Bodybuilding is a competitive sport based on the development of muscles through the combination of weight training, increased caloric intake and rest. Bodybuilders display their physiques to a panel of judges, who assign points. The first bodybuildingschool was established by Theodor Siebert (ger) in 1901. The International Federation of BodyBuilders was founded in 1946. In the 1990's the Fitness competitions were added in which next to the aesthetics and athletic physique gymnastic routines are performed. A medium event for women was added called Body Fitness, where the emphasis is on aesthetics and athletic physique, without a fitness performance.
