The 3 Principles of Chen Tai Chi

Most exercise systems have a lifespan. You lift weights in your twenties and thirties, your joints start to complain in your forties, and by your sixties the activity that was supposed to keep you healthy is the thing causing you pain. Yoga plateaus. Running destroys knees. Even swimming, one of the gentlest forms of exercise, becomes difficult as the shoulders age.

There are 3 main principles/elements of Chen tai chi that make it different from every other movement system, and they are the reason practitioners get better with age rather than decline. These are not philosophical abstractions or poetic metaphors. They are practical, physical skills that you develop through daily practice.

I have been practicing since 1969, more than 57 years, and I am more capable now than I was at 40. That is not an accident. It is the direct result of these three principles working together in my body every single day.

Understanding these principles intellectually is the beginning. Embodying them takes years of dedicated practice under qualified guidance. But understanding them clearly is the essential first step, and that is what this article is for.

Why Chen Style Tai Chi Must Fulfill Two Functions

Before we discuss the three principles, it is important to understand what they are designed to accomplish. Chen style tai chi is first and foremost a martial art. And a genuine martial art must fulfill two functions — not one, not three, but two specific functions — for your entire lifetime:

1. A martial art must support your health and facilitate healing. Not just when you are young and resilient, but progressively and increasingly as you age.
2. A martial art must be effective for self-defense. Not just as a young person with fast reflexes and strong muscles, but as a mature practitioner whose power comes from something deeper than physical strength.

Most exercise systems fail at both of these requirements over time. They are effective for health and fitness within a narrow window of physical peak,  and they rely entirely on muscular strength and speed for any martial application, which means they decline as the body ages.

The three principles of Chen tai chi solve both problems simultaneously. They describe a way of moving that becomes more powerful, more healthy, and more effective with every year of practice. This is why I teach them as the foundation of everything. Not as advanced concepts to aspire to, but as the basic operating principles from day one.

The 3 Principles of Chen Tai Chi

Every movement in Chen style tai chi – every posture, every transition, every application – is an expression of these three principles working together. Learn to understand them separately first, then discover how they unify into a single, integrated way of moving.

Principle 1: Use Intention to Guide Movement, Not External Force

This is the most important of the three principles and the one that takes the longest to genuinely understand. The instruction is deceptively simple: when practicing tai chi, your mind directs your qi, or vital energy, and your qi moves your body. You never resort to brute muscular force.

To understand why this matters, consider how you normally move. Every physical motion begins as a thought — a neurological signal from the brain to the muscles. But in most physical training, that signal is essentially: “contract this muscle hard, move this limb fast.” The mind gives a command and the muscles execute it through force. The mind and body are connected, but the connection is crude. More like a general giving orders to soldiers than a conductor leading an orchestra.

In Chen tai chi, we train something qualitatively different. The intention, what the Chinese call “yi”, becomes refined to the point where it can direct the flow of qi through the body with precision. The qi, in turn, moves the physical body. The result is movement that is simultaneously softer and more powerful than muscular force alone can produce. A beginner cannot feel this. After years of practice, it becomes the most obvious thing in the world.

I trained extensively under Grandmaster Wang Xi’an, one of the legendary “Four Buddha Warrior Attendants” who brought authentic Chen style to the world in the 1980s. What I witnessed in his movement cannot be explained by muscle mass or athletic conditioning alone. A man in his seventies demonstrating power and speed that defy what the body should be capable of at that age. This is intention at work. This is what the first principle produces when it is genuinely developed.

How to Develop Intention in Practice

The development of intention begins with attention. During tai chi practice, your awareness is fully engaged on exactly what you are doing in each moment. Not thinking about tomorrow’s schedule or last night’s conversation, but rather fully present with every tiny detail of every movement. Whether you are raising your hands, shifting your weight, or turning your waist, your complete focus is on the quality and internal experience of that movement.

This sounds simple. It is extraordinarily difficult. Most of us spend our days in a state of divided attention. Doing one thing while thinking about something else entirely. The practice of tai chi is, at one level, a daily training in the ability to be fully present. This is why practitioners consistently report improvements in mental clarity, focus, and the ability to handle stress. The mental training is inseparable from the physical training.

With consistent practice over time, the connection between mind and body deepens progressively. Movements that initially required conscious effort become integrated at a deeper level. New subtleties emerge that were invisible before. This process does not plateau. It continues to deepen for the entire lifetime of practice. This is what makes tai chi genuinely interesting after fifty years. There is always more to discover.

Principle 2: Letting Go – Complete Relaxation of Body and Mind

The second principle is what the Chinese call fangsong, or “letting go”. This means releasing every form of tension from your body and your mind. Not just the obvious tension of tight muscles, but the habitual, chronic, largely unconscious bracing and holding that most modern people carry as a constant background condition of their lives.

As a Doctor of Chiropractic with 35 years of practice, I have put my hands on thousands of bodies. What I found consistently, is that the vast majority of people are carrying far more tension than they realize – in their shoulders, their hips, their jaw, their hands, their lower back. This tension is not a response to immediate physical demand. It is chronic. It is habitual. And it is, from the perspective of both Western medicine and traditional Chinese medicine, a primary driver of pain, dysfunction, and accelerated aging.

In traditional Chinese medicine, tension is understood as the obstruction of qi flow through the meridians. Where qi flows freely, the body heals and maintains itself. Where qi is blocked by tension, pain and sickness develop over time. The second principle of Chen tai chi addresses this directly. Not through massage or manipulation or medication, but through the cultivation of the ability to consciously release tension from within.

What Letting Go Actually Means in Practice

When we begin tai chi, we are what I describe as “ten parts yang, zero parts yin” — all tension, no softness. The body has been conditioned by years of effort-based movement to default to muscular bracing as its primary strategy. The entire journey of Chen style practice is the gradual, patient process of undoing this conditioning. Layer by layer, year by year.

The practice instruction is simple: during every moment of practice, take inventory. Scan your body continuously. Do you feel tension in your shoulders? Let it go. Tension in your lower back? Let it go. Tension in your hands, your jaw, behind your eyes? Let it go. Not by forcing relaxation — that is a contradiction — but by bringing awareness to the tension and allowing it to release.

This is why correct structural alignment is so important in tai chi. When the body is properly aligned with gravity — weight distributed correctly, joints stacked naturally, spine neither rigid nor collapsed — the muscles can genuinely let go because the skeleton is supporting the body’s weight. Tension is often the body’s compensation for misalignment. Fix the alignment and the tension has no reason to be there.

The health benefits of developing genuine fangsong are profound and well-documented. Reduced chronic pain, improved circulation, lower blood pressure, better sleep, enhanced immune function… These are the consistent reports of practitioners who develop real relaxation through years of practice. This is not relaxation as passive collapse. It is relaxation as an active, cultivated skill: the ability to be completely at ease while fully engaged.

Principle 3: Silk Reeling — The Continuous Spiral Movement of the Whole Body

Silk reeling, or “chan si jin” in Chinese, is the physical hallmark of Chen style tai chi and the principle that most visibly distinguishes it from every other style of tai chi and every other movement system in the world. It refers to the continuous, spiraling, whole-body movement that flows through every posture and transition in the Chen style form without interruption.

The name comes from the traditional craft of unwinding silk from a cocoon. The thread must be drawn out continuously, smoothly, and at a consistent velocity. Too fast or too jerky and the thread breaks; too slow and the silk tangles. This quality — continuous, smooth, connected, and flowing in one unbroken thread from the feet through the legs, waist, spine, arms, and fingers — is what silk reeling produces in the body.

How Silk Reeling Works in the Body

When silk reeling is correctly developed, every joint in the body participates in every movement. Nothing moves in isolation. The power generated by the legs and ground travels through the ankles, knees, hips, spine, shoulders, elbows, and wrists in sequence, amplifying at each stage until it expresses itself in the hands. This is the internal power, or ” jin”,  that experienced Chen style practitioners develop and that cannot be replicated by muscular force alone.

The spiraling quality means that every movement in Chen tai chi follows an arc or a circle rather than a straight line. This is not decorative, it is biomechanically profound. Straight-line movements create force that can be met and blocked by an equal or greater straight-line force. Circular and spiraling movements redirect incoming force, neutralize it, and dissolve it. This is why silk reeling is so effective for self-defense — not because it creates more force, but because it makes force irrelevant.

Silk Reeling and Joint Health

From a health perspective, silk reeling is one of the most therapeutically valuable movement patterns that exists. The continuous gentle rotation of every joint in the body — hips, spine, shoulders, wrists, knees, ankles — acts as an internal pump for synovial fluid, the lubricating fluid that nourishes joint cartilage. Joints that are moved in straight lines and angles, the pattern of most conventional exercise, compress and release unevenly. Joints moved in spirals and circles receive consistent, even lubrication throughout their full range of motion.

This is why practitioners of Chen style tai chi consistently report improvement in arthritic joints, recovery from joint injuries, and the maintenance of full range of motion well into advanced age. The silk reeling movement is not just exercise for the muscles. It is medicine for the joints. I have seen students arrive with chronic knee pain, hip pain, and shoulder restrictions that conventional medicine had been unable to resolve, and watch those conditions improve steadily through consistent silk reeling practice.

How the Three Principles Work Together

Understanding each principle separately is important. Understanding how they function as a unified whole is essential.

Intention without relaxation produces focused but tense movement. The mind is engaged but the body is bracing, which blocks the flow of qi and limits both power and health benefit. Relaxation without intention produces collapse. The body lets go of tension but loses structure and the ability to generate or direct power. Silk reeling without both intention and relaxation is just external rotation, the spiraling shapes without the internal quality that gives them meaning.

When all three are present simultaneously — when intention is guiding movement, when the body is genuinely relaxed and open, and when silk reeling is connecting every part into a single flowing whole — something qualitatively different begins to happen. The movement takes on a quality that practitioners describe variously as flowing, alive, connected, or internal. It feels different from the inside. It looks different from the outside. And it produces health and martial benefits that none of the three principles can produce independently.

This integration is the work of a lifetime. It does not happen in weeks or months. It deepens progressively over years and decades of consistent daily practice under qualified guidance. This is not discouraging. Rather it is the most exciting thing about the practice. A discipline that continues to reveal new depths for the entire duration of your life is a rare and extraordinary gift.

The Three Principles in Daily Practice

In every training session, whether you are practicing foundation exercises, the solo form, silk reeling, or push hands with a partner, these three principles are the reference point. Not as a checklist to run through mentally, but as a quality of attention and physical presence that you are continuously cultivating and refining.

The instruction I give my students is this: never allow your practice to become mechanical. Never practice on autopilot. Every repetition of every movement is an opportunity to go deeper into intention, to release more tension, to refine the quality of the silk reeling. The moment practice becomes rote — something you do rather than something you are fully present with — you stop developing and start merely maintaining.

This is the difference between someone who has practiced tai chi for twenty years and someone who has genuinely trained for twenty years. The first person has repeated the same movements ten thousand times. The second person has used those ten thousand repetitions to go progressively deeper into the three principles. The difference in skill, health, and quality of movement between these two practitioners is vast.

Study well. Practice daily. And if you have questions about these principles or want to experience them directly, I welcome you to explore our online private instruction or join me for a class, workshop, or retreat where these principles come alive in the context of intensive, in-person training.

Frequently Asked Questions About the Principles of Chen Tai Chi

Which of the three principles is most important?

Intention, the first principle, is the foundation. Without the mind directing movement with genuine focus and awareness, neither relaxation nor silk reeling can develop to their full potential. However, the three principles are inseparable in practice. Developing one deepens the others. Think of them less as a hierarchy and more as three facets of a single gem.

How long does it take to develop these principles?

The first principle, intention, begins to develop within the first months of consistent daily practice. You will notice your focus and mind-body connection improving relatively quickly. The second principle, or “letting go”, takes longer, typically years, because it requires undoing deeply ingrained patterns of chronic tension. The third principle, or “silk reeling”, develops progressively throughout a lifetime of practice. There is no ceiling. Masters with fifty years of practice are still refining their silk reeling.

Can I develop these principles practicing on my own without a teacher?

Solo practice is essential. Daily repetition is how these principles become embodied. But without a qualified teacher who can observe your practice and give you direct feedback, it is very difficult to know whether you are developing genuine intention, genuine relaxation, and genuine silk reeling, or simply performing the external shapes of the movements. A good teacher accelerates development dramatically and prevents the reinforcement of subtle errors that can persist for years undetected.

Are these principles unique to Chen style tai chi?

All styles of tai chi share the first two principles to varying degrees. Silk reeling, the third principle, is specific to Chen style and is the clearest physical distinction between Chen style and the other major tai chi styles. It is present in Wu Hao style in a modified form, but the full development of chan si jin as a whole-body spiraling energy is the unique contribution of the Chen family system.
