OMG THIS. Watch The First Woman EVER To Finish The American Ninja Warrior Finals Course.

Seriously, everyone needs to watch this video. I'm speechless! 24-year-old Kacy Catanzaro made history as the first woman ever to complete the finalist's course on American Ninja Warrior.

Kacy is only 5 feet tall, and this course should be IMPOSSIBLE for someone this tiny but SHE DID IT.
