Starting Position: Sit on the ball and slowly walk out so that your back comes in contact with the ball. Walk out until your shoulders are in the middle of the ball. Squeeze your butt to lift your trunk into a table top position with knees bent to 90 degrees. Extend your arms out in front of you with palms touching.
Procedure: Keep your glutes squeezed and turn your shoulders to the right until they are vertical, yet your hips remain horizontal. Try not to drop your hips.
Where: You should feel this in your glutes and the sides of your trunk.
Make it harder: Roll farther onto your shoulder, progress to holding a dumbbell in your hands.
