Cross your ankles and bend your legs. Inhale and lower your
chest down to the floor. Exhale and push with your
chest and arm muscles up to starting position and repeat. Progress to full-body pushups, where you extend your legs and, before you lower your chest toward the floor, you are balanced on your hands and the tips of your toes. Start with the same tight body position and also squeeze your thighs. You are toning your chest, shoulder, triceps, back, abdominal and hamstring muscles.
