CUES 口令
Starting position: Supine, arms by sides, legs parallel at 45°, feet in loops, pelvis neutral. Movement: Inhale slightly bend knees; exhale legs arc back, sequentially rolling spine up to shoulder blades; inhale slight external rotation and bend knees until thighs parallel to floor; exhale roll spine down sequentially, finally extending legs to start. Imagery: Spine like a string of round pearls, lifted and lowered one by one.
起始位：仰卧，手在身体两侧，双腿平行伸直在 45 度角，脚在套环中，骨盆中立位。动作：吸气微屈膝；吐气双腿呈弧形往后，将脊椎分节卷起至肩胛骨位置；吸气微外旋并屈膝，直到大腿平行于地面；吐气将脊椎分节卷回到床面上，最后双腿伸出回到起始位。想象提示：脊椎像一串圆润的珍珠，一颗一颗提起再放下。
IMAGERY 意象
【Direct】On exhale, pull up and back from the pubis, guiding each spinous process to leave the carriage sequentially until the weight is supported by the shoulder girdle. During descent, keep the femurs fixed over the chest, focusing on letting the lower margin of the sternum touch the carriage first. Inhale at the top to increase posterior rib cage expansion, using internal tension to assist spinal elongation. 【Indirect】Flexible Bamboo Blind: Imagine your spine as a fine bamboo blind; when rolling up, each slat gathers steadily and equidistantly; when descending, it spreads out smoothly segment by segment like a hanging curtain. Folding Silk Screen: When frogging the knees, feel the body like a folding ornate silk screen, with the axis right at your hip joints. Inverted Vine: When rolling up, the legs are like vines climbing upward in the air, with upward energy provided by the core foundation. 【Space】Virtual Semicircular Track: Feel your toes tracing a giant, translucent semicircular track, ensuring the trajectory fills every inch of reachable space above the body. Diagonal Axis Reduction: When rolling up, strive to shorten the distance between the sternum and knees; when descending, let the crown and tailbone pull toward opposite far poles of the room. Filling Invisible Molds: Imagine a miniature arch bridge mold above the carriage; as you descend, try to let the spinal vertebrae fit perfectly into every groove of the mold. 【Feeling】Underwater Buoyancy: Feel as if you are in warm, buoyant water; the roll-up is not a forceful push but an effortless lift by a gentle current. Flowing Fine Sand: Imagine the inside of your spine filled with flowing warm sand; as you descend, the sand flows from the head toward the tailbone, bringing the vertebrae back to the carriage quietly and solidly. Silent Muting: Attempt to let the sound of the carriage returning dissolve completely into your breath, using ultimate silence as feedback for your precise eccentric control of spring tension.
【直接】吐气卷起时，从耻骨开始向上向后提拉，引导每一节棘突依次离开滑车，直到重量稳固地承托在肩胛带上。下卷时，保持大腿骨固定在胸口上方，专注于让胸骨下缘先行触碰滑车。在动作顶端吸气，增加胸廓后侧扩张度，通过内部张力协助脊柱延展。【间接】柔韧的竹帘：想象你的脊柱是一领精美的竹帘，向上卷起时，每一根细竹节都平稳、等距地收拢；下落时，则像帘子垂挂般一节节顺滑铺开。折叠的丝绸屏风：在收屈膝盖时，感觉身体像一面正在对折的华丽丝绸屏风，转轴就在你的髋关节处。倒置的藤蔓：卷起时，双腿如同在空中向上攀爬的藤蔓，由核心根基提供向上的能量支持。【空间】虚拟的半月形轨道：感觉你的脚尖正在勾勒一个巨大的、半透明的半月形轨道，确保轨迹填满了身体上方每一寸空间。对角线轴心缩减：卷起时努力缩短胸骨与膝盖的距离；下落时让头顶与尾骨向房间两端最远的极点无限对拉。填充隐形模具：想象滑车上方有一个微型拱桥模具，下落时尝试让背部脊椎严丝合缝地填满模具的每一处凹槽。【感觉】水底的浮力感：感受你正身处温暖且具有浮力的水中，卷起动作并非发力猛冲，而是被一股温柔的水流托举而上。细沙的流动：想象你的脊柱内部充满了流动的温润细沙，下落时细沙从头侧流向尾骨，带动椎体沉静、扎实地回到滑车。静谧的消音：尝试让滑车回位时的声音完全消融在呼吸中，用极致的静谧来反馈对弹簧张力的精准离心控制。
TACTILE CUES 触觉提示
Lightly touch spine to guide articulation; hands on pelvis to guide return to neutral.
轻触脊椎引导分节卷动；手放在骨盆上方引导回到中立位。
PROGRESSION 进阶
P- increase speed and control of roll; P- reduce support to increase core challenge.
P-增加卷动的速度与控制；P-减小支撑感增加核心挑战。
REGRESSION 退阶
R- Bridging as preparation.
R-Bridging（桥式）作为预备。
COMMON ERRORS 常见错误
Rolling up instead of back; lumbar initiating return instead of sequential spinal articulation; excessive spinal compression on neck.
