Weight classes are divisions of competition used to match competitors against others of their own size. Weight classes are used in a variety of sports including rowing, weight lifting, and especially combat sports[1] such as boxing, kickboxing, mixed martial arts, wrestling, and Brazilian jiu-jitsu. Alternatives to formal weight classes include catch weight and openweight.
The existence of weight divisions gives rise to the practice of weight cutting. To be the largest individual in a weight division is perceived as advantageous; therefore many athletes lose weight through dieting and dehydration prior to weigh-ins to qualify for a lower weight class.[2]
Below are selected maximum weight limits for the major classes in different sports.
