Instructions: Grasp and hang from a pull up bar with slightly wider-than-shoulder width overhand grip. Raise legs by flexing hips and knees until hips are completely flexed or knees are well above hips. Return until hips and knees are extended downward. Repeat. Leg raises are superb exercises for increasing the strength of your abs and building abdominal muscle. They are performed regularly by athletes to maintain their six-pack!
