Also called: Sit-to-stand difficulty; leg weakness in daily life; needing your arms to stand up; stairs getting hard
Exercise is the main treatment
Strength
Balance
Needing your arms to stand up, or taking stairs one at a time with the rail. Standing up is the most demanding movement in an ordinary day, so it is the first thing to fail - and losing it starts a spiral of moving less that makes everything else worse.
How common: More than 6% of older adults living independently and over half of those in care cannot rise from a chair without difficulty; nearly two-thirds of falls in care homes start during the attempt
What it is
A chair rise needs quadriceps and glute power, enough ankle range for the shin to travel forward, and the balance to catch the body as it comes up. It is a genuinely hard movement, and it is done thirty or forty times a day without anyone noticing until it stops being easy.
Leg strength falls by roughly one to three per cent a year after fifty in people who do not train, and power falls faster still. The chair rise is where that first shows up, which makes it an early-warning signal rather than an inevitability - and one of the most trainable things on this entire list.
What it feels like
- Pushing off the arms of the chair without thinking about it
- Rocking forward two or three times to build momentum before standing
- Choosing the higher chair in a room without consciously deciding to
- Stairs taken one at a time, with the handrail, and going down feeling less safe than going up
- Standing up feeling unsteady for the first second or two
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.
- Quadriceps and glute weakness
- These are the muscles that extend the knee and hip against body weight. They shrink first and fastest with inactivity, and a chair rise is close to a maximal effort once they have declined.
- Loss of power rather than strength
- Standing up needs force delivered quickly. Power declines faster than maximum strength with age, which is why someone can still push hard slowly and still fail to get out of a low chair.
- Restricted ankle dorsiflexion
- The shin has to travel forward over the foot to bring the centre of mass over the base. Stiff ankles make the movement mechanically harder no matter how strong the legs are, and force a bigger forward lean.
- Balance and postural control
- The rise ends with the whole body mass over a small base. Poor balance makes the nervous system hesitate, and hesitation costs the momentum the movement depends on.
- The avoidance spiral
- Once standing up is hard, people sit for longer, choose higher chairs and move less. Each of those reduces leg strength further. The spiral is the reason this deteriorates faster than ageing alone would predict.
- A period of illness, surgery or bed rest
- A week in bed can cost an older adult a large share of leg muscle, and it is rarely regained by itself. Many people can date the change to a specific hospital stay.
- Knee or hip pain
- Arthritis makes the movement hurt at the deepest part, so people avoid the range, lose strength there, and find it harder still. Pain and weakness reinforce each other in both directions.
- Low protein intake and anabolic resistance
- Older muscle needs more protein and a bigger training stimulus for the same result, and older appetites tend to deliver less. The two work against each other.
- Body weight relative to leg strength
- The effort required is proportional to the load being lifted. Strength that was sufficient at one weight may not be at another, which is a mechanical fact rather than a judgement.
- Medication side effects
- Sedatives, blood pressure tablets causing dizziness on standing, and statins in a minority of people all affect either the strength or the confidence to stand quickly.
Who tends to get it
- Adults over sixty, and anyone over fifty who does no resistance training
- Anyone who has had a hospital stay, an operation or a long illness
- People with knee or hip osteoarthritis
- Anyone who has had a fall and become more cautious since
- People whose only exercise is walking, which does very little for leg strength
What makes it worse, and what settles it
Makes it worse
- Choosing higher chairs and using the arms every time, which removes the practice
- Long periods of sitting or bed rest
- Doing only walking or cycling and no strength work
- Avoiding stairs, which is the other daily strength stimulus most people have
- Waiting until it is a problem before starting, since the decline is much easier to prevent than reverse
Settles it
- Sit-to-stand practice from progressively lower seats, done as an exercise rather than only as a necessity
- Progressive leg strength work - loaded squats, leg press, step-ups - hard enough to be a real stimulus
- Power work: standing up fast, not just standing up
- Ankle range work so the mechanics stop fighting the strength
- Balance training, which addresses the part strength alone does not
What actually helps
The short version: Standing up is the most demanding everyday movement - it needs quadriceps and glute power, ankle range, and the balance to catch the body as it rises. Leg strength falls 1-3% a year after 50 unless trained, and a chair rise is the first thing that goes, which starts the spiral of moving less
Strength work: Chair Workout - Seated Sit-to-Stand as the exercise, done as sets; Legs: Quads - chair squats, box squats and step-ups; Glutes: Max; Glutes: Med; Legs: Hamstrings; Legs: Calves: Gastrocnemius; Floor Climb - stairs as the training, one flight at a time
Stretching: Hips: Flexors; Legs: Calves - ankle range limits how far forward you can get your weight
Massage: Not primary
Also worth doing: Count how many times you can stand from a chair in 30 seconds and write it down; a higher, firmer chair while you build up; hands on thighs, not on the arms of the chair; protein at every meal
What the evidence says: The 30-second chair stand test is a cornerstone of the CDC STEADI fall-prevention program and the Otago Exercise Program, and scoring below age norms predicts falls. Progressive leg strengthening reliably raises chair-rise count and stair speed at any age, including in the ninth decade.

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.

Get it checked if…
Weakness that came on over days rather than months, weakness on one side, or weakness with numbness, bladder change or falls - see a doctor; it may not be deconditioning
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
This responds fast and it responds at any age. Meaningful improvement in chair-rise ability usually appears within six to twelve weeks, and much of the early change is neural rather than muscular - the strength is partly there already and is being recruited better. The important part is that it must be trained deliberately and progressively; general activity and walking do not produce it. Once regained it is kept easily with two sessions a week.

Others the same routine covers
These share the Strength & Bone for Aging 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.
