BURNSVILLE, Minn. - There's a group of teenagers in the Twin Cities that have formed a unique club to train for Ninja Warrior events.
The "Chalk Club" has been together for about a year and train at Conquer Ninja Gym in Burnsville.
The young athletes have been able to use the skills they've learned on the obstacle course events to help in other sports as well.
