LOS ANGELES - There's nothing more manly than two large men in loincloths engaging in the age-old, full-contact practice of competitive sumo; if there is we have yet to see it.
Actually, sumo is an intense sport. take a look at what happened at the 2013 U.S. Sumo Open in Los Angeles when 340-pound Ulambayaryn Byambajav (aka "Byamba") took on 400-pound Kelly Gneiting.
Byamba is the 3-time world champ and Gneitling is a 5-time U.S. Sumo champion, so they both know their craft.
Byamba gets low on Gneitling, grabs his mawashi (wrestling belt) and goes beast mode with a belly-to-belly body slam.
The match only lasted about five seconds, and by no surprise Byamba went on to win the whole event.
Gneitling is no pushover, though. He holds the Guiness World Record as the heaviest human ever to run a marathon, a goal he's reached three times.
