Matt Iseman From American Ninja Warrior Season 15

"American Ninja Warrior" has returned with some of the most elite athletes in the country competing on the world's most difficult obstacle courses. Hosts Matt Iseman, Akbar Gbajabiamila and Zuri Hall are back to call the early-round action in San Antonio and Los Angeles with the National Finals in Las Vegas. The new season will mark the return of the lowered age requirement, which opens the door to a new era of competitors as young as 15 years old. Each season, the obstacle courses continue to evolve and become even more challenging for competitors of all ages, while the sport itself simultaneously grows rapidly across the country with kids embracing it in record numbers. A top prize of $1 million will go to the winner who can conquer all four stages at the National Finals in Las Vegas. To get there, competitors will need to make it through the qualifying rounds and Semifinals.
