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.
