The heart-racing obstacle course competition series "American Ninja Warrior" returns to NBC this summer with all new episodes. The action-packed series follows competitors as they tackle the world's most difficult obstacle courses in qualifying and finals rounds across the country. Those that successfully complete the courses in each city will move onto the national finals round in Las Vegas and compete for a $1,000,000 prize. In the first Qualifying Round from Venice Beach, California, competitors must tackle six obstacles, including three brand new ones: the Mini Silk Slider, Spin Cycle and Hourglass Drop. "American Ninja Warrior" veterans Kevin Bull and David Campbell return for another shot at completing the course, while former Baltimore Raven & Super Bowl Champion Brendon Ayanbadejo and current NFL player Jon Ryan of the Seattle Seahawks take on the course for the first time. Matt Iseman and Akbar Gbajabiamila return as hosts as Kristine Leahy co-hosts.
