Zane is a three-time Mr. Olympia (1977 to 1979). His reign represented a shift in emphasis from mass to aesthetics. Zane's physique featured the second-thinnest waistline of all the Mr. Olympias (after Sergio Oliva), with his wide shoulders making for a distinctive V-taper. He stood at 5 feet 9 inches (1.75 m) and had a competition weight of less than 190 pounds when he won all three of his Mr. Olympias. He was given the nickname "The Chemist" due to his Bachelor of Science degree and, as he puts it: "Back in the day I took a lot of supplements and tons of amino acids. Still do. But back then it was pretty unusual. That's how I got the nickname The Chemist."
