1. CORE STRUCTURE:
The correct adult S-shaped structure that functions optimally
for human movement in Earth’s gravity.
2. CORE STABILITY:
The combination of highly strengthened/conditioned CORE MUSCULATURE & orthopedically correct CORE STRUCTURE from which the body most optimally & safely functions from.
3. ORTHOPEDIC:
The restoration & preservation of proper skeletal (spinal)
structure & function.
Maximizing core structure – part 2a.
QUESTION No. 1:
My CORE STRUCTURE consists of my skeletal bone/ vertebrae. HOW DO I make my CORE STRUCTURE stronger???
Maximizing core structure – part 2a.
Core structure is a lever arm
CENTER OF MASS & RESISTANCE FORCE
ANSWER TO QUESTION No. 1:
MECHANICAL ADVANTAGE - the ratio of the force exerted by a machine to the force applied to it. (Force exerted greater than force applied).

Interspinalis relaxed Interspinalis contracted Interspinalis chronically contracted (disc degeneration)
Interspinalis functions to extend the vertebral column.
The Interspinalis is chronically fatigued in the position of MECHANICAL DISADVANTAGE - it cannot carry out its function of extending the vertebrae.
