Each machine may vary, place one knee on the pad and the other leg will be straight. Lean forward and grab the handles, make sure your leg is fully stretched. Begin by curling your leg up, making sure your knee and upper leg is pressed against the pad, feel your hamstrings fully contract, pause and slowly return to the starting position. Finish your reps, and push the pad over to the opposite side and repeat.
