Running is the most commonly used form of movement for developing general aerobic endurance. It is a simple, natural movement, yet people can do it wrong.

Experiments done on athletes long ago (Nawrocka 1967) determined the optimal sequence for teaching a new sports technique: 1. Name the technique and give a brief description, including the key whys (yes, before a demonstration). 2. Demonstrate the whole technique at full speed. 3.
