Lever Lying Leg Curl
The Lever Lying Leg Curl is a machine exercise that isolates the back of the thighs, allowing focused strength work through knee bending.
Lever Lying Leg Curl
The Lever Lying Leg Curl is a machine-based exercise performed lying face down, with the lower legs moving against a fixed resistance arm. The supported position eliminates the need for balance and coordination, allowing each repetition to follow a consistent, repeatable path that keeps tension focused on the hamstrings.
Hamstring stiffness and extensibility directly affect performance in knee-flexion exercises like this one. Combining static and dynamic stretching before training can improve muscle-tendon unit compliance and support a fuller range of motion during curls (Takeuchi et al., 2024). The hips and upper body stay pinned to the bench, so the effort remains concentrated in the back of the thighs with minimal compensation from other areas.
This exercise fits well into strength and hypertrophy programs when the goal is direct hamstring work. Compared to bodyweight hamstring exercises like the Nordic curl, which generate very high eccentric forces (Burrows et al., 2020), the lying leg curl offers more precise load control and a lower injury threshold, making it suitable for beginners and experienced lifters alike.

Technique and form
How to perform the Lever Lying Leg Curl
- Lie face down on the machine and position the back of your ankles under the roller pads, adjusting them to align with your ankles.
- Grasp the handles or the sides of the bench for stability, keeping your hips pressed firmly against the pad and your spine in a neutral position.
- Exhale and contract your hamstrings to curl the weight up by bending your knees, moving in a controlled arc until your legs form approximately a 90-degree angle.
- Maintain tension in your core and keep your hips pressed down on the bench throughout the movement to prevent your lower back from arching.
- Hold the contracted position at the top for 1-2 seconds, focusing on squeezing your hamstrings.
- Inhale as you slowly lower the weight back to the starting position, controlling the descent without letting the weight stack touch down completely.
- Keep your feet relaxed with toes pointed forward or slightly inward, avoiding unnecessary tension in your calves.
- Repeat for the prescribed number of repetitions, maintaining a steady tempo and focusing on hamstring engagement rather than momentum.
Important information
- Adjust the machine before starting to ensure the pivot point aligns with your knee joint and the leg pad sits just above your heels.
- Avoid lifting your hips off the bench during the curl—this compromises form and shifts work to your lower back.
- Keep the movement smooth and controlled rather than using momentum, especially on the lowering phase.
- If you experience knee pain, try adjusting your foot position or reduce the range of motion until you find a comfortable position.
Common Mistakes: Lever Lying Leg Curl
Benefits of the Lever Lying Leg Curl
Muscles Worked: Lever Lying Leg Curl
The Lever Lying Leg Curl is an isolation exercise that focuses your effort on the back of your thighs (hamstrings). Here's a breakdown of every muscle involved.
Primary muscles
Hamstrings — Your back of your thighs (hamstrings) control the lowering phase and assist the hips. These are the main muscle doing the heavy lifting during the Lever Lying Leg Curl.
Secondary muscles
Glutes — Your glute muscles generate hip power and keep your pelvis stable. While not the main focus, these muscles play an important supporting role.
The Lever Lying Leg Curl primarily works 1 muscle with 1 supporting muscle assisting the movement.

FAQ - Lever Lying Leg Curl
The Lever Lying Leg Curl primarily targets the hamstring muscle group (semitendinosus, semimembranosus, and biceps femoris) while also engaging the glutes as secondary movers. This isolation exercise also minimally activates the calves and lower back as stabilizers.
Position yourself face-down on the machine with the pad just below your calves and your knees aligned with the pivot point. Keep your hips pressed into the bench throughout the movement and avoid lifting them as you curl the weight. Focus on contracting your hamstrings to initiate the movement rather than swinging or using momentum.
For optimal results, incorporate Lever Lying Leg Curls 1-2 times weekly, allowing 48-72 hours between sessions for hamstring recovery. Place this exercise on your leg or pull days, typically performing 3-4 sets of 8-12 repetitions for hypertrophy or 4-6 sets of 6-8 reps for strength development.
The most common mistake is rushing through the movement without focusing on the quality of the rolling motion. Other errors include using excessive tension rather than controlled movement, and failing to achieve full range of motion through all three planes of shoulder movement (flexion, depression, and retraction).
Yes, most people with mild to moderate lower back issues can perform this exercise safely since the prone position with proper hip alignment provides good lower back support. However, avoid hyperextending your lower back during the movement, and if you experience any pain, consider alternatives like seated leg curls or stability ball hamstring curls.
