How to run: whether it is long-distance running or trail running, whether you want to run faster or want to have the proper running form to get rid of your runners knee, you will learn more than you anticipated from the 20+ pages here.
You will learn how Posture Running will help you have fewer injuries, run with less effort, run faster at a given effort, be able to run more miles a week, etc.
Which running form should I learn: Chi Running, Natural Running, Pose Running, Posture Running, or one the dozens of unnamed running forms? This website will compare all these running techniques.
Why is it called Posture Running? Just like in other sports, like swimming and golf, movement starts with your core. Your core is often defined as beneath your neck down to and including your pelvis. Get that right first, and it then allows and encourages your appendages (arms and legs) to move the right way.
