BENEFITS 益处
Improves spinal rotation mobility; strengthens obliques control; improves posture; enhances dissociation between pelvis and ribcage in rotation.
改善脊椎旋转的活动度；增强腹斜肌力量与控制；改善姿态；提高骨盆与胸廓在旋转中的解离能力。
TARGET MUSCLES 目标肌群
Internal/external obliques (primary rotators), multifidus and rotatores (spinal rotation control), transversus abdominis (deep stabilizer), erector spinae (maintain axial elongation).
腹内斜肌、腹外斜肌（主导旋转）、多裂肌与回旋肌（脊椎旋转控制）、腹横肌（深层稳定）、竖脊肌（维持中轴延伸）。
SETUP 设置
None. May sit on box or cushion to help maintain pelvic neutral.
无。可坐在箱子或垫枕上以帮助维持骨盆中立。
CUES 口令
Starting position: Long sit, legs slightly apart or together. Pelvis, spine, head neutral. Arms extended out to sides at shoulder height. Breathing/Movement: Inhale, lengthen spine. Exhale, keeping pelvis stable, rotate from ribcage, turning shoulders, head, neck, and eyes to the right smoothly. Inhale, control return to center. Exhale, rotate left. May switch breath. Imagery: Pelvis as stable lighthouse base, ribcage as rotating lantern; sternum like a compass needle pointing precisely sideways.
起始位：长坐姿势，双腿略微外展与肩同宽，或并拢。骨盆、脊椎与头部保持中立位。双臂向身体两侧水平延伸，与肩同高。 呼吸与动作：吸气，脊椎向上延伸。吐气，保持骨盆稳定不动，从胸廓（肋骨）开始，带动肩膀、头、颈和眼睛，向右侧匀速旋转。吸气，有控制地转回面向正前方。吐气，向左侧旋转。可交换呼吸模式（如旋转时吸气，回正时吐气）。 想象提示：想象骨盆是稳固的灯塔底座，胸腔是旋转的灯头；旋转时，想象胸骨像指南针的指针，精准地指向侧方。
IMAGERY 意象
Direct: Feel opposite oblique contracting, same-side oblique stretching. Indirect: Like a lighthouse, base still, top rotating freely. Space: Imagine ribcage volume unchanged during rotation. Feeling: Focus on even pressure of sit bones and alignment of sternum with pubis.
直接：感受对侧腹斜肌的收缩和同侧腹斜肌的拉伸。间接：像一座稳固的灯塔，底座不动，顶端自由旋转。空间：想象胸腔在旋转时容积保持不变。感觉：注意力放在两侧坐骨均匀压地的感觉，以及胸骨与耻骨的对齐上。
TACTILE CUES 触觉提示
1. Lightly place hands on client's pelvis, cue to stay stable, avoid rotating. 2. Lightly touch scapula on rotation side and opposite ribs, guide coordinated rotation. 3. Lightly touch sternum, cue it as the center pointer.
1. 双手轻放在练习者骨盆两侧，提示保持稳定，避免旋转。2. 一手轻触其旋转方向的肩胛骨，一手轻触其对侧肋骨，引导旋转的联动。3. 手指轻触其胸骨，提示其作为旋转的中心指针。
PROGRESSION 进阶
1. Hold Pilates ring or bar to increase lever, challenge core control. 2. Cross arms on chest to increase rotation range demand. 3. Perform with eyes closed to enhance proprioception.
1. 手握普拉提圈或传力杆，增加力臂，挑战核心控制。2. 手臂交叉于胸前，增加旋转幅度要求。3. 闭眼练习，增强本体感觉。
REGRESSION 退阶
1. Bend knees, cross feet or sit in diamond to reduce pelvic stability demand. 2. Sit on box to help pelvic alignment. 3. Reduce rotation range. 4. Keep legs parallel, not necessarily apart.
1. 膝盖弯曲，双脚交叉或呈菱形坐姿，降低对骨盆稳定性的要求。2. 坐在箱子上，帮助骨盆正位。3. 减小旋转幅度。4. 双腿平行伸直，不要求外展。
COMMON ERRORS 常见错误
Loss of axial length (shortening); one sit bone lifting (pelvic wobble); pelvis rotating with spine; leading rotation with head or arms instead of ribcage; shoulder shrugging.
失去中轴长度（身体缩短）；一侧坐骨离地（骨盆晃动）；骨盆跟随旋转；以头部或手臂带动旋转，而非胸廓；耸肩。
PRECAUTIONS 注意事项
Caution for acute lumbar disc herniation, severe osteoporosis, avoid large rotation. Caution in late pregnancy.
腰椎间盘突出急性期、严重骨质疏松者需谨慎，避免大幅度旋转。怀孕后期慎做。
