Nordic Hamstring Curl
How to Do a Nordic Hamstring Curl
Kneel on a padded surface with the knees around hip width and secure the ankles under a stable anchor or have a partner hold them firmly.
Brace the core and squeeze the glutes so the torso, hips, and thighs stay aligned rather than folding at the waist.
Begin leaning forward from the knees while resisting the descent with the hamstrings.
Lower as slowly as possible through the range you can control without the hips dropping or piking.
When you can no longer control the descent, place the hands on the floor to catch your body safely.
Use the hands, a band, or a box for enough assistance to return to the kneeling start if you cannot perform the full concentric phase.
Reset the body line before each repetition; stop the set when the descent becomes uncontrolled.
Form Check & Technique
DO THIS (Technique Tips)
- Pad the knees.
- Secure the ankles firmly.
- Keep hips extended and ribs controlled.
- Lower as slowly as possible.
- Use band or box assistance early.
- Progress range before adding load.
- Use low-quality fatigue as the signal to stop.
AVOID THIS (Common Mistakes)
- Piking at the Hips — Fix: squeeze the glutes and maintain a straight line from knees through shoulders.
- Dropping Immediately — Fix: use a band, box, or shorter range so you can actively resist the descent.
- Using an Unstable Foot Anchor — Fix: secure the ankles before starting and test the setup with a partial rep.
- Trying Full Reps Before You Can Control Eccentrics — Fix: build strength with assisted and negative-only progressions.
- Overusing the Hands — Fix: use only enough push from the floor to return safely; keep the hamstrings responsible for the controlled phase.
- Chasing High Reps With Poor Form — Fix: end the set when the body line or lowering speed breaks down.
About Nordic Hamstring Curl
The Nordic hamstring curl is a bodyweight knee-flexion exercise performed from a kneeling position with the ankles securely anchored. You keep the body aligned from knees to shoulders while resisting the forward fall with the hamstrings. Most people begin with partial-range, band-assisted, box-assisted, or eccentric-only repetitions before progressing to a full unassisted return.
Nordic Hamstring Curl Muscles Worked
The hamstrings produce high eccentric knee-flexor force as the body lowers.
- The glutes and trunk help keep the hips and spine aligned, while the gastrocnemius can assist knee flexion because it also crosses the knee joint.
Sets & Reps Guidance
Technique / Learning
Technique: 2–4 sets of 2–5 short-range or eccentric-only reps with hand, box, or band assistance.
Strength Focus
Strength: 3–5 sets of 3–6 controlled eccentric or full reps with long rest between sets.
Muscle Growth (Hypertrophy)
Muscle growth: 3–4 sets of 5–10 assisted or full reps, using enough assistance to keep every repetition controlled.

Nordic Curl Benefits for Eccentric Hamstring Strength
Nordics place a large eccentric demand on the knee flexors as you resist the forward fall. Training studies and reviews report improvements in eccentric hamstring strength and muscle architecture when Nordic work is programmed consistently.
Nordic Curls and Hamstring Injury Prevention
Systematic reviews have found lower hamstring-injury rates in sports programs that include Nordic hamstring exercise, with several meta-analyses reporting an injury-rate reduction around one half. That evidence applies to structured prevention programs; it does not mean a few Nordic curls guarantee that an individual will avoid injury.
Nordic Curl Progression: Rocking to Full Reps
Physiopedia outlines a useful progression: short rocking reps, assisted reps with a box or band, eccentric-only lowers with a hand catch, then full repetitions. Choose the level where you can keep the hips extended and control the descent.
Band-Assisted Nordic Curl
A band placed around the torso and anchored behind you reduces the effective bodyweight as you move toward the floor. Use enough assistance to keep the body line intact, then gradually use a lighter band as strength improves.
Nordic Curl vs Leg Curl Machine
Both train knee flexion, but a machine curl lets you select the resistance precisely and usually supports the rest of the body. The Nordic curl uses a long body lever and emphasizes eccentric control, making it much more difficult relative to bodyweight.
Nordic Curl vs Glute-Ham Raise
The Nordic curl keeps the body relatively straight from knees to shoulders and primarily challenges knee-flexor strength through a long lever. A glute-ham raise uses a GHD and can combine knee flexion with hip-extension mechanics through a different range.
How Many Nordic Curls Should You Do?
Nordics are demanding, so quality matters more than high rep counts.
- Beginners can use low-rep eccentric or assisted sets, while stronger lifters can gradually build toward controlled full repetitions.
- Stop before hip position or eccentric control deteriorates.
