You would think that a guy spending all of his time shaping and strengthening his muscles could bet out any guy in an arm wrestling contest. Nope. This video if proof that it isn't always about having big muscles.

It is amazing to watch a man with smaller, leaner muscles beat out a guy with double the size arms in an arm wrestling match.

Watch in amazement as the pro arm wrestler smile as he holds of a pro body builder in this game of strength.

Want some more awesome? Check these guys out. Can't get better arm wrestling than two guys with mullets.
