To learn how to do this exercise,
- Begin on your belly in the superman, or X position, with your arms and legs out wide.
- Inhale and lift your head, arms, chest, and legs off the floor, like Superman.
- Then as you exhale, lower your body and plant your palms and feet on the floor. Inhale to straighten your arms and lift into plank position (top of a push-up). Hold here briefly, then exhale and bend your elbows behind you as you lower down.
- This counts as one repetition. Complete 20, or as many as you can in one minute.
