How to do it
- Sit in the machine and align your knees with the machine's pivot point by adjusting the back pad.
- Hook your shins behind the roller pad with the pad just above the ankle joint, not on the foot.
- Grip the side handles, brace your core, and press your back firmly into the seat.
- Extend the knees smoothly until the legs are straight, driving the lever arm up with the quads.
- Squeeze hard at the top with toes pulled toward the shins, holding the contraction for a beat.
- Lower the lever slowly over 2 to 3 seconds back to the start, keeping tension on the quads throughout.
Common mistakes
- Loading too many plates and dropping the lever fast, which trains momentum instead of the quads.
- Cutting the range short on either end, which trains only the easy middle of the motion.
- Lifting the hips off the seat to muscle the lever up, shifting work away from the target.
- Hyperextending the knees at the top under heavy load, slamming the joint instead of stopping clean.
