"I can still rule the yard if I have to," Randy Couture told Muscle & Fitness during his cover shoot for our September issue. The Expendables 2 star didn't have any delusions of still being 25, but there's no doubt that he can still kick some serious ass when he needs to. The Army veteran, professional wrestler, MMA legend and now action megastar is, at 49 years old, still in better shape than most guys in their 20s. 

He talked to us about how his experiences have translated from the cage to the big screen, life after the UFC and what every guy needs to do to stay in fighting shape after 40 in this exclusive behind-the-scenes video.
