Recenty i've gotten back into squats. When i do squats with my legs fairly close together like i would with a body wieght squat my knee's pop like crazy on every rep. So i tried putting my legs a little further apart than shoulder width and that problem complete went away. The the problem is when i have them this far apart which isn't that far apart i only feel it in my hips and butt. The next day i was extremely sore in those areas, but not my quads at all. I'm thinking this may because my butt and hips are really weak compaired to my legs and need to catch up. I'm hoping this is what it is. What do you guys think?
