This.  Holy shit. I used to think they were trying to get into shape.  They're not.  They're loving out some delusional fantasy.  Fun story,  I had one try and critique my technique while squatting.  He told me I was going down too far (I was going parallel).  So I watched this fat fuck try to demonstrate proper technique. I was squatting 285 (I weigh 150) and he went down maybe 45 degrees, with wobbly legs,  and then came back up.  I was dumbfounded. I just laughed and said "ok, thanks man" and totally disregarded him.
