DALLAS -

A former college gymnast is becoming an Internet sensation for her historic performance on NBC's "American Ninja Warrior."

Kacy Catanzaro zipped through the finals course in Dallas on Monday's show, becoming the first woman to reach the show's finals in Las Vegas, which will air in August. Video of her performance online has become a viral sensation, even among those fans who say they hadn't watched the show before.

"Thank you ALL for the kind words and support! It means the world to me!" Catanzaro tweeted Thursday afternoon.

Catanzaro was a gymnast at Towson University in Maryland. At five feet tall and just 100 pounds, she is noticeably smaller than other competitors who climb, leap and swing their way through the warrior course.

After she finished her run Monday, her boyfriend, Brent Steffensen, scaled the outside of the scaffolding of the final tower to celebrate.

She says she hopes her popularity can serve as an inspiration to others who want to get fit.

"American Ninja Warrior" airs Monday nights at 9 p.m. on Channel 13.
