Watch ‘Supergirl’ Stuntwoman Jessie Graff Make ‘American Ninja Warrior’ History

You have to see it to believe it.

Stuntwoman Jessie Graff made American Ninja Warrior history Monday night, becoming the first woman to complete the super-tough Stage 1 Finals course.

Graff–who finished fourth out of eight competitors–is best known for her stunt work on Supergirl and Agents of S.H.I.E.L.D, but her obstacle course-slaying run is undoubtedly her most badass achievement yet. 

Just watch the whole video above if you don’t believe us. 

The American Ninja Warrior finals pick up again next week, but in the meantime, there’s even a LEGO version of Graff’s historic run to tide you over until then. Because why not?
