Razor Curl

Which muscles does it train?

Equipment needed

How to perform it

For strength, 3 to 5 sets of 2 to 5 reps with 3 to 5 minutes of rest are common. For hypertrophy, use 3 to 4 sets of 6 to 10 reps with 2 to 3 minutes of rest.

Execution and technique cues

• Kneel on the pad with your lower thighs secured under the rollers and your hips flexed at 90 degrees.
• Keep your torso parallel to the floor and maintain a flat back as your starting position.
• Flex your knees to pull your body upward, keeping the 90-degree hip angle constant.
• Squeeze your hamstrings at the top of the movement before returning to the starting position under control.

Common mistakes

• Extending the hips during the ascent instead of keeping them flexed at 90 degrees.
• Using momentum or swinging the upper body to complete the repetition.
• Dropping down too quickly during the eccentric phase without controlling the descent.

Frequently asked questions

What is the main benefit of the razor curl over a standard glute-ham raise?

The razor curl keeps the hips in flexion, which increases the recruitment of the hamstrings at the knee joint while reducing glute involvement.

How do I scale the razor curl if it is too difficult?

You can place a resistance band around your chest attached to a point behind you, or use your hands to push off a support in front of you.
