Apparently, 'The Ultimate Fighter' legend Chuck Liddell works out in the nude with his girlfriend. We're with Jimmy Kimmel on this.

"I don't work out a whole lot," he said on 'Jimmy Kimmel Live' (12:05AM ET on ABC), "but I was under the impression that people wore clothes when they did."

I guess if you can spend $20,000 for gym equipment, you don't have to worry about spending any money for pants. Either that, or you're too broke to buy pants. And Liddell really needs them with those chicken legs.

Props to the lurker who shot the video. Would not want to be in that guy's shoes when Liddell caught up with him.

Watch the video after the jump.
