Crunch 510 Reps

Lie on your back, your knees bent and feet on the ground. Keep your knees slightly apart.

Perform a crunch by exhaling and tightening your abdominals.

This will bring your upper body off the ground... at about a 45 degree angle.

Allow your abdominals to perform the exercise.

Fold your arms across your chest, hold at the sides of your head or hold your arms above your head.
