mentzer had cool old school thick build yeah blocky a bit but strong looking and enough conditioning for that era,,,make no mistake about it those pics are cool barefooted,tank top,heavy iron,all lifting on top of each other ,,they were sauced to the gills as much or even more open than today but they had better grade drugs,stopped when needed,somewhat accepted getting smaller or softer ,,today with contracts and media,supp contracts they can't mention steroid one bit.
