Instructions
Lie prone on the bench, with your knees just over the edge and the bottom of your calf muscles placed under the padded lever. Grasp the handles in front of you. Raise your torso off the bench slightly, and push your hips in to the bench. Raise the padded lever until it touches the back of your thighs. Lower the lever until your knees are straight.
Tips
Point your toes to work your hamstrings more. Your hips should not move from the bench, if they do, the weight you are using is too heavy.
