Francesco Maria Columbu was an Italian-American bodybuilder, powerlifter, actor, author, producer, and a licensed chiropractor.

Bodybuilding is the practice of progressive resistance exercise to build, control, and develop one's muscles via hypertrophy. An individual who engages in this activity is referred to as a bodybuilder. It is primarily undertaken for aesthetic purposes over functional ones, distinguishing it from similar activities such as powerlifting and calisthenics.
