To me it sounds like you loaded up the bar more than you could comfortably handle, and had a form breakdown. If we're descending further into anecdote territory, I had a leg injury when I was in my mid teens which cased me to limp slightly. My friends used to make jokes that if I was ever fleeing a crime scene, they'd know who it was. Squatting didn't really help, until I dropped the weight down to noob levels and focused on getting the best form possible. I can now walk completely normally, and my limp is entirely gone. Squats can definitely be used to rehab injuries. >>41149582
You keep focusing on the big numbers, but that wasn't the only point in my original argument. Regardless, you're barking up the wrong tree. My 5rm is currently less than 2pl8; I stopped and deloaded quite significantly and I'm not focusing primarily on form. Feels amazing.
As for the growth response, true, but squats and deadlifts both train a lot of muscles at the same time. You'd have to do multiple isolations to match it. Compoud lifts are a pretty handy tool to have. >Squatting is supposed to help you the lifter. Not be the reason that you lift.
Something that helps you get somewhere, not the destination in and of itself.
That's definitely true, and at no point did I say it was the goal in itself, barring powerlifters. But it's still a very handy tool, and I think that it's definitely not "shit", like the OP post claimed.
