CUES 口令
Starting positions: Hamstring II: Stand behind chair, feet about one foot from chair, spine flexed, hands on pedals. Kneeling Cat: High kneeling on chair, knees near front edge. Breathing: Inhale prepare; exhale contract deep abdominals, press pedals to floor; inhale return, legs still. Imagery: Spine like a cat arching its back when startled.
【起始位】Hamstring II：站在万能椅后方，脚距椅子约一脚宽，脊椎弯曲，手放在踏板上。Kneeling Cat：高跪姿于椅子上，膝盖接近椅子前缘。【呼吸模式】吸气预备；吐气深层腹肌收缩，将踏板压向地板；吸气回到开始位置，双腿不动。【想象】脊柱像一只受惊吓后高高弓起背部的猫。
IMAGERY 意象
【Direct】Hamstring II: Exhale to recruit deep abdominals and press the pedal toward the floor, keeping the thighs and torso parallel to the ground at the lowest point. Maintain spinal length through axial elongation of the crown. Kneeling Cat: Initiate a head nod and articulate down through the thoracic and lumbar spine, keeping hips and knees vertical over the floor. On inhale, feel the spine restack segmentally back to an upright position. 【Indirect】Pearl Necklace (Hamstring II): Imagine your spine as a string of pearls unfolding one by one during the descent. Startled Cat (Kneeling Cat): Imagine you are a frightened cat, arching the center of your back toward the ceiling against gravity. Wave and Serpent (Kneeling Cat): The spinal movement should be as fluid as a wave or a swimming snake, full of organic vitality. 【Space】Entering Vast Space (Hamstring II): As you move downward, imagine entering a larger dimension rather than compressing yourself. Filling the Void (Kneeling Cat): Imagine your back arching into the space behind you, filling the entire negative space to create a maximal curve. Opposite Poles (Kneeling Cat): Feel the crown and tailbone extending infinitely in opposite directions, creating maximum internal space. 【Feeling】Peeling Velcro (Tactile): During spinal articulation, feel the vertebrae 'peeling' away like Velcro or off memory foam with a crisp, rhythmic feedback. Heavy Syrup Damping (Kinesthetic): While pressing the pedal, feel the air as viscous as heavy syrup, requiring a uniform and deep force to 'push through.' Cork Floating (Kinesthetic): Control the pedal's return as if it were a cork rising steadily from the bottom of a pool, rather than snapping back.
【直接】Hamstring II：呼气时深层腹肌收缩，将踏板压向地板方向，保持大腿和躯干在最低点时平行于地面。通过头顶的延伸来保持脊柱的长度。Kneeling Cat：从头颈部开始点头下卷，带动胸椎和腰椎逐节向下，保持髋部和膝盖垂直于地面，不要向后坐。吸气回卷时，感受脊椎一节一节地堆叠回到直立位。【间接】珍珠项链（Hamstring II）：想象你的脊柱是一串珍贵的珍珠项链，随着下压动作逐节展开。受惊的小猫（Kneeling Cat）：想象你是一只受惊吓的猫，正对抗地心引力将背部中心向天花板顶起。波浪与游蛇（Kneeling Cat）：脊柱的移动要像波浪或游动的蛇一样流畅，充满生命力。【空间】进入更宽广的空间（Hamstring II）：在向下移动时，想象你正进入一个更宽广的维度，而不是把自己压缩起来。背部填满空间（Kneeling Cat）：想象你的背部正在向后方拱起，去填满身后的整个负空间，创造极致的弧度。相反方向的极点（Kneeling Cat）：感受头顶与尾骨向相反方向无限延伸，在体内创造最大的空间。【感觉】剥离魔术贴（触觉）：在脊柱卷动时，感受椎骨像从记忆海绵上逐节“撕开”或剥离魔术贴（Velcro）一样，带着清脆的节奏感。厚重糖浆的阻尼（动觉）：在推下踏板时，感受空气变得像厚重的糖浆一样粘稠，需要用均匀且深沉的力量去“推开”阻力。软木塞漂浮（动觉）：控制踏板回弹时，想象它像软木塞一样从水底平稳地“飘”上来，而非猛然弹起。
TACTILE CUES 触觉提示
Instructor lightly touches thoracic spine to guide even spinal flexion; gently pull coccyx diagonally back to stretch hamstrings.
导师在胸椎段轻触引导均匀的弓背动作；轻拉尾骨引导其朝向斜后方以伸展腘绳肌。
PROGRESSION 进阶
P- use lighter springs to reduce support and increase challenge.
P-使用较轻的弹簧以减少支持并增加挑战。
REGRESSION 退阶
R- place a cushion under pedals to reduce range of motion.
R-在踏板下加衬垫以减少活动范围。
COMMON ERRORS 常见错误
Hinging at one spinal segment; shoulder shrugging; losing spinal flexion; hips sitting back.
在单节脊椎凹折；耸肩；失去脊柱前弯屈曲；髋部往后坐。
PRECAUTIONS 注意事项
Acute lumbar disc herniation; inability to kneel (for kneeling version).
急性腰椎椎间盘突出；膝关节无法跪地（针对跪姿版）。
