Bodyweight Exercise: Ball Crunch

The ball crunch is similar to the basic abdominal crunch, except it is done on top of an exercise ball. This requires more balance, and as a result, recruits more core muscles to hold your body steady during the movement.

Step 1: Sit down on the ball and roll forward until the ball is under your back. Your feet should be feet flat on floor, knees bent 90 degrees, and your hands beside your ears.

Step 2: Contract your abs tightly and lift your shoulders towards the ceiling. Keep your eyes focused on the ceiling and do not pull your head forward.

Then lower back down and repeat.
