‘American Ninja Warrior Junior’ marks the first time some of ‘American Ninja Warrior’s’ biggest fans – KIDS – can become part of the five-time Emmy nominated worldwide phenomenon. ‘American Ninja Warrior Junior’ celebrates real kids taking on the iconic course with dedication and skill. Nearly 200 boy and girl Junior Ninjas from across the United States will face off on the same Head to Head courses in three age brackets: 9 & 10, 11 & 12, and 13 and 14 year olds. Matt Iseman and Akbar Gbajabiamila reprise their roles as hosts and guide kids through the competition along with gold medal-winning Olympic Gymnast Laurie Hernandez as co-host. The finale of ‘American Ninja Warrior Junior’ is set to air April 27 on Universal Kids. The show has been renewed for a second season.
