This is a very difficult ab exercise. Lie on your back, your legs straight and feet in the air. Your hands should be outstretched at your sides.
Begin by slowly lowering your legs (keep them straight) to one side. Try to keep your shoulders on the ground. Do not let them flop or hit the ground. Once they get close to the ground, bring them back up to the starting position. Repeat on the other side.
