B-Stance Hip Thrust
How to Do a B-Stance Hip Thrust
Set up for a normal hip thrust with the upper back supported on a stable bench.
Place the working foot flat in your usual hip-thrust position.
Move the other foot slightly forward or staggered so it can provide light support without becoming the main driver.
Keep the pelvis square and use bodyweight first while learning the stance.
Brace the trunk and drive through the working foot to extend the hips.
Finish with the working glute contracted and the ribs controlled rather than arching the lower back.
Lower the hips under control while keeping the support foot light.
Complete the planned reps, then switch stances and match the same range and tempo.
Form Check & Technique
DO THIS (Technique Tips)
- Master the bilateral hip thrust first.
- Keep the support foot light.
- Keep the working foot flat.
- Keep the pelvis level.
- Finish with glute-driven lockout.
- Use moderate loading.
- Progress to single-leg thrusts when B-stance reps become easy.
AVOID THIS (Common Mistakes)
- Pushing Too Hard With the Support Foot — Fix: keep that foot light and reduce load if needed.
- Pelvis Rotating — Fix: keep both hip bones level and square.
- Hyperextending the Lower Back — Fix: finish with the glutes and controlled ribs.
- Support Foot Placed Too Far Away — Fix: bring it closer until balance feels stable.
- Using Too Much External Load — Fix: use bodyweight or lighter resistance to preserve the unilateral bias.
- Rushing the Reps — Fix: lower and lift under control.
- Changing Stance Between Sides — Fix: reproduce the same foot positions before comparing strength.
About B-Stance Hip Thrust
The B-stance hip thrust is a staggered-stance hip thrust in which one leg does most of the work while the other foot acts as a light kickstand for balance. It sits between a bilateral hip thrust and a true single-leg hip thrust: more unilateral than the two-leg version, but more stable than lifting the support foot completely off the floor. Keep the pelvis level and use the rear foot only lightly.
B-Stance Hip Thrust Muscles Worked
Onnit describes the gluteus maximus as the main target and the gluteus medius and minimus as important pelvic stabilizers.
- Strong Curves also lists the glutes as primary, with hamstrings and core assisting.
Sets & Reps Guidance
Technique / Learning
Technique: 2–3 sets of 10–12 bodyweight reps per side.
Strength Focus
Loaded accessory: 3–4 sets of 6–10 reps per side with moderate resistance.
Muscle Growth (Hypertrophy)
Muscle growth: 3–4 sets of 8–15 reps per side with strict working-leg emphasis.
General training baseline. Need.fit automatically adjusts exact sets, reps, and working weight based on your individual fitness level, recovery, and progress over time.

B-Stance Hip Thrust vs Regular Hip Thrust
A bilateral hip thrust uses both feet and supports heavier loading. The B-stance shifts more work to one side while keeping enough support to remain more stable than a full single-leg thrust.
B-Stance Hip Thrust vs Single-Leg Hip Thrust
Onnit calls the B-stance a middle ground between two-leg and single-leg hip thrusts. The support foot stays on the floor, so balance is easier, but the working side still receives more emphasis.
Where Should the Support Foot Go?
Strong Curves describes the working foot as flat with the other foot used lightly for support. Exact spacing is individual; use a stagger that lets you keep the pelvis level and clearly feel the front leg doing most of the work.
Should You Use an 80/20 Weight Split?
Treat percentages like 80/20 as a cue, not a measurement.
- The practical goal is simply to make the working leg dominant and the staggered foot light.
- If the support leg is pushing hard, reduce load or adjust stance.
How Heavy Should You Load B-Stance Thrusts?
Onnit recommends mastering bodyweight first and cautions that very heavy loading can make you rely more on the support leg. Use enough resistance to challenge the working glute without losing the unilateral bias.
Using B-Stance Hip Thrusts for Side-to-Side Differences
Because each side is trained separately, the exercise makes strength and control differences easier to notice. Start with the weaker side and match the same reps on the stronger side if symmetry is a goal.
How to Program B-Stance Hip Thrusts
Use them as a unilateral glute accessory after heavier bilateral thrusts or as a bridge toward true single-leg hip thrusts. Moderate reps are usually easier to control than very heavy low-rep work.
