Test 1 of 2
The 30-Second Chair Stand
- Sit on a sturdy chair, arms crossed over your chest.
- When the timer starts: stand up fully, sit back down. Repeat.
- Count every full stand-up. Stop when the timer ends.
Use a chair against a wall. Stop if you feel pain or dizziness.
Test 2 of 2
The One-Leg Balance Test
- Stand next to a wall or counter — fingertips ready, just in case.
- Lift one foot off the floor. Eyes open.
- Tap STOP the moment your foot touches down or you grab support.
Stay within arm's reach of support at all times.
Your time: 0.0s
