Is it possible for a fat to be physically capable? I was reading about a sumo wrestler named Byamba who is fat (round, saggy) but only has 11% bodyfat. It made me wonder about all these fats who claim to be able to run marathons, ironman competitions, etc. Does such a thing as a physically capable fat exist? How are they getting these ridiculous ideas that a fat person can actually DO anything? Or is each one just trying to be the first of their kind and failing?
