CUES 口令
Starting positions: Side Lunge: Stand on chair, turn sideways, outer foot on pedal. Sideward Stepdown: Stand on chair, one leg bends into squat. Breathing: Side Lunge: Inhale bend top leg, press pedal down; exhale press into pedal, rise vertically. Sideward Stepdown: Inhale down, exhale up. Imagery: Body moving vertically in a narrow lateral corridor.
【起始位】Side Lunge：站在椅子上，转动身子向侧边准备，外侧脚踩在踏板。Sideward Stepdown：站在椅面，一腿弯曲下蹲。【呼吸模式】Side Lunge：吸气上面腿弯曲，下压踏板；吐气脚压向踏板，身体垂直上升。Sideward Stepdown：吸气向下，吐气向上。【想象】身体像在狭窄的侧向通道中垂直升降。
IMAGERY 意象
【Direct】Inhale to bend the top knee, pressing the pedal toward the floor while maintaining a neutral pelvis. Exhale to ground the supporting foot and rise vertically. Ensure the working knee aligns with the second toe and maintain axial elongation through the crown. 【Indirect】Lateral Marriage Proposal: Imagine you are performing an elegant lateral marriage proposal; this imagery instantly restores vertical spinal alignment and prevents leaning forward. Helium Balloon Traction: Imagine a large helium balloon attached to your crown, lightly lifting your body vertically and reducing joint loading. Cork Floating: The pedal is like a cork rising steadily from underwater; use core strength to 'hold down' the spring's surge and maintain fluidity. 【Space】Filling Lateral Space: In Side Lunge, imagine your body expanding infinitely to the left and right, attempting to fill the entire width of the room. Visual Sight: Fix your gaze on a distant point, using this visual anchor to stabilize your center of gravity and eliminate wobbling. Entering Deep Space: As you press down, imagine entering a vast and deep negative space, using extension to create room within the joints. 【Feeling】Thick Syrup Damping (Kinesthetic): Imagine moving the pedal through thick syrup, requiring a deep, uniform force to 'slice' through resistance without using momentum. Heel Peeling (Tactile): As you rise, feel your heel 'peeling' away from the floor like Velcro, channeling force precisely upward. Cloud-like Floating (Proprioception): As the pedal returns, feel a sense of buoyancy in the pelvis, as if the spring is gently hoisting you upward.
【直接】吸气时上方膝盖弯曲，在保持骨盆中立的同时将踏板压向地板。吐气时支撑脚踩稳，躯干垂直向上升起。确保弯曲腿的膝盖始终对准第二脚趾，并保持头顶向天花板延伸。【间接】侧向的求婚：想象你正在进行一场优雅的侧向求婚，这个意象能瞬间帮你找回脊柱的垂直排列，防止身体前倾。氦气球牵引：想象头顶系着一个巨大的氦气球，正轻盈地带着你的身体垂直上升，减轻关节承重。软木塞平稳浮起：踏板如同从水底平稳浮起的软木塞，用核心力量“按住”弹簧的冲力，维持动作流畅。【空间】横向填满空间：在做侧箭步时，想象你的身体正在向左右两边无限扩张，试图填满整个房间的宽度。视觉准星：双眼平视远处的一个固定点，利用视觉焦点来锚定身体重心，消除摇摆。进入深邃空间：在屈膝下压时，想象你正进入一个宽阔而深邃的负空间，通过肢体延伸增加关节间的间隙。【感觉】厚糖浆的阻尼（动觉）：想象你在浓稠的糖浆中移动踏板，需要用深沉、均匀的力量去“划开”阻力，杜绝爆发力。脚跟的剥离感（触觉）：在身体上升时，感觉你的脚跟正从地板上像撕开魔术贴一样逐层“剥离”，将力量精准向上传递。云端的悬浮感（本体觉）：在踏板回弹时，感受骨盆有一种向上漂浮的轻盈感，仿佛弹簧的辅助力正温柔地托举着你。
TACTILE CUES 触觉提示
Instructor holds client's pelvis to prevent lateral tilt; lightly touch stance knee to ensure alignment with toes.
导师手扶练习者骨盆确保不发生侧倾；轻触支撑腿膝盖确保对准脚尖。
PROGRESSION 进阶
P- release handle.
P-不扶手把杆。
REGRESSION 退阶
R- place small box under pedals to reduce hip/knee flexion angle and limit range.
R-在踏板下放小盒子，以减少髋与膝盖弯曲角度及限制关节活动范围。
COMMON ERRORS 常见错误
Hip rotation or hiking; foot pronation, knee collapsing inward past midline; weight not shifting to stance foot; overusing quadriceps without hip extensor engagement.
髋部旋转或提起；脚旋前，膝盖往内超过中线；重心没有往站立腿的脚移动；过度使用股四头肌而没有髋伸肌的力量。
PRECAUTIONS 注意事项
Acute knee injury, severe balance impairment.
急性膝关节损伤、严重平衡障碍。
