Knee clicking, popping, and creaking should not be a problem unless you are experienceing acute pain with any of them. Four things improved my squatting and knee health. The first two have been mentioned: Knee sleeves and flexibility. The other two are proper footwear and proper stance. For footwear, do not squat in cushioned shoes. Use something hardsoled, I use chuck taylors. I discovered that when wearing running shoes one of my Knees was colapsing, due to the “crushing” of the padding. I will also occasionaly squat barefoot. Oly shoes are another option. As far as stance goes, some people are more comfortable ultra wide while others really close. I prefer a slightly wider than shoulder width with my toes pointing out slightly, no more than 45 degrees. I do use other stances from time to time, but when I’m going for a max lift, it’s always the described stance.[/quote]
I’d always been quad-dominant, and ‘learned’ the squat from magazines. My problem was caused by squatting narrow with my knees caving in being a problem when maxing out. Now, i’m gonna rest up til pain subsides, reset weight low-low and start to be a slightly-wider-than-shoulders squatter.
