CUES 口令
Starting positions: Facing In: Stand on pedals on toes, facing chair, hold handles, elbows straight but not locked. Facing Out: Stand on pedals facing away from chair, hold handles. Breathing: Facing In: Inhale extend trunk, widen scapulae; exhale bend elbows, avoiding humeral head protraction, press body up/down. Facing Out: Inhale extend trunk; exhale bend elbows, press body up. Imagery: Body like a precise support moving on parallel bars.
【起始位】Facing In：垫脚尖站在踏板上，面向椅子，手握手把，肘关节伸直但不锁死。Facing Out：背向椅子站在踏板上，手握手把。 【呼吸模式】Facing In：吸气躯干延伸，肩胛放宽；吐气时手肘弯曲，同时要避免肩骨头往前面顶，将身体撑起/下降练习。Facing Out：吸气躯干延伸，吐气时手肘弯曲，将身体往上顶。 【想象】身体像是在双杠上移动的精密支架。
IMAGERY 意象
【Direct】Exhale to extend arms and push the pelvis off the chair until elbows are fully extended but not locked. During the ascent, feel the scapulae sliding smoothly toward the waist, lengthening the neck. Maintain vertical alignment of the ears, shoulders, and hips during the descent. 【Indirect】Steady Elevator: Imagine your body as a steady elevator, with your arms as the hydraulic pillars driving a smooth ascent. Solid Steel Beams: View your arms as two solid steel beams, maintaining firm symmetry regardless of body movement. Ancient Heavy Bell: Imagine your torso as a heavy bell being lifted vertically from the ground by its support frame (your arms). 【Space】Touching the Highest Point: As you push up, imagine your shoulders reaching for the room's highest point, extending infinitely in the vertical dimension. Pushing Air Aside: During the descent, feel your elbows pushing the air out to the sides to maintain maximum width in the chest and back. Void Beneath the Feet: Imagine the space between your feet and the pedal collapsing into a deep void as you rise, creating a sense of immense emptiness. 【Feeling】Pressure Penetration (Tactile): Feel the handles like cold iron pillars, with force penetrating evenly from the palms through to the chair frame. Upward Breeze (Proprioception): During the ascent, feel the spring assistance making you light as a feather, as if an upward breeze is hoisting your hips. Placing a Glass Vase (Kinesthetic): During the descent, imagine slowly lowering a fragile glass vase into a narrow box, requiring extreme precision in every millimeter of movement.
【直接】呼气时，通过伸直双臂将骨盆推离椅子表面，直到手肘完全伸展但不锁死。在上升过程中，感受肩胛骨向腰部方向顺滑下沉，增加颈部的长度。下降时，保持耳垂、肩膀与髋部处于一条垂直线上。【间接】稳固的电梯：想象你的身体是一部稳固的电梯，双臂是驱动电梯平稳上升的液压柱。坚实的钢梁：视双臂为两根坚实的钢梁，无论身体如何移动，支柱始终保持稳固对称。沉重的古钟：想象你的躯干是一口沉重的古钟，正在被支架（手臂）从地面垂直拎起。【空间】触碰最高点：向上推时，想象你的肩膀正试图触碰房间的最高点，在垂直维度上无限延伸。推开空气：在下降时，感受双肘向两侧推开空气，以维持胸廓和背部的最大宽度。脚下的虚空：想象当你升起时，脚底与踏板之间的空间正在向深处塌陷，创造出巨大的虚空感。【感觉】压力的穿透（触觉）：感受把手如同冰冷的铁柱，下压时力量均匀地从掌心穿透至椅子框架。向上的微风（本体觉）：在上升时，感受弹簧的辅助力让你轻如羽毛，仿佛一阵向上的微风正托举着你的髋部。放置玻璃花瓶（动觉）：下降时，想象你正将一个易碎的玻璃花瓶缓慢放进窄箱子，要求每一毫米的移动都极其精准。
TACTILE CUES 触觉提示
Instructor checks handle width (may be too wide for some); ensure adequate ceiling height for standing.
导师确认手把位置对一些人来说太宽；确保天花板高度足够（针对站立位）。
PROGRESSION 进阶
P- add extension or flexion to increase stretch; P- keep elbows straight, perform scapular elevation/depression.
P-加上在后仰或前弯姿势，拉伸身体更多；P-可以对手肘保持伸直，做肩胛上提与下沉练习。
REGRESSION 退阶
To regress, start with Forward Lunge standing on chair, hands on handles, slowly lower pedals.
若要降低挑战，可先做Forward Lunge站在椅子上，双手在手把上，慢慢往下载踏板。
COMMON ERRORS 常见错误
Lack of axial elongation, chin poking, trunk flexion; unwanted scapular elevation or excessive protraction/retraction; elbow locking; hips shifting forward; knees bending.
没有中轴延伸，下巴往前顶，躯干屈曲；不该有的肩胛上提或过度前引/后收；肘关节锁死；髋骨前移；膝盖弯曲。
PRECAUTIONS 注意事项
Shoulder issues (e.g., frozen shoulder, rotator cuff injury).
肩部问题（如肩周炎、肩袖损伤等）。
