American Ninja Warrior has become a pretty big hit for NBC and has created some celebrities among its "Ninja" competitors. Probably none bigger than the 5 foot tall, 100 pound Kacy Catanzaro.
Kacy made her name when she became the first woman to ever make it up the warped wall and is the only woman to complete a city finals course. And earlier this week she began training at the WWE performance center.
Where this leads, who knows. But Kacy is definitely a hard worker and is used to overcoming great odds. So, we wouldn't be surprised to see her in a WWE ring one day. Best of luck Kacy!
