oblique muscles?

Hey dude, if you cant balance while doing side sit ups, its all about finding the proper way to hook your feet together.I usually leave whatever side is down legon the bottom, and put the top of my other foot in the curve of the bottom of the opposite foot.

Hope that helps.

I remember saxon side bends. They were pure evil. Even with 5 lb dumbells it was tough.
