We build the foundation of real problem-solving by learning how to match symptoms to the structure that’s actually creating them. You’ll learn why pain location isn’t always the true source, and how different tissues express dysfunction in different ways. We break down the 10 key structures and introduce the concept of relative function—meaning the same symptom can mean something completely different from one person to the next based on their body, compensations, and physiology.

Pillar One of the AAFT framework, Physiology Build Type sets the baseline for how joints function, adapt, and recover. Before we talk about posture, pain, or performance, we have to understand what a body is built to adapt to. Largely influenced by genetics, build type determines how joints stabilize, range of motion, load absorption, and movement and recovery responses, allowing you to guide clients toward strategies that help them feel and function at their best.

Redefining build type recovery means restoring the structure the brain relies on for stability. Muscle Build recovery is metabolic and neurological, requiring glucose & nervous system restoration so muscles can actively stabilize joints. Fascial Build recovery is structural, requiring mechanical loading, hydration, and elastic restoration so fascia can provide passive stability. Recovery is complete when the brain can again trust its preferred system to create reliable joint position & feedback.

Structural dominance describes which tissue—muscle or fascia—the brain relies on most in a specific region to create stability and interpret position. While build type is global, dominance is local and can vary by joint. Muscle dominant areas stabilize through active contraction and neural drive, while fascia dominant areas stabilize through passive tension and elastic resistance, shaping force absorption, feedback, and compensation risk. This determines how brain protects and organizes movement

Pain is not just tension—it is often a signal of structural length and loss of positional certainty. This course teaches how the brain interprets lengthened tissue as unstable and threatening, leading to pain, guarding, and compensation. Learn to assess length dysfunction, restore joint certainty, and use targeted manual and movement strategies to reduce pain by improving structural feedback and stability.

Default position is the structural state your nervous system returns to when it is not actively thinking about movement. It reflects which tissues the brain trusts most for stability and where joint certainty exists or is lost. This course teaches how to assess default position through posture, tone, and movement patterns, and how it influences pain, compensation, and performance. Learn to identify structural priorities and restore joint certainty to improve function and reduce injury risk.

A precise 15-minute assessment uses the pillars to identify what the brain trusts for stability and where certainty is lost. By observing default position, build type, structural dominance, length dysfunction, and brain interpretation, you quickly find the true source of compensation and pain. This allows confident treatment decisions that restore joint certainty and improve nervous system trust without guesswork.
