CUES 口令
Starting position: Supine, heels on foot bar, knees and hips bent approx 90°, pelvis neutral. Breathing: Inhale to lengthen; exhale to initiate from coccyx, rolling spine up into bridge; pause inhale; exhale to roll down sequentially to start. Imagery: Spine like a string of pearls being lifted one by one from a carpet.
起始位：仰卧，脚跟踩脚踏杆，膝髋弯曲接近90度，骨盆中立位。呼吸：吸气延伸；吐气从尾骨启动向上卷动脊椎起桥；停住吸气；吐气逐节下卷回到起始位。想象提示：脊椎像一串从地毯上逐一拎起的项链。
IMAGERY 意象
【Direct】In the starting position, feel the back of the head, posterior ribs, and sacrum pressing evenly into the carriage to establish neutral awareness. On exhalation, initiate from the tailbone, peeling the spine off the mat segment by segment until the knees, pelvis, and shoulders form a straight line. At the top, actively press the scapulae and heels of the hands against the carriage to organize shoulder stability and activate the latissimus dorsi. 【Indirect】Lifting Drawbridge: Imagine your body as a heavy drawbridge rising; the knees are powerful cables pulling the bridge deck (pelvis) diagonally upward while the piers (shoulders) remain absolutely stable. Pressing Piano Keys: During the descent, imagine the spine as a row of precision piano keys, pressing each key accurately and rhythmically from the neck down to the tailbone. Unfolding Scroll: When rolling up, feel the spine like an ancient scroll being slowly opened; as the pelvis lifts, every inch of texture spreads out evenly. 【Space】Diagonal Extension: Inhale at the peak, feeling the crown of the head and the knees growing infinitely toward opposite poles of the room, stretching the body into a taut diagonal line. Filling Negative Space: As the roll begins, actively let the lower back sink to fill the air gap between the lumbar spine and the carriage, ensuring no small segment is skipped. Lengthened Landing: When rolling down, try to land your tailbone closer to your heels than where it started, maximizing your axial length in space. 【Feeling】Warm Plasticine: Imagine the carriage surface covered in warm plasticine; as you descend, try to imprint a 'perfect spinal mold' with consistent depth and clear segments. Snap-Button Effect: When rolling down, feel the vertebrae like a row of invisible press studs snapping shut, with each bone making a crisp, solid 'click' as it meets the carriage. Melting Butter: On the exhale descending, let your sternum sink like melting butter into the depths of the carriage, making the space in the front of the chest soft and expansive.
【直接】在起始位，感受后脑勺、肋骨后方和骶骨均匀地压向滑车，建立中立位的觉知。吐气时，从尾骨开始启动，让脊椎由下至上一节一节地抬离垫子，直到膝盖、骨盆与肩膀连成一条直线。当身体到达顶端，通过肩胛骨和掌根主动抵住滑车平面，以此组织肩带的稳定并激活背阔肌。【间接】起重的吊桥：想象你的身体是一座正在升起的重型吊桥，膝盖处是强力的索引缆绳，稳稳地将桥面（骨盆）向斜上方拉起，而桥墩（肩膀）保持绝对稳固。按压的琴键：下落过程中，将脊柱想象成一排精密的钢琴键，按照由颈部到尾骨的顺序，将每一枚按键精准、有节奏地逐个按下。展开的卷轴：上卷时，感觉脊柱像是一个被缓缓打开的古老卷轴，随着骨盆的抬起，每一寸肌理都均匀地铺展开来。【空间】对角线延伸：在动作顶端吸气，感觉头顶与膝盖正朝着房间相反的两个极点无限生长，将身体在空间中拉成一根绷紧的斜长线。填补负空间：卷动开始时，主动让下背部下沉，去填满腰椎与滑车之间的空气间隙，确保动作没有跳过任何微小的节段。落点延长：下卷还原时，尝试让你的尾骨降落在比起始位置更靠近脚跟的地方，在空间中最大限度地拉长你的中轴长度。【感觉】温热的橡皮泥：想象滑车表面覆盖着一层温热的橡皮泥，下落时尝试在上面印出一个深浅一致、节段清晰的完美脊柱模具。按扣效应：卷下时，感觉脊椎像是在扣上一排隐形的衣领按扣，每一节椎骨接触滑车时都发出一个清脆、稳固的咔哒声。融化的黄油：吐气下卷时，让你的胸骨像融化的黄油一样向滑车深处凹陷沉降，让整个前胸的空间变得柔软且开阔。
TACTILE CUES 触觉提示
Lightly touch sacrum to initiate movement; slide hands along spine to guide articulation during roll down.
轻触骶骨引导起始动作；手沿脊椎两侧滑动引导分节下卷。
PROGRESSION 进阶
P- lower foot bar; P- straight leg variations; P- single leg variations; P- increase repetitions.
P-降低脚踏杆；P-双腿伸直变化；P-单腿变化；P-增加重复次数。
REGRESSION 退阶
R- perform partial range; P- light springs to increase stability challenge.
R-只做部分动作；P-轻弹簧增加稳定性挑战。
COMMON ERRORS 常见错误
Excessive posterior pelvic tilt at start/end; multiple vertebrae moving together; unnecessary pelvic shifting or lateral movement; excessive shoulder/neck tension.
