Personally, whenever I get stuck on some weight while squatting for a long time it's usually at least 1 of 2 things happening:
>I can't breathe
>My back gives out
It's never legs for me.
For breathing just do cardio and get a pre-workout with nitric oxide, don't need anything fancy, just bulk l-citruline from chinks or something, if money is a serious issue.
For your back, well, you need to train you back, not your lats, but erectors, rhomboids, lower traps. For me rhomboids and lower traps are usually the problem because I literally feel like my upper back is collapsing.
You might want to stop stims like caffeine, btw, because you might be going through caffeine crash by the time you're getting to heavy squats. So try non-stim preworkouts with nitric oxide instead. Or again buy bulk from chinks, up to you.
