My whole upper body tilts forward when going up from the bottom. Not upright enough. You could say my chest drops but I probably also lose a bit of upper back tightness.
Deloading seems like the logical solution although I absolutely hate it. Want to move more weight, not less
Maybe paused squats?
Same thing happens to me, usually on the last rep or two. Technique and supporting muscles are so limiting on the squat, leg strength i should be moving a lot more weight, but it's hard to get everything to come together. I'd say a lot of it is to do with glutes not activating which is a huge problem for me, they are so loose in a squat. Moved 100kg for 2 x 4 today improved on last weeks 100 x 3RM.
Been squatting as my lower power exercise for about a month now, might swap it out for deadlifts soon, although i'm never sure if deads actually provide much hypertrophy.
