BENEFITS 益处
Improves postural awareness; improves hip mobility; strengthens shoulders and core; challenges trunk stability in sagittal and frontal planes.
改善姿态的察觉能力；改善髋关节活动能力；增强肩膀与核心的力量；挑战躯干在矢状面和冠状面的稳定性。
TARGET MUSCLES 目标肌群
Obliques (anti-rotation stability), transversus abdominis and multifidus (maintain trunk neutral), hip flexors (iliopsoas, etc.) and extensors (gluteus max, hamstrings) (forward/back swing), hip abductors (gluteus medius) (up/down movement), shoulder girdle stabilizers (serratus anterior, lower trapezius, etc. for support).
腹斜肌（抗旋转稳定）、腹横肌与多裂肌（维持躯干中立）、髋屈肌（髂腰肌等）与髋伸肌（臀大肌、腘绳肌）（前后摆动）、髋外展肌（臀中肌）（上下动作）、肩带稳定肌群（前锯肌、下斜方肌等维持支撑）。
SETUP 设置
None. May place pillow under head for support and cervical alignment.
无。可在头下放置枕头以支撑头部，改善颈椎排列。
CUES 口令
Starting position: Side-lying, bottom elbow on floor under shoulder. Top hand on floor in front of chest. Hips stacked, waist lifted off floor, spine neutral. Legs long in line with trunk, or slight hip flexion allowed. Top leg lifted parallel to floor. Breathing/Movement: Forward/Back: Inhale, top leg flexes forward, foot dorsiflexed, pelvis neutral. Exhale, top leg extends back, foot plantarflexed, neutral. Up/Down: Inhale, top leg abducts up, pelvis stable. Exhale, control leg down. Imagery: Trunk like a sturdy lighthouse, legs as pointers swinging around it; during forward/back, imagine sit bones reaching long.
起始位：侧卧，下方手肘撑地，与肩膀对齐。上方手在胸前地面支撑。双髋对齐，腰线抬离地面，脊椎中立。双腿伸直与躯干对齐，或允许髋部微屈。上方腿抬高与地面平行。 呼吸与动作： 前后摆动：吸气，上方腿向前做髋屈动作，脚背屈，保持骨盆中立。吐气，上方腿向后做髋伸动作，脚跖屈，保持中立。 上下动作：吸气，上方腿外展抬高，骨盆保持稳定。吐气，上方腿有控制地收回。 想象提示：想象躯干是坚固的灯塔，双腿是围绕它摆动的指针；腿前后摆动时，想象坐骨向远处延伸。
IMAGERY 意象
Direct: Feel hip joint sliding in socket forward/back and up/down. Indirect: Like a stable boat, hull (trunk) still, oars (legs) moving in water. Space: Imagine a stable space between trunk and floor, not compressed by leg movement. Feeling: Focus on pressure in supporting elbow, engagement of bottom waist, and movement of top hip.
直接：感受髋关节在球窝中前后上下滑动。间接：像一艘稳固的船，船舷（躯干）不动，船桨（腿）在水中划动。空间：想象躯干与地面之间有一个稳定的空间，不被腿部动作挤压。感觉：注意力放在支撑侧的手肘压力、下方侧腰的发力感，以及上方髋关节的活动感上。
TACTILE CUES 触觉提示
1. Lightly place hand on top hip, cue to stay stable, no rocking or rotation. 2. Lightly touch bottom waist, cue abdominal engagement to maintain height. 3. During forward/back swing, lightly touch sit bones and heel, guide to reach long. 4. During up/down, lightly touch lateral top thigh, guide initiation from hip, not trunk.
1. 一手轻放在练习者上方的髋部，提示其保持稳定，避免前后晃动或旋转。2. 一手轻触其下方侧腰，提示收紧腹部以维持腰线高度。3. 在腿前后摆动时，轻触其坐骨和脚跟，引导向远延伸。4. 在上下动作时，轻触其上方大腿外侧，引导用髋部发力而非躯干。
PROGRESSION 进阶
1. Top hand does not support, hovers or rests on side. 2. Increase repetitions to challenge endurance.
1. 上面的手不支撑地面，悬空或放在体侧。2. 增加动作次数以挑战耐力。
REGRESSION 退阶
1. Bend one or both knees to shorten lever, reduce core demand. 2. Support head fully with arm or pillow. 3. Start leg slightly forward to increase contact area with floor for stability. 4. If trunk control weak due to pregnancy or low back pain, bend knees.
1. 单膝或双膝弯曲，缩短力臂，降低对核心的要求。2. 侧卧时，头部用手臂或枕头充分支撑。3. 腿开始的位置稍往前一点，以增加身体与地面的接触面积，提高稳定性。4. 由于怀孕或下背疼痛导致躯干控制力弱时，可弯曲膝盖。
COMMON ERRORS 常见错误
Pelvic wobble; lumbar flexion or extension; cervical or thoracic lateral flexion; over-recruiting hip flexors/extensors to assist stability, causing stiffness; shoulder collapse; trunk rotating or tilting with leg movement.
骨盆晃动；腰椎前屈或后仰伸展；颈椎或胸椎侧屈；过度募集髋屈/伸肌群来协助稳定，导致动作僵硬；肩膀塌陷；上方腿动作时躯干随之旋转或侧倾。
PRECAUTIONS 注意事项
For shoulder pain, lie side-lying with head support. For lateral hip pain, place pillow under hip or near greater trochanter. For pregnancy, place pillow under belly as needed. No absolute contraindications.
肩膀疼痛者可侧卧，头部给予支撑。髋部侧边疼痛者可在髋下方或股骨大转子附近放枕头。怀孕者可根据需要放枕头在肚子下方。无绝对禁忌症。
