A Colo. Gym Owner Talks About Training For NBC’s ‘American Ninja Warrior’

Listen Now

For seven seasons, no one had ever managed to finish the course on NBC's "American Ninja Warrior." But last week, Coloradan Isaac Caldiero pulled off the feat, which culminated in a 70-foot rope climb with a 30-second time limit. Caldiero, an avid rock climber, trains at several gyms in Colorado that specialize in training specific to the obstacles that are found on the show. One of them is Urban Acrobatics in Thornton, Colorado. It's owner, Lorin Ball, spoke with Colorado Matters host Ryan Warner.
