Shaun T
Carl Daikeler and Jon Congdon launched the Beachbody fitness company in 1998. They were looking for new fitness workout home videos. They approached Shaun T who submitted a demo which would later be called "Insanity", released in 2009. It was termed "the hardest workout put on DVD". It was sold through TV ads. Because of the difficulty of the workout and its popularity, Shaun T has been a guest on The Oprah Winfrey Show, The Tyra Banks Show, Doctors and the Dr. Oz Show.
