 Incorporating the shoulder blade (scapula), breastbone (sternum), clavicle, upper arm bone (humerus), and the chest cage (ribcage)  

Incorporating the shoulder blade (scapula), breastbone (sternum), clavicle, upper arm bone (humerus), and the chest cage (ribcage) is essential for developing smooth, integrated body mechanics in Tai Chi push hands or other internal martial arts practices. These parts must function harmoniously to maintain structural integrity, enable efficient energy transfer, and ensure relaxation without stiffness. Let’s break down how to integrate these body parts:

1. Understanding the Key Areas:

• Clavicle (鎖骨): Acts as the bridge between the shoulder blade and the sternum, stabilizing and guiding the shoulder’s movement. It rotates during arm movements, and its position affects shoulder mobility and chest stability.

• Upper Arm Bone (Humerus): The upper arm bone connects the shoulder joint to the forearm and hand. The humerus must remain relaxed yet aligned with the torso, allowing for energy transfer from the legs and waist without local tension.

• Shoulder Blade (Scapula): Provides the foundation for the arm’s movement and is crucial for maintaining alignment and absorbing or issuing force.

• Breastbone (Sternum): Forms the central support of the chest and plays a key role in stability, posture, and breath control. It also helps manage the opening and closing of the chest, impacting energy circulation.

• Chest Cage (Ribcage): Protects vital organs and supports the breathing process. Proper chest alignment and flexibility are essential for maintaining the central axis (中定) and ensuring that movements are rooted in the lower body rather than localized in the chest.

2. How These Areas Work Together:

To maintain relaxed, connected movement in Tai Chi push hands, you must integrate these areas in a way that allows them to support each other without unnecessary tension. Here's how you can incorporate each part:

2.1 Clavicle and Shoulder Blade Integration:

• Clavicle-Shoulder Blade Relationship: The clavicle should move in coordination with the shoulder blade, but excessive tension in the clavicle or shoulder can disrupt the smooth movement of the arm. When you push or pull in push hands, ensure the clavicle is relaxed and follows the shoulder blade’s natural rotation. Think of the shoulder blade as the base from which the arm extends, and the clavicle as the "guide" that ensures a smooth connection between the arm and torso.

• Relaxed, Fluid Movements: Practice exercises where you focus on maintaining a relaxed shoulder girdle, allowing the clavicle to float and rotate naturally as the arms extend or retract. The clavicle should remain aligned with the shoulder and sternum, without jutting forward or pulling back excessively.

2.2 Upper Arm and Shoulder Blade Connection:

• Arm Relaxation: In push hands, the upper arm (humerus) should always remain relaxed and connected to the shoulder blade. The shoulder blade provides the support, while the arm moves freely without carrying its own tension. This allows energy to flow from the legs, through the torso, and into the arms.

• No Local Power: The goal is to avoid using "local" arm strength to push or pull. Instead, allow the movement to originate from the waist, guided by the alignment of the shoulder blade and humerus. The upper arm and shoulder blade should work together like a flexible, unified lever, transmitting force efficiently without breaking structure.

• Exercise: Practice lifting and lowering the arms while keeping the shoulder blades and humerus connected, ensuring that no tension accumulates in the shoulder joint. The movement should be smooth and initiated from the lower body and waist, not the shoulders.

2.3 Breastbone, Clavicle, and Chest Cage Alignment:

• Central Axis (Zhong Ding, 中定): The breastbone and chest cage are part of your central axis. Maintaining proper alignment between the breastbone and clavicle ensures that the upper body remains stable and doesn’t collapse or arch forward. The chest should neither puff out nor cave in but should be relaxed and expansive to allow free breathing and a rooted stance.

• Opening and Closing the Chest: The opening and closing of the chest (开合) is crucial in Tai Chi. This involves subtle movements in the breastbone and chest cage. When "opening" the chest (during an inhale), the breastbone lifts slightly, allowing the clavicles to rotate slightly upward. When "closing" the chest (during an exhale), the breastbone gently relaxes downward, allowing the shoulders to remain soft and connected to the torso. This movement is subtle but helps maintain energy circulation and proper structure during push hands.

2.4 Chest Cage, Breathing, and Qi Circulation:

• Relaxed Chest Cage: The ribcage should remain relaxed and flexible. Excess tension in the chest cage can block energy flow and disrupt your central axis. Deep, relaxed breathing (using the diaphragm) helps keep the chest cage open and free. This allows energy to flow from the lower body to the upper body without getting stuck or dissipated in the chest.

• Energy Flow (Qi Movement): When the chest cage, clavicle, and breastbone are properly aligned, and the breathing is deep and relaxed, the qi (energy) can flow smoothly through the body. In push hands, this connection ensures that you remain stable and connected to your root, and the force you generate is well-channeled.

3. Training to Integrate These Components:

Here are some training methods that will help integrate the clavicle, shoulder blade, upper arm, and chest cage:

3.1 Standing Meditation (Zhan Zhuang, 站樁):

Standing meditation is an excellent way to develop awareness and integration of these body parts. Focus on aligning the clavicle, breastbone, and shoulder blades while maintaining relaxation throughout the chest cage and upper arms. The key is to stand upright without any tension, ensuring that your central axis is aligned.

3.2 Push Hands with Attention on Relaxation:

When practicing push hands, emphasize relaxation and structure. Pay attention to the movement of your shoulder blades, clavicles, and upper arms. Ensure that the clavicle moves fluidly with the shoulder blade but doesn't become tense or over-engaged. Allow the breastbone to stay aligned with the torso without collapsing or puffing out.

3.3 Silk-Reeling Exercises (Chan Si Gong, 纏絲功):

Silk-reeling exercises help develop spiral movement and the coordination of different parts of the body. Focus on how the upper arm bone, shoulder blade, and clavicle move in spirals during these exercises. The chest should remain open but relaxed, with energy flowing smoothly from the ground to the arms.

3.4 Wall Alignment Exercises:

Stand against a wall with your back flat against it. Slowly raise and lower your arms while maintaining contact between the wall and your shoulder blades, clavicle, and upper back. This exercise helps you maintain alignment between the clavicle, breastbone, and shoulder blade, preventing the upper body from over-engaging during movement.

4. Key Points to Remember:

• Relaxation is Key: Excessive tension in the shoulder blades, clavicle, or chest cage disrupts energy flow and structural alignment. Focus on relaxation and connected movement.
• Integration: The shoulder blades, clavicle, breastbone, and chest cage should move in coordination without isolated tension. This ensures fluidity and stability during push hands.
• Structural Alignment: Keep the breastbone aligned with the central axis. Don’t let the chest cave in or puff out excessively.
• Energy Transmission: Power and energy in push hands should be generated from the ground, transmitted through the torso, and into the arms through a relaxed and integrated body structure.

By integrating these body parts in a relaxed, coordinated way, you will improve your push hands skills and develop a deeper connection to your root and energy.
