Nobody walks into the gym, sets up the Nordic curl station, and thinks "great, glute day." They're too busy thinking "great, I'm about to fall face-first into the floor."
And that's fair. The Nordic curl โ also called the natural leg curl or Nordic hamstring curl โ is genuinely one of the hardest bodyweight movements in existence. It earns its reputation as a hamstring destroyer. But calling it just a hamstring exercise is like calling a RDL just a lower back stretch. Technically defensible. Practically incomplete.
Your glutes are doing serious work during the Nordic curl, and most people are leaving that on the table because they've filed the exercise under "not for me" or "hamstrings only" and moved on.
Let's fix that.
What Actually Happens During a Nordic Curl
Here's a quick anatomy refresher, because the mechanism matters.
You start kneeling, feet anchored, body upright. You lower yourself toward the floor under control โ as slowly as humanly possible, which will never feel slow enough โ and then either catch yourself, use your hands to push back up, or pray. The hamstrings are working isometrically at the top and eccentrically throughout the descent, fighting gravity to keep you from becoming a pancake.
But here's what's also happening: your glutes are contracting hard to maintain hip extension and keep your body in that long, straight line from knee to shoulder. The moment your hips break โ the moment your butt shoots back to "save" you โ you've shifted the load away from both the hamstrings and the glutes and onto a compromised lumbar position that's doing nobody any favors.
A properly executed Nordic curl requires your glutes to stay engaged from start to finish. They're not the star of the show, but they're absolutely in the cast.
Good to know
The Nordic curl loads the hamstrings at long muscle lengths โ near full hip extension and knee flexion simultaneously. This kind of lengthened-state loading is associated with greater muscle growth stimulus, which is part of why it's so brutally effective (and brutal).
The Eccentric Angle โ And Why Your Glutes Care
Eccentric training is having a well-deserved moment in exercise science circles. Research consistently shows that loading muscles through their lengthening phase produces significant hypertrophy stimulus, sometimes more than traditional concentric-focused training. The Nordic curl is one of the most eccentric-loaded movements you can do without a machine.
Your glutes don't escape this. As you descend, the glutes are lengthening under load alongside the hamstrings. The glute-ham tie-in โ that lower sweep of the glute where it blends into the hamstring โ gets meaningful stimulus here that's hard to replicate with hip thrusts or even RDLs.
If you've been frustrated that your lower glutes won't fill out, and you've already read every article about hip extension range of motion and still feel like something's missing, the Nordic curl might genuinely be part of the answer.
โThe Nordic curl does more for your glute-ham tie-in than any amount of cable kickbacks, and if your program doesn't include some form of eccentric hamstring work, you don't actually have a complete glute program.โ
Fight me on this"But I Can't Do a Nordic Curl"
Good. Neither could most people the first time they tried.
The Nordic curl has one of the steeper learning curves of any bodyweight exercise because there's no partial version that feels remotely manageable at first. You either control the descent or you don't. Most people don't.
The solution is to start where you are, not where you wish you were.
Nordic Curl Progressions
1. Assisted Nordics with a band Loop a resistance band from something overhead and hold it in front of you as you descend. The band provides assistance at the bottom where you're weakest. This lets you feel the movement pattern without face-planting immediately.
2. Eccentric-only with a push Lower yourself as slowly as possible, catch yourself with your hands, push back up to the start. You're skipping the concentric entirely. This is the most common beginner approach and it works โ the eccentric is where most of the training stimulus lives anyway.
3. Partial range Nordics Only lower yourself to 30-45 degrees before returning. Not glamorous, but it builds the strength to eventually go further.
4. Full Nordic curl The real thing. Expect this to take weeks to months to reach depending on your current posterior chain strength. That timeline is normal.
Pro tip
If you're setting up at home, your feet can be anchored under a heavy barbell, a couch, or any fixed object at floor level. You don't need specialized equipment to start building Nordic curl strength โ just something that won't move and a mat for your knees.
How to Program It Without Wrecking Yourself
The Nordic curl produces significant delayed onset muscle soreness, especially in the early stages. This is not a movement you add to your program the week before a race, a vacation, or any event where you'd like to walk normally.
A reasonable starting point:
- 2 sets of 3โ5 reps, eccentric-only โ if you're new to the movement
- 2โ3 sets of 5โ8 reps โ once you've built tolerance
- Program it once per week to start; twice per week once your hamstrings stop filing formal complaints
It pairs well with a hip-thrust-heavy glute day because the hip thrust loads the glutes concentrically at short range while the Nordic loads the entire posterior chain at longer lengths. Together, they cover territory neither movement reaches alone.
โHip thrusts + Nordic curls cover the full length-tension curve of your posterior chain. That's the combination most people's programs are missing.โTweet this
The Injury Prevention Bonus You Didn't Ask For But Need
Here's the part that isn't sexy but matters: the Nordic curl is one of the most evidence-supported exercises for reducing hamstring strain injury. Research consistently shows that athletes who include Nordic curls in their training experience meaningfully fewer hamstring injuries than those who don't.
This isn't just athlete-relevant. Anyone who sprints, plays recreational sports, or simply wants their hamstrings to work correctly for the next several decades has skin in this game. Hamstring strength at long muscle lengths โ which is exactly what the Nordic curl builds โ is a weak point for most people, not because they're lazy, but because traditional training (leg curls, Romanian deadlifts) loads the hamstring in a relatively short position compared to maximal stretch.
Strong posterior chain. Fewer injuries. Better glute-ham tie-in. There's no bad outcome here.
The Setup That Makes This Easier
Your knees will thank you for a decent pad. The Nordic curl is hard enough without adding "concrete knees" to the experience.

Where This Fits in the Bigger Picture
The Nordic curl isn't going to replace your hip thrusts, your RDLs, or your split squats. It's not trying to. It occupies a specific and underrepresented niche in most glute programs: high-intensity eccentric loading of the posterior chain at lengthened positions.
Most people train the glutes concentrically, in a shortened to mid-range position, and wonder why certain parts of the muscle don't respond the way they want. The Nordic curl doesn't solve everything, but it fills a gap that a lot of carefully constructed programs are quietly missing.
The exercise is hard, the setup is low-tech, and the payoff โ for strength, for aesthetics, for long-term resilience โ is disproportionately high for something you can do on a mat in your living room.
Start with the eccentric-only version. Do it badly at first. Do it less badly next week. Give it a month before you pass judgment.
Your posterior chain will catch up. Your face will stay off the floor. Probably.
