Contortion (sometimes contortionism) is an unusual form of physical display which involves the dramatic bending and flexing of the human body.

In general, "contortionists" have unusual natural flexibility, which is then enhanced through acrobatic training, or they put themselves through intense, vigorous and painful training to gain this flexibility.

WOW!
