Derek Hough just crashed a zumba class to spread awareness about mental health

Derek Hough shocks dancers when he makes a surprise visit at their zumba class in NYC. One class member says, "Is this really happening?!" Derek is the only six-time champion in history of the ABC show “Dancing with the Stars." The world’s largest dance fitness brand, Zumba, is teaming up with Derek Hough, Emmy Award-winning dancer and NBC’s World of Dance judge, for a new global movement called 'Zumba Breaks'. The movement is launching leading up to Mental Health Awareness Month. It encourages people around the world to take just a few minutes out of their day to get up and move to improve their mental health.
