Welterweight

Welterweight is a weight class division in combat sports. Originally the term "welterweight" was used only in boxing, but other combat sports like kickboxing, taekwondo and mixed martial arts also began to use it for their own weight division system. In most sports that use it, welterweight is heavier than lightweight but lighter than middleweight.
