Push-ups on an exercise ball target your chest muscles along with the abdominal muscles and butt to keep you steady on the ball. Doing push ups on an exercise works out the lower body more than a traditional push-up. Keeping your lower legs or shins on the ball will help you balance yourself during the push-up.
Lie with your belly on the ball and walk your hands forward until the ball rests under your legs.
Make sure that your hands are directly below your shoulders on the floor.
Inhale as you lower toward the floor with the upper body, bending your elbows out to the side.
Remember to keep your abdominal muscles tight to help you maintain your balance.
Straighten your elbows and exhale as you press back up into starting position.
Keep your back straight and in line with your head and the rest of your body. Complete ten repetitions.
