CUES 口令
Starting position: Sit on floor in front of pedals, feet on chair edge, hands on pedals. Start with slight posterior pelvic tilt, balance just behind sit bones. Breathing: Inhale lengthen neck, depress scapulae; exhale press pedals down, body curls forward into lengthened C-curve; inhale hold bend, allowing pedals to return. Imagery: Body like a rolling scroll.
【起始位】坐在踏板正前方的地板上，双脚或双腿（两个脚的人）放在椅面边缘，双手在踏板上。起始位置是骨盆微后倾，平衡位置在坐骨后方一点。 【呼吸模式】吸气时颈部延伸，肩胛下沉；吐气时手压踏板往下；当踏板往下时身体前弯，“呈现延长的弯度”；吸气保持身体弯曲，让踏板回到开始位置。 【想象】身体像一个正在卷起的卷轴。【要点】身体微后倾，靠脊柱往前绕的力去压踏杆。核心收缩造成的屈曲去压杆，而不是手。屈曲时腰椎不能往后凸。
IMAGERY 意象
【Direct】Initiation: On exhale, feel the lower ribs sliding smoothly toward the pelvis, leading the trunk into flexion. Lower Limb Stability: Maintain slight recruitment of the inner thighs to ensure legs stay firmly against the chair frame. Axial Lengthening: As the pedal returns on inhale, feel the spine 'growing taller' segmentally from the tailbone back to the balance point. 【Indirect】Taut Compound Bow: Imagine your spine as a taut compound bow, bending uniformly with consistent tension during the press. Deep Safe Harbor: Feel your abdomen as a deep safe harbor, becoming deeper and wider as the pedal descends. Pushing a Revolving Door: Imagine you are pushing a heavy revolving door, requiring steady torque from your core. 【Space】Widening to Side Walls: Imagine your back widening infinitely toward the side walls, using your breath to fill every gap between the scapulae. Grand Parabola: Feel energy rooting down from your sit bones while your crown traces a vast parabola in space. Giant Circular Space: While in flexion, imagine your crown reaching for your distant toes, creating a massive circular volume in front of your body. 【Feeling】Deep Water Resistance (Kinesthetic): Feel the pedal resistance as if moving through deep water, with every press and release accompanied by a uniform aquatic drag. Heated Wax (Texture/Kinesthetic): Imagine your spine like heated wax; while providing support, it remains supple enough to mold into the arc of the movement. Inflatable Ball Support (Tactile): As the pedal rises, feel as though your back is resting against a large inflatable ball, providing upward lift and buoyancy.
【直接】启动阶段：呼气时感受肋骨下缘向骨盆方向顺滑移动，带动躯干进入屈曲状态。下肢稳定：保持大腿内侧肌群的轻微募集，确保双腿稳固地贴合在椅子框架上。中轴拉长：在吸气让踏板回弹时，感受脊椎从尾骨向上逐节“长高”，恢复到起始的平衡点。【间接】蓄势待发的复合弓：想象你的脊柱是一把蓄势待发的复合弓，在下压过程中均匀地弯曲并充满张力。深邃的避风港：感受你的腹部像一个深邃的避风港，随着踏板的下压，这个港湾变得越来越深、越来越宽。推动旋转门：想象你正在推动一扇厚重的旋转门，需要身体核心提供持续且稳定的扭矩。【空间】向两侧墙壁拓宽：想象你的背部正在向身体两侧的墙壁无限拓宽，用呼吸去填满肩胛骨之间的所有缝隙。宽阔的抛物线：感受能量从你的坐骨向下扎根于地板，同时头顶在空间中勾勒出一个极其宽阔的抛物线。巨大的环形空间：在保持屈曲时，想象你的头顶正努力去触碰远处的脚趾，在身体前侧创造一个巨大的环形空间。【感觉】深水中的阻力（动觉）：感受踏板的阻力如同在深水中移动身体，每一次压下和回弹都伴随着均匀的流水阻力感。被加热的蜡（质感/动觉）：想象你的脊柱像被加热的蜡一样，在保持支撑的同时，能极其柔软地顺应动作的弧度变换形状。充气球的托举（触觉）：在踏板回升时，感受你的后背仿佛靠在一个巨大的充气球上，获得一种向上的托举感。
