Chuck Liddell and Heidi Northcott's TMI workout video: It's all about the shoes

chuck-liddell-350.jpgUFC legend Chuck Liddell has already shown a willingness to embrace unusual training methods -- he did, after all, appear on "Dancing with the Stars" last fall.

Now he and girlfriend Heidi Northcott are engaging in another rather unorthodox gym routine: Video of the duo working out naked is circulating online. Or almost naked, anyway -- they're wearing shoes, which is the point. The video is part of a viral campaign for Reebok.

Do we even have to tell you it's not safe for work? Liddell and Northcott in all their pixellated glory after the jump.
