Strength comes in a lot of different shapes and sizes, as this video of two guys arm wrestling proves. 

While the guy on the left is clearly pretty proud of his guns and his strength, given that he's wearing a tank top and a backwards cap (the hallmark of a total bro), he hadn't taken into account that his opponent might be pretty good at this arm wrestling criac. So good that he can snap a selfie before he effortlessly claims a victory.
