The middleweight division, from 154 to 160 lbs, has long been one of the most popular in professional boxing. The origins of the weight class can be traced back to the 1840s during the bare-knuckle era of the sport. Gennady ‘Triple G’ Golovkin is regarded as the best middleweight in the world at the moment and that’s backed up by the numerous titles he holds.
Some of the greatest boxers in history have fought as middleweights including Jake LaMotta, Sugar Ray Robinson, Carmen Basilio, Dick Tiger, Emile Griffith, Carlos Monzon, Marvin Hagler, Roberto Duran, Sugar Ray Leonard, Tommy Hearns, Felix Trinidad, Roy Jones Jr., Oscar De La Hoya and Bernard Hopkins.
