Kacy Catanzaro is only 5 feet tall and weighs only 100 pounds... but that didn't stop her from making history as the first woman to complete NBC's "American Ninja Warrior" course challenge.
Catanzaro is a former D1 gymnast for Townson University, and she was voted NCAA's Southeast Regional Gymnast of the Year in 2012. She proved her skill in the Dallas finals, which was aired this past Monday. The national finals in Las Vegas will be aired this coming Monday on NBC.
