Well where do i start.
I high bar squat almost 90% of the time and have in meets.
I utilize a very low box squat as deadlift assistance (low bar style sitting back) but with the bar still up on my traps. I usually do 2 second pause box squat with my ass just barely on the box.
They do absolutely nothing for my squat since i squat high bar and im only doing 3 sets of 5 at a worked up max usually to 385x5 some days ill push to 405 but only do 2 reps or 1.
I dont try to go to crazy on these sets.
If youre a raw squatter i dont know why people dont use a box lower than what they already go with with normal depth i think utilizing a box squat below your normal squat depth would help build explosiveness out of the hole.
But i do believe people do them for different reasons and all those people that are opposed to box squats are missing out on a really good movement if doing for the right reasons.
Im not gonna say im an expert squatter or even close but i think im decent only one pler at my gym can put up more weight andnhe uses low bar and has been training for 7 years he squats 610 without wraps.
I nearly forgot about using them for deadlift assistance. I know STB who used to post here mentioned that. The stuff I’ve read that Louie Simmons wrote always seems to suggest narrow stance low box squats for building the quads and lower back for deadlift carry over. I had to give up on that one because it made me feel like I was about to crap my SI joint onto the box.
