Many do not believe that gender plays a role when it comes to who is more flexible than the other. Scientifically women are more flexible than men, and this is because of how their connective tissues are made up. Though the record shows that women are more flexible, an American Contortionist named Daniel Browning Smith was known as the rubber boy because of his ability to flex more than any woman. He was seven times Guinness World Record as the most flexible person in history.
