SETUP 设置
Springs: 1/2-1 spring (usually 1 red or blue); long box in place; foot bar down.
【弹簧】1/2-1根弹簧（通常1红或1蓝）；长箱放好位置；踏杆放下。
CUES 口令
【Starting Position】Lie supine on the box with shoulders near the edge. Hold the loops with palms facing out and elbows wide. Knuckles touching above the sternum. Knees and hips flexed, upper body curled up into a Chest Lift position. 【Breathing】Inhale: Extend arms and legs toward the ceiling, keeping the carriage still. Exhale: Circle arms and legs outward and down toward the footbar, ending in the Hundred position. Increase thoracic flexion slightly and pause to exhale completely. Inhale: Challenge the abdominal contraction. Exhale: Bend arms and legs to return to the starting position, maintaining the curl. Repeat 4-6 times. Can also be practiced in reverse order. 【Variations】Roll the head down at the end of each repetition. Perform on the carriage instead of the box, with the torso either curled or flat.
【起始位】仰卧在箱子上，肩膀靠近箱子边缘。手抓套环，手心向外，手肘朝外。指关节相靠，在胸骨上方位置。膝盖和髋屈曲，上半身卷起到Chest Lift位置。【呼吸】吸气：手臂和腿朝天花板方向伸直，滑床保持不动。吐气：手臂和脚往外绕圈，然后往脚踏杆方向，结束于Hundred的位置，胸椎屈曲再多一点，停一下，以便完全吐气。吸气：挑战腹部收缩。吐气：手臂和腿弯曲回到起始位置。身体仍然保持卷起姿势。重复练习4-6次。可以动作顺序相反练习。【变化】每次动作结束时，头部往下卷。不仰躺在箱子上而是在滑床上，身体可以卷起或不卷起。【预热】Supine Arm Series(Circle），Hundred, Supine Abdominal Series:Coordination
IMAGERY 意象
【Direct】Maintain the upper body in a Chest Lift position, letting fingertips and toes point precisely toward the ceiling to form four parallel vertical lines. During circles, keep the back of the sacrum firmly pressed against the long box without anterior pelvic tilt. On inhalation, sweep arms through the sides, ensuring the humeral head glides within the joint socket.【Indirect】Compasses: Imagine your limbs as four precision compasses drawing concentric circles centered at the joints. Compass Needle: The torso is a stable base while the limbs are sensitive magnetic needles; the base remains pointing to the center. Folding Fan: Imagine your body as an opening folding fan, with arms and legs fanning out with equal tension.【Space】Transparent Cylinder: Feel as if you are inside a giant transparent cylinder; hands and feet glide against the inner walls, extending infinitely. Inflatable Sphere: Imagine an invisible transparent ball beneath you; limbs rotate around this sphere without crushing it. Picture Frame: Reach with your hands and feet toward the invisible boundaries around the long box, filling the entire spatial dimension.; 【Feeling】Magnet Effect: Feel a strong magnetic attraction between your lower back and the long box; the torso remains motionless. Slicing the Air: As arms circle quickly, listen for the 'shoo' sound, feeling the crispness and speed. Warm Wax: Imagine your limbs stirring through warm, molten wax, experiencing a uniform, steady, and silky resistance.
【直接】维持上半身卷起至肋骨支撑位（Chest Lift），让指尖与脚尖精准地指向天花板，形成四条平行的垂直线。在画圆过程中，保持骶骨后侧稳稳压在长箱上，不随腿部下落而产生骨盆前倾。吸气时，让双臂从身体两侧划过，确保肱骨头在关节窝内滑动，不产生耸肩代偿。【间接】圆规：想象你的四肢是四个精密的圆规，以髋、肩关节为圆心，在空中划出弧度完全一致的同心圆。指南针：躯干像是一个稳固的基座，而四肢则是四根灵敏的指南针磁针，无论如何转动，基座都始终保持指向中心不动。折扇：想象你的身体像一把正在打开的折扇，双臂与双腿同时向外扇形展开，维持扇骨之间的均等张力。【空间】透明圆柱：感觉你正身处一个巨大的透明圆柱体内，在画圆时，手脚始终紧贴着圆柱体的内壁滑动，向四周无限延伸。充气球体：想象身体下方有一个看不见的透明大球，你的手和脚正环绕这个球体进行旋转，既不挤压球体，也不远离它。画框：用你的手脚去触碰长箱四周不可见的边界，让动作尽可能占满整个空间的维度。【感觉】磁铁效应（触觉）：感觉你的下背部和长箱之间有强力磁铁互相吸引，即便四肢向远处延伸，躯干依然纹丝不动。划破空气（听觉）：在手臂快速绕圆并击打滑车时，听听空气中发出的‘呼（shoo）’的一声，感受动作的利落与速度感。温热的蜡（动觉）：想象四肢在温热的融化蜡液中搅动，每一步动作都带有均匀、沉稳且丝滑的阻力感。
TACTILE CUES 触觉提示
Hands supporting inferior angle of scapulae to maintain curl height; lightly touch abdominals to cue deep contraction on exhale; guide leg circle path.
手托住学员肩胛下角协助维持卷起高度；轻触腹部提示呼气时腹部深度收缩；指引双腿绕圈的轨迹。
PROGRESSION 进阶
Increase the flow of the movement or try more challenging Long Box series variations, while maintaining high-quality movement execution.
在维持高标准动作质量的前提下，增加动作的连贯性或尝试更具挑战性的长箱系列变式
REGRESSION 退阶
Reduce the range of motion of the limbs to ensure the core remains stable and the lumbar spine does not compensate. Drop long box, support for head
减小肢体活动的范围，以确保核心能够维持稳定且腰椎不产生代偿。去掉long box，头部有支撑
COMMON ERRORS 常见错误
Inability to maintain chest lift; inability to keep abdominals engaged on inhale (abdominal bulge on inhale); excessive cervical flexion/extension; lumbar extension; shoulder elevation.
身体无法保持在Chest Lift位置；吸气时无法保持腹肌收缩（吸气时腹部隆起）；颈椎过度后仰前弯；腰椎后仰伸展；肩带上提。
PRECAUTIONS 注意事项
Disc herniation, spinal stenosis, severe osteoporosis, acute cervical pain.
椎间盘突出、椎间管狭窄、严重的骨质疏松、急性颈椎疼痛。
