In this episode we look at running and what makes good technique.

Running involves generating horizontal, vertical, and rotational forces. The primary goal is to maximize horizontal force and minimize the other two. Horizontal force is maximized by minimizing ground contact time, ideally by landing with the foot under the hips. 

However, this is difficult because the foot must land at the center of gravity. Leaning forward from the waist is a common mistake, as it promotes heel striking and increases ground contact time. Shoes facilitate this unnatural running style by absorbing shock, whereas barefoot running encourages a more natural midfoot strike. 

Learning to lean from the ankles instead of the waist helps maintain proper posture and minimizes center of gravity displacement. By practicing good posture and increasing cadence, runners can optimize their technique and minimize ground contact time.
