This video is lengthy but I found it very useful in bringing to light how obviously not everyone is built the same and not everyone should set up for their squat the same. Either depending on mobility or body type your squat might be totally different from the person squatting right next to you. The goal is to find your safest, most stable, strongest position that allows you to move as efficiently as possible. There is no one size fits all to this thing.
