Haley Viloria is a contortionist and performance artist who has traveled the world performing with other circus acts on cruise ships. In this video, she demonstrates some of her moves, many of which somewhat resemble yoga moves until she takes them to a mind-bending (and spine-bending) new level.
The art of contortion has been around for thousands of years in one form or another, with paintings depicting such performers dating back to the days of Ancient Egypt and Greece and historians believe it existed even earlier than that. The most accessible modern equivalent to contortion is yoga, which is itself an ancient Indian practice. Yoga is essentially a series of contortion poses that reportedly induce certain bodily and/or spiritual benefits. Most contortionists like Haley are also avid practitioners of yoga.
