I implemented glute bridges as a part of my routine for a few months at the beginning of this year. I was mainly aiming for better glute activation as a part of a "battle" against my anterior pelvic tilt. Did a couple of light sets for warmup before squats, and then treated it as assistance (in the 10-12 rep range). They helped and I liked them.
Sorry to ressurect this really old thread, but found it when searching for glute stuff after seeing the Bret Contreras thread. Wondering what else you did to "battle" anterior pelvic tilt (as I understand it this is back rounding in the squat right?) and what you think worked best?
