She has accomplished what many Navy Seals, Crossfit athletes and other fitness buffs have tried but failed to do: Complete the America Ninja Warrior obstacle course and qualify for the finals.
And to think that she is only 1.52m tall and weighs 45kg.
Last week, former Towson University gymnast Kacy Catanzaro became an overnight sensation for being the first woman to overcome the challenge.
She secured a spot in the finals in Las Vegas, where she will compete for the US$500,000 (S$621,000) prize money and the chance to clinch the title of American Ninja Warrior.
Such was her achievement that commentators on the show yelled: "She's not human! She's not human!"
Having been watched by millions on the broadcast of the show and online, the 24-year-old, who is from Belleville, New Jersey, said she has been blown away by the response to her feat.
"I knew a lot of women would be excited and inspired by it," Ms Catanzaro told USA Today.
She was a huge fan of the Japanese show Sasuke, which inspired the American version, while she was in university.
She then started training with boyfriend Brent Steffensen - who also competes on the show - last year.
Ms Catanzaro made it to the qualifying round last year, but did not finish the course, but has come back this year very strong and made history, Epoch Times reported.
One of the secrets to her phenomenal athleticism is a diet heavy in seafood, which allows her to be light and lean yet strong.
She told Fox News Sports: "We love fish - salmon or shrimp, scallops, definitely lots of seafood."
