What is a prone leg curl?
A prone leg curl is a hamstring exercise performed face down on a machine. You place the back of your ankles under or against a padded lever, then bend your knees to bring your heels toward your glutes. The machine adds resistance so the hamstrings have to work through the full curl and lowering phase.
How to set up a prone leg curl machine
- Adjust the machine so your knees sit close to the edge of the bench or just before the pivot point.
- Place the pad just above your ankles, not on the Achilles or calves.
- Grip the handles and press your hips lightly into the bench.
- Start with a light weight so you can learn the path before adding load.
How to perform the rep
Curl your heels toward your glutes without lifting your hips off the bench. Pause briefly when your knees are bent, then lower the weight slowly for 2–3 seconds. Do not let the weight stack slam down, because the lowering phase is where the hamstrings do a lot of useful work.
Common prone leg curl mistakes
- Using too much weight and swinging the legs.
- Lifting the hips or arching the lower back.
- Placing the pad too high behind the knees or too low near the heels.
- Cutting the range of motion short instead of curling through a full but comfortable path.
How to add prone leg curls to leg day
Use prone leg curls after squats, leg press, lunges, or Romanian deadlifts. Start with 2–3 sets of 10–15 reps, rest 60–90 seconds, and add weight only when you can keep your hips down and your reps smooth.
