This is a full-body exercise.
- Starting position: place feet in straps about 12 inches from the ground. Hamstrings, glutes, abdominals, inner thighs, and lats are engaged as the body moves into a plank position.
- With legs together do five push-ups.
- Then, holding the plank, open and close legs five times — keep legs straight.
Repeat three times for one set.
