i love 8 x 3 personally. Yes, but blaming injuries on improper form is like blaming car crashes on two cars hitting each other at speed. When people try too much weight, too any reps, whatever else is usually the actual cause of the injury. People squat/run/lift/whatever for years and still get injured. They know how to do it, but the body doesn't always respond the way they'd like it to. Why 8x3? I mean, I could see that working, but keep the reps the same just for mental practice if nothing else. Try Madcow's 5x5...I personally think it makes more sense and it works better for people who are accustomed to lifting. In my experience this doesn't matter much. I squatted with olympic shoes, without olympic shoes, high bar, low bar, good mornings only, etc. I tended to stick with high bar and good mornings mostly because it helped me run better on the track, but the high bar/low bar distinction is one that can't be applied to every lifter. If you're tipping forward during a squat, it's because the resistance is too high so your body tries to pull more with your glutes and hamstrings. There's nothing inherently wrong with this (it's what a good morning/low bar squat tends to focus on more), but if you can't keep your upper body stable it's because you don't have enough strength in your hips to lift the weight when the higher bar position requires additional torque. As a little diagram, look at the top lever's resistance compared to the fulcrum (in the case of squats, the hip is the fulcrum). Then look at the lower lever's. Which requires more force to overcome the resistance? This is the high bar/low bar distinction as it pertains to the hip extensors (i.e. glutes and hamstrings); a high bar squat is more like the top lever, while a low bar is more like the bottom lever. N.B. the arrows are indicating the direction the lever will move. In other words, the resistance is the box and its force is gravity. That's probably understood, so don't let the arrows make you think otherwise.
