The Nordic hamstring curl is a kneeling bodyweight exercise with the ankles pinned by a partner or a pad, lowering the body toward the floor to train the hamstrings through a long eccentric. Unlike a lying leg curl, where the hamstrings shorten against a stack, here they lengthen under your full torso weight and the lever gets longer the further you fall, so the hardest point is near the floor. Most lifters cannot pull themselves back up at first and use the hands to return. Sprinters and field athletes program it after the main lift on lower body days.
What Muscles Does the Nordic Hamstring Curl Work?
- Primary: Hamstrings (biceps femoris, semitendinosus, semimembranosus)
- Secondary: Gastrocnemius (calf), gluteus maximus
- Tertiary: Erector spinae, rectus abdominis, tibialis anterior
How Do You Set Up for the Nordic Hamstring Curl?
Kneel on a folded mat with your knees hip-width apart and your shins flat. Have a partner kneel behind you and press your heels down with both hands, or wedge your ankles under a loaded bar padded with a towel, so the heels cannot rise. Sit tall with your hips fully extended, thighs vertical, arms bent at your chest and hands ready to catch the floor. Squeeze your glutes before you start to lean.
How Do You Perform the Nordic Hamstring Curl?
- Lock your hips straight with your glutes tight, so your body is one line from knees to head.
- Lean forward from the knees, letting your torso fall slowly while your hamstrings brake the descent.
- Reach the point where you can no longer slow the fall, usually with the torso below 45 degrees, and let your hands take the floor.
- Pause for one count with your hips still straight and your chest a hand above the mat.
- Push lightly off the floor and pull with your hamstrings to bring your torso back over your knees.
- Return to the tall kneeling position with your hips extended, hands back at your chest, ready for the next rep.
What Are the Key Form Cues?
- Fall as one plank: keep a straight line from knees to shoulders so the hamstrings, not the hip flexors, control the lean.
- Push your heels into the anchor: driving the heels back into the partner's hands or the pad keeps the knees flexing against resistance.
- Think of pulling your heels toward your glutes on the way down, even though they cannot move.
- Keep your glutes squeezed so the hips never break backward.
- Use the hands only for the part you cannot control, then let go as soon as you can.
What Are the Most Common Mistakes?
- Falling through the last third: the hamstrings let go and the hands slam the floor, so the deepest range goes untrained; stop where you can still brake.
- Bending at the hips on the way down: the torso folds and the load shifts off the hamstrings onto the hip flexors; keep the hips locked open.
- Rushing the descent: a fast drop near full knee extension is where the biceps femoris strains, since the muscle is longest and under the most load; take at least three counts to the floor.
- Letting the heels lift from the anchor: the knees slide forward and the lever collapses; press the heels down through the whole rep.
- Pushing hard off the floor to return: the concentric disappears and the set becomes push-ups; push only as much as needed to let the hamstrings finish.
What Are the Best Nordic Hamstring Curl Variations?
- Band-assisted Nordic curl: a band around the chest anchored in front lifts some body weight, for lifters who cannot control the drop.
- Nordic curl with full concentric: pulling back up without hands, once the eccentric reaches the floor.
- Nordic curl with hips flexed: leaning from a hinged hip shifts emphasis to the hamstrings at the knee only.
- Single-leg Nordic curl: one heel anchored at a time, once the two-leg version is no longer hard.
- Lying Hamstrings Curl with Resistance Bands: the same knee flexion against a band, without the lever.
How Do You Progress the Nordic Hamstring Curl?
- Lower your torso one hand-width further before catching the floor once you control every rep to the same depth.
- Build from 3 to 8 reps per set at a fixed depth before going deeper.
- Add a set at a time, from 2 to 4, once the hamstrings recover between sessions without soreness.
- Slow the descent to five counts, or hold the lowest position for two counts, when depth cannot increase.
How Should You Program the Nordic Hamstring Curl?
Place the Nordic hamstring curl after your squat or deadlift on a lower body day, while the hamstrings are warm but not exhausted. Train it once or twice a week for 2 to 4 sets of 3 to 8 reps with 90 to 120 seconds of rest, since each rep is near maximal. Pair it with a Romanian deadlift so thehamstringsare loaded at the hip as well as the knee.
