UFC heavyweight Roy Nelson has had his ups and downs since winning TUF and earning a spot in the Octagon, but a few things are undeniable about him: he’s tough, he’s skilled, and damn is he fat. But if you have the first two qualities, why not embrace that last one wholeheartedly? Therefore, in preparation of his September UFC Fight Night 52 bout against Mark Hunt, Nelson is in Japan doing the one athletic endeavor that requires its athletes to be as portly as possible. That’s right, Nelson is doing some sumo wrestling.

As per the UFC Instagram account, here’s Nelson getting his sumo on. Note that he is not wearing the traditional diaper these dudes wear – whichever PR person insisted upon that, they have my eternal gratitude.
