Ok Planks aren't so bad but...how do I describe this upside down sitting up holding a medicine ball and twisting side to side while your legs are holding you upside down while you are sitting up, kinda like a sit up but without going down! I know makes no sense, but my legs sure didn't like it..and I almost had to use my one wuss out, but PT had me drop the medicine ball and I was able to complete the reps! Yipee
I really like the sit on my butt and pull (kinda like rowing but with one hand)It was fun and NOTHING HURT!
