By Daily Mail Reporter

It is a breathtaking - and death-defying feat - which redefines the term extreme sport.

Battling both gravity and the elements, the climber claws her way up a granite boulder by just her fingertips.

For most, the lack of ropes and safety equipment would be a perilous step too far.

But this woman has gone even further and abandoned her clothes to take part in the new sport of naked rock climbing

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

And as these incredible pictures taken in America show, exercise has never been so attractive.

The 'Stone Nudes' idea is the brainchild of California-based photographer and rock climber Dean Fidelman.
