CUES 口令
Starting position: Supine, feet on tower bar. Inhale: Prepare; Exhale: Push bar until knees straight; Inhale: Control return. Imagery: Legs opening like a folding fan.

IMAGERY 意象
【Direct】Joint Mechanism: On exhale, feel the femoral heads rotating deeply into the center of the acetabulum, keeping the pelvic weight points motionless as the legs move. Alignment: Maintain the back of the sacrum and posterior thorax evenly molded into the mat throughout, preserving neutral spinal curves. Balanced Loading: Apply symmetric pressure through the balls of the feet into the bar, using spring resistance to monitor bilateral pelvic balance. 【Indirect】Architect's Square: Imagine your body as a large architect's square; the torso is the stable base, and the legs are drawing arms precisely measuring the vertical dimension. Water Tray: View the tower bar as a tray holding a full glass of water; use core stability and steady pushing to ensure the surface remains ripple-free. Calibrated Compass: Imagine your body as a calibrating compass; each leg movement projects infinite energy along the north-south axis. 【Space】Transparent Glass Tracks: Imagine the bar sliding along two transparent glass tracks reaching toward the ceiling, with your leg path fitting perfectly within this plane. Filling the Frame Void: On the return, imagine your breath filling all the empty space within the Cadillac frame, making your body 3D and stable. Supporting the Ceiling Air: Feel energy spilling from your toes to touch and prop up the air layers at the top of the room, maximizing your vertical lifeline. 【Feeling】A Firm Handshake (Resistance/Tactile): Feel the spring tension as a steady, warm handshake; 'borrow' strength from this force to find joint congruency. Still Water Viscosity (Texture): Imagine the air above the bar as buoyant still water; each push and return requires smoothing through water molecules for a fluid quality. Constant 'Hum' Resonance (Auditory): Capture a steady 'humming' resonance in your mind, matching your leg speed to this mental frequency to eliminate any jerks.
【直接】关节机制：呼气向上推时，感受股骨头在髋臼窝中心进行深层旋入，在大腿移动时保持骨盆受力点纹丝不动。排列要求：伸展全程保持骶骨后侧与后胸廓均匀模刻在垫子上，维持脊柱自然中立。受力均衡：通过双脚脚球向塔杆施加绝对对称压力，利用弹簧阻力实时监测双侧骨盆平衡。【间接】精密建筑方尺：想象身体是一把巨大的建筑方尺，躯干是稳固基座，双腿是正在精确测量垂直维度的绘图臂。盛水托盘：视塔杆为一个承载盛满水托盘的平面，通过核心稳定与匀速推动，确保水面不产生一丝涟漪。精准校准的指南针：想象身体是一部正在校准的指南针，双腿起落均沿着南北中轴线进行无限能量投射。【空间】透明玻璃轨道：想象塔杆正沿着延伸至天花板深处的两条透明玻璃轨道滑动，双腿轨迹严丝合缝地贴合该平面。填满框架虚空：吸气回程时，想象呼吸正填满秋千床框架内的所有虚空，使身体在三维空间中更立体稳固。支撑顶部空气层：感受能量从足尖溢出，去触碰并支撑起房间顶部的空气层，在垂直维度拉开最大生命线。【感觉】温暖的握手（阻力/触觉）：感受弹簧张力如同一次稳固而温暖的握手，向这股力量“借力”找回关节间的相合对位。静水的粘性（质感）：想象塔杆上方空气变得如同有浮力的静水，推起和收回需平稳克服水分子粘性，维持动作丝滑。恒定的“嗡嗡”共振（听觉）：内心捕捉节奏恒定的共振声，将下肢速度与心理频率完美匹配，消除动作突变。
TACTILE CUES 触觉提示
Hands on knees to guide path; lightly touch pelvis to ensure stability.
手在膝上引导轨迹；轻触骨盆确保稳定。
PROGRESSION 进阶
P- increase resistance; add upper body curl.
P-增加阻力；增加上肢卷起动作。
REGRESSION 退阶
R- single leg push; reduce spring tension.
R-单脚推；降低弹簧阻力。
COMMON ERRORS 常见错误
Poor lower limb alignment; not maintaining spinal alignment; movement lacks control.
下肢排列不良；无维持脊椎排列；动作松垮。
PRECAUTIONS 注意事项
Contraindications: THR(P), acute disc conditions. Adjust foot position if painful.
禁忌：THR(P)、急性盘症。痛时调脚位。
