No borders.
No need to own the feeling. Just resonance

"As teachers, we sprouted from the Dutch ITCCA branch, headed by Martin Klett, and are associated with Master Teacher Andreas Heyden, who has been teaching Tai Chi Chuan since the 1980s and leads the ITCCA Rheinland branch in Cologne, Germany."

"Over time, I also noticed a growing sense of mental resilience."

The fluid movements of the Tai Chi form and the mastery of one’s own body were the two things that drew me in most when I first encountered Tai Chi. I realized that this practice offered a way to relax and, in doing so, to handle daily stress with more ease. Over time, I also noticed a growing sense of mental resilience. I began training in 2002 at Martin Klett’s school in Amsterdam. Since 2005, I have taken yearly exams with Master Chu. In 2006, I started my own school. Alongside teaching various groups within the school, I continue to deepen my practice through workshops with Andreas Heyden in Cologne and with Master Chu in Italy.

"Tai Chi Chuan is about humanity & for everyone. No matter body type or age, diversity enriches the class."

Martial arts became part of my life through training in Pencak Silat — an Indonesian martial art. For over ten years, I trained intensively, often six hours a day, with plenty of Indonesian food to refuel. Physical toughness and long training hours simply belonged to that time. MONGOLIA 
Through my studies of Mongolian culture, a fascination grew for the music and nomadic dances of Mongolia, such as the biigee (biyelgee). These dances, deeply rooted in nomadic life, carry surprising martial elements and movements comparable to Tai Chi Chuan. The movements arise from practical attunement to the environment — emerging from riding, living closely with animals — and carry insights drawn from everyday activities, including the ancient art of archery. COLD 
I remember teaching a movement class to music teachers at a music college in Ulaanbaatar during a harsh winter. It was so cold that even indoors, water would freeze. To stay warm, we began moving playfully — slow martial movements inspired by Pencak Silat. It was an intuitive moment, where movement kept us awake, alive, and responsive to the conditions around us. HOW DO YOU MOVE A CAMEL? 
Looking back, this way of moving — shaped by daily necessity — seems closely connected to the way T’ai Chi Ch’uan evolved. The martial arts of the steppes and the Mongol-Chinese countryside seem to have gained their colors through animistic and everyday experiences: studying the stars, learning from animals, adapting to the wind across vast open fields, and asking practical questions such as: How do you move a camel? Rather than relying purely on abstract philosophical or spiritual systems, these concepts were rooted in action and practice. EVERY DAY LIFE? 
T’ai Chi Ch’uan, although rooted in older traditions and inspired by ancient spiritual concepts, feels to me like a martial art that has remained closely connected to the sensory world. It is an art of attunement — to the environment, the body, the earth, and the breath. HEALTH 
It was much later that I encountered T'ai Chi Ch’uan myself. By that time, after years without regular training and a long period spent in stressful conditions, even simple movement had become painful. When I closed my eyes, I could no longer visualize my body as a whole — as if something had been switched off. I knew that moving less and less was not an option. RECOGNITION 
Within T’ai Chi Ch’uan’s movement structure, I recognized something familiar. It offered a way to slowly rebuild my body awareness. It is remarkable how an art originally developed for martial purposes can also nurture health, healing, and connection. WHAT DO YOU SEE? 
In my earlier perception, Tai Chi had seemed slow, soft, even aimless — a naïve comparison to the theatrical and musical directness of Silat. But now, through practice, I see the richness and refinement of authentic Yang Style T’ai Chi Ch’uan. Not a single movement is without direction or intent. Movements conjure spatial, dynamic, and legendary images — echoing the landscapes from which they were born, in which I recognize a Mongol-Chinese cultural heritage. TRANSMISSION 
Master Chu’s generously shares the deep knowledge of the Yang family, and his students — many of whom have founded their own large schools — offer countless opportunities to explore the practice further. A “small” shift in attention can suddenly transform a movement you thought you knew into something completely different, light, and alive. CHANCE
 Choosing to train with the ITCCA was not a deliberate, calculated decision — it happened by chance, thanks to a friend's suggestion. In hindsight, it feels like great fortune. I began my training with Martin Klett in Amsterdam, and up to today I continue to train with Andreas Heyden (Cologne), while also attending seminars and examination sessions with Master Chu.
Since 2015, I have been teaching within the ITCCA. DIVERSITY One of the most beautiful things about T’ai Chi Ch’uan is that it belongs to everyone. No matter your age, your body type, or your previous experience, you can find your own way into the art. Diversity in the class — of age, shape, background — is not a barrier; it is an enrichment. It shows how soft strength reveals itself differently in each of us. HUMANITY For me, T’ai Chi Ch’uan is a practice of humanity. It reconnects us to something simple and enduring: movement, breath, attention, adaptability. It reminds us we are not apart from our surroundings — we move with them, through them, and as part of the living world.

Sandra Rensman is a dedicated Tai Chi Chuan instructor whose path from professional violist to internal martial arts practitioner reflects a lifelong fascination with the process of refinement. Whether in music or movement, she is inspired by the art of deepening — of working from a clear image or concept and allowing it to unfold, integrate, and resonate through physical space and presence. Originally trained as a violist, Sandra spent many years immersed in the world of classical music, where precision, sensitivity, and expression must be continuously honed. This discipline naturally led her to Tai Chi, a practice that mirrors musical artistry in its emphasis on flow, subtle awareness, and internal coherence. Her journey into Tai Chi began in London, where she studied Yang style within the school of Master Dong Zeng Chen. During this early period, she was particularly fascinated by the physical sensation of elasticity in the body — a subtle, spring-like quality that offered her a completely new way of connecting with her physical self. This experience opened up a richer sense of internal space, structure, and energy flow. Sandra’s pursuit of a more nuanced understanding brought her into the lineage of Master Chu King Hung, whose teachings on traditional Yang style Tai Chi emphasized rootedness, spiraling energy, and internal strength. Within this lineage, she studied with Stefan Diderich. To this day, she enjoys his teaching and his down-to-earth approach. What defines Sandra’s way of working is her love of exploring how things are built, how they function, and most importantly — how they feel. She enjoys discovering how seemingly small details have a powerful impact on the quality of movement and contact. This process demands attentiveness not just intellectually, but through embodied experience: spatially, physically, and energetically. Since becoming a certified teacher in 2018, she has brought this passion for refinement and inquiry into her teaching. In her classes, students are invited into a subtle, ongoing process of discovering structure, breath, intention, and alignment — just as in music, where each note is both precise and alive.

"It contains a truth that, really, should be shared from an early age."

Tai Chi Chuan has taught me one of the most essential lessons a human being can receive in a lifetime — a truth that, really, should be shared from an early age: the way of balance and awareness. It shows how to steady your actions, your thoughts, your emotions — so nothing is excessive, nothing is missing. Everything finds its right place. It heightens your awareness when you drift off-center, and gently brings you back to yourself. Of course, it teaches you how to fall, what it means to shrink inward — and in the face of life’s challenges, you learn how to stand. By doing not too much, not too little. Through this, I’ve found a way to live more clearly, and more joyfully. I started practicing tai chi chuan as I had been always fascinated by those slow and elegant movements resonating with awareness and power. Since the first classes I could feel the benefits of the qi gong and the tai chi form practice in re-aligning with the essential, both internally and externally. My path has so far led me to ITCCA, where I found an effective teaching method which gave me the opportunity to explore the multiple facets of this ancient martial art and grow by acquiring new perspectives in life.

Looking for a sport that suits me, I ended up at Tai Chi Chuan. It was recommended by a friend of mine. I took a trial lesson with Stefan, and it clicked. The way Stefan introduces it is very down-to-earth and well-paced, yet you immediately feel that it is part of a much larger whole that you are invited to explore. It is a beautiful art of movement: you learn to move purposefully and mindfully, softly yet resiliently. You seek calmness in movement and learn to yield to force instead of resisting it. At the same time, you are intensely engaged because it is, after all, originally a martial art that has been developed and passed down over time. How wonderful it is to be a part of that. I notice that practicing Tai Chi Chuan gives me energy and helps me learn to maintain focus better. What particularly fascinates me is that it’s all about the details that perfect the movements. It’s the small adjustments you learn and explore yourself that make the difference. It’s about exploring, experiencing, adjusting, learning from your teacher and other teachers in the ITTCA network of schools, and ultimately from Master Chu, with whom I took an exam this spring. In short, Tai Chi Chuan is a beautiful and inspiring journey where with every deepening step, you keep wondering what else there is to learn. The possibilities within this centuries-old art of movement are endless.

Tai Chi Chuan Long hand form -108

The Tai Chi Chuan form consists of three parts: Earth, Man, and Heaven. Learning the entire choreography typically takes around one to one and a half years. For beginners, we divide the form into smaller sections: Part 1 Form A – From the beginning to “Raise Two Hands” Form B – From the beginning to “One Hand – Ten Strokes” Part 2 Form C – From the start of the second part to “Cloud Hands” Form D – From the start of the second part to “One Hand – Ten Strokes” Part 3 Form E – From the start of the third part to “Golden Pheasant” Form F – From the start of the third part to “Return to Origin” Each posture in the Tai Chi Chuan form is, in essence, energetically complete. To prepare the body, students first learn how to find a balanced position by opening the joints (or meridians), both in stillness and in the transitions between postures. These positions are then tested with a practice partner to explore stability and balance. As training progresses, we test the “Internal Principles” and begin developing inner strength through dynamic partner work. Testing is done using a gentle, continuous push or pull. If muscular effort or resistance is required to maintain balance, the posture is not yet correct. More advanced practitioners eventually test energetically, where even the lightest touch reveals the quality of alignment and internal structure.
