About

A cable or machine exercise curling the heel toward the buttocks while standing, isolating the hamstrings through knee flexion against resistance.

Instructions

Step-by-step technique

01

Secure the ankle attachment

Attach the ankle cuff to the cable pulley set at the lowest possible position. Secure the cuff firmly just above your ankle joint on your working leg, ensuring it is tight enough to prevent slipping during the movement.

Check the clasp
02

Establish your balanced position

Stand facing the cable anchor point while balancing on your stationary leg. Keep a slight bend in your standing knee to maintain stability and engage your core muscles to ensure your torso remains tall and upright.

Core tight, chest tall
03

Curl the weight upward

Initiate the movement by flexing your knee, pulling your heel directly toward your glutes. Maintain a steady tempo and ensure that only your lower leg moves, keeping your thighs parallel to each other throughout the repetition.

Squeeze the hamstring
04

Control the eccentric phase

Slowly extend your knee to return your foot to the starting position without letting the weight stack touch. Focus on resisting the pull of the cable to maximize muscle tension and strength gains during this lowering phase.

Slow and steady
05

Complete all targeted repetitions

Perform the desired number of repetitions on one side before switching the cable cuff to your opposite ankle. Maintain consistent form and tension on both legs to ensure balanced development of the posterior chain.

Maintain your balance

Common mistakes

What goes wrong — and why

Mistake

Hip flexing during the curl

Allowing the hip to flex forward engages the hip flexors to assist.

Keep the hip in neutral extension with the thigh pointing straight down.

Mistake

Using momentum to kick up

Swinging the foot reduces hamstring isolation.

Curl the heel upward slowly over 2 seconds and lower over 3 seconds.

Mistake

Locking the knee on the working leg

An excessively rigid standing leg transfers tension to the knee.

Allow a soft bend in the standing knee for stability throughout.

Adaptations for every level

Regression

Prone Leg Curl Machine

Use a prone leg curl machine for a supported isolation of the hamstrings.

Variation

Single-Leg Swiss Ball Curl

Lie on the back and curl one leg on a stability ball for instability challenge.

Progression

Nordic Hamstring Curl

A bilateral eccentric hamstring exercise providing far greater strength development.
