They're musclefatties. They aren't fit, exactly, but the common fatty is just an amorphous blob of lard. The musclefatty is basically like you took someone really fit and wrapped them in 100 pounds of lard. Their stamina suffers and their aesthetic sucks but they can lift a ton and hit like freight trains.
Because its not attractive. That being said, basically every fitizen wants to be bear mode; which is one step down from sumo. A shit tonne of muscle, with not much fat. Where sumos are basically 2 shittonnes of muscle and as much fat as they packed on getting there.
