Adjust the height of the platform so that your hips are aligned with the pivot point of the machine. Then position the pad 45 degrees on the opposite side you will be pushing towards. Standing sideways, place your quad against the pad.
Drive your knee upwards in a smooth motion until your knee is roughly at hip level, then slowly return down the same path til your knees are next to each other. Use the grips and your core to maintain a steady torso throughout. Keep your leg in a fixed bend for the movement. Repeat for the desired repetitions then switch sides.
Avoid moving your torso too much or twisting during the movement.
