HISTORICAL ROOTS OF THE FATAL KNEE

The knee technique, or Khao (sometimes referred to by the term Shittsui in specific regional lineages), is the primary lethal weapon of Muay Thai in the clinch range. Throughout the history of Thai Boxing, the knee has been regarded as a 'Fatal Assassin' because of its ability to deliver bone-crushing force to the torso, head, and thighs within a very short distance. This DVD is taught by Master Wu Bing, the Chairman of the Week Wushu Combat Research Committee and a 5th Grade Chinese Wushu expert. Master Wu Bing brings a unique analytical perspective to these ancient skills, explaining how the knee was developed for battlefield combat where fighters would seize an opponent and use the density of the kneecap to neutralize them. The Khao system is characterized by its suddenness and power, appearing and disappearing 'mysteriously' to bypass the opponent's guard, making it a critical focus for both martial historians and active combat practitioners.

BIOMECHANICAL ALIGNMENT AND SHORT POWER

Mastery of the Khao knee strike requires a profound understanding of structural leverage. Biomechanically, the knee strike is powered by the upward thrust of the legs and the simultaneous pulling motion of the arms, creating a 'collision' effect. Master Wu Bing demonstrates the various forms of the knee: the Khao Trong (Straight Knee), Khao Chiang (Diagonal Knee), and Khao Loi (Jumping Knee). Each variation requires specific alignment of the pelvis (Kua) to maximize kinetic output. The instruction emphasizes 'Short Power'—the ability to generate massive force (Fa-Jin) without a long wind-up. By curling the toes downward and tightening the calf against the thigh, the practitioner creates a spear-like striking surface. The DVD provides a step-by-step breakdown of how to integrate the 'Clinch' (Seizing) with the knee strike, showing how to manipulate the opponent's center of gravity to create a clear path for the blow.

COMBAT APPLICATIONS AND DEFENSIVE NEUTRALIZATION

In combat application, the knee is used with equal efficacy for offense, defense, and counter-attacks. Master Wu Bing illustrates how to use the knee to intercept an opponent's entry, particularly against aggressive punchers. The defensive application involves using the knee as a 'shield' to block low kicks or as a counter to a double-leg takedown. The tactical logic of the Khao system focuses on the 'Four Harmonies' of the clinch, where the practitioner’s hands, neck control, and knee strikes work as a single, cohesive unit. The DVD showcases drills for 'Adhere and Follow' within the clinch, teaching the practitioner how to sense the opponent's balance and deliver a knee strike at the moment of their greatest vulnerability. This transformation of Technical Routine into practical combat utility is what makes the Muay Thai knee system globally respected for its devastating efficiency.

INTEGRATED TRAINING AND INTERNAL FOCUS

High-level Knee Techniques require more than physical impact; they require a focused intent (Yi) and controlled breathing (Qi). Master Wu Bing explores the internal alchemy of the Khao system, teaching the practitioner how to remain relaxed and heavy in the clinch to avoid being thrown while maintaining the readiness to strike. This volume provides a comprehensive training progression, from basic knee-lifting drills to advanced jumping knee maneuvers. The training methodology emphasizes the 'Natural' movement of the joints and the preservation of the skeletal structure under pressure. For the global martial arts community, this resource offers an academic and technical archive of the Khao system, ensuring that its reputation for being 'impossible to defend' is grounded in rigorous practice and biomechanical precision. This masterclass is an indispensable guide for any serious martial artist looking to add the fatal power of the Thai knee to their technical repertoire.
