Ladies in red —
Introducing the remarkable contortionists of Cirque du Soleil's legendary Las Vegas Stage show, called "O."

Head over heels —
The show has been running at the Bellagio Hotel and Casino for the last 15 years, featuring clowns, trapeze artists and contortionists.

Bending over backwards —
The Cirque du Soleil contortionists train for up to three hours-a-day in preparation for their spectacular show.

Behind the scenes —
Of the show's 20 contortionists, almost all are women, and almost all hail from one country: Mongolia.

World stage —
"Mongolian contortion is globally competitive -- today many performers are working for Cirque du Soleil and other international circus companies," said Nomintuya Baasankhuu, Arts Program Director at the Arts Council of Mongolia.

Child's play —
The road to circus stardom starts early in Mongolia, with children as young as five training up to three hours a day with organizations such as the Mongolian State Circus (pictured).

Strength, flexibility, balance —
"In order to learn how to balance your body on your hands and on other people, you need to gain upper body strength. My homework used to be 300 push ups a day," said former contortionist Baasankhuu.

Magic Mongolians —
While Mongolian contortion has some similarities with ancient folk dances and yoga poses, it really took off as a professional art form with the launch of the State Circus in the 1940s.

No pain, no gain —
"Training from an early age is a huge factor in their success. Nobody is naturally a contortionist in adulthood. This level of flexibility requires a regimented and focused long term training program, lasting years," said Tim Allardyce of the British Osteopathic Association.

Suspend belief —
"It is so fluid and almost magical the way they can move their bodies. I think it is breathtaking," said Ria Martens, Cirque du Soleil artistic director.
