CUES 口令
Starting position: Side-lying, lower waist aligned with chair top. Bottom hand on pedal, shoulder over hand. Top arm/hand by side. Breathing: Exhale to laterally flex spine, top hand slides toward knee; inhale to return, drawing lower ribs in. Imagery: Body like an opened fan.
【起始位】侧躺，下方的侧腰对齐椅子上方。手放在踏板上，肩膀在手的上方。上方的手臂/手掌放在身体侧边。【呼吸模式】吐气时做脊柱侧弯动作，上方的手往膝盖方向滑动；吸气时回到起始姿势，往内收紧下段的肋骨。【想象】身体像一把拉开的扇子。
IMAGERY 意象
【Direct】While extending laterally, focus on maintaining maximum distance between the upper rib cage and the ipsilateral iliac crest, ensuring the lower ribs do not collapse toward the pelvis. Guide the atlas (C1) to continuously move away from the sacral center to maintain even intervertebral space. Keep both shoulders and ASIS sliding within the same vertical plane. 【Indirect】Taut Compound Bow: Imagine your body as a dense compound bow; the legs and pelvis are the steady grip, and the spine is the uniformly loaded bow limb, creating a fluid arc of tension. Sprouting Seedling: The body is like a sun-seeking seedling; the lower sit bones are roots deep in the soil, while the upper trunk traces a flexible growth path through the air. Vaulted Arch: Imagine lateral flexion as constructing a grand semi-circular vault; each vertebra is a precision-cut stone block, lining up seamlessly to support the structure. 【Space】Scraping the Dome Interior: Feel as if you are inside a giant transparent glass sphere; try to scrape the very top of the sphere's interior with your crown and fingertips, filling every inch of the arc. Infinite Gravity Line: Visualize a gravity line shooting from your fingertips to the horizon; during flexion, this line constantly pulls your body further, extending your radius in space. Vertical Screen Sandwiched: Imagine being sandwiched between two parallel vertical frosted glass screens; your chest and back must not touch either side, forcing motion strictly within the frontal plane. 【Feeling】Resilience of Heated Amber (Kinesthetic): Feel your spine made of warm amber; during flexion, it exhibits a dense, deep, and silky extensibility without abrupt breaks. Reed in the Wind (Kinesthetic/Control): Flexion is like a reed tilting in a breeze; the movement is light and rhythmic, maintaining high-frequency structural toughness within. Quiet Resonance (Auditory/Awareness): While holding at the limit, listen internally for a deep string resonance; feel the fascial tension reaching perfect frequency synchronization.
【直接】在向侧方延伸时，专注于保持上侧肋骨笼边缘与同侧髂嵴之间的最大距离，同时确保下侧肋骨不向骨盆塌陷。引导第一颈椎（寰椎）持续背离骶骨中心运动，维持椎间盘空间的均匀分配。保持双肩与髂前上棘（ASIS）始终在同一个垂直平面内滑动。【间接】拉满的复合弓：想象你的身体是一张致密的复合弓；双腿和骨盆是稳固的握柄，脊柱则是受力均匀的弓背，呈现出流畅且充满张力的弧线。破土的嫩芽：身体如同一株向阳生长的嫩芽；下侧坐骨是深扎在土壤里的根须，上侧躯干则在空气中划出一道柔韧的生长轨迹。古建筑的拱顶：将侧弯想象成建造一座宏伟的半圆拱顶；每一节椎骨都是精准切割的石砖，严丝合缝地排列成完美半圆。【空间】刮过圆顶内壁：感觉你正身处一个透明的巨型玻璃球内；尝试用你的头顶和指尖去精准地刮过球体最顶端的内壁，填满圆弧的负空间。无限延伸的引力线：视觉化一根从你指尖射向地平线尽头的引力线；侧弯时，这根线不断将你的身体向远方拉长。垂直的夹板屏风：想象你正被夹在两面平行的垂直磨砂玻璃屏风之间；侧屈过程中，你的前胸和后背严禁触碰到任何一侧的玻璃。【感觉】受热琥珀的韧性（动觉）：感受你的脊柱是由温热的琥珀制成的；侧弯时，它展现出一种致密、深沉且极其丝滑的延展性。风中的芦苇（动觉/控制）：侧弯的过程如同芦苇在微风中倾斜；动作带有轻盈感与随风而动的节奏，内部维持着稳定的结构韧劲。静谧的共振（听觉/觉知）：在侧弯到极限保持时，内心听听那声深沉的琴弦共鸣；感受全身筋膜张力在这一刻达到了完美的频率同步。
TACTILE CUES 触觉提示
Lightly pull above iliac crest to guide lengthening; hand on lateral ribs to guide lifting toward ceiling; lightly touch supporting shoulder to prevent excessive shrugging.
在髂嵴上方轻拉引导延展；手置于侧肋处引导向天花板方向隆起；轻触支撑手肩膀确保不过度耸肩。
PROGRESSION 进阶
P- increase range of motion; P- use chair only, no trapeze.
P-增加动作幅度；P-单用Chair椅子不用秋千床。
REGRESSION 退阶
