What muscles does a banded kettlebell hip thrust work?

The glutes drive the hips up, the hamstrings assist, the outer hip works against the band throughout, and your abs stop the lift turning into a back arch. The band is what brings the outer hip into it.

Does the resistance band actually do anything?

Yes, and it has been measured. When bridges were tested with and without a band, in 11 healthy physically active adults, the banded version produced more activity in both the large glute muscle and the one on the side of the hip, and it kept a better ratio of glute work to the small muscle at the front of the hip that tends to take over. That test was done lying on the floor rather than off a step, so treat it as the reason the band is there rather than as a number for this exact setup. And only if you push out against it.

My hamstrings cramp every time I bridge. What is causing it?

Because your feet are too far from your body. With the knees bent, the hamstring is slack behind the knee and poorly placed to extend the hip, and the further out your feet are, the more of the work falls to it. Bring your heels in until your shins are near vertical at the top.

Where should your feet be?

Close enough that when your hips are up, your shins point roughly straight up. Because your shoulders are raised, the hips finish higher than they would on the floor, so the feet usually want to be a little further out than you would first guess. Small changes make a large difference to what you feel, so adjust an inch at a time rather than guessing.

How high should the step be?

High enough that its edge meets you just below the shoulder blades when your hips are down, and low enough that both feet sit flat with your knees bent. If the edge lands on your neck or your ribs, it is the wrong height for you and no amount of shuffling fixes it mid-set.

Is a glute bridge as good as a hip thrust?

Closer than its reputation suggests. The one direct comparison found more glute activity in the bridge and more quad activity in the thrust, though it was a small study. Raising the shoulders gives the hips a longer range, which is the real difference; the floor version is not a lesser exercise.

How heavy should the bell on your hips be?

Heavy enough that the last few reps are hard to finish, light enough that you can hold it steady on your hip crease and keep the top position without arching. A bell you have to fight to keep in place is training your hands, not your hips.

Kettlebell hold glute bridge with resistance band

Also called Kettlebell hip thrust, Banded hip thrust, Banded glute bridge, Weighted glute bridge, Hip thrust off a step.

The summary

You rest your upper back on a low step, put a band above your knees and hold a kettlebell across your hips, then push your knees out against the band and drive your hips up. Raising your shoulders off the floor is what makes this a hip thrust rather than a bridge: the hips start lower and finish with your torso level, which is more range than the floor will give you. The glutes extend the hip and do the lifting, the hamstrings assist, and the outer hip works against the band the whole time.

How to do it

Step onePlace a resistance band just above your knees and rest your upper back against a low step or platform, knees bent and feet flat on the floor.
Step twoHold a kettlebell on your hips with both hands.
Step threePush your knees outward against the band and drive your hips upward by squeezing your glutes.
Step fourHold at the top for a moment, then lower your hips back toward the ground with control.

What usually goes wrong

Your hamstrings cramp partway through the set and your glutes barely feel used.

WhyYour feet are too far from your body. The further your feet are from your hips, the straighter that knee stays and the longer the hamstring runs behind it, and the more of the hip extension it ends up supplying instead of the glute. It cramps because it is being asked for something it cannot comfortably give.

FixWalk your heels closer until your shins are close to vertical when your hips are at the top. Then push through your heels rather than your toes. Most people find the cramping stops within a couple of inches of foot exercise.

You feel each rep in your lower back rather than your glutes.

WhyYou are finishing the lift by arching rather than by extending the hip, so the last part of the range comes from the spine.

FixStop where your knees, hips and shoulders form a straight line, with your torso level rather than still climbing. Set your ribs down toward your hips before you lift, and treat the top as a position to hold rather than a height to beat.

Your knees drift toward each other as you lift.

WhyYou are not pushing out against the band, so the band is along for the ride.

FixPress your knees outward before your hips start to rise and keep that pressure on for the whole rep. The band is only worth having if something is working against it.

The step travels away behind you, or your shoulders creep up over its edge as the set goes on.

WhyEach rep pushes back into the step as well as up, and a light platform on a smooth floor will move. Once your shoulders have ridden up over the edge, it is sitting under your neck instead of under your shoulder blades, which is where the whole set gets uncomfortable.

FixPut the step against a wall or a rack upright before you load up, and set the edge so it meets you just below the shoulder blades. Reset between sets rather than shuffling back down mid-set with a bell on your hips.

The kettlebell creeps up onto your stomach and the hold gets uncomfortable.

WhyIt started too high. As the hips rise, a bell above the hip crease slides toward your ribs and stops loading the thing you are trying to load.

FixSet the bell in the crease where your hips fold, hold it there with both hands, and let it press down into that line. A folded towel underneath makes it far more comfortable and changes nothing else.

You are doing the thrust, and the bridge is not the lesser one

The only difference between the two is where your shoulders are. A bridge lies flat on the floor. A thrust, which is what the step here makes this, puts your upper back on a raised edge so the hips can start lower and keep going further before anything stops them. The usual advice follows from that: the bridge is the starter and the thrust is what you move up to.

One study compared them directly, both loaded with a barbell, in 10 men, and it did not come out that way. The thrust produced more activity in the quads. The bridge produced more activity in both the upper and lower parts of the largest glute muscle, at peak and on average, and the authors concluded the bridge was at minimum a fair substitute for the thrust for glute activity.

That is 10 people in one study and two barbell lifts, so read it as a reason to stop repeating the hierarchy rather than as a reason to flip it. What the step reliably buys you is range, and range is worth having. It does not make the floor version a warm-up.

On the thing everyone says about hamstring cramping

Search why your hamstrings cramp in a bridge and almost every answer says the same thing: sitting has made your glutes go to sleep, so your hamstrings step in. It is a tidy story and there is no good evidence for it, and we cannot see how you live anyway.

The explanation that actually holds up is a matter of geometry. Your hamstrings run behind the knee as well as behind the hip, so the straighter that knee is, the longer they run and the more of the hip extension they end up supplying. A muscle asked to do a job that size from a long position is what cramps. That is why moving your feet a couple of inches fixes it and no amount of activation drills does.

It also means the cramp is useful information rather than a fault in you. It tells you your feet are in the wrong place, which is a two-second fix.

What it is for

The kettlebell hold glute bridge with resistance band adds a kettlebell for hip loading and a resistance band to increase hip abductor engagement during the bridge. It targets the glutes with secondary emphasis on the hamstrings and outer hips, making it an effective combined glute exercise.
