Ever seen two dudes brawling and the nerdy guy whom you wouldn't think could fight a yawn ends up beating the crap out of the other guy?

Except, some do. In fact, these guys do. And whether you think they have any business being jacked or not, the following geeks have flouted stereotype to forge physiques that defy expectations. That thing about Germans is still true, though.
