Heels in the straps, hips to the sky.
Squeeze your glutes at the top, don't let your lower back do the lifting.
With legs straight and heels pressing into the cradles, lifting your hips turns into a long-lever hamstring exercise, the hamstrings working hard to hold hip extension with almost no knee bend to help them. The glutes assist at the top, squeezing you into that shoulders-to-heels line and keeping the lower back out of the job. It is worth programming as the entry point to suspended hamstring work, teaching the bridge position you will need before pull-ins, runners and curls make any sense.
Leg position. The bridge keeps legs straight so the hamstrings carry the load at long length, the glute bridge bends the knees and shifts the emphasis onto the glutes.
You are lifting with arch instead of hip drive. Brace your core, squeeze your glutes to push the hips up, and stop at a straight line rather than cranking higher.
It is the right starting point for suspended hamstring training, yes. Own slow controlled bridges first, then progress to the hamstring runner or pull-in where the knees start moving.
