Just a quick hint, on the pulldown abs do these on a pulldown machine while standing. Put your legs on either side of the seat and squeeze your legs in hard against the seat then do the pulldowns. Louie had this tested and it activates the muscles of the abs way more than normal. Also, if your doing normal situps with weights, try putting a medicine ball between your legs for the same reason. I can't remember the percent improvement but it was very considerable, definately worth trying. Also, on GHR situps, start out slow, I saw a westside video where Chuck put a 25 behind his head to do these. So I figured I could do that too. WRONG. Almost killed myself. Now I use a 10# weight and still have trouble. THese are real hard, but they seem to work better than some others. Good luck
