Lever Lying Single Leg Curl
Lever Lying Single Leg Curl Exercise Description
The Lever Lying Single-Leg Curl trains knee flexion with the hips supported, emphasizing the hamstrings (biceps femoris, semitendinosus, semimembranosus). The gastrocnemius assists because it also crosses the knee. Performed one leg at a time, this variation promotes precise alignment and control while limiting momentum. You lie prone on a leg-curl machine, keep a neutral spine and level pelvis, and flex the working knee to bring the heel toward the glutes. Proper setup—knee aligned with the machine’s pivot and the roller pad positioned just above the back of the ankle—helps keep the motion centered at the knee. The goal is smooth, controlled reps through a comfortable range without lifting the hips, arching the low back, or rotating the leg.

How To Do The Lever Lying Single Leg Curl Exercise
‘- Adjust the machine so your knee aligns with the lever’s axis; set the roller pad just above your Achilles (low calf).
– Lie prone with chest and hips in contact with the bench; grip the handles for stability.
– Brace lightly, maintaining a neutral spine and level pelvis; keep both thighs on the pad.
– Start with the working leg straight but not locked; foot in line with the knee (neutral).
– Exhale and flex the knee, drawing the heel toward the glutes without lifting the hips or arching the low back.
– Pause briefly near end range while keeping the thigh down and the pelvis still.
– Inhale and lower the lever under control until the knee is nearly straight, avoiding knee lockout and weight-stack contact.
– Maintain neutral leg alignment (don’t let the knee drift inward or outward); keep movement slow and controlled.
– Switch legs and repeat with the same setup and cues.
Lever Lying Single Leg Curl Tips
‘- Align your knee directly with the machine’s pivot before starting each leg.
– Set the roller pad just above your Achilles so the force stays centered at the knee.
– Keep your chest and hips in contact with the bench and grip the handles for stability.
– Brace lightly to maintain a neutral spine and level pelvis, with both thighs on the pad.
– Start each rep with the working leg straight but not locked and the foot in line with the knee.
– Curl the heel toward your glutes without letting your hips lift or your low back arch.
– Pause briefly near the top while keeping the thigh down and pelvis still.
– Lower the weight under control, stopping just before your knee fully locks and before the stack touches.
– Maintain neutral leg alignment throughout—don’t let the knee drift inward or outward, and keep the rep slow and controlled.
Lever Lying Single Leg Curl Beginner Introduction
The Lever Lying Single-Leg Curl is a machine-based exercise that works one leg at a time while the body is supported on a bench. During this movement, the person lies face down on a leg-curl machine with the chest and hips resting on the padding and the lower leg placed under a roller near the ankle. As the knee bends against the resistance, the weight moves through a guided path, highlighting work in the back of the thigh, with help from the calf where it passes behind the knee.
Because only one leg moves at a time, this variation places a strong emphasis on even positioning and steady control. The reinforced support under the torso helps the action stay centered at the knee instead of turning into a swinging motion through the hips or lower back. The result is a slow, deliberate curl and release of the leg through a comfortable bend and straighten, with the pelvis and trunk staying settled against the bench throughout the set.
