CUES 口令
Starting position: Supine, arms by sides, heels or forefeet on foot bar, knees and hips bent to approximately 90 degrees. Breathing: Exhale to push carriage out, extending hips and knees; inhale to bend and return to start. Imagery: Body like a stretched spring.
起始位：仰卧，手放身体两侧，双脚脚跟或前足放在脚踏杆上，膝盖和髋关节弯曲到接近90度。呼吸：吐气将床台往外推，髋膝伸直；吸气弯曲回到起始位。想象提示：身体像一根拉开的弹簧。
IMAGERY 意象
【Direct】During the carriage movement, let the back of your head, the back of your ribs, and the posterior sacrum stay evenly pressed against the mat without any gaps. Keep the center of the knees aligned with the second toe, ensuring the femur glides smoothly within the acetabulum. When pushing the carriage away, distribute pressure evenly across the first, second, and fifth metatarsals to activate the intrinsic foot muscles. 【Indirect】Foot Texture Shift: As the carriage returns, the foot is like a soft bag of bones, spreading to conform to the shape of the footbar; as it pushes away, the foot instantly becomes a rigid pry bar. Precision Saddle: Imagine your ankle joint as a precision rotating saddle (the talus), with the lower leg bones sitting firmly astride it, swinging forward and back. Core Connection: The torso is like a heavy ballast; no matter how the legs move back and forth like pistons, the base remains as steady as a mountain. 【Space】Laser Measures: Imagine your legs are two telescopic laser measures; as the carriage pushes away, the laser beams pierce the opposite wall and extend into infinity. Space Filling: As the carriage returns, use your flexing knees to fill the negative space in front of your body, tracing a full parallel path with the movement. Boundary Challenge: At the end of the push, try to touch the boundaries at both ends of the room with the crown of your head and your toes simultaneously, maximizing your axial length. 【Feeling】Footprint: Imagine the footbar covered in a layer of damp sand; with every push and return, leave a perfect footprint with completely even pressure. Pulley System: During dorsiflexion (heels down), feel your plantar fascia like an auto-tightening pulley system, lightly lifting the arch upward. Hydraulic Quality: Imagine the carriage sliding through thick lubricating oil; every movement is accompanied by a low, steady, and highly controlled 'ssss' sound.
【直接】在滑车移动的过程中，让你的后脑勺、肋骨后方和骶骨后侧始终均匀地贴紧垫子，不产生任何缝隙。保持膝盖中心始终对准第二脚趾的方向，确保大腿骨在髋臼窝内平滑转动。在推开滑车时，将压力均匀分布在第一、第二和第五跖骨上，感受足底肌肉的激活。【间接】足部质感转换：当滑车拉回时，脚掌像一个装满骨头的柔软口袋，顺应脚踏杆的形状铺展开；当滑车推开时，脚掌瞬间变成一根坚固的撬棒。精密马鞍：想象你的踝关节是一个精密的旋转马鞍，小腿骨稳固地跨在马鞍上进行前后的摆动。核心连结：躯干就像是一个沉重的压舱石，无论双腿如何像活塞一样往复运动，基座都始终稳如泰山。【空间】激光测量仪：想象你的双腿是两台可伸缩的激光测量仪，随着滑车的推开，激光束正不断穿透对面的墙壁，向无限远处延伸。空间填充：当滑车返回时，用你屈曲的膝盖去填充身体前方的负空间，让动作的轨迹画出一个饱满的平行路径。边界挑战：在推开滑车至终点时，试着用你的头顶和脚尖同时去触碰房间两端的边界，最大化你的中轴长度。【感觉】足底印记：想象脚踏杆上覆盖着一层湿润的细沙，在每一次推开和拉回时，都要在沙子上留下一个受力完全均匀的完美脚印。滑轮系统：在做足背屈时，感觉你的足底筋膜像一个自动收紧的滑轮系统，将足弓轻盈地向上提拉。液压质感：想象滑车是在浓稠的润滑油中滑动，每一次移动都伴随着一种低沉、平稳且极具控制力的嘶嘶（ssss）声。
TACTILE CUES 触觉提示
Lightly touch outside of knees to guide alignment with second toe; hands on ilia to monitor pelvic stability.
手指轻触膝盖外侧引导对准第2脚趾；手放在髂骨上监控骨盆稳定。
PROGRESSION 进阶
Single leg variations; increase speed; use of jump board; lower foot bar to challenge neutral position.
单脚的变化；增加速度；利用跳板；脚踏杆放低挑战中立位。
REGRESSION 退阶
R- head support elevated, foot bar raised, medium spring tension; simulate movement in non-weight bearing state.
R-头垫高、脚踏杆拉高、【弹簧】重量中等；无负重状态模拟动作。
COMMON ERRORS 常见错误
