Somehow we never tire of seeing this guy in his undies. Earlier this year, we wrote about hot and hairy Ben Cohen and his many good works. Through his StandUp Foundation, the former rugby star has led an international campaign to fight homophobia and bullying, especially among gay youth. The sexy Brit even partnered with Bluebuck for an exclusive line of StandUp underwear and was its lead model. Now, Ben has gone before the cameras once again for a calendar for the new year. Of course, the proceeds will benefit his worthy cause. And what's more fun than watching this big beefy guy in action!? Check out the video above to see the athletic activist posing in his briefs and doing all sorts of manly things, like lifting weights, boxing and tossing a ball around. We can't wait for 2013!
