Workout equipment

I was initially resistant to the exercise balls that I saw at the gym, but after seeing one exercise for the abs on television, I have begun to use an exercise ball for the ab roll.

Place your arms on the ball, parallel to one another. Pulling your belly button towards your spine and tightening your torso, slowly roll forward until your chest touches the ball. Keeping form, slowly pull your body back using your arms and abdominals. Don't collapse as you roll forward!
