So, I incorporated some of the advice from you guys, and some of my own methodology, into improving my squat. Happy to say that it is working; I hit a 275 lb. front squat yesterday on my third set, and after 225X5, 275X5, and 315X2 high-bar squats I took 345 really deep and came up with it like it was my first rep of the day.
Static holds, weighted abs, and mid-back rowing/pulling movements are helping a lot to increase my thoracic strength and keep from folding over. I'm down 6 pounds bodyweight too, so I'm getting stronger as I cut weight.
