Do not think parts, think the unified whole conceptualize how the body works together as a link system. All training should be designed to enhance that linkage. Look for connections and relationships; do not get hung upon minutiae. All systems of the body work together all the time. There are no switches that turn energy systems off or on and there are no switches that turn muscles off and on. You cannot isolate and just train the muscular system or the nervous system, or any other system of the body for that matter, they all work together all the time to produce smooth efficient movement. Train and rehab the connections by using methods that promote linkage. Think of linking the ankle, knee and hip, to the shoulder, elbow, wrist and hand. This is the most effective means of staying on the “Functional Path” and being efficient. Training linkage and enhancing connections transfers to efficient movement, efficient movement transfers to improved performance.
