Contestants on American Ninja Warrior are known to be tough, but Artis Thompson III (nickname: AT3), who has a prosthetic leg, may be one of the toughest people who ever competed on the show.
If you've ever watched the show, you'll know that it's quite rare for anyone to complete any of these challenges.
Artis lost his left leg in a motorcycle accident. As it turns out, he lost a brother in a similar accident three years prior to his own.
Artis' run was definitely inspirational to us and it also earned him the "Run of the Night."
