Bodybuilding is the process of developing muscle fibres through the combination of weight training, increased caloric intake, and rest. Someone who engages in this activity is referred to as a bodybuilder. As a sport, called competitive bodybuilding, bodybuilders display their physiques to a panel of judges, who assign points based on their aesthetic appearance. Bodybuilding has contributed to the success of many public figures worldwide. Examples include Arnold Schwarzenegger, Lou Ferrigno, Steve Reeves and Serge Nubret.
In the 1970s women began to take part in bodybuilding competitions. Extremely popular at first, the interest in the competitive side of female bodybuilding has waned sharply in recent years even though more women than ever are training with weights, due to the increasingly masculine appearance of female bodybuilders. In recent years, the related areas of fitness and figure competition have gained in popularity, providing an alternative for women who choose not to develop the level of muscularity necessary for bodybuilding. The first Ms. Olympia contest in 1980, won by Rachel McLish, would resemble closely what is thought of today as a fitness and figure competition.
