Freeze intensity 4/5

Why do I tense up under stress?

Stress tensing is involuntary muscle contraction triggered by adrenaline. Useful against cold or to absorb a hit, but useless against an attacker — it freezes movement.

Why it happens — the mechanism

Adrenaline contracts all striated muscles in 0.3 second via the sympathetic system. This general tetany prevents fluid movement. Shoulders rise, hips lock, knees stiffen. Side effect: post-stress shaking when the discharge releases.

How the Avikzar System answers it

The Avikzar System teaches 4-count breathing (4-4-4-4) when entering a tense situation. This activates the ventral vagal and breaks tetany in under 3 breath cycles.

Yehouda Avikzar (10th Dan) — Freezing isn't your fault — it's your biology. But not training after experiencing one is your responsibility.
