Also known as: ruppel_backbend
A very difficult Contortion position in which the performer stands and bends their back until their head is peeking through their thighs. An even harder variation of this position includes bending the back even further until also the shoulders find themselves in front of the performer's thighs.
The position was first successfully performed by German contortionist Alina Ruppel on July 27th 2009, giving it the name the Ruppelbend.
