Since becoming the first-ever “American Ninja Warrior” winner and establishing himself as a climber of rare talent, Isaac Caldiero has continued to compete on the show. After his 2015 win, he took a brief break from the competition, becoming a spokesman and working with the show’s sponsor, POM Wonderful pomegranate Juice. Specifically, the company ran a sweepstakes, and the winner was provided a training program that involved meeting Isaac and working out with him.

Since then, he has returned to the “Ninja Warrior” franchise several times, beginning in 2017, when he was announced as a competitor on “Ninja Warrior Germany.” He returned to Season 10 of the American format in 2018 when he was 36. In an interview with Entertainment Weekly, Caldiero explained that he had been watching the competition in the intervening years and was looking forward to rejoining the fray. He got to Stage 4 of the finals.
