Tai Chi Lower Body Silk Reeling: The Foundation of Whole-Body Power

The following is an excerpt from my book Tai Chi Basic Training Manual, with additional context and internal links added for readers of this site.

In all my years of practicing and teaching Chen style Tai Chi, I have rarely heard lower body silk reeling explained clearly. Most instruction focuses on the arms and hands, which are the most visible part of silk reeling movement, while the legs are treated as a platform rather than an active participant. This is a fundamental misunderstanding of how silk reeling works, and it is the reason so many practitioners develop arm movement that looks like silk reeling from the outside but lacks the whole-body connection that makes it real.

Lower body silk reeling is not a supplement to the practice. It is the foundation. Until it is understood and developed, genuine whole-body power is not possible, because the power of Chen style Tai Chi originates in the legs and feet, passes through the waist, and expresses through the arms. If the lower body is not doing its part, there is nothing to express.

The 3 Principles of Tai Chi

Before getting into the mechanics of this exercise, it is worth grounding it in the principles that give it meaning. There are really only three principles that define Tai Chi as an art:

1. Use intention to guide your movement, not external force (Yi bu li)
2. Letting go of all physical and mental tension (Fangsong)
3. Continually spiraling full body movement (Chansijin)

This article focuses on the third principle, silk reeling, and specifically on how it manifests in the lower body. The other two principles are equally essential, and each one is covered in depth elsewhere on this site. For the complete picture of all three, see The 3 Principles of Chen Tai Chi.

What Silk Reeling Is

Silk reeling, chansijin in Chinese, describes Tai Chi’s continually spiraling whole-body movement. The name comes from the action of drawing silk thread from a cocoon: continuous, even, unbroken motion that neither jerks nor pauses. Every part of the body, arms, torso, and legs, demonstrates this spiraling motion simultaneously.

Silk reeling is not just an external movement pattern. On the outside we move in circles and spirals. On the inside, the chi or vital energy moves in the same circles and spirals. When the internal and external are in harmony, the practice becomes what it is designed to be: a health and martial art simultaneously, because the same principles that generate martial power also cultivate health. This is why some practitioners describe Tai Chi as a form of Qigong, because the continuous cultivation of healthy chi flow is present in every movement.

Why Lower Body Silk Reeling Is the Foundation

In Tai Chi it is vital to develop proper lower body structural alignment and silk reeling motion before expecting the upper body to produce genuine whole-body movement. Without the lower body foundation, the upper body cannot fully relax, and without that relaxation, internal skill cannot develop.

The tendency in practice is to focus on the arms and hands because they are what the observer sees. But the power and the connection that makes silk reeling real comes from the ground up. The legs and feet establish the root. The waist coordinates the whole. The arms express what the lower body generates. Develop the lower body first, and the upper body practice will transform.

There are subtle movements happening in the legs during silk reeling that are rarely explained clearly in instruction. Without understanding them, practitioners develop movement that is disconnected, unbalanced, and incapable of generating whole-body power. The step-by-step method below addresses exactly these subtle mechanics.

Practice With Full Intention

Before beginning, one important principle: everything described below must begin with intention. You must imagine and visualize this intricate series of coordinated motions as one whole before attempting to execute them. Tai Chi movement is not choreography learned part by part and assembled later. It is a unified internal vision expressed through the body. The clearer the internal image, the more coordinated the external movement will be.

Practice this exercise as a standalone daily practice until it is smooth and all elements are coordinated simultaneously. Then begin incorporating it into your basics, form, Push Hands, and self-defense applications. Do not rush this progression. The lower body foundation must be genuinely established before the upper body silk reeling is added.

1. Begin in Horse Stance

Feet 3 to 4 feet apart, turn toes outward slightly, bend knees 30 to 45 degrees, and sit down from the pelvis.

Cross the center of your palms, men place left hand first, women place right hand first, and place them on the lower stomach approximately 2 to 3 inches below the umbilicus.

Keep your body straight with the point at the very top of the head lifting up and the perineum sinking down, both points forming a straight line with gravity.

2. Shift to Right Bow and Arrow Stance

Weight 70% right side. Waist rotates to the right. Body raises up to top of arc. Legs silk reel and spiral in: right leg counterclockwise, left leg clockwise, producing the lifting and raising action. Knees compress toward each other. Heels grind outward.

3. Shift to Horse Stance

Weight 50/50. Waist rotates to front. Body sinks down to bottom of arc. Legs silk reel and spiral out: right leg clockwise, left leg counterclockwise, producing the sinking action. Knees expand away from each other. Heels grind inward.

4. Shift to Left Bow and Arrow Stance

Weight 70% left side. Waist rotates to the left. Body raises up to top of arc. Legs silk reel and spiral in: right leg counterclockwise, left leg clockwise, producing the lifting and raising action. Knees compress toward each other. Heels grind outward.

Practice the Lower Body Silk Reeling Daily

Practice shifting back and forth from Right Bow and Arrow Stance to Horse Stance to Left Bow and Arrow Stance continuously until the movement is smooth and all elements are coordinated simultaneously. This takes time and daily repetition. Do not expect to coordinate all components in the first sessions. Work on one element at a time until it is natural, then add the next.

Special Notes

1. Make sure both feet remain firmly on the ground throughout the movement.
2. In Bow and Arrow Stance, keep a slight bend at the extended knee. Do not lock it in full extension.
3. Make sure your shoulders stay directly in line with your hips and your nose stays in line with your umbilicus. There is no spinal rotation in this movement. The entire upper body moves as one piece from the waist and hips.
4. Grinding inward means imagining the points just lateral to the ball of each foot as the pivot point, with the heels pushing and rotating inward. In the second half of the movement the heels push and rotate outward. The heels are not literally grinding. They are pushing inward and outward in coordination with all other components of the exercise.
5. Learn this lower body silk reeling well before adding the arm silk reeling.

When you can coordinate all of these components together smoothly and comfortably, you will have a solid foundation for lower body silk reeling. At that point, begin applying the same principles to other stances and to form and Push Hands practice.

Checklist for Lower Body Silk Reeling

1. Shift side to side
2. Rotate waist
3. Downward to upward arc
4. Spiral legs
5. Open and close legs (knees)
6. Grinding heels

Use this checklist at the beginning of each practice session to verify all components are present before increasing the pace or adding complexity. When the checklist becomes automatic, you no longer need it consciously because the movement has been internalized.

Taking the Practice Further

The complete lower body silk reeling method, along with all the foundational upper body exercises and their integration into form practice, is covered in full in my Tai Chi Basic Training Manual. For those who prefer video instruction with step-by-step guidance through the complete basics curriculum, my Tai Chi Basics course walks through everything including the lower body silk reeling with the kind of detail that written instruction alone cannot fully convey.

Frequently Asked Questions

Why does lower body silk reeling feel so uncoordinated at first?

Because it is asking several parts of the body to do different things simultaneously in a coordinated pattern that most people have never attempted. The leg spiraling directions, the heel grinding, the waist rotation, the arc of the body, and the knee compression and expansion are all happening at once and must be coordinated by intention rather than executed sequentially. This is neurologically demanding and takes time. The correct approach is to practice each element separately until it is natural, then combine them one at a time. Expect several weeks of daily practice before the full coordination becomes smooth. That is normal and expected, not a sign that something is wrong.

What does grinding the heels actually mean in practice?

The grinding instruction describes a rotational pressure through the heel, not literal friction against the floor. Think of the point just lateral to the ball of the foot as a fixed pivot, and the heel as rotating around that pivot. Inward grinding means the heel rotates toward the midline of the body. Outward grinding means the heel rotates away from the midline. The actual movement is subtle and internal. The feet do not visibly slide on the ground. The pressure and rotational intention are felt inside the leg from the foot upward. It takes consistent daily practice to develop the sensitivity to feel this clearly.

How does lower body silk reeling connect to the upper body practice?

The lower body provides the root and the power source. The upper body silk reeling exercises, the single hand, double hand, and opening and closing exercises, express what the lower body generates through the waist and into the arms. When the lower body foundation is absent, the upper body exercises become arm exercises with no ground connection. When the lower body is properly developed, the arm movements carry the whole-body coordinated force that makes silk reeling genuinely therapeutic and martially effective. This is why the instruction is to learn lower body silk reeling well before adding the arm movement.

Is lower body silk reeling appropriate for people with knee problems?

Yes, with appropriate modification. The key alignment rules apply directly: knees must track over the toes and must never collapse inward. The stance depth, the degree of knee bend, can be reduced significantly in early practice without losing the essential quality of the exercise. Begin in a higher, more upright stance and allow the stance to deepen gradually as the knees respond to the practice. The spiraling and weight-shifting motion of lower body silk reeling is actually therapeutic for most knee conditions when practiced with correct alignment, because it circulates synovial fluid and distributes load evenly across the joint surfaces.
