Contortionists are known for their extreme flexibility, but they can only twist and turn one way - that is, forwards or backwards.
Russian-born former gymnast, Zlata, is both a back and forward-bender, and one of the world's most flexible person.
The 29-year-old extreme contortionist, whose real name is Julia Guenthel, has been contorting since she was just four years old.
The bendy blonde, who now resides in Germany, trains daily to keep her muscles in shape, the Daily Mail reported.
One of her favourite acts is bending herself backwards at a perfect 90-degree angle. According to the Daily Mail, Zlata can even fit herself into a 50cm square box.
Zlata has a rare condition which means her tendons are extremely pliable, allowing her to adopt painful-looking positions for lengthy periods of time.
Doctors have been examining her body to understand her "superhuman elasticity". Zlata's flexibility lies in her ligaments. Her ligaments are like a baby's - elastic and stretchy.
Zlata, who did gymnastics back in school, told the Daily Mail that she gave up on the sport after she was bullied by other girls in school. She later joined an after-school circus instead where she learnt the art of contortionism.
While doing contortionist poses feels almost second-nature to her, it can get a bit uncomfortable during long photo shoots.
Zalta now spends most of her day working out and training for shows around the world.
