We suffer from an evolutionary postural trauma that we consider normal. We view verticality as our nature, when biologically speaking, it is a permanent state of exception.

It’s curious that we call ourselves terrestrial vertebrates, even though our deepest motor program still speaks the language of the ocean.

Coherence from external power arises where resistance to that power resonates.

Every position of superiority already carries within it the seeds of its own failure—a systemic paradox in which the maximization of power undermines its own foundation.

Silence in the system

What you say about using 20% effort is the key to understanding neural plasticity. This is called the “neuro-stacking” effect. If you apply too much force, you create noise in the system. The brain then only hears the noise, but no longer the fine information about joint position.

Soviet athletes used moderate exercises to draw extremely high-resolution maps in the brain. Someone who can balance perfectly with 20 kilos has a razor-sharp internal sense of where every vertebra is. Nelson Annunciato, an expert in neurobiology, often emphasizes that the brain only learns when it feels safe. Force–stretching is a lie detector. You can cheat your way into a stretch, but the nervous system registers the deception and shuts things down. The intelligent athlete offers the nervous system a partnership. He says: Look, I can not only reach this space, I can also control it.

The vertical as a permanent stress state

Humans are an unstable tower on a base that is far too small. That we never feel completely safe in the vertical is neurologically logical. The moment we stand up, the nervous system begins a high-performance task. The center of mass is high, the base of support is ridiculously small. The brain constantly scans: Are we falling?

If horizontal safety is missing, the nervous system tightens the reins. It stiffens the joints to replace missing neural control with mechanical stiffness. Our awareness doesn’t perceive this, because the brain filters out the fear. If we consciously felt the fear of falling all the time, we couldn’t hunt, gather, or work. So the fear is shifted into muscle tone. We interpret this as back pain or tension, but in reality it is a continuous signal of insecurity.

Force–stretching as a bridge to horizontal safety

This is where the circle closes with force–stretching and moderate loads. When you work at 20% effort, you give the brain exactly the horizontal competence it needs. It works like a safety net. Only once the net is in place does the brain allow the musculature to let go.

The nervous system cannot be suppressed permanently by willpower. In the end, it always wins through tone. We stop trying to correct the body and begin to calibrate the sense of safety.

First, one has to understand that our “operating system” evolved in the horizontal, and that our earlier models—and our tetrapod predecessors—moved very differently, namely in waves. The spine was originally a tool for propulsion in water. The lateral undulation of fish is the primordial form of our motor system. Even though we stand on two legs today, the heartbeat of that wave still pulses through our nervous system. Anyone who tries to understand the vertical as a rigid “stacking of bones” ignores 500 million years of evolutionary history.

Your concept of the horizontal aggregate describes the functional unit originally built for locomotion through space:

The wave (spinal wave): the engine. It distributes load and prevents pressure from accumulating at a single point (such as L5/S1).

The spiral (spiral force): evolution translated the linear wave into rotation. Our fascial lines are arranged in spirals to store and release kinetic energy like a spring.

The foot–calf complex: the endpoint of the chain that maintains contact with the ground—the catapult that directs the wave into the earth or retrieves it from it.

The problem for many practitioners is that they “freeze” the wave in the vertical. They become a column. Columns cannot transmit energy; they can only bear load until they break. When you transfer the wave drive into the vertical, everything changes. The body no longer stands statically—it “swings” itself into uprightness.

It is curious that we call ourselves terrestrial vertebrates, even though our deepest motor program still speaks the language of the ocean.
