DENVER -- If you haven't heard of "parkour," you're not alone. It is an intense activity that is a growing trend.
Parkour involves jumping, tumbling, running and climbing in urban and natural environments.
People use the body's momentum to propel themselves safely through real-world obstacle courses.
And now there are gyms that provide parkour training. Learn more about Apex Movement here.
