The Wolfpack Ninjas, Meagan Martin, Brian Arnold, Ian Dory and Noah Kaufman, know they need to keep their skills on point to keep up with the American Ninja Warrior obstacles. That means training. Lots and lots of training.
One of their favorite places to test their limits is Earth Treks climbing gym in Golden, Colorado.
Check out some behind the scenes footage of the Wolfpack working out and showing off the guts and physical strength that keeps them as top Ninja competitors.
