Glute Bridge: How to Do It, Muscles Worked and Mistakes to Avoid
How to do a glute bridge with good form, which muscles it works, the mistakes that shift it into your lower back, and how to progress, with an honest look at glute bridges vs hip thrusts.
A glute bridge is a floor exercise where you lie on your back with your knees bent and squeeze your glutes to lift your hips toward the ceiling. It trains the glutes and hamstrings with little stress on your knees or spine, needs no equipment, and suits beginners, people easing back from back or knee pain, and lifters warming up for squats and deadlifts.
| Primary muscles | Gluteus maximus |
| Secondary muscles | Hamstrings, gluteus medius, lower back muscles (erector spinae), deep abdominals |
| Equipment | None (a mat helps); a loop band, dumbbell or barbell to progress |
| Difficulty | Beginner |
| Movement pattern | Hip extension (hinge) |
| Good for | Glute strength, warm-ups, back- and knee-friendly leg work, training at home |
| Starting sets and reps | 2 to 3 sets of 10 to 15 slow reps, 2 to 3 days a week |
How to do a glute bridge
- Lie on your back on a mat, knees bent, feet flat and hip-width apart.
- Set your heels. Slide them toward you until your fingertips can almost touch them. Rest your arms by your sides, palms down.
- Brace. Pull your ribs down slightly and tighten your stomach as if about to take a light punch.
- Lift. Breathe in, then breathe out as you press through your heels and squeeze your glutes to raise your hips.
- Stop at a straight line from shoulders to hips to knees. Going higher only arches your lower back.
- Squeeze and hold for about one second at the top.
- Lower slowly over about two seconds, breathing in, until your hips lightly touch the floor. Reset and repeat.
Form cues
- Feel it in your glutes, not your lower back or hamstrings.
- Keep your heels planted; your toes can even lift slightly.
- Gently push the floor apart with your feet to keep your knees in line with your toes.
- Look at the ceiling, head on the floor, chin slightly tucked.
- Tempo: one second up, one second squeeze, two seconds down.
Muscles worked
The glute bridge is a hip extension: your hips go from bent to straight. The gluteus maximus, the large muscle of your buttocks, does most of the work. Your hamstrings assist, the gluteus medius on the side of your hip keeps your pelvis and knees level, and your back extensors and deep abdominals hold your trunk steady.
How hard do they work? Less than many people assume. In an electromyography (EMG) study of 30 healthy adults, the two-leg and single-leg bridges both stayed below 45% of a maximal contraction in the muscles measured, a level the authors linked to endurance and stability rather than strength (1). Another lab measured higher glute activity in the single-leg bridge, roughly 47 to 58% (2). Either way, the bodyweight bridge is a starting point, not the finish line.
Foot position changes which muscles take over. In 25 active men, bending the knees more, with the heels closer to the hips, shifted work toward the gluteus maximus, while straighter legs handed it to the hamstrings and lower back (3). In a single-leg bridge study of 28 young adults, bending the working knee to 135 degrees instead of 90 cut hamstring activity from about 75% to 23% of maximum while glute activity held steady (2). Hence the heels-close setup in step 2.
One caution: EMG shows how active a muscle is, not how much it will grow. In a 9-week trial, the hip thrust produced higher glute EMG than the back squat, yet both built similar glute muscle on MRI scans (4).
Common mistakes
- Arching your lower back. Lifting too high, or without bracing, moves the work into your lower back. Fix: ribs down, tuck your pelvis slightly before you lift, and stop at a straight line.
- Pushing through your toes. When your heels come up, your thighs take over. Fix: press through your heels and keep them down.
- Letting your knees cave in. Fix: push the floor apart with your feet. A light loop band above your knees gives you something to push against.
- Feet too far away. The usual cause of hamstring cramps, because straighter legs hand the work to the hamstrings (3). Fix: walk your heels closer.
- Rushing. Bouncing off the floor swaps muscle for momentum. Fix: pause at the top and take two seconds to lower.
Variations: easier and harder
| Level | Variation | Why and when |
|---|---|---|
| Easier | Seated glute squeeze | No floor needed. In an 8-week trial, daily seated squeezes improved hip extension strength as much as daily bridges (5). |
| Easier | Short-range bridge | Lift your hips only a few inches, for when a full bridge irritates your lower back. |
| Standard | Bodyweight glute bridge | The version above. Master 3 clean sets of 15 before progressing. |
| Harder | Paused or banded bridge | A three-second squeeze at the top, or a loop band above your knees for the outer hip. |
| Harder | Single-leg bridge | One leg does the work. Bend the working knee past 90 degrees to keep it in your glutes (2). |
| Advanced | Dumbbell or barbell glute bridge | A padded weight across your hips. The simplest way to keep adding resistance. |
| Advanced | Hip thrust | Shoulders on a bench for a longer range and heavier loads. See below. |
Knee, back or wrist limits? The bridge spares your wrists, and your knees stay bent but barely move, which is why it appears in our knee pain exercise routine. With a touchy back, start short-range and build up, as in our lower back pain exercise routine. For banded versions, see our guide to the best resistance bands for strength and mobility.
Sets, reps and how often
Start with 2 to 3 sets of 10 to 15 slow reps, two or three days a week, then match your training to your goal, using the American College of Sports Medicine (ACSM) position stand on progression (6):
| Goal | What to do | Rest between sets |
|---|---|---|
| Beginners | Bodyweight bridges, 2 to 3 sets of 10 to 15 | About 1 minute |
| Muscular endurance | Light to moderate load, more than 15 reps | Under 90 seconds |
| Muscle growth | Several sets with a load you can lift 6 to 12 times, using single-leg or loaded versions | 1 to 2 minutes |
| Strength | Over time, heavier loaded bridges or hip thrusts in the 1-to-6-rep range | 3 to 5 minutes |
Effort matters more than the exact numbers. A meta-analysis of 21 studies found light loads built as much muscle as heavy ones when sets went to failure, though heavy loads built more maximal strength (7). Fifteen bridges you could repeat 30 times do little; fifteen that leave two or three reps in the tank do far more. Then progress: the ACSM suggests adding 2 to 10% load once you beat your target by one or two reps (6). With bodyweight, move down the variations table instead.
Two or three sessions a week is plenty. A meta-analysis of 25 studies found that with weekly volume equal, training frequency made no meaningful difference to growth (8). Light bridges as a daily warm-up are fine too.
Glute bridge vs hip thrust: which is better?
They are the same movement from different heights. In a hip thrust your shoulders rest on a bench, so your hips travel farther and a heavy barbell is easier to set up. The bridge needs nothing but floor.
The direct evidence is thin. The two head-to-head studies we found point in different directions. One compared the barbell versions in 10 men: the glute bridge produced more gluteus maximus activity, while the hip thrust worked the front of the thigh more (9); one author was affiliated with an exercise equipment company. A 2026 study of 20 healthy men found the opposite for bodyweight versions: the hip thrust, with the upper back on a bench, produced more gluteus maximus activity than the floor bridge (12). Both measured muscle activity only, so neither tells you which builds more muscle. Our hip thrust guide covers the loaded version in detail.
We found no trial comparing how much muscle each builds. The closest evidence is the trial above, where the hip thrust out-activated the squat but did not out-grow it (4). Two of its authors sell exercise-related products and services and partly funded its participant and MRI costs.
Our take: start with the bridge, and move to the hip thrust when single-leg bridges feel easy and you want heavier loads, or pick whichever you feel more in your glutes.
What is the best glute exercise?
There isn’t one. A systematic review of 16 EMG studies placed many loaded exercises above 60% of maximal glute activation, with step-ups at the top, followed by variations of deadlifts, hip thrusts, lunges and squats (10). Since activation is not growth, pair a bridge or hip thrust, which works your glutes when they are shortened, with moves that load them on a stretch, such as the Romanian deadlift and the goblet squat.
What will 100 glute bridges a day do?
Less for glute size than you might hope, but something for strength. The closest test asked university students to do 15 minutes of bodyweight bridges daily, at about five seconds per rep, for 8 weeks (5). They averaged about 8 minutes a day, roughly 90 bridges, and gained about 11% in hip extension strength, with no significant change in hip girth.
So 100 daily bridges make a good warm-up habit and somewhat stronger hips. For bigger or much stronger glutes, you need harder sets, not more easy ones: single-leg or loaded bridges taken close to failure (7).
How long should you hold a glute bridge?
For normal reps, about one second at the top while you squeeze hard; a three-second pause makes each rep harder. For a hold, there is no research-backed ideal time. Hold while you can keep a straight line from shoulders to knees without your back arching or hamstrings cramping, building from 20 or 30 seconds toward a minute.
Is it safe? Who should be careful
The glute bridge is one of the gentlest strength exercises there is, but a few rules apply:
- Pain: muscle effort and mild next-day soreness are normal. Stop if you feel sharp pain, pain shooting down a leg, numbness or tingling.
- Lower back pain: use a shorter range, keep your ribs down and don’t chase height. If bridges reliably make your back worse, get it checked.
- Hamstring cramps: bring your heels closer and bend your knees more (2, 3).
- Pregnancy: the UK’s National Health Service advises avoiding activities that involve lying flat on your back for more than a few minutes in later pregnancy (11). Keep sets short, roll onto your side between them, and ask your midwife or doctor about alternatives.
- Recent surgery or injury to the hip, spine or knee: follow your surgeon’s or physical therapist’s plan first.
See a physical therapist or doctor if pain lasts more than a couple of weeks, stops you from doing daily tasks, or comes with leg weakness. This page is general information, not medical advice; please read our medical disclaimer.

Frequently asked questions
What does a glute bridge work?
Mainly the gluteus maximus, the large muscle of your buttocks. Your hamstrings help lift your hips, the gluteus medius on the side of your hip keeps your pelvis and knees steady, and your lower back and deep abdominal muscles hold your trunk still. Keeping your heels close to your hips puts more of the work on your glutes and less on your hamstrings.
What will 100 glute bridges a day do?
Make your hips somewhat stronger, but probably not much bigger. In an 8-week study, students who averaged about 8 minutes of bodyweight bridges a day, roughly 90 reps, gained about 11% in hip extension strength with no significant change in hip girth. To build more muscle, make each set harder with single-leg or weighted bridges taken close to failure.
How long should you hold a glute bridge?
About one second at the top of each rep while you squeeze your glutes hard; a three-second pause makes each rep harder. For an isometric hold there is no research-backed ideal time. Hold for as long as your body stays in a straight line from shoulders to knees without your back arching or your hamstrings cramping, building from 20 or 30 seconds toward a minute.
Are glute bridges as good as hip thrusts?
For many people, yes. Both train the same hip extension movement. The hip thrust puts your shoulders on a bench, which gives a longer range of motion and makes heavy barbell loading easier. Small EMG studies disagree on which works the glutes harder: one found more glute activity in the barbell bridge, a 2026 study found more in the bodyweight hip thrust, and no trial has compared how much muscle each one builds. Start with the bridge and move to the hip thrust when you want heavier loads.
What is the best exercise for your glutes?
There is no single best one. EMG research ranks step-ups, deadlifts, hip thrusts, lunges and squats among the exercises that work the glutes hardest, and higher activation does not guarantee more growth. A balanced plan combines a bridge or hip thrust with a hinge such as the Romanian deadlift and a squat or lunge.
