The hanging leg raise is an exercise that really targets the ab muscles. There are straps available that hand on your chinup bar that can help you by relieving some of the tension from your arms while performing these. But be careful. I seem to develop shoulder problems when using the straps.
You will want to begin by raising your knees up to your chest and beyond. The higher you raise them, the more stress you put on your abs. It may be hard to do more than a couple reps when you start, but keep with it and you will love the results.
Once you master these, you can start to do straight leg lifts. You raise your legs and try to go high enough to form a V with your legs and body. Extremely tough so work on your knee ups first.
