Dorian Yates definitely ushered in the era of the ugly bodybuilder. The man was gifted several times with a Sandow when he looked absolutely atrocious. I don’t remember what year it was, but he came in with a torn biceps on his left arm. He had tiny knot on that arm, and his regular bicep on the other side. In a rear double biceps pose, his biceps were invisible. In his later years of winning, his gut usually preceded him onto the stage. Todays bodybuilders are definitely monsters, and they can look stunning from the front view, but turn them sideways, and there is that ugly gut protruding beyond their pecs. The midsection of a bodybuilder should be concave, not convex, it detracts from the v-taper.
In the 1970s, bodybuilding had major publicity thanks to the appearance of Arnold Schwarzenegger , Franco Columbu , Lou Ferrigno , and others in the 1977 docudrama Pumping Iron . By this time, the IFBB dominated the competitive bodybuilding landscape and the Amateur Athletic Union (AAU) took a back seat. The National Physique Committee (NPC) was formed in 1981 by Jim Manion ,  who had just stepped down as chairman of the AAU Physique Committee. The NPC has gone on to become the most successful bodybuilding organization in America, and is the amateur division of the IFBB. The late 1980s and early 1990s saw the decline of AAU-sponsored bodybuilding contests. In 1999, the AAU voted to discontinue its bodybuilding events.
