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.
Razor Curl Instructions
- Set up in a GHD with your knees bent, hips flexed, and torso parallel to the floor.
- Extend the legs while maintaining the torso position.
- Continue until your body is in a straight line and parallel to the floor.
- Pull yourself back to the starting position using your hamstrings.
- Repeat for the desired number of repetitions.
Razor Curl Tips
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.
- 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.
- Refrain from locking out your knees at the bottom of the movement to keep tension through your hamstrings.
