It has been quite some time since posting on this forum, but I am in need of some help. I've recently took better stock in my nutrition and recovery and have seen incredible gains in both size and strength. Primarily my squat has really shot up. Prior to me noticing some slack in my form I was comfortably doing 225lbs. for 10 reps, but as I started tightening everything up I noticed I was having a slight round in the back and my butt tucking slightly under my hips. I always squat ass to the floor. I have done a few things to try and correct this but I lose about half of my squatting strength and still end up have the same outcome. Any tips?
