Frank Zane, a three-time Mr. Olympia (1977-79) is considered to be among the strongest bodybuilders in history. Zane, with his near-perfect symmetry and clean lines, had the most muscular physique during his bodybuilding days. The legendary bodybuilder often said that during the peak of his career, he primarily focused on compound movements to challenge his strength and consumed a lot of carbs and protein before training.He says:I relied a lot on pre-workout food. Before the training, I always had protein and carbs. After the training, I relaxed and sometimes ate a few hours later. It all depended on how demanding my training was. When I got hungry, I just ate. Usually, my first meal after training was a protein drink – some sort of protein-carbohydrate mix."
