8 Franco Columbo

Although Columbu stands only 5’5″, his pecs were not only stupendously thick, but, unlike others of his stature, they were also large from top to bottom and side to side, and they could have looked at home on 6’5″ Lou Ferrigno. Their most unique quality was the unparalleled cleft that segregated the upper region from the rest, as if the upper pecs were separate muscles (they’re not).

The two-time Mr. O (1976, ’81) attributes most of his size to barbell presses (flat and incline) and dips.
