You won't get rid of fat doing crunches (fast and effective enough), two key points: proper timely nutrition and aerobics/cardio (in that order). Forget the rest if you want to [seriously] lose weight.

Somehow undergrip works better for me: I can lift myself 20 times @ 180 lbs (total in 3 sets) with any grip, but under- one, I feel like it's mobilizing more muscles and I feel less sore morning after.
