Every runner should master conscious movement and the things happening inside his body.
This means that he should constantly observe and learn to feel and understand changes while moving. That would help him pinpoint the cause of pain or injury and prevent it while getting a better result.
The body's normal functioning demands our consciousness to check posture and how we sit, running, and walking. Some moves that we constantly perform unconsciously and automatically should also be observed and corrected. Again, we perform other movements actively - in sports and recreation or work (behind the conveyor belt, several hours of sitting at the computer, long drive…) - these require more of our energy, and more energy means more responsibility, which requires more attention. However, we can all see that more energy in athletes does not increase the attention to what they perform with this energy.
