* **Ultimate Independence:** Just as local files free you from software lock-in, calisthenics frees you from equipment lock-in. It requires nothing but your own bodyweight (pushups, pullups, squats). * **Direct Relationship:** It removes the abstraction of gym machines, forcing a direct understanding of your own balance, strength, and physical reality. * **Existential Duty:** Ango views the human body as a finite vessel for experience. He believes we have a duty to use our limbs and senses to their fullest extent while we are alive. Calisthenics is the physical manifestation of that agency—rejecting consumerism in favor of raw, self-sufficient capability.
