recommendation in oncology guidance.

Prevalence basis: Oncology symptom studies

What is going on: Impaired lymphatic drainage; muscle contraction is a major driver of lymph flow

Strength work: Progressive resistance training of the affected limb - Back: Lats; Shoulders: Deltoids; Hands, Fingers, Forearms, Grip

Stretching: Shoulders; gentle

Massage: Manual lymphatic drainage - light, slow, toward the trunk; NOT deep tissue work or a massage gun

Also worth doing: Compression garment during exercise; skin care

Get it checked if: Sudden increase in swelling with redness, warmth or fever suggests cellulitis - urgent antibiotics, stop massage

What the evidence says: The PAL trial overturned decades of advice: slowly progressive resistance training is SAFE and reduces lymphedema flare-ups. Fear of lifting was wrong.

Prevalence basis: Oncology outcome studies

What is going on: Scar tissue, radiation fibrosis and protective guarding restricting elevation and abduction

Strength work: Shoulders: Rotator Cuff; Back: Traps: Lower; Shoulders: Serratus Anterior - once wounds are healed

Stretching: Chest; Shoulders; Back: Lats - gradual, daily

Massage: Chest; Back: Upper Back; scar mobilization once healed

Also worth doing: Start early with gentle ROM as cleared by the surgical team

Get it checked if: Do not begin before surgical clearance; new swelling suggests lymphedema or infection

What the evidence says: Early supervised ROM restores movement without increasing complications. Delayed movement leads to lasting restriction.

Prevalence basis: Oncology rehabilitation studies

What is going on: The shoulder becomes a weight-bearing joint doing thousands of propulsion cycles plus every transfer; the posterior cuff and scapular retractors are chronically outmatched

Strength work: Shoulders: Rotator Cuff; Infraspinatus & Teres Minor; Back: Traps: Lower and Middle; Back: Rhomboids; Shoulders: Serratus Anterior - posterior chain emphasis to counter the pushing pattern

Stretching: Chest; Back: Lats; Shoulders

Massage: Back: Upper Back; Chest; Shoulders: Rotator Cuff

Also worth doing: Propulsion technique - long smooth strokes; transfer technique; equipment setup

Get it checked if: Sudden weakness, night pain, or new numbness needs assessment - and shoulder loss of function is far more disabling for a wheelchair user than for an ambulatory person

What the evidence says: Posterior cuff and scapular strengthening plus technique reduces pain. Prevention matters enormously here because the shoulder is also the means of mobility.

Prevalence basis: Spinal cord injury rehabilitation research

What is going on: Asymmetric loading throws far more work onto the intact limb and the trunk; residual limb muscles waste without deliberate training, and the energy cost of walking rises sharply

Strength work: Glutes: Max; Glutes: Med; Core: Transverse Abdominis; Back: Lats; Hands, Fingers, Forearms, Grip for upper-limb prosthesis and crutch users; residual limb strengthening as prescribed

Stretching: Hips: Flexors - contracture at the residual limb is the classic preventable complication; Legs: Hamstrings

Massage: Residual limb desensitization and scar work; Back: QL; Back: Upper Back

Also worth doing: Balance training; intact-limb protection (overuse of the sound side is extremely common); prosthetic fit review

Get it checked if: Skin breakdown, new pain, or a change in prosthetic fit needs prompt review - a small sore becomes a serious problem quickly in a vascular amputee

What the evidence says: Strength and balance training improve walking capacity and reduce falls, which are far more common in this group. Preventing hip flexion contracture early is the highest-value single thing.

Prevalence basis: Limb loss epidemiology

What is going on: Collagen laid down during healing binds tissue layers that should glide, restricting movement in the region and sometimes far from it

Strength work: Region-specific strength once healed - progressive loading remodels scar tissue better than stretching alone

Stretching: Region-specific stretch item for the affected area, starting gently once fully healed

Massage: Scar mobilization - light circular and cross-friction work once the wound is fully closed; Back: Upper Back; Chest for thoracic scars

Also worth doing: Silicone sheeting for scar quality; start at 4-6 weeks or as cleared by the surgical team

Get it checked if: NEVER work an unhealed wound. Redness, heat, discharge or opening of the wound is infection - urgent

What the evidence says: Scar massage and progressive loading improve mobility and appearance. Timing is the safety point: fully healed first, always.

Prevalence basis: Surgical rehabilitation literature

What is going on: Excessive heart rate rise on standing with blood pooling in the legs and abdomen; deconditioning worsens it

Strength work: Start RECUMBENT - rowing, recumbent cycling, floor work; Legs: Quads; Glutes; Core: Transverse Abdominis; progress to upright over months

Stretching: Not primary

Massage: Legs: Calves - upward strokes

Also worth doing: Compression garments; salt and fluid as directed; slow graded progression over 3-6 months

Get it checked if: Fainting with injury, chest pain, or new arrhythmia needs cardiology review before exercising

What the evidence says: The Levine and CHOP protocols work by starting recumbent and progressing upright over months. Starting upright fails and puts people off exercise for good.

Prevalence basis: Autonomic medicine estimates

What is going on: Post-exertional malaise - a delayed worsening of all symptoms 12-72 h after exertion that is NOT deconditioning

Strength work: DO NOT prescribe progressive exercise to anyone with PEM. Pacing and staying within an energy envelope come first

Stretching: Very gentle passive or supported stretching only, well within tolerance

Massage: Light massage is generally well tolerated and may help

Also worth doing: Pacing, heart-rate ceilings, activity diaries; only consider very gradual strength work once PEM is stable

Get it checked if: Worsening after activity that lasts more than 24 hours is the defining feature - respect it. Graded exercise therapy has caused documented harm in this group

What the evidence says: THE MOST IMPORTANT SAFETY ENTRY ON THIS LIST. NICE withdrew its graded exercise therapy recommendation in 2021 after evidence of harm. If a user reports post-exertional crashes, the app must NOT push progression.

Prevalence basis: Post-viral illness epidemiology

What is going on: Apical chest breathing with an underused diaphragm, accessory muscle overwork and low CO2 tolerance

Strength work: Core: Diaphragm; Core: Transverse Abdominis - diaphragmatic and nasal breathing drills

Stretching: Chest; Trunk; Neck for accessory muscles

Massage: Neck & Shoulders; Chest; Back: Upper Back

Also worth doing: Nasal breathing; extended exhale; breath-hold tolerance work

Get it checked if: Breathlessness at rest, chest pain, or hypoxia needs medical assessment before being called a breathing pattern problem

What the evidence says: Breathing retraining improves symptoms across anxiety, asthma, reflux and neck pain. This is the single highest-leverage missing capability in the library - one new item serves seven conditions.

Prevalence basis: Respiratory physiology studies

What is going on: Pelvic floor muscle hypertonicity and central sensitization, often with a trigger that has since resolved

Strength work: Core: Pelvic Floor - RELAXATION and down-training; strengthening comes much later if at all

Stretching: Hips: Adductors; Hips: Flexors; Glutes: Piriformis

Massage: Glutes; internal pelvic floor release is specialist work

Also worth doing: Diaphragmatic breathing to down-regulate; dilator therapy where indicated

Get it checked if: New pain with bleeding, discharge or a lesion needs gynecological review first

What the evidence says: Pelvic floor physical therapy is first-line. As with male pelvic pain, KEGELS MAKE THIS WORSE - the app must not offer the same pelvic floor routine to the female incontinence entry and the female pelvic pain entry.

Prevalence basis: Gynecology epidemiology

What is going on: Somatosensory input from the neck and jaw converging on auditory pathways can modulate tinnitus loudness

Strength work: Neck; Back: Traps: Lower

Stretching: Neck; Jaw range work; Neck: Suboccipitals stretch

Massage: Neck & Shoulders; Neck: SCM; Jaw & Face; Neck: Suboccipitals massage

Also worth doing: Jaw and neck posture; stress management

Get it checked if: Sudden one-sided hearing loss with tinnitus is an ENT emergency; pulsatile tinnitus needs vascular imaging

What the evidence says: Only helps the subset whose tinnitus changes with neck or jaw movement. Evidence is limited - position it as worth trying, not as a treatment.

Prevalence basis: Audiology and tinnitus research

What is going on: Disturbed proprioceptive input from the upper cervical spine conflicts with vestibular and visual information

Strength work: Neck - deep cervical flexor endurance; Back: Traps: Lower; cervical joint position sense retraining; Neck: Deep Neck Flexors

Stretching: Neck; Shoulders

Massage: Neck & Shoulders; Neck: SCM; suboccipital release

Also worth doing: Head-eye coordination drills; balance training; the neck must be treated alongside the balance system

Get it checked if: Dizziness with hearing loss, neurological signs, or triggered purely by position changes in bed (BPPV) is a different diagnosis - exclude those first

What the evidence says: Manual therapy plus cervical proprioceptive retraining improves dizziness and balance. Only appropriate once vestibular and central causes are excluded.

Prevalence basis: Vestibular and musculoskeletal literature

What is going on: The scapula grates over the ribcage, from bursal thickening, muscle atrophy or a bony prominence

Strength work: Shoulders: Serratus Anterior; Back: Traps: Lower and Middle; Back: Rhomboids - restore the muscular cushion between scapula and ribs

Stretching: Chest; Back: Lats

Massage: Back: Upper Back

Also worth doing: Posture work; avoid repeated provocative overhead motions while irritable

Get it checked if: Painless crepitus needs no treatment; a hard bony clunk with pain may need imaging for an osteochondroma

What the evidence says: Strengthening the periscapular muscles restores the soft-tissue cushion. Painless snapping is benign and needs nothing but reassurance.

Prevalence basis: Shoulder clinic series

What is going on: Irritation of the greater or lesser occipital nerve as it passes through the suboccipital muscles

Strength work: Neck - deep cervical flexor endurance; Back: Traps: Lower; Neck: Deep Neck Flexors

Stretching: Neck; suboccipital stretch; Neck: Suboccipitals stretch

Massage: Neck & Shoulders; suboccipital release; Neck: SCM; Neck: Suboccipitals massage

Also worth doing: Pillow height; screen position

Get it checked if: Sudden severe occipital headache is a red flag for hemorrhage - emergency

What the evidence says: Suboccipital release and posture work help; nerve blocks are the medical option. Limited exercise evidence.

Prevalence basis: Headache epidemiology

What is going on: Peripheral vasoconstriction; low muscle mass and inactivity reduce peripheral perfusion

Strength work: Hands, Fingers, Forearms, Grip; Legs: Calves; Full Body

Stretching: Hands, Fingers, Wrists; Feet, Toes, Ankles

Massage: Hands, Fingers; Feet, Toes, Ankles

Also worth doing: Layering; avoid nicotine; warm-up before cold exposure

Get it checked if: Color change through white-blue-red with pain, or ulceration at the fingertips, needs rheumatology - it can signal connective tissue disease

What the evidence says: Exercise improves peripheral perfusion. Massage gives short-term warming. Neither cures Raynaud.

Prevalence basis: Vascular epidemiology

What is going on: Moderate regular exercise improves immune surveillance; both inactivity and excessive training volume impair it

Strength work: Full Body; moderate resistance training 2-3x/week

Stretching: Full Body

Massage: Professional Massage - for sleep and stress, which affect immunity more than massage does directly

Also worth doing: Sleep, which matters more than any exercise variable here; do not train hard while febrile

Get it checked if: Fever with chest symptoms means no exercise. Frequent severe infections, or infections that will not clear, need medical investigation

What the evidence says: Moderate regular exercise reduces respiratory infection frequency and severity. Very high training loads temporarily increase susceptibility - the relationship is a J-curve, not a straight line.

Prevalence basis: Infectious disease surveillance

What is going on: Prolonged immobility in hip and knee flexion with venous stasis

Strength work: Legs: Calves - seated calf raises and ankle pumps hourly; Glutes: Max

Stretching: Hips: Flexors; Legs: Hamstrings; Neck; Spine

Massage: Legs: Calves after arrival; Feet, Toes, Ankles

Also worth doing: Hydration; compression socks; walk every 1-2 hours

Get it checked if: Calf pain and swelling after travel - possible DVT, urgent, do NOT massage

What the evidence says: Simple ankle pumps and walking breaks reduce stasis. Compression stockings have good evidence for flight DVT prevention.

Prevalence basis: Travel medicine data

What is going on: Static standing with minimal muscle pumping causes venous pooling, foot fatigue and lumbar compression

Strength work: Legs: Calves; Glutes: Med; Feet, Toes, Ankles; Core: Transverse Abdominis

Stretching: Legs: Calves; Hips: Flexors; Back: Lower Back; Feet, Toes, Ankles

Massage: Feet, Toes, Ankles; Legs: Calves; Massage Ball

Also worth doing: Anti-fatigue mat; footwear rotation; alternate a foot on a low rail; compression socks

Get it checked if: New one-sided leg swelling; varicose vein ulceration

What the evidence says: Movement variety beats any single intervention. Calf pumping and footwear matter most.

Prevalence basis: Occupational health surveys

What is going on: Inflammation of the facial nerve producing one-sided facial weakness; most recover substantially within months

Strength work: Facial muscle retraining under guidance - NOT forced maximal effort, which encourages synkinesis

Stretching: Gentle facial stretch and relaxation work

Massage: Jaw & Face; Neck & Shoulders - light facial massage for comfort and circulation

Also worth doing: Eye protection while the eye will not close is the priority; mirror biofeedback retraining

Get it checked if: SUDDEN FACIAL DROOP MUST HAVE STROKE EXCLUDED IMMEDIATELY. Bell palsy affects the forehead too; a stroke usually spares it - but never make that call at home

What the evidence says: Tailored facial retraining with biofeedback improves outcome and reduces synkinesis. Vigorous maximal facial exercise makes synkinesis worse - the intensity matters in the opposite direction from most training.

Prevalence basis: Neurology epidemiology

What is going on: Sustained asymmetric load causes shoulder elevation, lateral trunk flexion and compensatory hip drop

Strength work: Back: Traps: Lower; Abs: Obliques; Back: QL; Glutes: Med; loaded carries on BOTH sides

Stretching: Back: QL area; Back: Lats; Neck; Trunk

Massage: Back: QL; Neck & Shoulders; Back: Upper Back

Also worth doing: Use a backpack with both straps; alternate sides; lighten the load

Get it checked if: Persistent one-sided numbness in the hand suggests thoracic outlet or nerve compression

What the evidence says: Suitcase carries loaded on the weaker side correct the asymmetry better than stretching the tight side.

Prevalence basis: Occupational and ergonomic studies

What is going on: Repeated lifting from a flexed rotated position, sustained feeding postures, and thumb-abducted carrying of a rapidly growing load

Strength work: Back: Traps: Lower; Glutes: Max; Core: Transverse Abdominis; Arms: Forearms: Wrist Extensors; Hands, Fingers, Forearms, Grip

Stretching: Neck; Chest; Hips: Flexors; Back: Lower Back

Massage: Neck & Shoulders; Back: Upper Back; Arms: Forearms; Hands, Fingers

Also worth doing: Feeding with support so the shoulders are not held up; hinge to lift from the crib; scoop rather than pinch when lifting the baby

Get it checked if: Postpartum red flags: severe headache, heavy bleeding, calf pain, or mood crisis - urgent

What the evidence says: Very high-value routine: the population is large, motivated and time-poor. Keep it under 10 minutes.

Prevalence basis: Postpartum musculoskeletal studies

What is going on: Poorly understood - immature gut motility, feeding factors and infant temperament all contribute. Whatever the cause, the crying is real and the effect on parents is the bigger problem

Strength work: Not applicable at this age

Stretching: Gentle leg-cycling and knees-to-tummy movements

Massage: Infant abdominal massage in a clockwise direction following the colon, plus back and leg stroking, 10-15 minutes once or twice a day using a plain oil

Also worth doing: Holding and motion; parent rest and support matters as much as anything done to the baby

Get it checked if: Fever, vomiting, blood in the stool, poor feeding, or a baby who is floppy or hard to rouse is NOT colic - urgent pediatric assessment. Crying that starts after 4 months or that suddenly changes in character also needs review

What the evidence says: Infant massage reduces crying time in several RCTs, with an effect roughly comparable to the other things parents are offered. It also reliably reduces parental stress, which may matter more. Genuinely a massage-primary entry - one of very few on this list.

Prevalence basis: Pediatric epidemiology

What is going on: Sustained hip flexion with vibration exposure and a fixed lumbar position; the clutch or accelerator foot adds asymmetry

Strength work: Glutes: Max; Core: Transverse Abdominis; Back: Spinal Erectors

Stretching: Hips: Flexors; Back: Lower Back; Glutes: Piriformis; Neck

Massage: Back: QL; Glutes; Hips: Psoas

Also worth doing: Lumbar support; seat angle; stop every 90 minutes; do not sit on a wallet

Get it checked if: Leg numbness or weakness while driving needs assessment

What the evidence says: Getting out of the seat matters more than any single stretch. Build the routine around what can be done at a fuel stop.

Prevalence basis: Occupational health data

What is going on: Sustained flexion combined with rotation and lifting, in people who are otherwise sedentary all week

Strength work: Back: Spinal Erectors; Glutes: Max; Core: Transverse Abdominis; hip hinge patterning

Stretching: Hips: Flexors; Legs: Hamstrings; Back: Lower Back; Spine

Massage: Back: QL; Glutes; Legs: Hamstrings

Also worth doing: Kneel rather than stoop; alternate tasks every 20 minutes; warm up first

Get it checked if: Sudden severe pain with leg symptoms after lifting - see the low back pain red flags

What the evidence says: Preparation beats treatment. A five-minute warm-up before a three-hour garden session prevents most of these episodes.

Prevalence basis: Primary-care presentation patterns

What is going on: Chronic plantarflexion shortens the gastrocnemius and Achilles and shifts load to the forefoot

Strength work: Legs: Calves: Tibialis Anterior; Feet, Toes, Ankles; Legs: Calves: Gastrocnemius through full range

Stretching: Legs: Calves; Legs: Calves: Gastrocnemius; Legs: Calves: Soleus; Feet, Toes, Ankles; Feet, Toes, Ankles: Plantar Fascia stretch

Massage: Legs: Calves; Feet, Toes, Ankles; Massage Ball; Feet, Toes, Ankles: Plantar Fascia massage

Also worth doing: Vary heel height day to day; flats with real support, not flimsy ones

Get it checked if: Sudden calf pain when changing to flat shoes could be an Achilles injury

What the evidence says: Consistent daily calf stretching restores dorsiflexion range over weeks. Switching abruptly to flats causes its own problems - transition gradually.

Prevalence basis: Foot biomechanics studies

What is going on: Reduced overnight movement plus sustained end-range sleeping positions; disc hydration peaks in the morning making early flexion less tolerable

Strength work: Core: Transverse Abdominis; Glutes: Max - later in the day, not first thing

Stretching: Full Body; Spine; Hips: Flexors; Neck - gentle on waking

Massage: Neck & Shoulders; Back: Upper Back

Also worth doing: Pillow height matched to sleep position; pillow between knees for side sleepers; avoid deep spinal flexion in the first hour after waking

Get it checked if: Morning stiffness lasting over an hour with joint swelling suggests inflammatory arthritis - refer

What the evidence says: Gentle movement on waking works. Avoid heavy loaded spinal flexion within the first hour - the discs are at their most hydrated and least tolerant.

Prevalence basis: Rheumatology and sleep studies

What is going on: Sustained low-level contraction in small muscles held in fixed positions for hours without variation

Strength work: Arms: Forearms: Wrist Extensors and Flexors; Hands, Fingers, Forearms, Grip; Back: Traps: Lower; Shoulders: Serratus Anterior

Stretching: Hands, Fingers, Wrists; Neck; Chest; Back: Mid-Back

Massage: Arms: Forearms; Hands, Fingers; Neck & Shoulders

Also worth doing: Practice in blocks with breaks; vary posture; progressive load rather than sudden practice increases

Get it checked if: Persistent numbness, loss of fine control, or involuntary curling of a finger during play could be focal dystonia - specialist referral, and it is made worse by pushing through

What the evidence says: Load management plus antagonist strengthening. Never push through hand pain in a performer - it ends careers.

Prevalence basis: Performing arts medicine surveys

What is going on: Inability to maintain a braced neutral trunk under load means the spine absorbs what the hips should

Strength work: Core: Transverse Abdominis; Abs: Obliques; Back: Spinal Erectors; Glutes: Max; loaded carries; hip hinge patterning

Stretching: Hips: Flexors; Legs: Hamstrings; Legs: Calves - ankle range limits squat depth

Massage: Back: QL; Glutes

Also worth doing: Bracing technique; hip hinge practice unloaded before loaded

Get it checked if: See low back pain red flags

What the evidence says: Core endurance predicts back injury better than core strength. Train for time under tension, not maximum reps.

Prevalence basis: Occupational back injury data

What is going on: Progressive fibrosis of the palmar fascia pulling fingers into flexion. It is a fibrotic disease, not a muscle or tendon problem

Strength work: Not effective

Stretching: Not effective - stretching does not slow or reverse it

Massage: Not effective

Also worth doing: Needle fasciotomy, collagenase injection, or surgery when the hand no longer lies flat on a table

Get it checked if: Refer when the finger cannot be straightened on a tabletop test

What the evidence says: LISTED DELIBERATELY AS A NEGATIVE ENTRY: a recommendation engine should know what NOT to offer. Stretching a Dupuytren cord wastes the user's time and delays effective treatment.

Prevalence basis: Hand surgery epidemiology

What is going on: Displaced otoconia in a semicircular canal. It is a mechanical inner-ear problem, not a muscular one

Strength work: Not effective

Stretching: Not effective

Massage: Not effective

Also worth doing: Epley or Semont repositioning maneuvers resolve 80-90% in one or two treatments

Get it checked if: Vertigo with hearing loss, double vision, slurred speech or weakness is not BPPV - emergency

What the evidence says: SECOND NEGATIVE ENTRY: neck stretching is commonly and wrongly offered for dizziness. If a user reports positional vertigo lasting under a minute, the right answer is a repositioning maneuver from a clinician, not a routine.

Prevalence basis: Vestibular epidemiology

What is going on: Cauda equina syndrome, spinal fracture, spinal infection, malignancy, DVT, septic arthritis, cardiac chest pain, and abdominal aortic aneurysm can all present as back, hip, shoulder or chest pain

Strength work: NEVER prescribe exercise before these are excluded

Stretching: Never

Massage: NEVER massage a suspected DVT, infection, or fracture

Also worth doing: Immediate medical assessment

Get it checked if: Saddle numbness; bowel or bladder change; bilateral leg weakness; fever with back pain; unexplained weight loss; night pain that wakes; pain after significant trauma; hot swollen single joint; one-sided hot swollen calf; chest pain with breathlessness or sweating; pain in someone with a cancer history

What the evidence says: BUILD THIS FIRST. A short red-flag checklist shown before any pain-related routine converts this whole catalog from a liability into a responsible feature.

Prevalence basis: Emergency and primary-care red-flag literature

What is going on: Percussive and deep-pressure tools apply far more force than hands and are used without supervision, on areas people cannot see. Reported harms include nerve injury, rhabdomyolysis, fracture in low bone density, and dislodged clot

Strength work: NEVER over the front or side of the neck (carotid and vertebral arteries), the spine itself, the kidneys, the abdomen in pregnancy, or any bony prominence

Stretching: Not applicable

Massage: Do NOT use any tool on: a hot swollen painful calf (possible clot); numb skin or a neuropathic foot, where damage cannot be felt; an acute contusion or fresh injury; over a fracture or in known osteoporosis; over varicose veins, an open wound, an infection or an unhealed scar; or on anyone taking anticoagulants without advice

Also worth doing: Keep to 60-90 seconds per muscle, moderate pressure, and off bone. Pain is a stop signal, not a target

Get it checked if: A hot swollen one-sided calf, numbness, known low bone density, anticoagulant use, pregnancy, or any recent injury - do not use a tool, ask first

What the evidence says: A caution entry rather than a routine. The app names five massage tools and offers no technique guidance whatsoever; this is the content that should sit behind them before more massage routines ship.

Prevalence basis: Device injury reports and clinical guidance

What is going on: Same mechanism as Osteoporosis and osteopenia but routinely missed because it is thought of as a women's condition

Strength work: Heavy compound lifting plus impact work - identical protocol to Osteoporosis and osteopenia

Stretching: Avoid loaded end-range spinal flexion

Massage: Not primary

Also worth doing: Impact loading; balance work; vitamin D and calcium

Get it checked if: Any fragility fracture in a man over 50 should trigger a bone density scan - it usually does not

What the evidence says: Men account for a third of hip fractures and have higher post-fracture mortality than women. Worth a separate routine purely because nobody offers them one.

Prevalence basis: Bone density population data

What is going on: Prolonged sitting has metabolic effects independent of exercise volume - you cannot fully out-train 10 hours of stillness

Strength work: Full Body; any resistance work; even brief bouts count

Stretching: Hips: Flexors; Spine; Chest

Massage: Foam Roller Massage; Back: Upper Back

Also worth doing: Break sitting every 30 minutes; 2-3 minute movement snacks; standing desk alternation

Get it checked if: Chest pain or unusual breathlessness when starting activity

What the evidence says: Breaking up sitting improves glucose and blood pressure independently of a daily workout. Short frequent bouts are the intervention with the best adherence.

Prevalence basis: WHO physical activity surveillance
