Area Targeted: Abs
Set up: Sit on a fitness ball and slowly walk forward, rolling the ball under your body until the ball is under your upper body, from your butt to your shoulders. Your body should be slightly bent back following the curve of the all. Position your legs so that there is a 90 degree angle between your upper and lower legs. Bring your arms back with your finger tips by your ears.
Movement: Crunch up, raising your head, chest, and shoulders, bringing your rib cage towards your pelvis. When your back is no longer curved, lower back down to the starting position. Repeat.
Points To Remember:
1. Keep your lower back in contact with the ball throughout the movement.
2. Do not place your hands behind your head and pull your head up to crunch.
