B-Stance Hip Thrust

Move · Resistance Training · Movement, Typed Supps

The rear foot is a kickstand, not a second working leg.

Stage by stage

Set-up (Rear foot light and behind): The trailing foot sits behind the working heel with only enough contact to stabilise.
During the set (Peak torque at lockout): Unlike a squat, the hip extension moment is highest at full extension where the glutes are shortest.
Late in the set (Working hip does the work): Pressing through the rear foot is the common fault, converting the lift back into a bilateral thrust.
Months later (Load with symmetry): Heavier loading than a true single-leg thrust while keeping a unilateral bias evens out side differences.

Muscles trained

Primary: glutes
Secondary: abs, hamstrings, hip abductors

Intensity

5 METs (Resistance (weight) training, squats, slow or explosive effort).

Time to effect

Weeks: Balance and per-side effort become obvious quickly — most people find they can push meaningfully harder on the working leg than they expected once the second leg stops helping.
Months: Because it allows heavier loading than a true single-leg hip thrust while still emphasizing one side, this tends to build both glute strength and side-to-side symmetry efficiently.

Common myth

"The back foot means this is basically a two-legged hip thrust." In reality: The rear foot contributes only a small stabilizing assist — most coaches estimate the working leg still does the large majority of the lifting.
