A mother of three from Spokane, Washington, made history last night on the hugely-popular, fun-to-watch show "American Ninja Warrior" on NBC.

The show was taped Mother's Day weekend in the Tacoma Dome. It was the first time the show was ever shot in the Pacific Northwest.

What made it amazing was 42-year-old Sandy Zimmerman nailed the course like a boss and is the first Mother to compete and make it through!

Watch her amazing run!! GO SANDY GO SANDY!

Know what else is interesting? Famous NW weather forecaster Majestic Storm had Mrs. Zimmerman as her elementary school PE teacher!
