Bodybuilding is more than a sport; it is an art and culture. It differentiates itself from performance sports as the athletes are judged on appearance rather than athletic ability on competition day. Bodybuilders pose onstage where they are judged on muscularity, definition, and symmetry. During a season, bodybuilders go through three different phases: muscle-gaining phase (off-season), dieting for competition (contest preparation) and the competition itself. Most of the literature surrounds the dieting phase .
