Besides crunches, whats a good ab work out?
oh yeah! Mikababy.. new profile pic, nice... the "Bicycle" on your back works the best for my abs.
Most of the ones I do came off of this sitehttp://exercise.about.com/od/abs/ss/abexercises.htm
reverse crunches,planking,side planking, leg raises,scissors,mountain climbs,v sit ups and so many more.
