Kacy Cantanzaro, First Woman to Complete ‘American Ninja Warrior!’ [Video]

This is just insane! "American Ninja Warrior" contestant Kacy Cantanzaro became the first woman to complete the competition!

I have been watching this show since the days of G4, and what this woman can do to this crazy course is just impressive.

Watch the video below and have your body cringe because of how strong and flexible Cantanzaro is! She does show boat a little bit, but she deserves to after this!
