CUES 口令
Starting position: Sit on edge of chair, sit bones near front edge, back neutral. Balls of feet on pedal, heels together or parallel. Breathing: Inhale prepare; Exhale press pedals toward floor; Inhale control return, maintaining spinal elongation. Imagery: Feet moving like precise vertical pistons.
【起始位】坐于椅子边缘，坐骨靠近前缘，背部中立位。脚前掌置于踏板，脚跟并拢或平行。【呼吸】吸气预备；吐气时将踏板向地板方向压；吸气控制回弹，保持脊柱延伸。【想象】想象双脚像活塞一样精准垂直运动。
IMAGERY 意象
【Direct】Maintain precise vertical alignment of the ear canal, acromion, and greater trochanter, ensuring the trunk does not tilt forward or backward with pedal pressure. Focus on the femoral head rolling deep within the acetabulum; as you press the pedal, maintain spinal neutrality through the connection between the pubis and lower ribs. Keep the center of the second toe and the knee cap rising and falling within the same sagittal plane. 【Indirect】Stable Hydraulic Lift: Imagine your torso as a steady vertical lifting platform, with the base (sit bones) firmly anchored to the chair seat. Cockpit Simulation (Eccentric Control): Imagine the pedal as a sensitive speed controller; pressing down is a smooth acceleration, while releasing requires precise 'cadence braking.' Folding Carpentry Ruler: The body is like an unfolded folding ruler; the hip joint is the sole load-bearing pivot, with core power driving the opening and closing. 【Space】Vertical Elevator Shaft: Feel your back flush against a cool, vertical elevator shaft wall; during pedaling, the back of the head, thoracic spine, and sacrum must not leave the wall. Ceiling Upward Pressure: Imagine a delicate graduated cylinder full of water balanced on your head; as you press the pedal, use the counter-pressure to reach for the cylinder. Narrow Slot Gliding: Imagine your knees sliding up and down within two extremely narrow transparent glass slots; the trajectory must be perfectly vertical. 【Feeling】Silent Muting (Auditory): Listen quietly to the sound of the springs; try to let the pedal's ascent dissolve into your breathing rhythm, making the contact with the frame silent. Dense Amber Resistance (Kinesthetic): Feel the air becoming like warm, viscous amber liquid; both pressing and returning require a uniform, deep force to 'slice' through this damping. Foot Suction Cups (Tactile): Imagine the soles of your feet as two powerful suction cups firmly attached to the pedal; this grounded stability supports the upward expansion of your ribcage.
【直接】保持耳穴、肩峰与股骨大转子在垂直线上精准对齐，确保躯干不随踏板的下压而产生前倾或后仰。专注于股骨头（大腿骨顶端）在髋臼内深处向后滚动，在压下踏板时，通过耻骨与下端肋骨的连结来维持脊柱中立。保持第二脚趾中心与膝盖中心在同一个矢状面内升降。【间接】平稳的液压升降台：想象你的躯干是一座稳固的垂直升降台，底座（坐骨）紧紧锚定在椅面上。模拟驾驶舱（离心控制）：将踏板想象成灵敏的车速控制器；压下时如同平稳提速，而放回时则要精准“点刹”。折叠木工尺：身体如同一把展开的折叠木工尺，髋关节是那个唯一的受力转轴，核心动力驱动着尺身的开合。【空间】垂直电梯井：感觉你的背部紧贴着一面冰凉的垂直电梯井壁；在双腿踩踏的过程中，后脑勺、胸椎后侧和骶骨绝不能离开井壁半分。天花板的顶力：想象头顶正顶着一个装满水的精细量筒，在压下踏板的瞬间，利用下压的反作用力向上去够那个量筒。窄缝滑行：想象你的膝盖正在两条极窄的透明玻璃槽内上下滑动，动作轨迹必须精确垂直。【感觉】静谧的消音（听觉）：静静听听弹簧拉伸的声音，尝试让踏板回升的过程完全消融在你的呼吸律动中。稠密琥珀的阻力（动觉）：感受空气变得像温热且粘稠的琥珀液体；压下和收回的过程都需要你施加均匀且深沉的力量。足底的吸盘（触觉）：想象你的双脚脚掌是两个强力吸盘，紧紧吸附在踏板表面；这种下扎的稳固感正逐节向上支撑起你胸廓的拓宽。
TACTILE CUES 触觉提示
Instructor places fingers on client's ASIS to ensure pelvic stability; lightly touch knees to guide alignment with second toes.
导师手指置于练习者髂前上棘（ASIS）确保盆底稳定；轻触膝盖引导对准第二脚趾。
PROGRESSION 进阶
P- sit on a cushion to challenge proprioception and balance.
P-坐在软垫上以挑战本体感觉与平衡。
REGRESSION 退阶
R- place a small box under pedals to limit range of motion.
R-踏板下方放小盒子挡住，以减少活动范围。
COMMON ERRORS 常见错误
Anterior or posterior pelvic tilt; heels lifting or pressing too hard; knees not tracking over second toes; body leaning forward or back; feet overly tense or limp.
