Butt Lift (Bridge)
Also works: Hamstrings
Lying on your back with knees bent, you drive through your heels and lift your hips until your body forms a straight line from knee to shoulder. It is the entry point to every loaded hip thrust variation, and its real job is teaching you to extend the hip with glutes rather than by arching your lower back.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Lie on your back with knees bent and heels pulled in until your fingertips can just brush them.
- Set your feet roughly shoulder-width, toes pointing straight ahead or turned out no more than 15 degrees.
- Press your arms flat to the floor at your sides, palms down — they are for balance, not for pushing.
- Flatten your lower back into the floor and tuck your ribs down before the first rep.
- Take the weight into your heels. You should be able to lift your toes and still hold the position.
Every rep
Breathing & tempo — Exhale as the hips rise, inhale as they lower. Two seconds up, a one-second hold with a hard squeeze, two seconds down, and no rest on the floor between reps.
Sets, reps & load
Where to start, and what to change when it stops being hard.
Bodyweight to start. When 20 reps with a one-second squeeze is easy, progress in this order: longer holds, then single-leg, then a dumbbell or plate resting across the hips, then a barbell hip thrust off a bench. Do not chase 50-rep bodyweight sets — that is endurance work, not glute development.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Keep your ribs pulled down and stop the rep the moment your hips are level with knees and shoulders. If you feel it in your lower back rather than your glutes, you went too far.
Walk your heels in until you can just touch them with your fingertips. Feet close to the glutes bias the glutes; feet out in front bias the hamstrings and invite cramping.
Lift your toes off the floor for a set of ten. If you cannot hold the bridge that way, your weight is too far forward — shift back into the heels and rebuild from there.
One second of hard glute squeeze at the top of every rep, counted out. A bodyweight bridge without a pause has almost no stimulus left in it once you are past the first fortnight.
Why bother
The glutes are strongest at full hip extension, which is exactly the position squats and deadlifts spend the least time in. Lying supine puts peak resistance at the top of the range instead of the bottom, so the hardest part of the rep is the part a squat barely trains. That is the whole argument for bridging.
The catch is that the lower back can fake it. Hyperextending the lumbar spine raises the hips a few extra centimetres and looks like a longer range, but the glutes never finish the job. The honest end point is a straight line from knee to hip to shoulder with your ribs still down — not the highest your hips will physically go.
Where it fits
Two places: as a two-minute glute activation before squatting or deadlifting, at 15-20 easy reps, or as accessory volume at the end of a lower-body day at 3 sets of 20 with a hard squeeze. Once bodyweight sets of 20 stop being challenging, stop adding reps and move to a single-leg version or a loaded hip thrust.
If this one isn't it

Asked and answered
Why do I feel this in my hamstrings instead of my glutes?
Almost always foot placement. Heels too far from your backside puts the hamstrings in a longer, stronger position and they take over. Walk your feet in until your fingertips brush your heels, then squeeze the glutes before the hips move. Cramping hamstrings are the classic sign you have this wrong.
How is this different from a hip thrust?
A hip thrust puts your upper back on a bench, which roughly doubles the range of motion and lets you load a barbell across the hips. The bridge is the floor version: shorter range, bodyweight only, and no equipment. Treat the bridge as the pattern and the thrust as the loaded expression of it.
Do glute bridges help with lower back pain?
Sometimes, and not for the reason people think. They do not strengthen the back. What they can do is teach you to extend the hip without arching the lumbar spine, which is the pattern that spares the back when you stand up from a chair or pick something off the floor. If bridging itself hurts your back, you are arching at the top rather than finishing with the glutes — cut the range and keep the ribs down. Pain that does not change with technique needs looking at, not more reps.
Will bodyweight bridges actually grow my glutes?
For a beginner, for a few months, yes. After that, no. The load stops being meaningful and adding reps just builds endurance. Once 20 controlled reps with a squeeze are easy, go single-leg or put weight across your hips — progression is the point, and this movement runs out of it quickly.
