The cage changes everything. The cage is more than a physical structure, it's the material conditions that shape the behavior and performance of a fighter. Martial art movements, like any other movement, require room—just as generating power requires room. The cage allows for movement but also limits it. Even in the center of the cage, where there's open space, the cage still creates a sense of confinement and pressure. Since the focus of a fight is on the two competitors, the environment might seem trivial, but in reality, the environment shapes the fight. The environment shapes everything.
