A HEAVYWEIGHT fight is a type of combat sport in which two opponents of similar size and weight compete against each other. The term 'HEAVYWEIGHT' is often used to refer to the highest weight class in professional boxing, which is typically between 200 and 250 pounds. SUMO, a traditional Japanese form of wrestling, is also considered a HEAVYWEIGHT fight. In SUMO, two large wrestlers attempt to push each other out of a circular ring or force the other to touch the ground with any part of their body other than the soles of their feet.
