Suspend your feet, thrust those hips, own the instability.
Move steadily to manage the strap wobble and finish with a hard glute squeeze.
Shoulders on a bench, feet floating in the cradles, this hip thrust makes the glutes drive full hip extension while simultaneously pinning down straps that want to drift with every degree of movement. The hamstrings assist, working overtime as stabilisers because the floor is no longer holding your feet still. It earns its spot as a bodyweight thrust that feels far heavier than it reads, the instability recruiting more from the same movement without a single plate involved.
Your feet are in hanging cradles, so any lazy or uneven drive makes them swing. You have to push straight down through your heels and extend evenly, which is exactly what makes them effective.
Yes, the setup rests your upper back on a bench so the hips travel through a full range. Without it you are doing a glute bridge from the floor, which is a shorter movement.
Slow down. Steady tempo, heels driving straight down, and a hard glute squeeze at the top keep the cradles quiet. Speed is what sets them swinging.
