The Six-Pack Ab Moves Your Trainer Didn't Tell You About


Start by lying down on your back with straight legs. Raise your hands above your head until they're fully extended. Sit up and lift your feet and hands about six inches off the floor. Gently start to rock back and forth, holding this hollow-body position the entire time. Build up momentum until you're rolling up onto your shoulders, but never let your heels touch the ground. Allow yourself to rock back and repeat.
