Razor Curl Overview

The razor curl is a variation of the glute ham raise and an exercise used to strengthen the muscles of the hamstrings.

The razor curl is generally viewed as a way to progress to full glute ham raises.

Glute ham raise variations are a great alternative to the leg curl and an exercise that can help improve deadlift and squat strength.

Razor Curl Instructions

  1. Set up in a GHD with your knees bent, hips flexed, and torso parallel to the floor.
  2. Extend the legs while maintaining the torso position.
  3. Continue until your body is in a straight line and parallel to the floor.
  4. Pull yourself back to the starting position using your hamstrings.
  5. Repeat for the desired number of repetitions.

Razor Curl Tips

  1. You should feel this primarily through your glutes and hamstrings. If you’re getting a lower back pump then odds are, you’re dealing with a core/pelvis stability issue.
    • If you find that you struggle with keeping a neutral spine then you can regress to something such as valslide leg curls or eccentric only GHRs.
  2. Razor curls are typically used as a progression to GHRs so if you struggle to complete normal GHRs then you can use this variation which shortens the lever arm.
  3. Refrain from locking out your knees at the bottom of the movement to keep tension through your hamstrings.
