Hip Thrust Guide: Form, Setup, and What the Research Says About Glute Growth

Twenty years ago, the hip thrust did not exist as a gym exercise. It is now the most searched glute movement on the internet, has its own machines in most commercial gyms, and is the anchor of nearly every glute-focused program. The popularity is deserved: it loads the glutes directly, at the joint angle where they work hardest, with weights that no other glute exercise allows. The claims around it have sometimes outrun the evidence. This guide covers both.

What the hip thrust trains

The hip thrust is horizontal hip extension against resistance, with the shoulders elevated so the range is long and the load can be heavy. The gluteus maximus is the prime mover, with the hamstrings, adductors and quads assisting, and the trunk stabilising.

Its distinctive feature is the strength curve. In a squat or deadlift, the glutes are most loaded at the bottom, stretched, and unloaded at the top. In the hip thrust, the load on the glutes is greatest at the top, where they are fully shortened. EMG studies consistently find the hip thrust produces higher peak and mean gluteus maximus activation than the back squat at the same relative load (Contreras et al. 2015; Neto et al. 2020). The two exercises load the same muscle at opposite ends of its length.

Setup

Bench. A flat bench, ideally 35 to 45 cm high, so that when you sit against it the bottom of the shoulder blades meets the edge. Too high and you will slide up and arch; too low and the range is shortened. Anchor the bench against a wall or a rack, because it will move otherwise. Dedicated hip thrust benches and machines solve both problems.

Bar. A thick pad on the bar is not optional; an unpadded bar on the hips is painful enough to limit the set. Roll the bar over your legs until it sits in the crease of the hips, over the pubic bone, not on the stomach. Bumper plates or full-size plates make rolling it into position easier.

Body. Sit on the floor with the upper back against the bench, the bar over the hips, and the feet flat and drawn toward the body. Elbows on the bench, hands lightly on the bar to steady it.

Feet. Hip to shoulder width apart, toes straight ahead or slightly out, placed so that at the top of the movement the shins are vertical. Test it: lock out and look at your shins. If they angle back toward you, the feet are too close; if they angle away, too far.

The movement

1. Tuck the chin toward the chest and keep it there; looking at the ceiling encourages an arched back. Eyes forward, toward the knees.
2. Take a breath and brace the trunk. Ribs down.
3. Drive through the heels and the whole foot, lifting the hips until the torso and the thighs form a straight line from the shoulders to the knees. The knees stay over the ankles.
4. At the top, finish with a posterior pelvic tilt: tuck the tailbone under and squeeze the glutes as hard as you can. The lower back should be flat or slightly rounded, never arched. Hold for one to two seconds.
5. Lower under control, two seconds, until the plates or the hips approach the floor, without fully relaxing.
6. Re-brace and repeat.

The lockout is the exercise. A rep that stops short of a full hip extension with a glute squeeze is a partial rep, whatever the weight on the bar.

The back-arch problem

The single most common fault, and the one that makes people say hip thrusts hurt their back, is finishing the rep by arching the lower back instead of extending the hips. The bar goes up, the ribs flare, and the lumbar spine takes the load while the glutes do less.

The fix is the posterior pelvic tilt: at the top, tuck the pelvis under so the front of the hip bones tilt up toward the ribs. The chin tuck and the "ribs down" cue make this easier. If you cannot lock out without arching, reduce the load. The hip thrust is one of the few lifts where a slight lumbar rounding at the top is the correct position, and an arch is the fault.

Hip thrust vs squat: what the studies show

The EMG advantage of the hip thrust led to the claim that it builds glutes better than squats. Training studies have tested that directly, and the picture is more balanced.

A 12-week study in trained women compared a squat-only program with a hip-thrust-only program. The squat group gained more gluteus maximus thickness, and gained quad size the hip thrust group did not (Barbalho et al. 2020). A 2023 study in young adults compared nine weeks of squats versus hip thrusts and found similar gluteus maximus growth in both, with the squat producing additional growth in the quads and adductors and the hip thrust producing greater strength gains on the hip thrust itself (Plotkin et al. 2023). An earlier study in athletes found hip thrusts improved sprint speed more than front squats, while front squats improved jump height more (Contreras et al. 2017).

The reasonable conclusion: EMG activation does not translate one-for-one into growth; the deep squat loads the glutes at long muscle lengths, which is a powerful growth stimulus in itself; and the hip thrust loads them at short lengths with very heavy weights, which is a different and complementary stimulus. Programs that include both cover the full length-tension curve, and that is what the best-designed glute programs do. See Best Glute Exercises Ranked by Evidence.

Variations

• Glute bridge: from the floor, shorter range, lighter. The starting point and a warm-up.
• Bodyweight and single-leg hip thrusts: for beginners, for the postpartum return, and for hip stability. See Postpartum Return to Lifting.
• Dumbbell or kettlebell hip thrust: easier to set up, limited by how much you can hold on the hips.
• Banded hip thrust: a band anchored under the feet or on a machine increases resistance at the top where the glutes work hardest.
• B-stance hip thrust: one foot slightly forward on its heel, shifting most of the load to the other leg; a useful single-leg progression.
• Machine hip thrust: convenient, stable, and increasingly common.
• Frog pumps, abduction, kickbacks: accessory movements for higher-rep glute work after the main lift.

Common faults and fixes

Programming

The hip thrust tolerates heavy loads and high reps equally well; both have a place.

• Hypertrophy: 3 to 4 sets of 8 to 12, with a pause at the top, once or twice a week. Pair with a squat or leg press in the same program and a Romanian deadlift for the stretched hamstrings and glutes. See Romanian Deadlift Guide.
• Strength: 3 to 5 sets of 3 to 6 at heavy loads, still with a full lockout on every rep.
• Athletic transfer: the hip thrust has evidence for improving sprint speed; 3 sets of 5 to 8 with fast concentric reps.
• Beginners and returns: bodyweight and dumbbell bridges and thrusts, 3 sets of 12 to 15, before loading a bar.
• Progression: add load when every rep reaches a full lockout with a two-second squeeze. Most people progress the hip thrust faster than any other lift; do not let the weight on the bar outrun the quality of the lockout.

The bottom line

Upper back on a bench at about knee height, padded bar in the hip crease, feet placed so the shins are vertical at the top, chin tucked and ribs down. Drive through the heels to a straight line from shoulders to knees, finish with a posterior pelvic tilt and a hard glute squeeze, hold, and lower under control. The hip thrust loads the glutes shortened and heavy; the squat loads them stretched; the research says do both. Lock out every rep, progress only as fast as the lockout allows, and the glutes will follow.
