If you've ever watched the obstacle course show "American Ninja Warrior," you know that its defining trait is that basically no one can complete it. Lovable goofballs, Crossfit goons, personal trainers, Navy SEALs ... the course chews people up and spits them out.

But then along comes a five-foot-tall, 100-pound gymnast. And she completely kicks the course's ass. Like with feats of strength.





And by RUNNING STRAIGHT UP A DANG WALL.





And by being the first woman to ever complete the salmon ladder.





OR MAYBE THIS.





Kacy has become the first woman to ever qualify for the season finals. Hopefully she'll run roughshod over everyone there. We bow to you, Kacy Catanzaro. We are not worthy.
