She stands just 5 feet tall, and weighs 100 pounds, but don't underestimate Kacy Catanzaro. The former Towson University gymnast just became the first woman ever to qualify for the 'American Ninja Warrior' final!

Known as one of the most amazing physical challenges for any athlete to complete, American ninja warrior has seen it share of male and female competitors who couldn't beat the obstacle course. Kacy Catanzaro has become the first woman to get past the  “warped wall” obstacle, in which competitors must get a running start to scale the 17-foot curved wall, according to CBS.

Kacy is headed to Las Vegas for the ultimate challenge – to climb Mount Midoriyami, a 70-foot steel structure.

And I thought 'Wipe Out' was tough!

Good luck, Kasey!
