This is a less stressful version of a hanging leg raise. It isolates the rectus abdominis, especially the lower half as well as the intercostal muscles.
How to do:
1. Hang on a chin bar using an overhand grip with arms straight at shoulder width.
2. Bend your legs about 15 degrees and keep them bent and relaxed during the entire exercise.
3. Pull your knees up to your chest while bending your knees. Be careful to move only your legs.
4. Hold this contracted position for a slow count of 1-2 seconds
5. Return slowly to starting position
6. Repeat repetitions until fatigued.
7. You may add alternate twists to involve the intercostal muscles more fully.
