Your Longevity
Check-In

You'll need: A chair (standard height, no arms) and a timer.

How to do it:
1. Sit in the middle of the chair, back straight, arms crossed on your chest.
2. When the timer starts, stand all the way up, then sit all the way back down.
3. Repeat as many times as you can in 30 seconds.
4. Count each full stand.

You'll need: A timer and a wall or chair nearby for safety.

How to do it:
1. Stand on a firm surface. Place your hands on your hips.
2. Lift one foot off the ground — whichever leg you prefer.
3. Start the timer. Hold as long as you can (maximum 60 seconds).
4. Stop if your foot touches the ground, your hands leave your hips, or you need support.
5. Test both sides. Record the shorter time.

You'll need: 4 meters of clear floor space (about 13 feet) and a timer.

How to do it:
1. Mark a start line and a finish line 4 meters apart (use tape or shoes as markers).
2. Stand at the start line.
3. Walk to the finish line at your normal, comfortable pace — like you're walking to the mailbox.
4. Have someone time you, or time yourself. Do it twice and use the faster time.
