NOTE:
Many may dismiss the movements in the below videos as impractical, but they are classical forms designed to build foundational principles—not how Grandmaster Decker truly fought. I share them to honor and preserve his legacy. Simply learning the forms and some drills does not teach how he actually fought.

Decker’s fighting method was fast, powerful, brutal, and decisive. Sometimes deceptive (attack by drawing which he termed ‘possum’). Elements of Decker’s fighting method are reflected in Kosho Ryu Kempo, Hanshi Bruce Juchnik’s system, particularly in their focus on fighting centers and related principles such as the octagon. However, Decker’s method stands out as notably more aggressive.

I had the privilege of learning Grandmaster Decker’s fighting method firsthand. While RAT Synthesis does not include the traditional aspects of his system—such as horse training, forms, and other classical practices, many of which were poetry in motion—we fully integrate his practical fighting Gung Fu and Pagua (Bagua) into Tier 3 of the RAT Synthesis system.

For a detailed look at our approach, see the blog post: DENIS DECKER FIGHTING GUNG FU – RAT SYNTHESIS TIER 3.

Grandmaster Decker was both feared and loved by many martial artists he encountered. His skill was undeniable—he could end fights with advanced practitioners in seconds. But as he aged and evolved, a deeper gentleness emerged. He became more generous, more compassionate—and in the end, he was loved even more than he was feared.

Hanshi Bruce Juchnik—renowned martial artist, head of the Kosho Ryu Kempo system, and close friend of Grandmaster Decker—offers his reflections on their relationship and Decker’s legacy.

Cynthia Rothrock is an acclaimed American martial artist and actress, widely celebrated for her groundbreaking work in martial arts cinema and for paving the way as a female action star.

Cynthia was taught by Grandmaster Denis Decker in the late 1960s or 1970s. Below is a Facebook post she shared, featuring a photo of the two together when she was a young martial artist.

From what I understand, Grandmaster Decker and Cynthia were both training in Eagle Claw Kung Fu with Leung Shum in Pennsylvania during the 1970s. That was quintessential Denis—he thrived on connecting with other masters like Leung and exchanging knowledge. In this way, he remained unrestricted by any single martial arts style, yet he developed his own unique system known as Chi Ling Pai®.

Grandmaster Denis Decker was not merely a martial artist; he was a visionary whose approach to martial arts became a revolutionary force within the discipline. His unique Gung Fu was an extraordinary fusion of profound internal power, adaptable combat strategies, and deep philosophical insight, blending the body, mind, and spirit into one cohesive system.

Decker’s genius lay in his ability to integrate real-world application with explosive technique and mental agility, creating a martial art that was as strategic as it was powerful. His mindset was built on these cornerstones, each reinforcing the other to form a system that transcended conventional martial arts.

Key Points in Denis Decker’s Mindset and Strategy

1. Real-World Application: Denis Decker didn’t just create a martial art for the sake of tradition; he forged a system for survival. His approach was founded on the belief that martial arts must be tested in real combat. He emphasized practical techniques that could be utilized in the most challenging, high-stress environments. Unlike many traditional schools that were bogged down by rigid forms and theory, Decker’s Gung Fu was designed for adaptability. Every technique was a tool for survival, tested under pressure, shaped by the chaos of real-world application.
2. Adaptability and Fluidity: In Decker’s system, rigidity was the enemy. His students were not taught to memorize patterns; instead, they were trained to feel the flow of combat, to adjust and adapt seamlessly to the ever-changing dynamics of a fight. Decker’s gung fu emphasizes fluidity and natural body mechanics, ensuring that practitioners can respond to any situation, any opponent, and any environment. By cultivating fluid movements and intuitive responses, Decker’s system made practitioners unpredictable and virtually impossible to counter. Denis Decker exemplified creativity in martial arts by spontaneously creating new forms, showcasing his genius and innovative approach to Gung Fu.
3. Internal Strength and Energy: Where many martial artists focused on brute strength, Decker took the opposite approach. He tapped into the ancient art of internal energy, or chi, which became a central theme of Decker’s gung fu. Through controlled breathing and specific exercises, Decker’s system taught practitioners how to harness their internal power, using this energy to enhance their movements and strikes. The result? A martial artist whose strength was not limited to physical muscle but was magnified by the profound energy of chi, enabling them to strike with immense power while remaining grounded and centered.
4. Explosive Power with Minimal Effort: Decker understood the value of efficiency in combat. His teachings prioritized using minimal force to generate maximum effect, a concept that is crucial for overcoming opponents who may be larger, faster, or more aggressive. Instead of relying on brute force, Decker Gung Fu practitioners learn to deliver devastating strikes that are quick, powerful, and direct, allowing them to neutralize threats without wasting energy. This principle aligns with the internal energy philosophy, where strength isn’t solely about muscle but also about the seamless application of focused power.
5. Mental Agility and Focus: The mind is as important as the body in Decker’s Gung Fu. Denis Decker’s teachings stressed the importance of mental clarity and focus under pressure. He believed that mental agility—staying calm, sharp, and aware—was essential not only in combat but in life. Practitioners of his gung fu are trained to remain strategic and composed, able to adjust on the fly and adapt to opponents who may be faster, stronger, or more aggressive. This mental focus gives practitioners an extraordinary edge, as they can read their opponents and respond with pinpoint accuracy.
6. Self-Examination and Continuous Growth: One of Decker’s most profound beliefs was that martial arts, like life, is a journey of constant growth. He emphasized self-examination as a path to mastery, urging his students to reflect on their performance, learn from their mistakes, and continuously improve. This commitment to growth extended far beyond the dojo, creating individuals who were not just skilled martial artists, but individuals deeply committed to personal development. The philosophy of Decker’s gung fu, then, is not merely about fighting—it’s about becoming a better person every day.
7. Emphasis on Deception: The strategic mind of Denis Decker understood the power of deception. In combat, being predictable is a fatal flaw, and Decker’s system emphasized the use of feints, baits, misdirection, and unexpected angles. Decker called this Possum. Practitioners learned not only to strike but to outwit their opponents, making their movements unpredictable and disorienting. This mastery of deception was a crucial part of Decker’s gung fu, elevating the combatant from mere fighter to a true strategist, capable of turning the tide of battle with a single well-placed move.
8. The Importance of Teaching: Beyond his personal skill, Denis Decker was deeply committed to the art of teaching. He didn’t just want to create skilled fighters—he wanted to create well-rounded individuals, capable of mastering both combat and life. His philosophy was rooted in empowering others, sharing his knowledge, and building a community of like-minded individuals. The Denis Decker gung fu method wasn’t just about combat techniques; it was a school for life, shaping individuals into leaders, warriors, and thinkers.

Conclusion

Denis Decker’s Gung Fu represents a legacy of genius that goes far beyond the realm of martial arts. His system is a fusion of body, mind, and spirit, designed to unlock the potential of every individual. Through its emphasis on adaptability, internal strength, mental agility, and strategic deception, Decker’s gung fu offers a blueprint for personal and martial mastery.

Decker’s philosophy teaches us that true strength is not just about physical might but about the power of adaptability, strategy, and inner calm. His contributions to martial arts have inspired countless students to live, fight, and grow with strength, purpose, and clarity.

Through his gung fu, Decker gave the world not just a martial art, but a way of life.

Denis Decker once said, “Martial arts is about love.” At first, I misunderstood. But over time, I realized it was profound. Love is why we teach. Love is why we fight. Love is why we endure. One family.
