There’s a reason that sumo wrestlers, weight lifters, wrestlers, and gladiators aren’t(/weren’t in the last case) slender. Fat can be very advantageous in a fight and the presence of fat does not mean poor exercise. A lot of the bodybuilders with ridiculous muscles and “athletic bodies” actually aren’t all that strong comparatively, because they specifically work to make their muscles for show, not efficiency.

Coelosquid makes a good point about it here.
