This exercise is designed to be performed on a Body-Solid Tools Stability Ball. Stability Balls can be used to perform a variety of balance, core training, strength, flexibility and rehabilitation exercises that target the abdominals, hips, glutes, back and upper body.
Lie down holding an exercise ball with legs raised so that the shins are parallel to the floor. Crunch up, lifting head, shoulders and back off the floor and place the exercise ball between the lower legs. Then, lie back down, extending legs out without touching the ground.
Crunch back up, grab the ball, and return to starting position.
