If the knees don't go out, then there's no room for your stomach to go between your legs, which forces you to bow your lower back to continue to lower the weight.
Next time I squat, Thursday, I will film my form from different angles and post it on the forums for criticism. That way maybe I spot or someone spots any problems with my form.
Current: 107kg Squat, 82.5kg Bench, 130kg lDeadlift
Goal: 120kg Squat, 90kg Bench, 150kg Dead
If you let yourself influenced negatively by others then you're following the path to failure.
