Illia Yefimchyk, known as the world’s “most monstrous bodybuilder,” has died at the age of 36 after suffering a heart attack. Yefimchyk, who earned the nickname “The Mutant” due to his impressive physique, was admitted to a hospital on September 6 after a heart attack and fell into a coma, the New York Post reported.

He passed away on September 11. Yefimchyk’s wife, Anna, performed chest compressions while waiting for an ambulance. “I spent every day with him, hoping for recovery. His heart started beating again for two days, but doctors informed me that his brain had stopped functioning,” she told local media.

Standing 6 feet tall and weighing 340 pounds, Yefimchyk maintained his massive physique through an extreme diet, consuming up to 16,500 calories a day, according to The Post. His meals reportedly included over five pounds of steak and more than 100 pieces of sushi across seven meals. He was known for his impressive lifting capabilities, claiming a 600-pound bench press, 700-pound deadlift, and 700-pound squat.
