How to do it

  1. Adjust the seat so your knee lines up with the machine's pivot and the pad rests on your lower shin.
  2. Sit back, hold the handles, and place one shin behind the pad, letting the other leg hang relaxed.
  3. Straighten your working leg until the knee is fully extended and squeeze your quad at the top.
  4. Lower slowly under control, then switch legs.

Warm up first and pick a weight you can control through the whole movement. Stop if something hurts.
