CUES 口令
Starting position: Supine, feet in loops, legs at 45-degree angle. Breathing: Inhale to flex hips, moving feet toward ceiling; exhale to push toward foot bar. Imagery: Toes like paintbrushes drawing arcs on ceiling.
起始位：仰卧，脚放在套环中，双腿在45度角位置。呼吸：吸气弯曲髋关节将脚往天花板移动；吐气推向脚踏杆。想象提示：脚尖像是在天花板上画弧线的画笔。
IMAGERY 意象
【Direct】As the legs move, maintain even pressure of the back of the head, posterior ribcage, and sacrum against the mat without creating gaps as the legs rise or fall. When the legs lift toward the ceiling, use a deep inhalation to counteract the spine's tendency to flex, thus maintaining a neutral position. Focus on the deep rotation of the femoral head within the acetabulum, ensuring the pelvis does not rock side-to-side during leg abduction. 【Indirect】Anchor and Oars: Imagine your torso is a heavy anchor sunken to the seabed, while your legs are long, light oars tracing smooth and symmetrical ripples on the open water. Construction Crane: The torso is like a stable crane base, and the legs are the telescopic jib, driven by a central power source to draw precise circles in the air. Elastic Ropes: Imagine the springs are an extension of your hamstring fascia; feel as if you have long, elastic legs like Spider-Man. 【Space】Reaching for the Horizon: Imagine your toes trying to reach the farthest corner at the other end of the room; as the legs press down, stretch the distance between your ankles and pelvis infinitely. Invisible Dome: Trace a giant translucent dome in the air with your toes, ensuring the movement fills every inch of negative space above your body. Laser Measures: Feel vertical laser beams emitting from the soles of your feet; as you circle, the beams must precisely sweep across the edges of the ceiling without leaving any blind spots. 【Feeling】Electrostatic Field: Feel a strong electrostatic attraction between your inner thighs and abdominals, naturally converging as the legs close and maintaining tension as they open. Smooth Orbit: Imagine your legs moving through viscous liquid air; every movement carries a uniform, steady resistance without sudden acceleration or deceleration. Machine's Breath: Listen quietly to the sound of the carriage gliding; let the smooth, silent motion be the feedback for your core control, feeling the ease and precision in the movement.
【直接】在双腿移动时，保持后脑勺、胸廓后侧和骶骨始终与垫子维持均等的压力，不随腿部起落而产生缝隙。当双腿向天花板方向抬起时，通过深长吸气来对抗脊柱想要产生屈曲的趋势，以此维持中立位。专注于股骨头在髋臼窝内的深层转动，确保骨盆不因腿部外展而左右晃动。【间接】锚点与桨：想象你的躯干是一个沉入海底的重型锚碇，而双腿则是长而轻盈的船桨，在开阔的水面上划出平稳且对称的波纹。建筑塔吊：躯干就像是稳固的塔吊底座，而双腿是那根可伸缩的吊臂，由中心动力源驱动，在空中精准地画圆。弹性绳索：想象弹簧是你大腿后侧筋膜的延伸，感觉自己拥有了一双像蜘蛛侠一样充满弹性的长腿。【空间】触碰天际：想象你的脚尖正在试图够到房间另一端的最远角，随着腿部下压，让脚踝与骨盆之间的距离被拉到无限长。隐形穹顶：用你的足尖在空中描绘一个巨大的半透明穹顶，确保动作填满了身体上方的每一寸负空间。激光测量仪：感觉脚底射出两道垂直的激光束，在画圆时，激光束必须精准地扫过天花板的边缘，不留死角。【感觉】静电场：感受大腿内侧和腹肌之间存在一种强力的静电吸引力，这种吸引力在腿部合并时自然汇聚，在打开时维持着张力。平滑轨道：想象你的腿正在粘稠的液态空气中穿行，每一次动作都带有均匀、沉稳的阻力，没有突发的加速或减速。机器的呼吸：静静聆听滑车滑动的声音；让顺滑无声的滑行感成为你核心控制力的反馈，感受动作中的从容与精准。
TACTILE CUES 触觉提示
Lightly touch front of ribs to encourage sinking; fingers touch soles of feet to guide lengthening away.
手轻触肋骨前端引导下沉；手指触碰足底引导向远处拉长。
PROGRESSION 进阶
P- decrease or increase spring challenge; P- increase range of motion; P- add challenging sequences (e.g., Peter Pan).
P-减少或增加弹簧挑战；P-增加活动范围；P-加上挑战性动作编排（如Peter Pan）。
REGRESSION 退阶
R- increase spring tension for assistance; R- limit range of motion.
