- Start on your hands and knees.
- Extend your left leg behind you so it's parallel with the floor. Engage your abs.
- With your leg extended, bend your elbows lowering your torso toward the floor while keeping your left heel in line with your left hip. Straighten your elbows to push yourself away from the floor.
- This counts as one rep. Be sure to do the same number of reps on each side.
