Natural Glute Ham Raise
Also works: Calves · Glutes · Lower Back
Kneeling with your ankles anchored, you lower your torso toward the floor and pull yourself back up using nothing but the hamstrings. Improvised on a lat pulldown knee pad or a preacher bench, it is the hardest bodyweight hamstring movement most gyms can produce and one almost nobody can do a clean rep of on the first try.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Wedge your ankles under a fixed pad — a lat pulldown knee pad or the ankle rollers of a preacher bench — and check it will not slide before you trust it with your bodyweight.
- Kneel on something soft. Bare knees on a metal seat will end the set before your hamstrings do.
- Set your knees roughly hip-width and your shins flat along the surface.
- Squeeze your glutes and brace your abs so your hips, knees and shoulders form one straight line from the start.
- Put a box, a bench or your hands where you can reach them at the bottom — you will need them on the first sessions.
Every rep
Breathing & tempo — One breath per rep: inhale and brace at the top, hold through the descent, exhale as you pass the sticking point on the way up. Four to six seconds down, as fast as you can manage up.
Before you load it
- Test the improvised anchor with a hard tug before your first rep. A lat pulldown pad that lifts at 45 degrees drops you face-first from waist height.
- Set a landing before you start: hands ready in front of you or a mat under your chest. Catching yourself is part of the rep, not a bailout.
Sets, reps & load
Where to start, and what to change when it stops being hard.
Bodyweight is already close to the ceiling here. Start with assistance — a band anchored above you, hands on a box in front, or a partner's palms under your chest — and remove it a little at a time. When you can complete five unassisted reps with the hips locked straight, progress by slowing the descent to six seconds or holding a small plate to your chest, never by adding reps.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Squeeze the glutes hard before you start and think about pushing your hips forward toward the floor the whole descent. If the hinge appears anyway, stop the set at the last straight-line rep.
Count out loud on the descent. When you can no longer make four seconds, use a band around your chest anchored overhead, or a partner's hands, to unload the bottom half.
Test it with a hard tug before you commit. A pad that pops loose at 45 degrees drops your face onto the floor with nothing to catch you.
Cap the set at eight and end it the rep after the descent turns from controlled into falling. A rep you drop through is a fall, and falls train nothing.
Why bother
Your bodyweight acts on a lever the length of your torso, with the knee as the only pivot. That produces a torque demand at the knee far beyond what any leg curl stack delivers, and it arrives at the exact moment the hamstring is lengthening. Eccentric overload at long muscle length is the strongest known stimulus for hamstring growth and for cutting strain risk in sprinting.
It is also a brutal honesty test. Most people can lower to about 45 degrees under control, then their hips break and they fold forward. That fold is the tell: it means the hamstrings ran out of knee-flexion strength and the hips took over. A rep with a hinge in it is not this exercise.
Where it fits
Early in a posterior-chain day, before it turns into an endurance grind, or right after your main hinge while you can still brace. Three to five sets of 3-6 controlled negatives is a full session's worth. Expect two to four days of soreness the first few weeks and program it once a week until that settles.
If this one isn't it

Asked and answered
I cannot do a single rep. Where do I start?
Start with the descent only. Lower as slowly as you can, catch yourself on your hands at the floor, and push back up with your arms. Track how many seconds you keep control — going from two seconds to five is real progress even before your first unassisted rep. A band looped overhead and around your chest shortens the road considerably.
Is this the same as a Nordic curl?
Effectively yes. Nordic curl, natural glute ham raise and Russian leg curl all name the same movement: knees fixed, ankles anchored, torso lowered by the hamstrings under eccentric load. The names differ by gym and coaching lineage, not by mechanics.
How is this different from the machine glute ham raise?
The proper GHD machine supports your thighs on a pad and lets you hinge at the hip as well as the knee, so it trains both hamstring functions and gives you an adjustable lever. This version fixes the hip and dumps the entire torso lever onto knee flexion. It is harder, cruder, and needs no dedicated machine.
Will these help my sprinting?
The evidence here is unusually good. Heavy eccentric hamstring work at long muscle length lengthens the muscle's fascicles and substantially reduces hamstring strain rates in sprinting sports. Two sets a week, done with real control, is one of the better returns on time in the whole training library.
