How to do it
- Adjust the seat so your knees line up with the machine pivot.
- Set the thigh pad snug on your thighs just above your knees, with the ankle pad above your heels.
- Hold the side handles and start with your legs out, not locked.
- Curl your heels toward your hips as far as your knees bend.
- Pause briefly, then let the weight back slowly.
