I think through all the 'posterior' rhetoric we've been fed over the years, people forget that the primary function of the quads is to extend the knee.
Stance helps people get depth, if you can't hit depth when squatting you don't know how to squat. The primary function of the quad has nothing to do with my comment on isolating the quad muscles.
The majority of novice lifter's have poor to no hamstring development and the same can be said about a majority of westside barbell lifters who use quads and lower back so much they need special exercises and machines such as box squats and reverse hyper machines to try and fix their imbalances.
