Soaking up knowledge I know for me, with squats and anytype of side to side lunge I have to remember to focus on using my glutes, and hinging from the hip first. I tend to want to overload my quad and that causes my knee to cave in. My mantra is "stick your butt out first" and it seems to help. I can't step to the side at all when I am in any sort of squat, admire those who can.
