At just 19 years of age, Casey Viator became the youngest man to win the Mr. America title. This impromptu shot from 1971 gives you a pretty good idea why. Under the tutelage of Arthur Jones, on May 16, 1971, Casey Viator won the AAU Junior Mr. America contest. Then, four weeks later, Casey Viator won the AAU Mr. America contest in the most spectacular fashion in the history of such contests. In addition to the overall AAU Mr. America title, Casey took the Most muscular Man in America title and the subdivisions for Best Arms, Best Back, Best Chest and Best Legs.
