A B-stance hip thrust is a hip thrust variation where one foot does most of the work while the other foot stays on the ground in a staggered position, acting as a kickstand for balance. It sits in a sweet spot between a standard two-legged hip thrust and a true single-leg hip thrust, letting you load one glute at a time without the balance challenge of lifting entirely on one leg.
How It Differs From a Standard Hip Thrust
In a regular hip thrust, both feet are planted flat on the ground at equal distance from your hips, and both glutes share the load evenly. In the B-stance version, you shift your weight onto one “working” leg and slide the other foot forward so only its heel touches the ground. That supporting leg contributes just enough stability to keep you from tipping, but the glute on your working side handles the bulk of the effort.
This makes it a “pseudo” single-leg exercise. A full single-leg hip thrust removes the second foot entirely, which demands significantly more core stability and hip control. Many people find they wobble too much or can’t use meaningful weight on a true single-leg thrust. The B-stance solves that problem: you get most of the single-leg stimulus with enough support to stay steady and push heavier loads.
Why Use the B-Stance Version
The primary reason is targeting each glute individually. When both legs share the work equally, your stronger side can quietly compensate for the weaker one, and you’d never know. The B-stance forces each side to work on its own terms, which helps reveal and gradually correct side-to-side imbalances.
Research on unilateral (single-limb) training supports this approach. Exercises that load one side at a time activate more stabilizing muscles around the hip, knee, and core compared to bilateral movements. They also train the smaller hip abductor muscles that keep your pelvis level during walking, running, and climbing stairs. Over time, this added stability work can improve force transfer through your entire lower body.
There’s also a practical benefit for people who feel their glutes “turning off” during regular hip thrusts. Focusing on one side at a time often makes it easier to feel the target muscle contracting, which can improve the quality of each rep.
How to Set Up
You need a sturdy bench or platform. The ideal height is roughly 14 inches, though the real benchmark is your knee height when sitting on the floor with your legs extended. If the bench is too tall, your back will arch excessively at the top. Too short, and you lose range of motion. Most standard weight benches work, but adjustable hip thrust platforms are ideal if your gym has one.
Sit on the floor with your upper back against the edge of the bench, roughly at the bottom of your shoulder blades. Roll a barbell over your hips (a pad helps), or hold a dumbbell or plate on your lap if you’re starting lighter. Place both feet flat on the floor with your knees bent so your shins are roughly vertical, feet directly below your knees.
Now set the B-stance: slide one foot forward so that its heel lines up with the toes of your planted foot. Lift the toes of that front foot off the ground so only the heel is in contact. This is your support leg. The foot that stayed in place is your working leg, and you can center it slightly toward the middle of your body for better leverage.
How to Perform the Movement
Drive through the heel of your working leg to lift your hips toward the ceiling. At the top, your shoulders, hips, and knees should form a straight line. Squeeze your glute hard at lockout and hold for a beat before lowering back down with control. You should feel the vast majority of the effort in the glute and hamstring of your working leg.
A few cues that help: keep your chin slightly tucked rather than looking at the ceiling, which prevents your lower back from overextending. Think about pushing the floor away with your working heel rather than lifting your hips. Let your support leg contribute just enough to keep you balanced, but resist the urge to push through it equally.
Complete all your reps on one side before switching the foot position and repeating on the other side. Always start with your weaker side first so it gets your full energy.
Sets, Reps, and Loading
Hip thrusts in general respond well to moderate rep ranges. A well-designed study on hip thrust training for glute growth used 3 to 6 sets of 8 to 12 reps, with loads heavy enough to reach near-failure by the last rep. That framework translates directly to the B-stance version.
If you’re new to the movement, start with 3 sets of 10 to 12 reps per side using just your bodyweight. Once you can complete all reps with a clear glute squeeze at the top and no shifting or wobbling, add a dumbbell on your lap. Progress to a barbell when the dumbbell becomes awkward to balance.
Expect to use roughly 60 to 70 percent of your normal bilateral hip thrust weight. If you typically thrust 200 pounds with both legs, something in the 120 to 140 pound range is a reasonable starting point for the B-stance. Adjust based on feel: if your lower back lights up before your glute does, the weight is too heavy or your setup needs tweaking.
Common Mistakes
The most frequent error is placing the support foot too close to the working foot, which turns it back into a bilateral exercise and defeats the purpose. Your support heel should be noticeably in front of your working foot, with only the heel making contact and toes raised.
Another common issue is hyperextending the lower back at the top. Your ribs should stay stacked over your pelvis at lockout. If your lower back arches aggressively, you’re thrusting too high or letting your core disengage. Think about finishing the rep by squeezing your glutes, not by pushing your belly toward the ceiling.
Finally, watch for hip rotation. Because one leg is doing more work, your pelvis may twist toward the support side. Keep both hip bones pointing straight up at the top of each rep. If you can’t prevent the twist, reduce the weight until your core can stabilize the movement.
Where It Fits in a Program
The B-stance hip thrust works well as either a primary glute exercise or a secondary movement after heavier bilateral work like squats or deadlifts. If glute development is your main goal, place it early in your session when you’re fresh and can push the load. If you’re using it to address an imbalance or improve the mind-muscle connection, it fits nicely as a second or third exercise with slightly lighter weight and a focus on control.
Two sessions per week that include some form of hip thrust is plenty for most people. You can alternate between the bilateral version on one day and the B-stance on another, or use the B-stance exclusively for a training block of 6 to 8 weeks to bring up a lagging side.
