WHY A HIERARCHY?

The body doesn't experience your habits separately.
Most fitness knowledge is organized by topic. Training lives over here. Nutrition over there. Sleep, mobility and conditioning become separate specialties.

But the body does not experience them separately.

The hierarchy organizes them by dependency. It asks which layer establishes the conditions required for the next one to work.

THE SIX LEVELS

Build from the bottom up.
Each level has a different job. Together they form one model of physical development.

L0 · Framework

Principles before methods.

The mental operating system beneath every decision. Learn how to diagnose, adapt and eventually author the system yourself.

L1 · Regulation

Build the capacity to adapt.

Sleep, stress, nervous system state and hormones establish the biological environment in which everything above either works or gets constrained.

Read Regulation →

L2 · Fuel

Supply what adaptation requires.

Energy and nutrients provide the raw material for performance, repair, body composition and growth.

Read Fuel →

L3 · Integrity

Earn the right to load the movement.

Mobility and movement quality determine whether force can be expressed through a structure prepared to tolerate it.

Read Integrity →

L4 · Stimulus

Give the body a reason to adapt.

Training is deliberate stress. Its value depends on the capacity established by the levels beneath it.

Read Stimulus →

L5 · Engine

Build the capacity beneath performance.

The aerobic and anaerobic systems determine how long, how hard and how repeatedly physical output can be sustained.

DIAGNOSTIC USE

When something breaks, move downward.
Do not automatically attack the level where the symptom appears.

A stalled lift does not prove that more training is required. Poor recovery does not automatically mean the program is wrong.

Start low. Find the first layer that is not doing its job. Fix the bottleneck before adding complexity above it.

Read the doctrine in sequence.
Begin with Framework and move upward.

The point is not to memorize six categories. It is to learn a way of thinking that eventually makes the categories unnecessary.
