Bodybuilding is a form of body modification involving intensive muscle hypertrophy; an individual who engages in this activity is referred to as a bodybuilder. In competitive bodybuilding, bodybuilders display their physiques to a panel of judges, who assign points based on their appearance. The muscles are revealed through a process known as the "cutting phase" - a combination of fat loss, oils, and tanning (or tanning lotions) which combined with lighting make the definition of the muscle group more distinct.
Well-known bodybuilders include Charles Atlas, Steve Reeves, Reg Park, Arnold Schwarzenegger, and Lou Ferrigno. Currently, three-time winner Jay Cutler holds the title of Mr. Olympia as the world's top bodybuilder.
