Nordic hamstring curl for injury prevention

A bodyweight eccentric exercise that dramatically cuts hamstring strain risk.

Why it works

The Nordic curl forces the hamstrings to decelerate the tibia as the body falls forward — a pure eccentric load at long muscle lengths. This shifts the angle of peak torque to a longer muscle length, which is mechanically protective because most hamstring strains occur during the late swing phase when the muscle is long and producing force. Nordics build eccentric strength and fascicle length precisely where strains happen.

How to do it

1. Kneel on a padded surface with feet anchored (under a bar, by a partner, or in a Nordic bench).
2. Cross arms at chest and lower your body toward the floor as slowly as possible — aim for 3–5 seconds.
3. Use your hands to catch yourself at the bottom and push back to the start.
4. Begin with 2–3 controlled reps per set, 2 sessions per week; add reps as strength builds over weeks.

Evidence

Multiple randomized trials and meta-analyses find the Nordic hamstring curl reduces hamstring strain rates in team-sport athletes by roughly 50 % when integrated into warm-up programs. (rct)

Evidence is strongest in team sports (football, soccer); transfer to recreational athletes is plausible but less directly studied. Very sore initially — start with low volume.

Common mistake

Lowering too fast (a controlled fall instead of a slow eccentric), which turns a training stimulus into a collision. The slow descent is the entire point.
