Please everyone, stop taking powerlifting advice from physical therapists and movement "experts". If you need to be able to squat correctly you need to put a bar on your back and squat - period. Al this other crap - goblet squats, split squats, zercher squats, etc can be used to aid the squat but when you begin to substitute this stuff for the squat you get into trouble. Squatting is a skill which needs to be practiced. When I see Andy Bolton, Benedikt, Koklaev, Konstantinovs, doing goblet squats, then maybe I may think about using them. You have limited training time and recovery ability, why waste it with stuff that doesn't carry over. That's my rant. KISS principle always.
