Swiss Ball Crunch

Target Muscles
Rectus abdominis (mainly upper portion), transverse abdomins.


Starting Position
Lie across the ball, place your feet on the floor and keep your legs bent at the knees. Adjust your position so that the ball is com­fortably positioned in the small of your back.
Cross your arms over your chest, or, to make the exercise harder, place your hands by the sides of your head.
The Movement
Making sure that you move only your upper body and that your lower back remains in contact with the ball, slowly raise your torso.
Hold the position for a count of two; then lower yourself back to the starting position.
Tips
When you lower yourself back down, keep the movement controlled.
Do not let your upper body arch backwards or your head flop back over the ball.
To make the movement harder, bring your whole body higher up on to the top of the ball.
