BENEFITS 益处
Strengthens core (especially obliques) and shoulder girdle stability; improves thoracic rotation mobility; enhances body control and coordination in side support.
强化核心肌群（尤其是腹斜肌）和肩带稳定性；改善胸椎旋转的活动度；提高身体在侧向支撑下的控制与协调能力。
TARGET MUSCLES 目标肌群

腹内斜肌、腹外斜肌（主导旋转与稳定）、腹横肌（深层稳定）、前锯肌与下斜方肌（肩胛稳定）、臀中肌（稳定髋部）、三角肌（支撑与抬臂）。
SETUP 设置
None.
无特殊器械调节。
CUES 口令
Starting position: Side-sit (reverse sit), bottom hand on floor under shoulder. Legs alongside body, top foot in front of bottom foot for base. Breathing/Movement: Exhale, lift hips up, reaching top arm toward ceiling into side plank variation. Then, initiate from ribs, rotate trunk toward floor, top arm reaching down. Feel hips pressing toward ceiling. Inhale, rotate back, arm reaching to ceiling, chest open. Eyes follow top hand. Repeat 3-5x, then control return to start, switch sides. Imagery: Body like a door, pivoting on supporting arm, opening and closing gracefully; during rotation, imagine light shining from chest, illuminating floor and sky.
起始位：侧坐（倒坐），下方手撑地，手在肩正下方。双腿在身体旁侧，上方脚放在下方脚的前方（增加支撑面）。 呼吸与动作：吐气，将髋部向上抬起，同时上方手臂向天花板方向延伸，进入侧平板支撑变体。然后，从肋骨开始引导，向地板方向旋转躯干，上方手臂随之向身体下方延伸。感受髋部持续向天花板方向推。吸气，身体往回旋转，手臂回到向天花板延伸，胸口打开。眼睛始终跟随上方手。重复3-5次后，有控制地回到起始位，换边练习。 想象提示：想象身体像一扇门，以支撑臂为轴，优雅地开合；旋转时，仿佛有一束光从胸口射出，照亮地板和天空。
IMAGERY 意象
Direct: Feel strong contraction of opposite oblique and stable support of shoulder girdle. Indirect: Like a lighthouse, base (pelvis/support arm) stable, top (ribcage/arm) rotating freely. Space: Imagine body sandwiched between glass plates, rotating parallel to them. Feeling: Focus on bottom arm pressing into floor, core engagement, and smooth rotation of thoracic spine driving the arm.
直接：感受对侧腹斜肌的强烈收缩和支撑侧肩带的稳定支撑。间接：像一座灯塔，底座（骨盆与支撑臂）稳固，顶部（胸廓与手臂）自由旋转。空间：想象身体被夹在两块透明的玻璃板之间，旋转时始终与玻璃板平行。感觉：注意力放在支撑臂推地的力量、核心收紧维持平板的感觉，以及胸椎旋转带动手臂的流畅感上。
TACTILE CUES 触觉提示
1. Lightly place hand on top hip, cue to lift and stabilize. 2. Lightly touch ribs on rotation side, guide initiation. 3. During rotation, lightly touch top arm, guide to reach long. 4. Lightly touch bottom scapula, cue to stay stable and depressed.
1. 一手轻放在练习者上方髋部，引导其向上推起和保持稳定。2. 一手轻触其旋转方向的肋骨，引导旋转的启动。3. 在旋转时，轻触其上方手臂，引导其向远延伸。4. 轻触其下方支撑臂的肩胛骨，提示其保持稳定下沉。
PROGRESSION 进阶
1. Place top leg behind to increase rotation range and core challenge. 2. Briefly hold at end of rotation. 3. Increase tempo while maintaining control.
1. 上方腿置于后方，增加旋转幅度和对核心的挑战。2. 在旋转到位后短暂停留。3. 加快动作节奏，保持控制。
REGRESSION 退阶
1. Prep: both hands on floor, practice trunk rotation. 2. Keep top hand on floor, perform only hip lifts and small trunk rotation. 3. Reduce hip lift range. 4. Support on both knees to reduce difficulty.
1. 预备式：双手都在垫上支撑，先练习躯干的旋转。2. 上方手不抬离地面，仅做髋部的起伏和躯干的微小旋转。3. 减小髋部抬起的幅度。4. 双膝跪地支撑，降低难度。
COMMON ERRORS 常见错误
Shoulder elevation, humeral head protraction; excessive wrist pressure; foot supination or ankle collapse; body collapsing toward floor in side plank (core instability); rotating with shoulders/arms instead of initiating from ribs.
肩膀上提，肱骨头前突；手腕关节过度受压；脚旋后或踝关节塌陷；在侧平板位置身体向地板塌陷（核心失稳）；旋转时用肩膀和手臂代偿，而非从肋骨启动。
PRECAUTIONS 注意事项
Caution or regress for wrist pain, rotator cuff injury, acute lumbar disc herniation. For hypertension, avoid breath holding.
手腕疼痛、肩袖损伤、腰椎间盘突出急性期者慎做或降阶。高血压患者注意避免憋气。
