Tsatsral Erdenebileg from Mongolia holds incredible Gusiness World Record for the Marinelli Bend for 4 mins 17 secs.
Marinelli bend is a form of contortion posture in which the performer (most often female) supports their whole body weight only by biting onto a mouth grip attached to a short post in a backbend position with their buttocks sitting on their own head. It is considered to be one of the most difficult and dangerous contortion positions, and is usually the climax during a contortion performance.
