American Ninja Warrior is hard enough with two arms and two legs, but imagine doing it with only one leg. Zach Gowen, a fellow Michigander, placed twelfth in the Indianapolis Qualifier. Cancer took Zach's leg, but that didn't stop him from signing a three year deal with WWE, and competing on American Ninja Warrior. Many veteran warriors were there to cheer Zach on. His biggest achievement was probably completing the log roll. It's nearly impossible to do without both your legs wrapped around the log, but Zach made it look easy. Congrats to Zach!
