CUES 口令
Starting position: Stand in front of barrel, sacrum at base of arc. Movement: Inhale lengthen spine, arms reach overhead. Exhale, roll spine back until hands hold first rung. Inhale lift hands, Exhale roll spine up into forward bend, Inhale roll back up to standing. Imagery: Like a rainbow arching over the barrel.
【起始位】站在桶前，骶骨在圆弧底部。【动作】吸气脊柱延伸，手臂轻轻举过头。吐气，将脊柱往后卷直到手拉住第一段附梯。吸气手抬起来，吐气，把脊柱卷起来直到往前弯的姿势，吸气卷回到站立位。【想象】像彩虹一样跨越圆桶。
IMAGERY 意象
【Direct】Inhale to prepare; on exhale, initiate from the head and neck to peel the spine segmentally off the barrel arc until standing vertically. During the roll-down, keep your weight over the balls of the feet, ensuring the pelvis doesn't shift backward. When rolling up, feel the pubic bone leading diagonally upward, restacking the spine from the tailbone. 【Indirect】Flexible Steel Tape: Imagine your spine as a flexible steel tape measure, sliding out along the arc during extension and retracting precisely and steadily to its base. Thick Cashmere Blanket: View your body as a thick cashmere blanket, conforming perfectly to the barrel's contour during the backbend, letting gravity smooth out every fold. Precision Gear Set: Imagine your body as a set of precision gears; each breath turns the wheels, driving the spinal segments in perfect engagement and transmission. 【Space】Light-Beam Stylus: Imagine your fingertips as a stylus emitting a beam of light, tracing a vast, room-spanning semi-circular arc in space. Filling the Shadowed Space: As you roll down, feel energy spilling from the crown to fill the shadowed space beneath the barrel, maximizing vertical spinal lengthening. Expanding Parasol: On inhale, imagine the ribs as a parasol opening in all directions, pushing aside the surrounding air layers to the sides. 【Feeling】Warm Deep-Sea Buoyancy (Kinesthetic): Feel the surrounding air as warm deep-sea water; every movement requires pushing through that moist, heavy buoyancy for smooth control. Warm Wax Seals (Tactile): As you extend over the barrel, imagine each vertebra leaving its own seal in a block of warm wax, clarifying spinal articulation. Abdominal Vacuum Chamber (Kinesthetic): When rolling up, feel a micro-vacuum chamber deep in the abdomen; the resulting suction instantly lightens the upper body.
【直接】吸气准备，呼气时由头颈部开始引导，将脊柱一节一节地从梯桶的圆弧面上剥离，直到身体垂直站立。向下卷动时，保持重心位于前脚掌上方，确保骨盆不向后偏移。向上卷起时，感受耻骨向斜上方引导，带动脊椎从尾骨向上逐节堆叠。【间接】柔韧的钢卷尺：想象你的脊柱是一把柔韧的钢卷尺，在伸展时顺着圆弧滑出，在回卷时精准、匀速地缩回原位。厚实的羊绒毯：视身体为一块质地厚实的羊绒毯，在后弯时完全顺应梯桶的轮廓垂落，利用自重抚平所有褶皱。精密齿轮组：想象身体是一台精密的齿轮组，每一次呼吸都在拨动齿轮，驱动脊柱各节段进行完美的咬合与传动。【空间】光束绘图笔：想象指尖是一支带有光束的绘图笔，在空间中勾勒出一个跨越房间两端的、极致宽阔的半圆弧线。填满阴影空间：在卷下时，感受能量从头顶溢出并填满梯桶下方的阴影区域，让脊柱在垂直维度上获得最大程度的延展。向四周撑开的遮阳伞：吸气时，想象肋骨像一顶向四周撑开的遮阳伞，向身体两侧推开周围的空气层。【感觉】温热深海的浮力（动觉）：感受周围空气如同温热的深海海水，每一次移动都需要推开那层温润而厚重的浮力。温热蜡块的封印（触觉）：在后弯贴合桶面时，想象每一节椎骨都在温热的蜡块上留下专属的封印。腹部微型真空室（动觉）：向上卷起时，感觉腹部深处有一个向内的微型真空室，产生的抽吸感能瞬间减轻上半身的重量。
TACTILE CUES 触觉提示
Provide stable support at sacrum; guide sternum to sink during roll up.
