How to do it

Lie face down on the floor, with your arms extended out to your side, palms pressed to the floor. This will be your starting position.
To begin, flex one knee and bring that leg across the back of your body, attempting to touch it to the ground near the opposite hand.
Promptly return the leg to the starting postion, and quickly repeat with the other leg. Continue alternating for 10-20 repetitions.

When to stop

Stop and rest if you feel chest pain or pressure, are more short of breath than you'd expect, feel dizzy or faint, or have sudden pain. If chest pain or faintness doesn't pass when you rest, call 911.
