SETUP 设置
Springs: 1/2-1; foot bar flat; sit on carriage facing back, legs extended.
【弹簧】1/2-1根；脚棒放平；坐在滑板上，面向后端，双腿伸直。
CUES 口令
Starting position: Sit tall, trunk neutral. Hold loops, elbows bent, hands on carriage near greater trochanter. Breathing (variation 1): Exhale flex spine, hands slide forward on carriage toward feet. As arms extend forward, inhale to lift body to long sitting, trunk upright. Arms reach toward ceiling. Exhale arms circle out and back to start. Cue: Roll smoothly.
【起始位】坐姿，躯干中立位。手抓套环，手肘弯曲，手心在床上靠近髂骨大转子。【呼吸（变式1）】吐气：脊椎前弯屈曲，手沿着床往前滑，往脚的方向延伸。于手臂前端延伸，同时吸气，身体抬起到长坐姿势，躯干直立位置。手臂往天花板方向延伸。吐气：手臂往两侧往后绕，回到起始位置。【提示】卷动过程要顺滑。
IMAGERY 意象
【Direct】As you exhale and roll down, keep the sacrum vertical to the carriage, starting with a slight chin tuck and guiding the spine vertebra by vertebra toward the toes. While stretching the arms upward, maintain a stable connection between the lower rib margin and the pelvis to prevent excessive lumbar lordosis. When circling the arms to the sides, focus on the scapulae gliding smoothly against the back of the ribs without shrugging toward the ears. 【Indirect】Surging Fountain: Imagine your body as a surging fountain, with energy rising from the base of the sit bones, arching over the top of the spine, and cascading lightly forward through the fingertips. Drawn Bow: The torso is like a fully drawn bow; the abdomen is the resilient string pushing the spine posteriorly into a rounded full-moon shape. Folding Fan: On inhalation to return to an upright position, feel the spine like a delicate folding fan closing, tightening and stacking in an orderly fashion from the bottom up. 【Space】Passing Through a Low Window: Feel as if you are trying to dive through a very low semi-circular window, extending the body infinitely forward into space as you pass through. Deep Cave: During the downward roll, imagine the abdomen hollowing inward to create a deep cave, making significant internal space for the spine's flexion. Touching Cosmic Boundaries: As the arms circle, feel the fingertips attempting to pierce the air's resistance to touch the four most distant diagonal corners of the room. 【Feeling】Magnetic Effect (Tactile): Upon inhaling to stand tall, feel a powerful attraction between the center of your crown and a magnet on the ceiling, instantly restoring a vibrant sense of verticality. Warm Clay (Kinesthetic): As the arms move through space, feel as if you are kneading warm, lightweight clay; every stroke carries a uniform, steady, and plastic resistance. Guqin Resonance (Auditory): As you exhale downward, listen internally for a deep 'mmm' sound, feeling the vibration of intra-abdominal pressure spreading steadily like ripples from the core.
【直接】吐气卷动时，保持骶骨垂直于滑车，由下巴微收开始，将脊柱一节一节地引向脚趾方向。在双臂向上伸展时，维持肋骨下缘与骨盆的稳定连结，防止腰椎产生过度前凸。手臂向两侧绕环时，专注于肩胛骨平贴在肋骨后侧平滑移动，不要让肩膀耸向耳朵。【间接】涌动的喷泉：想象身体是一座涌动的喷泉，能量从坐骨基底升起，翻过脊柱顶端，再顺着指尖向前方轻盈洒落。拉满的强弓：躯干如同一张拉满弦的强弓，腹部是那根坚韧的弦，正将背部脊柱向后推成圆润的满月状。合拢的折扇：吸气还原直立位时，感觉脊柱像一把正在合拢的精细折扇，由底部向上有序地收紧、堆叠。【空间】穿越低矮窗口：感觉正试图钻过一个极低矮的半圆形窗口，身体在钻过去的同时，努力向空间的前方无限延伸。深邃的洞穴：在向下卷动时，想象腹部向内凹陷制造了一个深邃的洞穴，为脊柱的屈曲腾出巨大的内部避震空间。触摸宇宙边界：手臂画圆时，感觉指尖正试图划破空气的阻隔，触摸到房间最远端的四个对角线顶点。【感觉】磁吸效应（触觉）：吸气直立时，感觉头顶中心与天花板上的磁铁产生强力吸引，带着你瞬间恢复充满活力的垂直感。温热的黏土（动觉）：手臂在空间中移动时，感觉像在揉捏温热的轻质黏土，每一次划动都带有均匀、沉稳且具有可塑性的阻力。古琴的余韵（听觉）：吐气向下时，内心听听那低沉的‘嗡（mmm）’声，感受腹内压的震动像水波一样从核心向四周稳定扩散。
TACTILE CUES 触觉提示
Hand on abdominals to cue deep engagement; lightly touch spine to guide sequential flexion; guide smooth arm circle path.
手置于腹部提示深层收缩；轻触脊椎引导逐节前弯；引导手臂绕环的圆润轨迹。
PROGRESSION 进阶
