Lying Leg Curl Machine

Knee flexion, machine, hamstrings

The lying leg curl machine has you lie face down and curl the heels toward the glutes against a roller pad. It isolates the hamstrings, with the calves helping to bend the knee. It suits anyone who wants stronger hamstrings beside squats and deadlifts, beginners included.

Setting up

  • Adjust the roller so it sits on the back of the lower legs, just above the heels.
  • Lie face down with the knees just off the edge of the pad, lined up with the machine's pivot.
  • Hold the front grips and press the hips into the pad.
  • Start with a light load you can curl with control.

How to do a lying leg curl

  1. Curl the heels up toward the glutes by bending the knees.
  2. Keep the hips pressed down as the roller rises.
  3. Pause when the knees are bent to about 90 degrees or more.
  4. Lower the roller slowly until the legs are nearly straight.

Breathing. Breathe out as you curl and breathe in as you lower.

Hamstrings

Calves

Common mistakes

  • Hips lifting off the pad. That lets the back help, so press the hips into the pad and hold the grips.
  • Swinging the weight up. Momentum skips the hamstrings, so curl smoothly and pause at the top.
  • Stopping halfway down. Half reps leave the stretch out, so lower until the legs are nearly straight.
