lower your training max. The best way to increase your squat is to squat. Instead of doing front squats for assistance, just do 3-5 sets @ FSL weight. Your training max should be a weight you can lift for 5 solid reps. I try to set my training max to where I can hit 10 reps on my 1+ week. For instance, my training max in the squat is 425 and on my 1+ week , I squatted 405x7. Not exactly 10, but I'm hitting more than 5 reps on my 95% set. If you're not, your TM is too high.
