Quadruples are the culmination of generations of figure skating and snowboarding progress. Axels or Corks, these maneuvers defy what was thought possible for Olympic athletes. On this episode on The Podium, we explore the dizzying abilities required of modern competitors and the ramifications on artistry and injury. Vincent Zhou was the skater first to land a quad lutz at the games and shares his journey  with Marcus Kleveland, the youngest snowboarder to land a quadruple cork to understand the biggest move in Beijing.

Listen to Season 3 of NBC Sports' The Podium hosted by Lauren Shehadi.
