Flex Wheeler

Legendary bodybuilder Flex Wheeler is renowned for having a perfectly symmetrical body. It was discovered that he has an extremely rare genetic disorder. A study analyzing 62 incredible weightlifters, nine were diagnosed with having a myostatin deficiency mutation. Myostatin is a protein that prevents the body from building muscle. Flex was one of them. In fact, out of the nine men, he had the rarest mutation-the 'exon 2' gene. This mutation gave him significantly more muscle fibers than the other test subjects in this study and ridiculously more than a normal human.
