Machine Lying Leg Curl
MachineStrength
The Machine Lying Leg Curl is a strength exercise performed on a dedicated leg curl machine where you lie face down and curl your heels toward your glutes by flexing the knees. It primarily targets the posterior thighs, including the hamstrings, to build strength, size, and endurance in the back of the legs while improving knee stability. Ideal for gym-goers seeking isolated hamstring development, it requires no additional bodyweight beyond machine resistance and suits beginners to advanced lifters focusing on lower-body balance.
How to Perform Machine Lying Leg Curl
- 1Adjust the machine so the leg pad rests just above your heels, and set the weight to a challenging but manageable load.
- 2Lie face down (prone) on the machine bench with your knees aligned with or just off the edge of the pivot point.
- 3Position your ankles under the leg pad, feet flexed (toes pointing toward shins), and grasp the handles for stability.
- 4Engage your core and keep hips pressed down into the bench to avoid arching your lower back.
- 5Inhale to prepare, then exhale as you bend your knees to curl the pad toward your glutes, squeezing your hamstrings at the top.
- 6Pause briefly at peak contraction, then inhale as you slowly lower the pad back to full extension without locking knees.
- 7Repeat for desired reps (e.g., 10-15 per set), then carefully exit the machine.
- 8Key form tips: Keep movement slow and controlled (2-3 seconds up, 3-4 seconds down); avoid swinging or using momentum; ensure full range without knee hyperextension. Common mistakes: Lifting hips off bench or partial reps.
