CUES 口令
Starting position: Sit on chair facing away from pedals; knees straight, feet parallel to floor; maintain pelvis position, trunk tall, one hand reaches back to pedals, other hand reaches up. Breathing: Exhale press pedals toward floor; as pedals lower, gradually rotate trunk, bringing shoulders to greater angle; inhale return, pedals rise. Imagery: Body like a twisting auger slowly releasing.
【起始位】坐姿准备：坐在椅子上，背向脚踏板方向；膝盖伸直，双脚平行于地面；保持骨盆位置，躯干挺直，手往后延伸寻找脚踏板；另一手往上延伸。 【呼吸模式】吐气时将踏板往地板方向压；踏板往下时，身体逐渐地旋转，将躯干带到旋转状态，让肩膀面对更大的屏障/外展角度；躯干旋转回来时吸气，让踏板回到起始位置。 【想象】身体像一把正在拧紧并缓慢回弹的螺旋钻。
IMAGERY 意象
【Direct】Initiation: On exhale, recruit internal and external obliques to guide the thorax in a smooth horizontal rotation around the spinal axis. Pelvic Stability: Maintain even weight on both sit bones to ensure the pelvis remains neutral during the twist. Alignment: Keep shoulders depressed while the crown of the head spirals upward toward the ceiling. 【Indirect】Double-X Elastic Bands: Imagine a resilient 'double-X' elastic structure within your torso, storing and distributing spiral energy evenly as you rotate. Rotating Lighthouse: View your spine as a bright lighthouse; the base (pelvis) is firmly embedded in rock while the upper beam (thorax) sweeps slowly across the sea. Infinite Light Axis: Imagine your arm as an axis of light extending infinitely from the center of your chest through your fingertips into the void. 【Space】Filling Room Corners: During rotation, imagine your thorax expanding in all directions, reaching to fill every distant corner of the room. Bucket-Handle Widening: Feel the ribs widening laterally and posterolaterally like 'bucket handles,' creating a broad dynamic circumference. Passing Through an Air Door: Imagine your body moving through a heavy door of air, using the strength of your back and lateral ribs to push through the space. 【Feeling】Unfolding Silk (Tactile/Texture): Feel the large chest muscles like warm silk being slowly pulled apart, releasing tension into a deep stretch. Lubricated Facet Joints (Kinesthetic): Imagine each breath flushing and lubricating the spinal facet joints, making every micro-slide as smooth as an oiled surface. Thick Syrup Resistance (Kinesthetic): The twist feels like moving through thick syrup, with every inch of rotation met by a uniform, quality resistance for total control.
【直接】启动动力：吐气时通过腹内、外斜肌的协同募集，引导胸廓围绕脊柱轴心顺滑地进行水平面旋转。骨盆稳定：保持双侧坐骨在椅子表面均匀承重，确保骨盆在扭转中维持中立位。对位组织：旋转时保持肩膀下沉，感受头顶持续向天花板方向螺旋式向上生长。【间接】双X形弹力带：想象躯干内部有一个坚韧的“双X”形弹力带结构，随着扭转，交叉的力带正在积蓄并均匀分配螺旋能量。旋转灯塔：视脊柱为一座明亮的灯塔，底座（骨盆）稳稳嵌入礁石，上层的光束（胸廓）缓慢且全方位地扫过海面。无限延伸的光轴：将手臂想象成一根向外无限延伸的光轴，从胸腔中心一直穿透至指尖外的虚空。【空间】填满房间角落：在扭转时，想象你的胸廓正在全方位向外膨胀，试图去触碰并填满房间远处的每一个角落。水桶把手的拓宽：感受肋骨在水平面上像“水桶把手”一样向侧方及斜后方拓宽，创造宽阔的动态圆周。穿过空气之门：想象你的身体正穿过一扇厚重的空气之门，用背部和侧肋的力量去均匀地推开周围空间。【感觉】拉开的绸缎（触觉/质感）：感受胸前大肌群像正在被温热并缓慢拉开的绸缎，在旋转中逐渐释放紧绷感。润滑的小面关节（动觉）：想象呼吸在冲刷并润滑脊柱小面关节，让椎骨的滑动像在涂抹了油脂的表面般顺畅。浓稠糖浆的阻力（动觉）：扭转的过程就像在浓稠糖浆中移动，每一次推开和回旋都伴随着均匀而有质感的阻力。
TACTILE CUES 触觉提示
Instructor observes pelvis staying neutral (not rotating); lightly touch chin to prevent jutting forward.
导师观察其骨盆是否维持中立（不随旋转偏移）；轻触下巴提醒不要过度前顶。
PROGRESSION 进阶
P- finish in Teaser position.
P-以 Teaser 姿势结束。
REGRESSION 退阶
Adjust sitting position; mount from side near pedals.
调整坐姿位置（Mount 动作建议从椅子靠近踏板的一侧开始）。
COMMON ERRORS 常见错误
Scapular elevation; humeral head protrusion; pelvic rotation; legs dropping; head dropping; chin jutting; rib flaring/protrusion; excessive cervical rotation/lateral flexion.
肩胛上提；肱骨头往前顶；骨盆旋转；腿往下掉；头往下掉；下巴往前顶；肋骨外翻/往前顶；颈椎过度旋转与侧屈。
PRECAUTIONS 注意事项
Shoulder/neck conditions, acute spinal conditions, severe osteoporosis (avoid large rotation).
肩颈部疾患、急性脊椎病症、严重的骨质疏松（避免大幅度旋转）。
