Gymnast dominates American Ninja course that would break you in two

You could not do this. You think you could, but you could not.

This is Kacy Catanzaro, a former Towson University gymnast. She's five feet tall and weighs 100 pounds. And she just became the first woman to reach American Ninja Warrior's finals with this standout obstacle course performance.

Just imagine doing any of the multiple obstacles Catanzaro cruises through with little difficulty here. We'd break in half, we would.
