How strong and steady are you?

A 5 to 10 minute self-check in three parts. Your numbers are compared with published ranges for your age. Everything stays on your device.

Read this first

This is a screening tool, not a diagnosis or medical advice. Do the chair stand only if you can safely stand up without help, with a sturdy chair against a wall and, ideally, someone beside you. Skip it if you've fallen recently, feel dizzy when standing, or have been told not to.

About you

The published tables are split by sex. Choose "Show both" if you prefer.

Part 1: Fall-risk checklist

Tick each statement that is true for you. This is the CDC's "Stay Independent" checklist.

Part 2: 30-second chair stand

  1. Use a firm chair without arms, about 17 inches (43 cm) high, with its back against a wall.
  2. Sit in the middle of the seat, feet flat, arms crossed at the wrists against your chest.
  3. Start the timer. Stand up fully, then sit back down fully. Repeat as many times as you can in 30 seconds.
  4. If you're more than halfway up when time runs out, count it. If you need your hands to stand, stop: your score is 0, which is useful information too.

Below the range is what the CDC calls "below average", which it says indicates a risk for falls. Sources: Rikli RE, Jones CJ.

Part 3: 30-second arm curl (optional)

Women use a 5 lb (2.3 kg) weight, men an 8 lb (3.6 kg) weight. The ranges only apply at these weights. If you don't have the right weight, skip this part, because the ranges won't apply.

  1. Sit near the edge of the chair, back straight, feet flat.
  2. Hold the weight in your stronger hand, arm straight down by your side, palm facing in.
  3. Curl the weight up, turning your palm up as you lift, then lower it all the way. Count full curls in 30 seconds.
