Sandy Zimmerman just made history.

Not only is she the oldest woman to complete the American Ninja Warrior course, she also is the first mother to hit that buzzer.

“I wanna hit that buzzer for all of the moms out there, not just for me,” she said before her feat. “We so often put everything for us on the back burner.”

During Monday’s Seattle/Tacoma city finals, Zimmerman tackled every obstacle with confidence: the Barrel Roll, the Broken Bridge, the Lightning Bolts and finally the infamous Warped Wall.
