Bodyweight Single-Leg Hip Thrust
What Is the Bodyweight Single-Leg Hip Thrust?
Bodyweight Single-Leg Hip Thrust is a compound exercise that primarily targets the glutes and also engages the hamstrings, adductors and core. It is a beginner-level movement performed with the upper back resting against a flat bench, one foot planted on the floor and the other leg held in the air, so a single leg drives the whole hip up and back down again.
Standing the movement on one leg is the point of it. Hip extension strength splits unevenly between sides more easily than most people expect, and a two-legged thrust lets the stronger hip quietly cover for the weaker one. On one leg there is nothing to hide behind, and the gap shows up in reps, in range and in how level the pelvis stays. The single-leg position also adds a side-to-side control demand that the two-legged version barely asks for, because the gluteus medius and minimus on the working side have to stop the pelvis dropping or twisting toward the free leg.
In a session it works as accessory glute work after the main lift, as part of a warm-up before squatting, hinging or sprinting, or as a step in a bridging progression for someone building back up to loaded hip extension. It has no competition or testing role, and it does not need one: a bench and a bit of floor is the entire equipment list, which is why it survives travel, home gyms and clinic floors.
Foot position steers where the work lands. With the heel set so the shin finishes close to vertical, the glute does most of the extending; sliding the foot farther from the bench opens the hip angle and hands more of the job to the hamstrings, which is the usual reason a set ends in a hamstring cramp rather than a glute burn. Body weight only takes this so far, though. A study of 14 female footballers that estimated gluteal muscle forces across eight hip-focused exercises, the single-leg hip thrust among them, found that a 12-repetition-maximum load raised peak gluteal muscle forces by 28 to 150 N compared with the same exercises done with body weight alone. Once you can finish your target sets without the last few reps feeling hard, the next step is load rather than more reps: Dumbbell Single-Leg Hip Thrust, Machine Single-Leg Hip Thrust or Barbell Single-Leg Hip Thrust.
This is not the same exercise as Bodyweight Feet-Elevated Single-Leg Hip Thrust, where the working foot sits on a box instead of the floor. Raising the foot deepens the hip flexion at the bottom and lengthens the range, which makes it the harder of the two and a later step, not an alternative setup for this one. Start here with the foot flat on the floor, and if holding the pelvis level on one leg is still too much, build up with Glute Bridge and Bodyweight Hip Thrust first.

Instructions
- Sit on the floor with your upper back against the long edge of a flat bench, so the edge of the pad crosses your back just below the shoulder blades.
- Plant one foot flat on the floor roughly in line with that hip, with the heel set far enough forward that the shin will finish close to vertical at the top of the rep. Start with your weaker leg.
- Lift the other leg off the floor with the hip bent and the knee relaxed, and hold it there for the whole set. It never touches down and never pushes off.
- Rest your arms along the top of the bench for balance, but keep your weight off them.
- Brace your abs and keep your head in line with your torso so the ribs stay down and the lower back stays neutral.
- Drive through the heel and midfoot of the planted foot and push the hips up until your torso and thigh form a straight line.
- Stop there, with hips level and both hip bones at the same height, and squeeze the glute for a moment.
- Lower under control until the hips are just above the floor, keeping the free leg in the air and your back in contact with the bench.
- Finish all the reps on that side, then switch legs and match that number rather than beating it.
Common Mistakes
Finishing with the lower back
Arching the lumbar spine to push the hips higher once the glute has run out, instead of stopping when the torso and thigh form a straight line.
Letting the pelvis tip toward the free leg
Allowing one hip bone to sit lower than the other at the top, which takes the side-to-side control work away from the gluteus medius on the working side.
Planting the foot too far from the bench
Setting the working heel out so far that the hip stays open at lockout, which hands the extension to the hamstrings and is the usual cause of a mid-set cramp.
Pushing through the arms
Pressing down into the bench with the elbows or hands to help the hips up, which hides how much the single leg is actually doing.
Rising onto the toes
Letting the heel come off the floor so the drive shifts to the forefoot and the calf, which costs the glute leverage at the top.
Cutting the bottom of the range
Stopping the lowering phase halfway and bouncing back up, which shortens the range that made the bench setup worth using in the first place.
Injuries
Bodyweight Single-Leg Hip Thrust is a low risk exercise when performed with proper technique. There is no external load, the torso is supported against the bench for the whole rep, and a set that fails simply ends with the hips back on the floor. The risk that remains comes from how the rep is finished rather than from how heavy it is.
The lower back is the usual complaint. When the working glute runs out before the hips are level, it is easy to arch the lumbar spine to buy a few extra degrees of height, which turns a glute exercise into a low-back exercise. Hamstring cramping is the second one, and it almost always traces back to a working foot planted too far from the bench, which leaves the hip open at the top and the hamstrings doing the extending. The bench edge itself can bruise the back over a long set, and a bench that sits much above knee height can pinch at the front of the hip at the bottom of the range.
Most of that is fixed in the setup. Brace the abs before the first rep so the ribs stay down, and treat a straight line from shoulder to knee as the end of the rep rather than a checkpoint on the way to a higher one. If the hamstrings start to cramp, walk the heel an inch or two closer to the bench and slow the tempo to around two seconds up and two seconds down. Use a padded bench, keep the shin of the planted leg close to vertical at the top if the knee is sensitive, and drop the bench to roughly knee height if the front of the hip pinches.
If holding the pelvis level on one leg is not there yet, build it with Glute Bridge and Bodyweight Hip Thrust before coming back to this. When it becomes easy, progress with load through Dumbbell Single-Leg Hip Thrust or with range through Bodyweight Feet-Elevated Single-Leg Hip Thrust. Stop the set if you feel sharp pain in the low back, the front of the hip or the knee, or any pain that does not settle when you change the foot position, and see a clinician before loading the pattern if you are working around a current hamstring, hip or back problem.

Frequently Asked Questions
- Q: Where exactly should the bench sit on my back?
The edge of the pad should cross your back just below the shoulder blades, about an inch below their bottom tips. Higher than that and the bench presses into your neck; lower and your shoulder blades end up flat on the pad, which shortens how far the hips can travel.
- Q: What am I supposed to do with the free leg?
Hold it in the air with the hip bent and the knee relaxed, and leave it there for the whole set. It should not swing for momentum or tap the floor between reps. Holding the leg out straight instead is a balance challenge rather than a harder job for the working glute.
- Q: Why do my hamstrings cramp instead of my glutes working?
That almost always means the working foot is planted too far from the bench, so the hip is still open at the top and the hamstrings finish the rep. Walk the heel an inch or two closer until the shin is close to vertical at lockout, and slow the rep down to about two seconds each way.
- Q: How is this different from the feet-elevated version?
Here the working foot is flat on the floor. In Bodyweight Feet-Elevated Single-Leg Hip Thrust the foot sits on a box, which drops the hips into deeper flexion at the bottom and gives a longer range, so it is the harder of the two and comes later.
- Q: How many reps and sets should I do per leg?
Two to three sets of 8 to 15 reps per leg is a reasonable starting point for most people. Do the weaker side first and match its number on the stronger side, so the gap closes instead of widening.
- Q: When should I start adding weight?
Once you can finish three sets of 15 per leg with a pause at the top and the last reps still feel easy, body weight has stopped being a training stimulus. At that point move to Dumbbell Single-Leg Hip Thrust rather than pushing the rep count higher.
