Need a list of reasons. Our weight room manager whom never works legs only squats in the smith machine and goes down 8 inches with 225 lbs. for his squat day. I saw our security guard who is older doing the same thing and I informed him that it is much better to barbbell squat and the manager just called bull**** even though I told him some facts about it. Need some help so I can bring him a list of reasons why from actual powerlifters.
