Quintuple champion Quintuple champion In different sports an athlete who wins five crowns, titles, medals, belts, or other distinctions is called a Quintuple Champion. In boxing, a quintuple champion is a boxer who has won world titles in at least five different weight classes. The first man in boxing to earn this distinction was Thomas Hearns on November 4, 1988. Hearns won first the Welterweight (147 lbs) title, later annexed the Super Welterweight (154 lbs) belt. Rather than win the next closest division in weight, the Middleweight (160 lbs), he moved up to three divisions to earn the Light Heavyweight (175 lbs)
Weight class (boxing) Weight class (boxing) A weight class is a measurement weight range for boxers. The lower limit of a weight class is equal to the upper weight limit of the class below it. The top class, with no upper limit, is called heavyweight in professional boxing and super heavyweight in amateur boxing. A boxing match is usually scheduled for a fixed weight class, and each boxer's weight must not exceed the upper limit. Although professional boxers may fight above their weight class, an amateur boxer's weight must not fall below the lower limit. A nonstandard weight limit is called a catchweight.
