Nordic Curl Progression

The Nordic curl (Nordic hamstring curl / natural glute-ham raise) trains the hamstrings in their knee-flexion role through a powerful eccentric. Kneel with the ankles anchored (under a sturdy object or held by a partner), hips straight, and lower the torso toward the floor as slowly as possible, resisting with the hamstrings; push off the hands at the bottom and use them to assist the return. Because the hamstrings are far stronger eccentrically than concentrically, the movement is trained mainly as a slow negative (movement-speed / tempo).

Progression, from easiest to hardest:

1. Assisted / band-assisted negatives — large hand or band assistance, short lowering range.
2. Long-lever negatives — lower farther under control before the hands catch you.
3. Full Nordic negative — control the entire descent to the floor.
4. Full Nordic curl — lower and then pull back up with minimal or no hand assistance (very advanced).

It is the bodyweight counterpart of the machine leg-curl and the glute-ham-developer raise, and complements the hip-extension hip-hinge-bridge-progression. The hamstrings are highly susceptible to strain here — warm up thoroughly and add range slowly.

• Kneeling, ankles anchored; lower the torso forward slowly (eccentric hamstring work).
• Hamstrings are stronger eccentrically — trained mainly as slow negatives.
• Progress: assisted negatives → longer-range negatives → full negative → full curl up.
• Bodyweight counterpart to leg curls / glute-ham raises; high strain risk — progress slowly.

• hip-hinge-bridge-progression — complementary hip-extension hamstring work.
• leg-curl / glute-ham-developer — machine analogues.
• hamstrings — prime mover.
• movement-speed / tempo — the eccentric emphasis.
