I've played sports quite literally ALL my life. I've done P90x, Insanity, 9Round kickboxing, yoga, etc, but not in a million years would I be able to complete this course. This girl KILLS it, AND she makes it look easy!! SO awesome!

Her name is Kacy Catanzaro. She's only five feet tall, 100 pounds, and a former Towson University gymnast. She just became the first woman to reach American Ninja Warrior's finals.
