Exercise
Nordic Curl
The Nordic curl is one of the hardest unloaded movements in the gym. It trains the hamstrings eccentrically at long muscle lengths — exactly where most hamstring strains happen.

The movement
The Nordic curl begins with the lifter kneeling on a padded surface, ankles anchored by a partner, dedicated Nordic bench, or a loaded barbell against a wall. From a fully upright kneeling position, the lifter lowers the torso forward toward the floor while keeping the hips extended. The hamstrings eccentrically control the descent. Most lifters cannot return to the top under their own power initially — a push off the floor is acceptable during the learning phase.
The movement has robust research support for reducing hamstring strain injury in athletes. The protective effect comes specifically from the eccentric overload at long muscle lengths, a load pattern that barbell RDLs and leg curls do not replicate to the same degree. Sprinters, soccer players, and sprint-dominant sport athletes use Nordics as an injury-prevention tool as much as a strength tool.
Volume is low relative to typical hamstring work. Three sets of three to five reps, performed once or twice per week, is plenty. Eccentric-only variants — descend under control, push back up to the start — are a valid scaling option while strength is being built.
Technique
Form cues
- Keep the hips extended — do not let them break forward and turn the movement into a hinge
- Lower slowly; three to five seconds down is typical
- Brace the core throughout — trunk neutral, no sagging or arching
- Catch yourself with the hands only when the hamstrings cannot hold the position any longer
Avoid
Common mistakes
- Breaking at the hips — lowering by folding forward rather than controlling with the hamstrings
- Dropping through the mid-range — the eccentric must stay slow and controlled, especially past 45 degrees
- Training Nordics at high volume — the eccentric demand produces significant soreness; three hard sets a week is a lot
