I've recently added in some squatting sets to my workout, and people keep telling me different things about the foot stance. When I get down to parallel height, it feels natural to keep a 35-45 degree outward slant with my feet. But some people are saying that can hurt my knees that way and I should be keeping them as straight as I possibly can. And others are saying whatever feels right when you are down to parallel level is what I should use to avoid injury. So, which is the correct form?...
