CUES 口令
Starting position: Supine, legs lifted to 90/90 tabletop. Spine neutral or with slight lumbar curve. Arms open to sides ~45°. Breathing/Movement: Inhale, rotate feet and pelvis to right. Exhale, control back to center. Inhale, rotate left. Exhale, return. Repeat 3-5x each side, keeping scapulae on mat. Rotation + Stretch: At full rotation, lower legs to floor, turn head opposite, hold 2-3 breaths. Advanced: straighten knees in this position. Imagery: Pelvis like a steering wheel axle, turning steadily; spine like a flexible rope, rotating evenly from bottom up.
起始位：仰卧，双腿抬起呈90/90桌面姿势。脊椎可选择腰椎微微前弯或保持中立位。手臂向身体两侧打开约45度角。 呼吸与动作：吸气，将双脚和骨盆向右侧旋转。吐气，有控制地转回中间。吸气，向左侧旋转。吐气，转回中间。每侧重复3-5次，过程中保持肩胛贴住垫子。 旋转加伸展：在完全旋转至一侧时，将腿放到地板上，头转向另一侧，保持姿势呼吸2-3次。进阶可在此位置将膝盖伸直。 想象提示：想象骨盆像方向盘的转轴，稳定地左右转动；脊椎像一根灵活的扭绳，从下至上均匀旋转。
IMAGERY 意象
Direct: Feel ribcage and pelvis turning like meshed gears. Indirect: Like a soft ribbon, twisting evenly from center out. Space: Imagine small spaces between vertebrae gently opening during rotation. Feeling: Focus on contraction of opposite oblique and stable contact of scapulae on mat.
直接：感受胸廓和骨盆如齿轮般啮合转动。间接：像一根柔软的丝带，从中心向两端均匀扭转。空间：想象脊椎旋转时，每节椎骨之间的小空间被轻柔地打开。感觉：注意力放在对侧腹斜肌的收缩感和肩胛稳定贴地的感觉上。
TACTILE CUES 触觉提示
1. Lightly place hands on acromia, cue to stay on mat. 2. One hand on sacrum, one on knees, guide synchronized rotation. 3. At full rotation, lightly touch lateral waist, cue rib involvement.
1. 双手轻放在练习者两侧肩峰，提示其保持贴地。2. 一手轻触其骶骨，一手轻触其膝盖，引导同步旋转。3. 在旋转至一侧时，轻触其腰部侧方，引导肋骨参与旋转。
PROGRESSION 进阶
1. Full pendulum: straighten knees. 2. Rotate with one or both legs straight. 3. At full rotation, straighten knees then return to bent.
1. 全钟摆运动：膝盖伸直做Side To Side。2. 单脚或双脚伸直进行旋转。3. 在旋转至一侧时伸直膝盖再收回。
REGRESSION 退阶
1. Keep feet on floor. 2. Reduce range of motion. 3. Draw knees closer to chest to shorten lever. 4. Elevate upper body with pillow/wedge.
1. 保持脚放在地板上做动作。2. 减小活动范围。3. 让膝盖靠近胸口方向，缩短力臂。4. 用枕头或楔形枕垫高上半身。
COMMON ERRORS 常见错误
Excessive hip flexion; overusing shoulders; excessive cervical extension or flexion; shoulder shrugging or protraction; poor head/neck alignment; anterior pelvic tilt; head pressing into mat.
髋关节过度屈曲；肩部过度用力；颈椎过度后仰伸展或屈曲；耸肩或肩胛前引；头颈部排列不良；骨盆向前倾；头部下压垫子。
PRECAUTIONS 注意事项
Avoid extreme spinal rotation and force with osteoporosis; in late pregnancy, elevate with pillow or support feet.
骨质疏松症者避免极端的脊椎旋转与外力；怀孕后期可用枕头垫高或脚有支撑。
