Toe Touches (abs)
Toe Touches use your body's own leverage against gravity as resistance, targeting the lower abs for a chiseled result. Lie on your back with legs raised straight up toward the ceiling. Curl your shoulders off the floor and reach both hands up toward your toes, then lower back down with control without letting your legs drift or your lower back arch.
Medicine Ball Straight Leg Raises
Medicine Ball Straight Leg Raises add resistance to a classic lower-ab movement, using the weight of the ball to make bigger gains than the bodyweight-only version. Lie on your back holding a medicine ball between your feet or ankles, legs extended toward the ceiling. Lower your legs slowly toward the floor without letting your lower back arch, then raise them back up using your lower abs.
Medicine Ball Russian Twists
Medicine Ball Russian Twists are a great, well-known move for cutting the oblique abs, with the ball adding resistance to the classic bodyweight twist. Sit with your knees bent and heels on the floor (or lifted for more difficulty), leaning back slightly to engage your core. Holding a medicine ball with both hands, rotate side to side, tapping the ball near the floor on each side.
