Start behind the ball, place your midsection on the ball and roll forward until your hands reach the floor just below your shoulders.
Slowly walk out with your hands until the ball moves towards your toes. Only walk out as far as you are comfortable (either to your hips, knees, or ankles). Once you've reached your point of comfort, slowly walk back to the starting position, breathing steadily throughout.
Keep your core strong by not dropping your hips. Your body should be as straight as possible.
