If you could stick someone's arms or chest on you body, whose would it be? For me it would be Flex Wheeler's arms circa 1993, or Phil Heath's arms, and JOJ's chest circa 2006-2007.
Flex's because they were a perfect circle when Flexed, plus his bis and tris were perfectly developed-and tris stuck out on the side. Heath's well, enough has been talked about Heath's. JOJ's chest is probably the most complete in history.
Honorable mention goes to Aaron Baker's arms...the man was very under-rated, but if you take a look at him on the BFTO 1997, where hie is doing skull crushers with Robby Robinson, you see why...his trs and bis are off the hook.
