Season 16 of "American Ninja Warrior" returns with the most elite athletes in the country competing on the world's most difficult obstacle courses. Hosts Matt Iseman and Akbar Gbajabiamila, along with co-host Zuri Hall, are back to call the action as the ninjas make their way through the qualifying and semifinal rounds in Los Angeles before moving to the national finals in Las Vegas. Continuing with the major changes from last season, the semis will challenge the ninjas to race side-by-side and head-to-head across a high-stakes course with a spot in the national finals on the line. All four stages in Vegas return, including the Stage 4 rope climb for $1 Million. Episodes air Monday nights at 8/7c. They will be paused for two weeks during the Olympics (7/29 and 8/5) and during this time Matt will be doing live coverage of the Games on Peacock.
