Lever Lying Single Leg Curl
Lever Lying Single Leg Curl Exercise Description
The Lever Lying Single Leg Curl isolates knee flexion with the hamstrings as the prime movers (biceps femoris, semitendinosus, semimembranosus), with assistance from the gastrocnemius. Performing it one leg at a time improves focus, control, and helps identify side-to-side differences. The prone position and leverage machine provide a fixed axis for the knee, encouraging efficient force application while keeping the pelvis stable and the spine neutral. Proper setup and alignment allow a large, controlled range of motion without stressing the lower back. Keep the hips pressed to the pad and avoid trunk movement so the hamstrings perform the work through the knee.

How To Do The Lever Lying Single Leg Curl Exercise
‘- Adjust the machine so the roller pad rests just above the heel on the working leg; set any range limiter to allow near-full knee extension without locking.
– Align the machine’s pivot with the working knee’s joint axis (roughly at the lateral femoral epicondyle).
– Lie prone, chest and hips on the pad; grip the handles. Place the working ankle under the roller; keep the nonworking leg clear.
– Brace lightly and maintain a neutral spine and neck; square the hips and press both hip bones into the pad.
– Start with the working knee nearly straight; keep the ankle neutral or slightly plantarflexed to reduce calf involvement.
– Flex the knee to curl the pad toward the glutes; keep the thigh on the pad and avoid lifting the hip or rotating the leg.
– Stop when you reach a strong contraction without the pelvis lifting (about 90–120 degrees of knee flexion).
– Lower under control to the start, stopping just short of knee lockout.
– Keep the knee and toes pointing straight ahead; avoid turning the foot in or out.
– Use smooth, controlled motions and consistent pad contact; switch legs and repeat.
Lever Lying Single Leg Curl Tips
‘- Set the roller pad just above your heel on the working leg.
– Align the machine’s pivot point with the working knee’s joint axis.
– Lie prone with chest and hips firmly on the pad and grip the handles.
– Press both hip bones into the pad to keep the pelvis stable and the spine neutral.
– Start each rep with the working knee nearly straight, stopping just short of lockout.
– Keep the ankle neutral or slightly plantarflexed to reduce calf involvement.
– Curl by flexing the knee while keeping the thigh on the pad and the hip from lifting.
– Stop the curl when you feel a strong hamstring contraction without the pelvis lifting.
– Lower the weight under control and maintain smooth, consistent pad contact.
– Keep the knee and toes pointing straight ahead; avoid turning the foot in or out.
Lever Lying Single Leg Curl Beginner Introduction
The Lever Lying Single Leg Curl is a machine-based lower-body exercise centered on bending the knee against resistance while lying face down. Using a leverage-style leg curl machine, the working leg moves the roller by drawing the lower leg toward the glutes, with the body supported on a padded bench. This setup directs effort mainly into the hamstrings, with some help from the calves, while the rest of the body remains relatively still.
Because only one leg works at a time, the movement highlights imbalances between sides and encourages careful, deliberate control. The fixed path of the lever guides the knee through a clear arc, helping align the joint with the machine’s pivot for efficient force transfer. With the chest and hips resting on the pad and the spine in a natural position, the hamstrings can move through a broad, steady range of motion with minimal involvement from the lower back, emphasizing tension around the back of the thigh.
