The 30-Second Chair Test That Can Reveal How Well You’re Ageing

It sounds almost too simple to matter: how many times can you stand up fully from a chair and sit back down again in 30 seconds? Yet this “sit-to-stand” test, already used by doctors to screen older patients, can offer a surprisingly detailed snapshot of someone’s overall health, and it can be done at home with nothing more than a stopwatch and an armless chair with a straight back.

“It’s a really helpful test, because it tells us so much about how well people are functioning,” says Jugdeep Dhesi, a consultant geriatrician at Guy’s and St Thomas’ NHS Foundation Trust and a professor of geriatric medicine at King’s College London. According to Dhesi, the test reflects strength, balance and flexibility, and research links poor results to a higher risk of falls, cardiovascular problems, and even death.

To try it, sit in the middle of the chair with arms crossed and hands resting on opposite shoulders, feet flat on the floor. Start the timer, rise to a full stand, sit back down, and repeat as many times as possible in 30 seconds.

What counts as a good score

The US Centers for Disease Control and Prevention publishes typical scores by age: a man aged 60-64 averages 14 repetitions, a woman the same age averages 12, while people in their late 80s average around eight. Scoring well below your age group’s average may signal a greater risk of falling, though the figures don’t account for recent surgery or injury. The test isn’t just for older adults, either, a Swiss study of nearly 7,000 people found 20-to-24-year-olds averaged around 50 repetitions a minute for men and 47 for women, with some managing more than 70, and separate research has linked performance on the test to aerobic fitness more broadly. Poor scores have also been used to flag patients at greater risk of complications after surgery or cancer treatment, and may point to underlying heart or lung weakness.

The stakes are real. Roughly 30% of people over 65 fall each year, rising to about half of those over 80, and a single fall can trigger lasting anxiety that keeps people at home. “If you’re worried about falling, you’re not [necessarily] going to go out and meet people and do other things. So it becomes a bit of a vicious circle,” Dhesi says. Beyond isolation, falls can cause serious harm: the UK records around 70,000 hip fractures a year, and roughly 30% of those patients die within twelve months, according to Dhesi. One 2012 study even found that people with the lowest scores on a similar test were five to six times more likely to die within six years than top scorers, though Dhesi stresses the test can guide treatment decisions rather than predict exactly how long someone will live.

Improving your score, she says, mostly comes down to staying mobile: seated exercises for those who struggle, standing up every hour or two, climbing stairs several times a day, and avoiding what Dhesi calls “bungalow legs”, weakened legs from living somewhere without stairs. Joining a low-cost exercise class for older adults adds a social element that Dhesi says is just as valuable as the physical one, since loneliness itself takes a toll on health. Everyday habits help too: doing housework, gardening, walking to the shops instead of driving, or simply getting down on the floor to play with grandchildren.
