The glute-version lower back extension shifts the work from the lower back to the glutes.
On the 45° bench, place the hips just above the pad, feet turned outward, and slightly round the upper back.
Lower the torso by flexing the hips, then rise while squeezing the glutes until body alignment.
Keep the upper back slightly rounded and stop at alignment, without hyperextension.
