Don't worry, you don't have to have seen American Ninja Warrior before to enjoy this clip. The insane difficulty will be instantly evident. The premise of the show is that there's an obstacle course that is impossible to complete, even by people who would easily be the best athletes you ever meet. No woman has ever completed the qualifying course, let alone the finals course. On this week's episode, gymnast Kacy Catanzaro was the first woman to attempt the finals course, and she completely destroyed it. Watch below and be inspired — inspired not to, you know, exercise, but in a more general, non-physical way.
