Assume starting position. Gently tap the toe of the extended right leg on the floor, then return leg to the raised position. Don't swing the leg up and down; this is a small, controlled movement. Do 20 taps; then, keeping the leg extended and raised, do six push-ups. You don't need to bring your chin to the floor—halfway down will do. Return right knee to floor. Repeat on left leg (that's one set). Do four sets; between each, rest for 30 seconds with both knees on the floor. This is Move One.
