Lever Seated Leg Curl Plate Loaded
- Beginner
- Isolation
- Rep-based
- Lower legs
- Upper legs
This exercise isolates the hamstrings and assists the gastrocnemius (calves) through knee flexion, using a plate-loaded leverage arm for consistent resistance. It is highly effective for building posterior chain thickness while providing a stable, seated position that protects the lower back.

Setup
- Sit on the machine with your back firmly against the backrest and adjust the seat so your knees align perfectly with the machine's pivot point.
- Position the padded lever arm so it rests comfortably against your lower Achilles tendon, just above your heels.
- Lower the lap pad snugly against your thighs to lock your hips in place and prevent them from lifting during the set.
- Grasp the side handles firmly to stabilize your torso and maintain a proud chest.
How to do it
- Exhale as you curl your legs downward toward the seat by flexing your knees in a smooth, powerful motion.
- Contract your hamstrings forcefully at the bottom of the movement, holding the peak contraction for one second.
- Inhale as you slowly return the weight to the starting position, resisting the load to maintain tension on the hamstrings.
- Follow a controlled tempo, taking roughly 2 seconds to curl down and 3 seconds to return up.
Form checklist
- Keep your lower back and glutes pressed firmly into the seat throughout the entire range of motion.
- Ensure your knees stay aligned with the machine's axis of rotation to prevent joint strain.
- Avoid pointing your toes excessively; keep your feet in a neutral or slightly flexed position.
- Do not allow the weight plates to touch the stack or the arm to rest at the top to keep constant tension.
Pro tips
- Think about pulling with your heels rather than your feet to enhance the mind-muscle connection with the hamstrings.
- To increase calf involvement, keep your ankles dorsiflexed (toes pointed toward your shins) throughout the movement.
- Maintain a slight 'internal' focus on the hamstrings, imagining them shortening as you pull the lever down.
Make it harder
- Add a 3-second pause at the point of maximum contraction (bottom) to eliminate momentum.
- Perform the eccentric (upward) phase with only one leg while using both legs for the concentric (downward) phase.
