Abdominal Crunch
■ Lying on your back, with the knees bent, and your arms folded across your chest or hands
behind your head, slowly roll your shoulders away from the floor until a strong contraction
is felt in the abdominal.
■ Return to the starting position under control and repeat for the prescribed number
of repetitions.
■ Remember to maintain a neutral spine, exhale on the exertion, and avoid poking the chin.
