Things You'll Need:
- Exercise ball

Step 1
Sit down on the floor with your left leg off to the side and your right leg bent, with the knee touching the floor. Lay your right side against the exercise ball. If you need to alter the routine, sit on the floor with both knees bent and your side resting against the ball.

Step 2
Crunch to the left, holding your stomach muscles in tight. Your waist should bend to the left, with your elbow and head following.

Step 3
Release the motion and return to the ball. Repeat the crunch motion 10 to 12 times for a minimum of three reps.

Step 4
Switch sides and work your right side in the same manner as described above. Your right leg will now be bent and your left side touching the ball.
