obviously..its all relative...but, sarcasm is partly correct. lots of guys are bigger than sammy, he is not a huge bodybuilder, he is short and has a small frame, but the muscle quality he has is amazing and on a bodybuilding stage he is among the elite in the world. (top 10 in the world)
but as for pure size, most gyms have taller dudes with bigger structures (and not always just fat..but obviously carrying more fat than sammy..) who would dwarf sammy, but on a bodybuilding stage they would look pathetic next to him.
lots of bouncers would dwarf many of the IFBB pros..because many of em are under 6'0 feet.
if you put a dude who is 6'3 285lbs with wide shoulders and clothes on..he will almost dwarf a bodybuilder who is 5'6 235lbs (who is carrying less fat and more muscle pound for pound)
