Core Strength Exercise #2: Ab Roll

Kneeling on a mat or other soft surface with a Swiss ball in front of you, place your arms parallel to one another on the ball. Pull your belly button towards your spine and tighten your torso, and slowly roll forward until your chest touches the ball. Keeping this tight and aligned form, slowly pull your body back using your arms and abdominals. Try not to collapse as you roll forward. Repeat ten to twelve times.
