Exercise guide

Resistance Band Leg Curl

  • Beginner
  • Isolation
  • Rep-based
  • Lower legs
  • Upper legs

This unilateral isolation exercise targets the hamstrings through their full range of motion, using the progressive resistance of the band to maximize peak contraction. It effectively builds posterior chain strength and knee stability while providing constant tension throughout the movement.

Muscles worked

Primary

  • Hamstrings

Secondary

  • Glutes

Equipment

  • Resistance band

Setup

  1. Secure one end of a resistance band to a low, sturdy anchor point near the floor.
  2. Loop the other end around your right ankle and lie face down on the floor, positioned far enough away to create light tension in the band when your leg is straight.
  3. Extend your legs fully and rest your forehead on your hands to maintain a neutral spine.
  4. Engage your core and press your hips firmly into the floor.

How to do it

  1. Exhale as you curl your right heel toward your glutes in a smooth, controlled arc.
  2. Squeeze your hamstring forcefully at the top of the movement for a one-second pause.
  3. Inhale as you slowly lower your leg back to the starting position using a controlled 3-second eccentric tempo.
  4. Complete the prescribed repetitions for the right leg before switching the band to the left ankle.

Form checklist

  • Keep your pelvis glued to the floor; do not let your hips lift as you curl.
  • Maintain a flexed foot (toes toward the shin) to keep the tension on the hamstrings.
  • Ensure the movement occurs only at the knee joint without swinging the leg.
  • Keep your upper body relaxed to avoid unnecessary tension in the neck or lower back.

Pro tips

  • To maximize the mind-muscle connection, visualize pulling your heel toward your glute rather than just moving the band.
  • Intentionally press your quads into the floor to help stabilize the femur and isolate the hamstring more effectively.

Make it harder

  • Increase the distance from the anchor point to create higher tension at the start of the movement.
  • Incorporate a 3-5 second isometric hold at the peak of the contraction on every rep.
