The Nordic Hamstring Curl: Building Injury-Resistant Legs

The Nordic hamstring curl is one of the most effective bodyweight exercises for the hamstrings, and one of the most neglected. Research consistently shows it reduces hamstring injury rates in athletes. Here's why and how to do it.

The movement: kneel with feet anchored (under a couch, door bottom, or partner holding), lower your body toward the floor by extending at the knee, controlling the descent entirely with the hamstrings. Return using hands to push from the floor.

The eccentric is the training stimulus. The muscle is lengthening under load as you lower yourself. This is the loading pattern associated with hamstring strain prevention — the hamstrings in gait are loaded eccentrically at the end of the swing phase.

Progression: band-assisted negatives (band attached at chest level provides progressive assistance at the hardest point) → unassisted negatives → full Nordic with assisted concentric → full Nordic.

Start with 2 sets of 3-5 and build slowly. The first time you attempt these with any significant volume, you will be sore for 3-4 days. The adaptation is real but the initial load is significant.
