How to Do Lying Leg Curls: Form, Muscles, and Tips

Master the lying leg curl with our professional guide. Learn proper machine setup, step-by-step form, and mistakes to avoid for stronger hamstrings.

How to Perform

  1. Adjust the machine lever so the padded roller rests just above your heels at the base of your Achilles tendon.
  2. Lie face down on the bench and align your knees with the machine's pivot point to ensure proper joint mechanics.
  3. Grasp the handles firmly and press your hips firmly into the pad to prevent your lower back from arching.
  4. Exhale as you curl your legs upward toward your glutes in a smooth, controlled arc.
  5. Squeeze your hamstrings at the peak of the movement for one second without letting your hips lift off the bench.
  6. Lower the weight slowly to the starting position until your legs are fully extended but not locked out.

Common Mistakes

  • Lifting the hips off the pad to use momentum
  • Setting the ankle pad too high on the calves
  • Using a rapid, uncontrolled tempo on the descent
  • Pointing the toes excessively during the contraction
