After 50: not sit‑ups, not long runs – the 30‑second “sit‑to‑stand” test geriatricians use to spot early frailty

The GP asked her to stand up from the chair without using her hands. It sounded almost insultingly simple. She walked the dog, she gardened, she’d never run a marathon but she’d never thought of herself as “frail”. Thirty seconds later, she was breathing harder than expected – and surprised at how few stands she’d managed.

In geriatric clinics, this tiny slice of effort is not a party trick. It is one of the quickest ways to see how much “reserve” a body has left: the strength, balance and power that keep you independent when life throws illness, a fall or a spell of bedrest your way. It quietly predicts far more about future health than a six‑pack ever will.

Doctors call it the 30‑second chair stand, or sit‑to‑stand, test. You don’t need a treadmill, a gym membership or a wearable device. Just a solid chair, a timer and an honest attempt. What it reveals – especially after 50 – often surprises people who still feel relatively fit.

Because early frailty rarely announces itself with drama. It creeps in as “I just don’t get off the floor as easily” or “the stairs feel steeper than they used to”. The sit‑to‑stand test turns that vague feeling into a number you can track, and, crucially, change.

After 50, how powerfully you can get out of a chair matters more for independence than how far you can jog.

Why doctors watch how you get out of a chair

Geriatricians think in practical questions. Can you get to the loo in time? Can you recover if you trip on the kerb? Can you stand long enough to cook a meal? Sit‑ups and long runs don’t answer those. Standing up from a chair does.

When you rise from sitting, your body calls on almost everything that protects you from frailty: leg and hip strength, core control, balance, joint range and cardiovascular reserve. If one of those systems is struggling, it tends to show up here first. That makes the test a powerful “early warning light”.

Research has linked slower or more difficult sit‑to‑stand performance with a higher risk of:

• Falls and hip fractures.
• Needing help with daily tasks in future.
• Longer hospital stays and slower recovery after illness.
• Higher rates of chronic disease complications.

Doctors also like it because it is repeatable. If your number is drifting down year on year, that is a prompt to act long before you feel “old” in day‑to‑day life. And unlike a scan or blood test, the solution sits in your own muscles, not in a prescription.

What the 30‑second sit‑to‑stand test actually involves

In clinics, the test is done with a standard, armless chair and clear instructions. At home, you can replicate the essentials with a bit of care.

You will need:

• A sturdy chair without wheels, about knee‑height (roughly 43–46 cm).
• A flat, non‑slippery floor.
• A timer or phone.
• Ideally, another person nearby for safety.

The goal is simple: count how many times you can go from sitting to fully standing and back again in 30 seconds, using your legs rather than pushing off with your hands.

If you normally use a stick, frame or someone’s arm, you should only do this test with a professional who can supervise you.

How to try the test at home (safely)

Set things up first so you are not rushing or improvising halfway through.

1. Position the chair. Place it against a wall so it cannot slide backwards.
2. Sit correctly. Sit in the middle of the seat, back straight, feet flat on the floor, roughly shoulder‑width apart.
3. Arm position. Cross your arms over your chest, or place your hands lightly on your shoulders. (If that is impossible, resting fingertips on the seat for balance is acceptable, but note that down.)
4. Warm up briefly. March on the spot or walk around the room for 2–3 minutes.
5. Start the timer. When you hear “go”, stand up fully, then sit back down so your bottom touches the seat each time.
6. Find your rhythm. Move at a brisk but controlled pace; count only full stands.
7. Stop at 30 seconds. Note the total number of complete stands.

If you feel chest pain, severe breathlessness, dizziness, or sharp joint pain at any point, stop immediately and sit down. That in itself is valuable information to mention to your GP or practice nurse.

How to read your result (without panicking)

There is no single “magic number”. Age, sex, height, health conditions and training all influence performance. Exact cut‑offs also vary slightly between studies. But broad patterns are clear: numbers drift down with age, and very low scores in your 60s or 70s can flag reduced strength.

Very roughly, for adults without major mobility problems:

Age band	Typical range of stands in 30 seconds*
50–59	About 13–20
60–69	About 11–18
70–79	About 10–17
80+	About 8–15

*These are ballpark figures drawn from research on community‑dwelling adults. They are a guide, not a diagnosis.

How to make sense of your own number:

• Well within or above the typical range: reassuring, but still worth re‑checking once or twice a year.
• Just below the range for your age: a nudge to build more leg strength and balance work into weekly life.
• Markedly low (for example, fewer than about 8–10 stands in your 60s or 70s), or you cannot stand without using your hands: talk to your GP, practice nurse or a physiotherapist. It may signal early frailty, previous under‑the‑radar illness, or simply long‑standing inactivity that is now catching up.

The most useful comparison is not with a chart, but with yourself six or twelve months from now. The direction of travel matters more than one snapshot.

What to do if your score is low – or has fallen

A low sit‑to‑stand score is not a verdict. It is an invitation to train the exact abilities that keep you independent. The good news is that they respond surprisingly well, even in your 70s, 80s and beyond.

First, consider sharing the result with:

• Your GP or practice nurse, especially if you also feel slower, more tired, or have lost weight without trying.
• A physiotherapist, who can check technique, joint health and balance.
• If available in your area, a falls or strength‑and‑balance clinic.

They may check blood pressure, heart function, medication side‑effects, and screen for underlying problems such as anaemia, undernutrition or hidden heart disease. Sometimes the issue is not just “weak legs” but something treatable in the background.

Then, build a small, realistic plan. That might mean:

• A 10–15 minute strength routine most days.
• A supervised exercise group designed for over‑60s.
• A home physio programme after illness or surgery.

Your aim is not to chase an athlete’s score, but to edge your number up a little and, more importantly, to make everyday tasks feel easier.

Simple exercises that directly improve your sit‑to‑stand

You do not need machines or a gym to improve at this test. The best training looks very much like the test itself.

• Practice sit‑to‑stands.
  Start by standing up from a higher chair or adding a cushion. Do sets of 5–10 stands, 2–3 times a day, using hands lightly for balance if needed, and gradually reducing support.

• Wall or worktop squats.
  Stand holding a sturdy surface, feet shoulder‑width apart. Bend knees and hips slightly as if starting to sit, keeping heels down, then stand tall again. Aim for 2–3 sets of 8–12 reps.

• Heel raises.
  Holding the back of a chair, rise up onto your toes, pause, lower slowly. Builds calf strength and ankle stability that help with balance.

• Step‑ups.
  If safe, step up onto a low step or bottom stair with one foot, then down again, alternating legs.

Two or three sessions a week of this sort of work, plus a bit more walking, often make a noticeable difference within a couple of months. As you get stronger, your 30‑second count tends to follow.

Small daily habits that protect strength after 50

You do not have to overhaul your entire lifestyle. Tiny patterns add up.

• Take stairs where you can; climb them a little more briskly once or twice a day.
• Stand up during television advert breaks and do a few slow sit‑to‑stands.
• Carry shopping in two smaller bags rather than one heavy one to encourage more trips, not fewer.
• If you work at a desk, set a timer to stand and walk for 2–3 minutes every half‑hour.
• Prioritise enough protein in meals (especially breakfast and lunch) to support muscle repair.

Think of your legs as a savings account. Every stand, step and squat is a small deposit against future illness or injury.

When you should not do this test on your own

For some people, attempting the sit‑to‑stand test unsupervised is not wise. Get medical advice first, or only do it in a supervised setting, if you:

• Have unstable heart disease, recent chest pain, or uncontrolled high blood pressure.
• Feel dizzy, light‑headed or breathless even with minor exertion.
• Have had a recent hip, knee, back or abdominal operation, unless your surgeon or physio has cleared you.
• Use a walking frame, two sticks, or another person’s arm to get around indoors.
• Have a history of frequent falls or collapsing.

If in doubt, err on the side of caution and discuss it at your next appointment. There are gentler versions and alternative tests that clinicians can use safely.

Extra checks worth doing this week

If the idea of “frailty” feels remote, this is exactly the time to lay down protection. A short self‑audit can help.

• Try the 30‑second sit‑to‑stand and write down your score and today’s date.
• Notice how fast you normally walk; if friends say you have slowed, take that seriously.
• Ask yourself if you can comfortably:
  • Climb one flight of stairs without stopping.
  • Carry a full kettle across the kitchen.
  • Get up from the floor without pulling on furniture.

If any of those feel marginal, do not wait for a crisis. Early, modest strength work now is far easier than rebuilding from scratch after a fall, infection or hospital stay.

FAQ:

• Is the sit‑to‑stand test a diagnosis of frailty?
  No. It is one piece of the jigsaw. Doctors look at weight change, exhaustion, walking speed, grip strength, illnesses and medication as well as functional tests like this. A low score is a prompt for further assessment, not a label on its own.
• How often should I repeat the test?
  For most people, every 3–6 months is enough. If you are following an exercise programme or recovering from illness, monthly checks can be motivating, but avoid doing it so often that it becomes a strain.
• What if I need to use my hands to push up?
  Note that down and still count your stands. It means your legs alone are not yet strong enough to lift you easily, which is important information to share with a clinician and to guide your training.
• Can I do this test if I have arthritis in my knees or hips?
  Often, yes – with modifications and advice. Many people with arthritis benefit from strengthening. However, if the movement causes sharp pain, major swelling or limping that lasts, stop and discuss alternatives with a physiotherapist or GP.
• I’m in my 80s – is it too late to improve?
  Evidence says no. People in their 80s and 90s can gain strength, balance and confidence with tailored programmes. The goal is not perfection, but maintaining as much independence and ease as possible for as long as possible.
