Well not every powerlifter is 350lbs and fat...many are lean and more dense than bodybuilders...some actually compete in bodybuilding competitions in their off seasons...check out scott mendelson and mike ruggiero etc...these are some shapely and big dudes...out muscle and strength any bodybuilder including ronnie, who was i might add a powerlifter before bodybuilding and still incorporates some of the same principles in his training!
I think it's cool but at the same time these dudes aren't doing much for their health Lotsa body fat, abnormal amounts of pressure on joints and bones... so on and so on.
Andy Fiedler is lean and is the heaviest man to do tripple bodyweight benching. Glen Chabot also got very lean at one point, the only fat guys are SHWs because that is what they do. The bigger they get, the stronger they get, and they are looking for the big numbers outside of normal weight classes.
