Our basic philosophy about running is that are a series of fundamental movements learned in the first ten years of life if circumstances are ideal. If those skills are weak, perfect running is impossible.
A determined adult will still pick up running in a diminished form, leading to injury and poor performance. Traditional coaching mostly focuses on training quantity, and sometimes emphasizes training quality. Unfortunately, they are only able to see the superficial effects of poor coordination, but not the deeper causes of poor running form.
As a result, most runners slip through the cracks; the deeper issues are never caught.
We believe nature reveals the deep issues in the process it uses to teach every person to run, starting from no ability at birth to great runners by age eight or so for those children lucky enough to be given good nutrition and good opportunity to move without interference by artificial devices.
