Kình

Kình is organized, elastic muscle tone. It is not brute force and not rigid tension. In the manuals, Kình is the structural readiness that lets force travel without leaking, while still keeping the body supple enough to move quickly.

Core idea

• Too loose: force leaks and timing gets late.
• Too tight: joints lock and racquet speed dies.
• Just right: the body becomes a tensegrity-style conduit.

Why it matters

Kình is the bridge between martial-arts body logic and tennis stroke production. It supports GRF transmission, protects the joints during deceleration, and keeps the player stable under pressure.
