A floor version of the hip thrust with a shorter range of motion, good for learning to extend the hips with the glutes.

What each muscle does in the glute bridge

Muscle	Role	Action

Primary muscles are the prime movers; secondary muscles assist or stabilise. The balance shifts with grip, stance, range of motion and technique.
