Season Four: Apolo Anton Ohno and Pro Partner Julianne Hough
Short-track speed skater Apolo Anton Ohno took part in the 2010 Winter Olympics, winning one silver and two bronze medals, but more importantly earning the distinction of being the most decorated U.S. athlete of all time in the winter games. He developed a nutrition supplement business called 8 Zone, and since the games, he has created the Apolo Anton Ohno Foundation, which promotes active, healthy lifestyles by encouraging people to make positive choices.
