Frank Zane is a three-time Mr. Olympia, Mr. Universe, as well as a former Mr. America and Mr. World. His physique is widely regarded as the gold standard for aesthetic bodybuilding. In April 2015, the editors of Muscle & Fitness dubbed his physique the greatest of all time. An early adopter of supplements—especially amino acids—at a time when supplementation was not common, he earned the nickname "The Chemist." He is the author of several books, including "High Def Body." His monthly column appears in M&F.
