I am a big advocate of exercise. I am also an advocate of nudity. But I am not sure I would combine them like this.

The climber is one of a series of super-fit 'Stone Nudes' captured in action on the cliffs and mountains of America.

Without clothes, specialist shoes or other equipment, participants say the experience captures the 'true essence of the climbing spirit.'

It is the latest extreme sport craze to sweep the US, and is now tipped to become a popular pastime in the UK.

While beautiful to behold this seems somewhat less then safe for the climber. I mean what happens if you slip and scrape a sensitive body part on a rock? Ouch!

And I am sure that there are men who also engage in this sport, but really who wants to see that?

You have to admit that the photograph above is beautiful. Unless of course you are a prude. In which case what in the hell are you doing here?
