CHANHASSEN, Minn. – At a small Crossfit gym in Chanhassen, 27-year old Chris Johnson is hard at work. But his workout isn't your typical routine.
"I'm doing it all including body weight workouts, weight training, yoga, and rock climbing," says Johnson. "Anything to get me 'ninja ready.'"
Johnson is competing in NBC's "America's Ninja Warrior." Last week, he was in Denver for the taping of the show's sixth season. The show brings together dozens of athletes from across the globe to compete in, what some call, the world's toughest obstacle courses.
"It's one of the hardest and most ridiculous things you could be a part of," chuckles Johnson, who lives in Waconia.
He's always enjoyed sports, but nothing like this.
"Two years ago I didn't care about fitness," says Johnson. "I look at what I'm doing now and am totally surprised."
Johnson is a middle school math teacher at Cologne Academy, a school that has caught the ninja-buzz.
"We should be talking math, but the students want to talk about the show. They're pretty excited."
The new season of "American's Ninja Warrior" airs Monday, May 26. Johnson has dedicated this journey to his grandfather who passed away in 2012.
