The phrase "champion bodybuilder" refers to a person who is excellent at building and sculpting their muscles through weightlifting and exercise. They have won competitions or achieved great success in their field.
I have not seen statistical evidence, but anecdotal lore suggests that champion bodybuilders do, indeed, die young, often of heart diseases (indicating muscle damage). (perfecthealthdiet.com)
