CUES 口令
Starting Position: Sit with hands on the pedal behind you (fingers forward or back) and legs extended. Keep a neutral spine with weight on the sit bones and sacrum near the chair's edge. Reverse Swan: From sitting, roll back to place hands on the pedal. Inhale to lengthen the spine and legs; exhale to engage deep abs and curl up into thoracic flexion. Inhale to return, keeping hips parallel to the floor; gaze diagonally forward during descent. Teaser I: From Teaser position, inhale to lengthen legs and torso; exhale to roll the torso away from the legs with slight spinal flexion. Inhale to return. Teaser II: Keep the upper body lifted; exhale to lower the legs and inhale to lift back to full Teaser. Teaser III: From Teaser, lower both torso and legs until parallel to the floor, then roll back up to the sit bones. Visualization: The body is like a V-shape opening and folding.
【起始位】坐姿开始，双手向后放在踏板上，手指可朝前或朝后。双脚向前伸直。脊柱中立位，重心在坐骨，骶骨在椅子上方（骶骨靠近边缘），让身体不会往后滑的位置。【Reverse Swan】以坐姿开始，身体往后卷，把手放在踏板上。吸气，脊椎与腿延伸；吐气，收紧深层腹肌开始卷上至胸椎屈曲，吸气回到原来位置，保持髋平行于地面。注意下去的时候视线看向斜前方。可以依需要调整呼吸。【Teaser I】: 最开始位置是Teaser。吸气，延伸腿与躯干；吐气，身体往后卷动，躯干远离腿，脊椎微微屈曲前弯。吸气，回到开始Teaser的位置。【Teaser II】: 保持上半身抬起，吐气时降低腿的高度。吸气，抬腿到完全的Teaser的位置。【Teaser III】: 开始位置是Teaser，躯干与腿同时往下，直到平行于地板。往上卷回到开始位置，重心在坐骨。【想象】身体像一个正在打开和折叠的V字。
IMAGERY 意象
Direct: Engage the deep transversus abdominis to initiate the curl. Keep the pelvis stable and avoid over-recruiting the hip flexors，focus on lengthening the psoas rather than gripping. Maintain a neutral cervical spine, avoiding excessive flexion or extension to protect the neck.； Indirect: Flow through the transitions with a rhythmic breath—inhale to expand and lengthen, exhale to hollow the belly. Soften the shoulders away from the ears and allow the movement to be driven by core control rather than momentum or tension in the extremities.；Space: Reach the toes toward the horizon as if trying to touch the far wall. Imagine the crown of the head and the feet pulling away from each other to create maximum space in the joints. Press the pedal down into the floor while lifting the heart toward the ceiling.； Feeling: The body is like a V shape opening and folding like a professional hand fan. Imagine your spine is a string of pearls being laid down and lifted one by one. Picture your legs as light as feathers floating in the air, while your center remains as grounded as an anchor.
【直接】启动深层腹横肌来发起卷动，保持骨盆稳定，避免髋屈肌群过度代偿（无法放长放松），重点在于伸展髂腰肌而非抓紧，保持颈椎中立，避免过度屈曲或伸展，以保护颈部。【间接】配合有节奏的呼吸流利地完成转换——吸气时延伸放长，吐气时收紧腹部，放松肩膀远离耳朵，让核心控制而非惯性或肢体张力来主导动作。【空间】脚尖向地平线远端延伸，仿佛要触碰远处的墙壁，想象头顶与双脚向相反方向拉伸，在关节间创造最大的空间。向下挤压踏板的同时，将心脏（胸腔）向天花板方向提升。【感觉】身体就像一把正在打开和折叠的专业折扇，呈现流利的 V 字型，想象你的脊椎是一串珍珠，被一颗一颗地放下和提起，想象你的双脚轻盈如羽毛漂浮在空中，而你的中心稳固如锚。
TACTILE CUES 触觉提示
Instructor places hand between client's scapulae to guide upright posture; lightly touch shins to ensure legs together and long.
导师手置于练习者肩胛骨间引导其挺拔；轻触小腿确保双腿并拢延伸；注意不能抬TA的脚，而是轻压。手放肋骨两侧，帮TA更好的屈曲。
PROGRESSION 进阶
For Reverse Swan, maintain pelvic stability while performing single-leg extensions.； For the Teaser series, incorporate small pedal pulses at the bottom of Teaser III to challenge core endurance. Focus on fluid movement and precise spinal articulation throughout each transition.
Reverse Swan 进阶： 增加踏板的阻力或在卷起时加入单腿伸展 (Single Leg Extension)。Teaser 进阶： 在 Teaser III 的基础上增加 Pedal Pumps（即保持 V 字平衡的同时，用双臂下压踏板）
REGRESSION 退阶
R- bend knees to reduce challenge.
R-若要降低挑战，可将双腿弯曲（可能要增加弹簧）。
COMMON ERRORS 常见错误
Hinging at hips or one spinal segment; excessive scapular elevation or protraction; posterior pelvic tilt.；Hip flexors unable to lengthen or relax.；Excessive cervical flexion or extension.
以髋关节或单节脊柱为折点；肩胛过度上提或前引；骨盆后倾。髋屈肌群无法放长放松；颈椎过度屈曲或伸展
PRECAUTIONS 注意事项
Acute lumbar conditions; coccyx injury; overactive hip flexors.
急性腰椎病症；尾骨损伤；髋屈肌过度活跃者。
