Ben Kooper is a knife salesman from California who has competed on three seasons of American Ninja Warrior.
American Ninja Warrior 13[]
He first competed on ANW 13 in the second round of qualifying. His run was cut, but it was revealed that he failed the Tipping Point, and didn't go fast enough to make the top 30.
American Ninja Warrior 14[]
He then competed on ANW 14 in the last qualifier. His run was once again cut, but he fell even earlier, going out on the second obstacle, the Shattered Panes.
American Ninja Warrior 16[]
He returned on ANW 16 in the fourth qualifier. This time, he put up a good run to the fifth obstacle, Jawbreakers, before falling. He placed 12th overall, leading him to compete in the runoff races against Guang Cui, who placed 13th.
During the runoffs, they were even throughout most of the race. Ultimately, Kooper failed on Sideways, while Guang completed the course, earning Guang a spot in the semifinals and eliminating Kooper.
