CUES 口令
Starting position: Quadruped, head toward foot bar, hands on frame (shoulders aligned over hands), knees and hips bent ~90°, feet between or against shoulder rests. Breathing/movement options: 1. Hip flexion/extension: Exhale push carriage back, inhale return. 2. Shoulder flexion/extension: Exhale push frame with hands, carriage back, inhale return. 3. Integration: Exhale extend opposite arm and leg simultaneously. Imagery: Body like a stable four-legged table, top always level.
起始位：四足跪姿，头朝脚踏杆方向，手在框架上（肩膀大对齐手的位置），膝与髋屈曲约90度，脚放在肩靠中间或抵住肩靠。呼吸/动作建议：1. 髋屈/伸：吐气推滑板往后，吸气拉回。2. 肩屈/伸：吐气手推框架滑板往后，吸气拉回。3. 整合：吐气对侧手脚同时伸展。想象提示：身体像一张稳固的四角方桌，桌面始终保持水平。
IMAGERY 意象
【Direct】Keep the back of the head, thoracic spine, and posterior pelvis on the same horizontal plane, as if the back is pressed against a straight pole. When lifting the arm, focus on the humeral head rolling down within the joint socket to avoid scapular elevation or winging. When extending contralateral limbs, guide the fingertips and toes to pull toward opposite far points while maintaining level iliac crests through abdominal indrawing. 【Indirect】Stable Suspension Bridge: The torso is like a sturdy suspension bridge deck, with the core as the main cable supporting gravity, ensuring the deck remains motionless as the limb 'piers' move. Precision Piston Box: Imagine your pelvis as a sealed piston box, with the femur moving back and forth smoothly inside without causing any angular shift or tremor in the box. Hovering Level: The body is like a laser level at work; no matter how the limbs extend, the green horizontal beam stays precisely aimed at a fixed height on the front wall. 【Space】Passing Through a Narrow Alley: Feel as if you are kneeling on all fours in the center of an extremely narrow, transparent corridor; your sides must never touch the glass walls while moving your limbs. Extended Energy Axis: Imagine the spine as a long energy axis piercing through the room, with the crown beam piercing the void ahead and the tailbone extending infinitely toward the horizon behind. Filling Air Molds: Use your lower abdomen and back to fill the invisible molds around your body, ensuring the trunk fills every inch of space during carriage movement without collapsing. 【Feeling】Maglev Thrust: Feel an upward magnetic levitation thrust beneath your palms and knees, gently lifting your ribcage and pelvis away from the carriage to offset the feeling of gravity. Dense Medium: Imagine moving through warm, thick liquid air; every limb extension carries a steady, uniform, and dampened quality, eliminating any sudden acceleration. Built-in Resonator: While maintaining stability, listen internally to a low 'mmm' resonance, feeling this frequency spread from the core to the limbs, sustaining a high sense of full-body synergy.
【直接】保持后脑勺、胸椎后侧和骨盆后侧在同一水平面上，如同背部贴合着一根笔直的棍子。在抬起手臂时，专注于让肱骨头在关节窝内向下滚动，避免肩胛骨产生上提或翼状代偿。伸展对侧肢体时，引导指尖与脚尖向两端最远点对拉，同时通过腹壁内收维持两侧髂骨的高度一致。【间接】平稳的悬索桥：躯干如同一座坚固的悬索桥桥面，核心是那根支撑重力的主钢缆，确保在四肢这些桥墩移动时，桥面始终纹丝不动。精密活塞箱：想象你的骨盆是一个密闭的活塞箱，大腿骨在内部极其顺滑地往复运动，不引起箱体任何角度的偏移或震颤。悬浮的水平仪：身体像一根正在工作的激光水平仪，无论四肢如何伸展，那道绿色的水平光束始终精准地射向正前方墙壁的固定高度。【空间】穿过窄巷：感觉你正四足跪在一段极窄且透明的走廊中心，在移动肢体时，身体两侧绝不触碰两旁的玻璃墙。延伸的能量轴：想象脊柱是一根穿透房间的能量长轴，头顶的光束刺破前方的虚空，尾骨则向后方的地平线无限延伸。填充空气模具：用你的下腹部和背部去向外填满身体周围的隐形模具，确保躯干在滑车移动时填满每一寸空间，不产生任何塌陷。【感觉】磁悬浮推力：感受手掌与膝盖下方存在一种向上的磁悬浮推力，这种力量轻柔地将你的胸廓和骨盆托离滑车，抵消了重力感。稠密介质：想象你在温暖且稠密的液态空气中移动，每一次肢体的伸展都带有沉稳、均匀且带阻尼的质感。内建共鸣器：在保持稳定时，内心听听那低沉的嗡（mmm）共振声，感受这种频率从核心扩散至四肢，维持着全身高度的协同感。
TACTILE CUES 触觉提示
Hand on sacrum to guide pelvic level; lightly touch supporting shoulder to cue stability.
手放在骶骨处引导盆底水平；轻触支撑侧肩膀引导稳定。
PROGRESSION 进阶
P- lighten springs to increase core challenge; P- increase range of motion; P- increase spring tension to challenge counterbalance or shoulders.
P-将弹簧变轻以增加核心挑战；P-增加活动范围；P-加重弹簧增加对抵消或肩部的挑战。
REGRESSION 退阶
R- reduce range of motion; R- perform single-limb movements only.
R-减小活动范围；R-仅进行单肢动作。
COMMON ERRORS 常见错误
