CUES 口令
Starting position: Side-sit, one leg aligned with shoulder rest, other knee aligned with inside edge of carriage. Spine neutral. Breathing: Inhale to lengthen spine; exhale to push carriage away from foot bar, arm making C-shape overhead; inhale hold, exhale return. Imagery: Body sliding sideways between two glass panels.
起始位：横坐，一腿与肩靠对齐，另一腿膝盖与滑板内侧边缘对齐。脊椎中立位。呼吸：吸气脊椎延伸；吐气拉滑台推离脚踏杆，手臂在头上方形成C形；吸气维持，吐气回到起始位。想象提示：想象身体在两片玻璃之间做侧向滑动。
IMAGERY 意象
【Direct】As you push the carriage away into a side bend, keep the contralateral sit bone pressed evenly into the carriage mat without lifting as the body moves. Let the center of the crown grow continuously toward the horizon along the arc of the spinal lateral flexion, ensuring the length of the back of the neck matches the thoracic curve. On exhalation, feel the lower rib cage margin actively contracting inward to create more internal space for the spine's lateral bending. 【Indirect】Venetian Blinds: Imagine your ribs are a set of precision blinds; during the side bend, the segments on the upper side open layer by layer to greet the sunlight, while the lower segments overlap smoothly. Longbow: The torso is like a fully drawn longbow; the core is the taut string supporting the spine as it forms an arc filled with elastic energy toward the side. Resilient Fishing Rod: Imagine the spine as a highly flexible fishing rod, with the tip (crown) drawn by an invisible force toward the upper diagonal, carving a perfect curve in space. 【Space】Virtual Dome: Feel as if you are inside a giant transparent glass dome; during the side bend, your fingertips and spine must glide precisely against the inner wall of the dome. 2D Slice: Imagine being trapped between two extremely narrow frosted glass walls; your lateral flexion must stay strictly within this plane, allowing no forward leaning or posterior rotation. Touching the Skyline: Try to reach your fingertips toward the farthest horizon where the ceiling meets the side wall, letting your body's tension fill the dimensions of the room. 【Feeling】Warm Pulled Taffy: During the side bend, feel the fascia of the lateral waist like warm taffy being slowly pulled apart, becoming longer, more supple, and possessing a silky sense of elongation. Anchor Effect: Feel your pelvic floor like a heavy anchor sunken into the deep sea, firmly rooted in the carriage mat, giving you absolute confidence for the upper body's free movement. Passing Breeze: Upon inhaling to return to an upright position, listen to the sound of air moving between the ribs, feeling a cool breeze dispersing every bit of pressure between the vertebrae.
【直接】在推开滑车侧弯时，保持对侧坐骨始终均匀地压在滑车垫子上，不随身体移动而抬起。让头顶中心点顺着脊柱侧屈的圆弧方向持续向远方生长，确保颈部后侧的长度与胸椎弧度一致。吐气时，感受下方肋骨笼边缘主动向内收缩，为脊柱的侧向弯曲创造更多的内部空间。【间接】百叶窗：想象你的肋骨是一排精密的百叶窗；侧弯时，上方的一侧窗片为了迎接阳光而层层打开，而下方的一侧窗片则柔顺地重叠在一起。长弓：躯干如同一张拉满弦的长弓，核心是那根紧绷的弦，正支撑着脊柱向侧方形成一个充满弹性能量的弧面。柔韧的钓竿：将脊柱想象成一根极具韧性的钓竿，尖端（头顶）被斜上方不可见的力量牵引，在空间中划出一段完美的曲线。【空间】虚拟穹顶：感觉你正身处一个巨大的透明玻璃穹顶内部，侧弯时，你的指尖和脊柱必须精准地贴合着穹顶的内壁滑动。二维切片：想象你被困在两片极窄的磨砂玻璃墙之间，你的侧弯动作必须严格保持在这个平面内，不允许身体有任何前倾或后旋的偏移。触碰天际线：试着用你的指尖去触碰天花板与侧墙交界处那条最远的地平线，让身体的张力填满整个房间的维度。【感觉】温热的拉丝糖：侧弯过程中，感受侧腰的筋膜像被慢慢拉开的温热拉丝糖，变得越来越纤长、柔韧，且带有一种丝滑的延展感。船锚效应：感受你的盆底肌像一个沉入深海的重型船锚，稳稳地扎在滑车垫子里，带给你上半身自由挥洒的绝对信心。微风拂过：吸气回到直立位时，听听空气在肋骨间穿行的声音，感觉清凉的微风正吹散脊椎间的每一丝压力。
TACTILE CUES 触觉提示
Lightly touch lateral ribs to guide side bend; hands on iliac crests to ensure pelvis stays level.
手轻触肋骨侧向引导推开；手放在髂嵴确保骨盆不随之抬起。
PROGRESSION 进阶
P- add spinal rotation/counter-rotation during side bend; P- increase spring tension.
P-在侧弯时加入脊椎旋转/反向旋转；P-增加弹簧重量。
REGRESSION 退阶
R- reduce range of motion; R- sit on small box (Moon Box) if hips tight.
R-减少活动范围（ROM）；R-由于髋部紧张可坐在小盒子（Moon Box）上。
COMMON ERRORS 常见错误
Shifting trunk instead of side bending; rib flaring; contralateral sit bone lifting off carriage; scapular elevation; head dropping or jutting forward.
用躯干的侧移取代侧弯；肋骨外翻；对侧坐骨抬离滑板；肩胛上提；头垂下或前突。
PRECAUTIONS 注意事项
Osteoporosis (rotation variation contraindicated).
骨质疏松症（侧屈旋转变化式需禁忌）。
