Beyond crunches
Each rep begins from a seated position on the glute-ham developer under the wall-ball target. The ball is lowered back, with arms overhead, until it touches the ground. With the snap of the knees and powerful flexion of the hip that characterize the glute-ham sit-up, the ball is launched to the target and then rebounds back into the athlete's hands, ready for the next rep.


Enough of those will mess you up...I think 10 for me.
