Reverse Hyperextension

Lie on a hyperextension bench or swiss ball so that your arms are at the end of the bench where your feet normally go. Place your body so that your abdomen is resting on the bench or ball and your hips are completely off of it. Keep your legs together and straight, with your body forming a straight line.

Slowly lower your legs to the floor.

Pause, then lift your hips and thighs as high as you can.
