The lying leg curl trains knee flexion—the other major function of your hamstrings besides hip extension. This machine isolates your hamstrings by removing hip movement, allowing you to focus entirely on curling your heels toward your glutes. The prone position keeps your hamstrings in a shortened position, creating a different stimulus than hip hinge movements.
Keep your hips pressed into the pad throughout—lifting your hips shifts work to your glutes and lower back. Point your toes slightly down to reduce calf involvement and maximize hamstring contraction. Squeeze hard at the top.
Lying leg curls train knee flexion with the hip extended, working the hamstrings in a shortened position compared to seated curls. The prone position prevents hip flexor involvement. The short head of the biceps femoris (which only crosses the knee) contributes more in this position.

Lie face down on leg curl machine.
Position pad just above heels.
Curl heels toward glutes by flexing knees.
Squeeze hamstrings at peak contraction.
Lower slowly under control.
Repeat without momentum.
Dont lift hips off pad.
Point toes down for more hamstring focus.
Control the negative.
Program lying leg curls after hip hinge movements like RDLs to complete your hamstring training by adding knee flexion work. Use them 2-3 times per week when hamstring development is a priority. They pair well with any hip hinge movement since each trains a different hamstring function.
Lifting hips during curl.
Using too much weight.
Partial range of motion.
All levels seeking direct hamstring isolation. Those using the seated variation may include lying curls for variety since the position creates a different strength curve.
Recommendation: 3-4 sets of 10-12 reps. Rest 60 seconds.

Start My $19 WeekThe lying leg curl loads both hamstrings at once, which hides side-to-side imbalances. The standing leg curl trains each leg independently so a weaker hamstring cannot hide behind the stronger one. Use lying curls for maximum load and volume; switch to standing curls when you notice one leg finishing reps earlier than the other.
