Internal Power (内劲 / Nei Jin)
Definition: Internal Power (内劲, Nei Jin) is power generated from whole-body coordination, proper alignment, deep relaxation, and the integrated transmission of force from the ground through the body’s kinetic chain. It is fundamentally different from Li (力) — localized muscular strength.
Where Li uses isolated muscle groups and is easily resisted, Nei Jin draws power from the entire body acting as a unified structure. The force originates from the feet, is directed by the waist, and expressed through the hands — a transmission chain requiring Rooting, Central Equilibrium, and Song (relaxation) at every link.
Relationship to Other Concepts
- Jin (劲) — the broader category of trained force; Nei Jin is the internalized, highest expression of Jin
- Fa Jin (发劲) — the explosive release of this stored internal power
- Silk Reeling — the spiral mechanism through which Nei Jin is generated and transmitted
- Internal Martial Arts — the three arts (Taiji, Xingyi, Bagua) whose training methods specifically cultivate Nei Jin
