Do 8 triceps dips on a sturdy chair

Lower and raise your body using the edge of a stable seat.

Why it helps

Dips work the backs of your arms, which don't get much use in daily life. A few reps are plenty to start.

How to do it

1. Sit on the edge of a sturdy chair, hands gripping beside your hips.
2. Slide forward so your hips are off the seat, knees bent.
3. Bend your elbows to lower a few inches, then press up. Repeat eight times.

Make it easier

Keep your feet close and lower only a little.

Make it harder

Straighten your legs out in front.

Use a chair that will not slide, and stop if your shoulders hurt.
