The chair test, and what your number means
It's the most useful fitness test almost nobody has heard of: count how many times you can stand up from a chair in thirty seconds. No equipment, no skill, and it responds to training faster than almost anything else you could measure at home.
How to do it properly
Use a stable, armless chair on a hard floor — not a sofa, not a wheeled office chair. Sit with your arms crossed over your chest. Stand all the way up and sit all the way down, repeatedly, for thirty seconds. Count full repetitions. Use the same chair every time; a different seat height changes the number and makes the comparison meaningless.
If you need support, use it
A hand on a counter or the chair back is not cheating, it's a different version of the test. Record which version you used and stay with it. Switching between supported and unsupported mid-way through a training block produces a change in the number that has nothing to do with your legs.
What the published norms actually cover
The widely cited reference values come from Rikli and Jones and cover ages 60 to 95. Separate data exists for healthy young adults aged roughly 19 to 35. Between about 36 and 59 — which is a very large part of the population who might want this test — there is little solid normative data.
Compare against yourself instead
Given the gaps in the norms, the more useful comparison is your own count a fortnight ago. Deconditioned people improve quickly, often visibly within two weeks, and a personal trend sidesteps the question of what's average for your age entirely. It's also more motivating: going from six to nine is unambiguous progress in a way that a percentile isn't.
FAQ
How many sit-to-stands should I be able to do in 30 seconds?
For adults aged 60 to 64, published reference ranges sit around 12 to 19 depending on sex. Healthy young adults typically score considerably higher. For most middle-aged adults there is no good published norm, which is why tracking your own change over time is more informative than chasing a target.
Can I use a sofa or an armchair?
It's better than not testing, but the result won't be comparable to a standard chair, and soft seats make the movement significantly harder and less consistent. If a dining chair isn't available, the edge of a bed works — just record which you used and stay with it.
What if I can only do two or three?
That's your starting number. It's a measurement, not a verdict, and it's exactly the situation where the count improves fastest with a little consistent work.
How often should I test?
Weekly is a good balance. It moves fast enough to show change at that interval, and testing more often mostly measures noise and how tired you happen to be that day.
