Jessie Graff kicks butts and takes names for a living. The 34-year-old stuntwoman, who has appeared in movies like Wonder Woman and The Dark Knight and was the first woman to ever complete Stage 1 of American Ninja Warrior, turned her background in martial arts (she’s a black belt in Taekwondo), pole vaulting, and gymnastics into a career she is deeply passionate about.

“It all started when I fell in love with the circus at 4 years old,” Graff tells SELF. “I decided I wanted to climb everything.” And that’s pretty much what she does now for a living. Graff’s days are filled with fight scene training, flipping, jumping, climbing, and falling. On top of her job as a stuntwoman, Graff still competes on American Ninja Warrior.
