So I recently started adding squats into my workout, which I recently started back doing full workouts Tuesday. I'm a 3 set guy (I know theres been threads about this lately but I'm stuck in my ways) so I did 3x10, felt a little twinge in my knee on the last few of the last set, didnt think anything of it and didnt notice it the rest of the night. Yesterday, the day after, I went for a run and felt pretty good for the first mile plus and then the lower outside portion of my knee really started hurting (I can only assume the two are related). I thought maybe I could walk it off and tried running on it again after a few minutes and it just got worse and got sore again on the walk to work. Even being somewhat of a hypochondriac, I'm not too worried and think I just tweeked and need to rest it a few days. Seeing as I have never had any training on the excercise, what are some tips for proper normal squat techniques so that I dont hurt my knee, or anything else, anymore?
