Also called: Endometriosis; endo; adenomyosis

Exercise strongly helps Stretch Massage Strength

Tissue like the womb lining growing outside it, driving inflammation and pain that exercise cannot reach. What exercise can reach is the second layer built on top over years - a pelvic floor that has forgotten how to let go, trigger points in the abdominal wall, and hips stiffened around a protective posture.

How common: Around 10% of women of reproductive age - over 200 million worldwide. Close to half have chronic pelvic pain and about 70% have severe period pain

What it is

Endometriosis is a real, inflammatory, often severe disease in which tissue resembling the uterine lining grows outside the uterus, bleeds cyclically and causes inflammation, adhesions and pain. Nothing on this page treats that, and it is important to say so plainly: the average time to diagnosis is still measured in years, and physical therapy is not a substitute for it.

What builds on top of it, though, is treatable. Years of pelvic pain produce a chronically overactive pelvic floor, guarded and tender abdominal wall muscles, stiff hips held in a protective position, and a sensitised nervous system. In many women that secondary layer accounts for a substantial share of the day-to-day pain, and it responds to work that the disease itself does not.

What it feels like

  • Severe period pain, often starting before the bleeding does
  • Pelvic pain on other days of the cycle too, not only during a period
  • Deep pain during or after sex
  • Pain with bowel movements or urination, particularly around a period
  • Exhaustion, and a tight, braced feeling through the abdomen and hips

What causes it

Most people have more than one of these at once, and they feed each other. Read the list looking for the two or three that sound like your week rather than for the one true answer — the ones that describe you are the ones worth acting on.

The endometriosis itself
Lesions outside the uterus bleed and inflame cyclically, producing adhesions that tether organs to one another. This is the primary driver and it needs medical and often surgical management.
A chronically overactive pelvic floor
Years of guarding against pelvic pain leaves the pelvic floor muscles unable to relax. An overactive pelvic floor produces its own pain, painful sex and bladder and bowel symptoms, and it is frequently the most treatable layer.
Abdominal wall trigger points
The abdominal muscles brace against pain for years and develop tender points that refer pain across the lower abdomen. These are often mistaken for the disease and respond to soft tissue treatment.
Hips stiffened in a protective posture
A body in pain adopts a guarded position and holds it. The hip flexors, adductors and deep rotators shorten around it, adding a mechanical layer of stiffness and ache.
Central sensitisation
Persistent pain over years makes the nervous system more efficient at producing pain. This is why pain often continues after surgical treatment of the lesions, and why it is not a sign that nothing was found.
Scar tissue and adhesions
Both from the disease and from surgery, adhesions tether tissue that should slide, so ordinary movement pulls on structures that used to be free.
Fatigue and reduced activity
The disease is exhausting and activity falls, which weakens the trunk and hips and reduces the tolerance for movement further - a deconditioning loop on top of everything else.
The years before diagnosis
Being told for a decade that severe period pain is normal has real physical consequences: more years of guarding, more sensitisation, and less confidence in one's own body signals.

Who tends to get it

  • Anyone with severe period pain that has never been properly investigated
  • Women with a family history of endometriosis
  • Anyone with pain during sex, or with bowel or bladder pain around their period
  • Women whose pain persists after surgical treatment, in whom the secondary layer is likely dominant
  • Anyone who has been unwell and inactive for a long period

What makes it worse, and what settles it

Makes it worse

  • Kegels and pelvic floor squeezing, which is the wrong direction entirely for an overactive pelvic floor
  • High-intensity abdominal work during a flare
  • Long periods of inactivity between flares, which reduces tolerance further
  • Treating it as a purely muscular problem and delaying medical assessment
  • Being told it is normal, which delays everything

Settles it

  • Pelvic floor down-training - learning to release rather than squeeze, usually with a specialist pelvic health physiotherapist
  • Diaphragmatic breathing, which relaxes the pelvic floor directly
  • Gentle hip and adductor stretching to undo the protective posture
  • Abdominal wall soft tissue work and trigger point release
  • Graded, paced activity built to a level that can be repeated tomorrow rather than to what a good day allows

What actually helps

The short version: Tissue like the womb lining growing outside it, driving inflammation and pain. That part is not something exercise reaches. What it can reach is the second layer that builds on top over years - a pelvic floor that has been guarding so long it will not let go, trigger points in the abdominal wall, and hips that stiffened around a protective posture

Strength work: Core: Pelvic Floor - DOWN-training first, strengthening only later and only if a clinician says the floor is weak rather than overactive; Abs: Transverse Abdominis; Glutes: Max; Glutes: Med; Full Body - gentle general conditioning on the good days

Stretching: Hips: Flexors; Hips: Adductors; Hips: Piriformis; Spine; Hips

Massage: Abdomen; Back: Quadratus Lumborum (QL); Glutes; Hips: Psoas; Scars & Adhesions after surgery

Also worth doing: Heat. Keep the medical treatment going. Track symptoms against the cycle so the work can be dosed to the week rather than guessed at day by day

What the evidence says: Physiotherapy reduces endometriosis-associated pelvic pain, and the clearest effect comes from locally applied work - pelvic floor down-training improved painful sex and chronic pelvic pain in randomised trials. Be straight about the rest: a 2025 systematic review could include only ONE exercise-therapy trial, so general exercise here is a reasonable bet rather than a proven treatment, and none of it treats the disease itself.

The qFIT routine for this

Ready-made routinePelvic Floor & Core Recovery

qFIT already has this one built. It runs massage first, then stretching, then strength — the order that works on a body that is already sore — and every activity in it carries the reason it is there.

The button below opens your Checklist with this routine already selected, so instead of your whole list you land on just its Categories, Targets and Exercises, each with its checkbox, ready to tick as you work through them.

Have more than one problem? Tick yours under My Problems on My Profile and your Checklist's Routine list gains Recommended for my problems — every routine for the problems you picked, merged into one. Your picks stay private; that filter is the only thing they feed.

Get it checked if…

New or changing pain; heavy bleeding with dizziness or breathlessness; a hard swollen abdomen; fever; pain with a change in bowel or bladder habit - and any pelvic pain that has never been assessed. This is a diagnosis to have, not one to assume

And whatever the body part: chest pain or unusual breathlessness on exertion; a fever alongside the pain; unexplained weight loss; pain that is constant and unrelated to how you move; new numbness, weakness or loss of bladder or bowel control; or one calf that is swollen, warm and painful. Any of those, stop and get assessed.

How it usually goes

The disease needs a gynaecologist and often surgery, and this work sits alongside that rather than instead of it. Where the secondary layer is significant - and in long-standing endometriosis it usually is - pelvic floor and soft tissue work makes a real difference over three to six months, particularly to painful sex, bladder symptoms and the everyday background pain between periods. It is worth seeking out a pelvic health physiotherapist specifically; this is not general exercise territory.

Prevalence basis: WHO global prevalence estimates and endometriosis symptom cohort studies

Others the same routine covers

These share the Pelvic Floor & Core Recovery routine, so the work is the same. If one of them also sounds like you, that is a reason to expect more from it, not less.

This is general information, not a diagnosis, and it cannot examine you. If it matches you, use it to ask better questions of a clinician rather than to replace one.
