CUES 口令
Starting positions: 1. Elephant - stand on carriage, hands on foot bar, body in inverted V. 2. Long Stretch - push-up position, heels against shoulder rests. 3. Jackrabbit - push-up position, knees bent toward chest. Movements: Elephant - exhale push carriage away, inhale return. Long Stretch - inhale extend shoulders to push carriage away, exhale return. Imagery: Body like a rigid steel plate moving horizontally in space.
起始位：1. Elephant-站在滑板上，手扶脚踏杆，身体呈倒 V 型。2. Long Stretch-俯卧撑姿势，脚跟抵住肩靠。3. Jackrabbit-俯卧撑姿势，膝盖弯曲靠近胸口。动作：Elephant-吐气推开滑板，吸气拉回。Long Stretch-吸气肩关节伸展将床推开，吐气拉回。想象提示：身体像一块坚硬的钢板，在空间中水平移动。
IMAGERY 意象
【Direct】While the carriage moves back, maintain a constant vertical distance between the lower ribs and the ASIS. Keep the opposition between the crown of the head and the sit bones toward opposite poles of the room. Focus on keeping the medial borders of the scapulae flat against the posterior ribs, resisting spring tension to prevent shrugging. 【Indirect】Precision Compass: Imagine your torso as the fixed needle of a precision compass; as the carriage moves, the shoulders remain still as the center while the body swings accurately like a scale line. Rising Tide Buoyancy: Imagine an invisible tide slowly rising beneath your pelvis, weightlessly lifting your sacrum and distributing weight evenly to the feet. Cocked Crossbow: Imagine the body as a fully drawn crossbow frame; though the carriage is in motion, the trunk structure remains extremely calm and solid. 【Space】Parallel Glass Gallery: Feel as if you are between two narrow, parallel glass walls; during the push and pull, the body never produces any lateral sway. Height Scanner: Imagine your tailbone touching an infrared height scanner; throughout the trajectory, ensure the tailbone's height in space remains absolutely constant. Energy Cone: Visualize a transparent energy cone narrowing from the shoulders to the heels; as the legs extend, pierce the tip of the cone deep into the void behind. 【Feeling】Stretching Warm Taffy: Feel the spring resistance like pulling a thick, warm clump of taffy; the movement carries a silky, steady, and highly eccentric viscous control. Air Compression Pad: Imagine a very thin air compression pad between your palms and the footbar; press down on this invisible cushion to gain an internal-to-external upward lift of the ribcage. Resonant String: Listen quietly to the sound of the carriage rollers, attempting to perfectly synchronize your movement rhythm with the slight vibration of the springs until the sound dissolves into your breath.
【直接】在滑车后移时，维持下端肋骨与骨盆髂前上棘之间的垂直距离恒定。保持头顶顶点与坐骨往房间相反的两个极点对拉。专注于让肩胛骨内侧缘平整地贴合在肋骨后侧，对抗弹簧张力，防止肩膀向耳侧上提。【间接】精密指南针：想象你的躯干是精密指南针的固定指针；滑车移动时，肩膀作为圆心纹丝不动，身体则像刻度线一样精准摆动。涨潮浮力：想象骨盆下方有一股隐形的潮汐正缓缓升起，这股浮力轻盈地托举着你的骶骨。蓄势的弩机：将身体想象成一个拉满弦的弩机架，虽然滑车在动态位移，但躯干结构始终保持着极致的冷静与坚固。【空间】平行玻璃廊：感觉你正置身于两片极窄且平行的玻璃墙之间；在滑车推拉过程中，身体绝不产生任何侧向摆动。扫描高度仪：想象你的尾骨正在触碰一台红外线高度扫描仪，在整个动作轨迹中，确保尾骨在空间中的高度保持绝对恒定。能量锥体：视觉化一个从双肩向脚跟收窄的透明能量锥体；当腿部伸展时，将锥体的尖端深深刺入后方的虚空。【感觉】拉伸温热糖稀：感受弹簧的阻力如同在拉动一团浓稠、温热的糖稀，动作带有一种丝滑、沉稳且极具离心控制力的粘滞感。空气压缩垫：想象手掌与脚踏杆之间隔着一层极薄的空气压缩垫；向下推压这个隐形气垫，获得胸廓由内向外的上提力量。共鸣丝弦：静静聆听滑车滚轮的声音，尝试让动作节奏与弹簧轻微的震动声完美同步，直到声音消失在呼吸中。
