30-second chair stand
A measure of leg strength; low scores for your age suggest a higher risk of falls.
How to do it
Put the chair against a wall so it can't slide. Stop if you feel pain, dizziness or short of breath.
- Sit in the middle of the seat with your feet flat on the floor, shoulder width apart.
- Cross your arms over your chest, hands on the opposite shoulders.
- Start the timer. Stand all the way up, then sit all the way back down. Repeat as many times as you can in 30 seconds.
- Count each full stand. If you're more than halfway up when time runs out, count it.

What the research found
The test measures leg strength reliably: scores matched leg-press strength closely and gave much the same result when repeated. The CDC uses scores below the average for your age as a sign of higher fall risk.
Studied in: Adults 60 and over; norms from the CDC's falls program.
