CUES 口令
Starting position: Supine, shoulders and head on carriage, trunk suspended over springs. Hands on shoulder rests, elbows soft, feet on foot bar hip-width, knees bent. Breathing (initiated from coccyx): Inhale to extend hips and knees, pushing bar. Exhale to lower spine from coccyx. Inhale to bend knees, letting carriage return. Exhale to articulate spine up from coccyx to start. Then reverse direction (initiated from ribs). Cue: Roll up and down like a wave.
【起始位】仰卧，肩膀与头在床台上，躯干悬空在弹簧上方。手放肩托上，肘关节不锁死，双脚踩脚棒与髋同宽，膝盖弯曲。【呼吸（由尾骨带动）】吸气：髋与膝关节伸展，脚推杆。吐气：由尾骨带动脊椎下降。吸气：膝盖弯曲，让滑板拉回。吐气：由尾骨开始，脊椎一节一节卷动回到起始位置。之后反方向（由肋骨带动）练习。【提示】像海浪一样卷起落下。
IMAGERY 意象
【Direct】While pushing the carriage open, keep the humeral heads (shoulders) flat against the mat, allowing the sacrum to sink vertically toward the springs until you feel a distinct stretch in the front of the thighs (femurs). On exhale, pull up and in from the pubis, guiding the pelvis to curl toward the feet until the lumbar spinous processes touch the carriage edge segmentally. On inhale, apply even pressure through the heels to the footbar, guiding the pelvic center vertically toward the ceiling. 【Indirect】Ferris Wheel Cabin: Imagine your pelvis as an independent cabin on a Ferris wheel; during the push and pull, the cabin maintains its smooth, rounded trajectory. Folding Beach Chair: The body is like a folding beach chair being opened; the chair surface (trunk) extends far out when pushed, and the hinges (hips and spine) fold the structure precisely toward the center when returning. Kelp in Deep Sea Swells: The trunk is like a deeply rooted piece of kelp; the spinal undulation follows the 'ocean currents' of the spring tension in an extremely flexible and resilient arc. 【Space】Bottomless Canyon: As the pelvis sinks below the springs, imagine a bottomless virtual canyon beneath the carriage; let your tailbone explore deep into the canyon. 3D Cylindrical Wall: Feel as if you are moving inside a giant transparent cylinder; your body trajectory must precisely brush against the top and bottom of the cylinder. Diagonal Oppositional Axis: As the carriage opens, feel the crown and both knees extending toward two completely parallel diagonal lines in the room. 【Feeling】Warm Wax Block (Kinesthetic): Imagine your spine is made of warm, plastic wax; during the down-roll, feel each vertebra becoming silky and soft due to the heat, spreading perfectly against the carriage edge. Aftershock of a Guqin (Kinesthetic/Auditory): While holding at the peak (bridge position), feel the whole body like a just-plucked string, maintaining a low-frequency, dense, and stable internal tension resonance. Silent Water-Cutting (Auditory): Attempt to make the carriage glide on the tracks like a blade cutting through water; use this ultimate silence as feedback for your precise eccentric control of spring tension.
【直接】在将滑车推开时，保持肱骨头（肩关节）平贴于垫子，允许骶骨垂直沉向弹簧，直到感受到大腿前侧（股骨）的明显拉伸。吐气时，从耻骨开始向内向上提拉，引导骨盆向足部方向卷动，直到腰椎棘突逐节贴近滑车边缘。吸气时，通过脚跟向脚踏杆施加均衡的压力，引导骨盆中心垂直升向天花板。【间接】摩天轮的座舱：想象你的骨盆是摩天轮上的一个独立座舱；在滑车推拉的过程中，座舱始终保持其圆润的轨迹。折叠沙滩椅：身体如同一把正在打开的折叠沙滩椅；推开时椅面（躯干）向远方延展，而收回卷动时，合页（髋关节与脊柱）精准地将结构向中心折叠。深海巨浪中的海带：躯干像是一条深深扎根的海带；脊柱的起伏完全顺应着弹簧拉力的‘洋流’，以一种极其柔韧且充满韧劲的方式完成弧线转换。【空间】无底的深谷：当骨盆向弹簧下方沉降时，想象滑车下方是一个深不见底的虚拟峡谷；让你的尾骨尽量向峡谷深处探索。三维圆柱内壁：感觉你正在一个巨大的透明圆柱体内部运动；你的身体轨迹必须精准地刮过圆柱体的顶端和底端。对角线对拉轴：在滑车推开的瞬间，感受头顶中心与双膝正朝着房间内两条完全平行的对角线延伸。【感觉】温热的蜡块（动觉）：想象你的脊柱是由温热且具有可塑性的蜡块制成的；在下卷过程中，感受每一节椎骨都在由于受热而变得丝滑、柔软。古琴的余震（动觉/听觉）：在动作最高点（桥式位）保持时，感受全身像一根刚刚被拨动的琴弦，维持着一种低频、致密且稳定的内部张力共振。静谧的切水声（听觉）：尝试让滑车在轨道上的滑动变得像刀片切开水面一样无声；用这种极致的静谧感来反馈你对弹簧拉力精准的离心控制。
