【起始位】[Off]Knee Stretch位膝离地；[Arabesque]一脚在滑板膝遮开，另一脚抬向后上方。【呼吸】[Off]吐气腹肌收缩回拉；[Arabesque]吸气下方腿屈曲拉回滑板，上方腿向天花板延伸。【提示】身体像展翅的飞鸟。
IMAGERY 意象
[Knee Stretch Knees Off]【Direct】Keep the shins parallel to the carriage surface at all times, feeling the pressure evenly distributed between the heels of the hands and the balls of the feet. During the carriage back-and-forth movement, focus on the rotation of the femur within the acetabulum, ensuring no change in spinal alignment. 【Indirect】Horizontal Scanner: Imagine your torso is a high-precision horizontal scanner translating steadily back and forth on its track without any vertical fluctuation or vibration. Crouching Leopard: The body is like a leopard crouched and ready to spring, with limbs filled with static tension, prepared to power the carriage away. 【Space】Low Glass Dome: Feel as if you are confined under a low glass dome; during movement, your back must stay close to the top of the dome without breaking it to maintain a very low and constant height. Parallel Laser Lines: Imagine two parallel horizontal lasers emitting from your knees; as the carriage moves, the laser dots on the wall must trace a horizontal line at a constant height. 【Feeling】Fragile Eggshell: Imagine a paper-thin eggshell floating beneath your abdomen; as you pull the carriage back, use core support to protect it from being crushed. Maglev Sensation: Feel a zero-friction maglev state between the carriage and the rails, making every glide feel as light and unobstructed as moving through air. [Arabesque]【Direct】Guide the toes of the floating leg to extend continuously toward the back-diagonal ceiling while reaching the center of the crown in the opposite forward-diagonal direction. Keep the kneecap of the supporting leg facing forward, ensuring the pelvis remains horizontally aligned during single-leg loading. 【Indirect】Balance Needle: Imagine your body as a giant balance needle pivoting on the hip joint of the supporting leg; as the carriage opens, the needle points precisely into the deepest part of the space. Arrow from a Bow: The floating leg is like a long arrow just released, carrying the body's energy through the room's walls into infinite external space. 【Space】Vertical Slice: Use the trajectory of the floating leg to carve a perfect vertical slice in space, neatly dividing the room into left and right halves. Reaching the Zenith Corner: Strive to touch the highest and farthest corner behind the room with your floating toes, infinitely elongating the body along the diagonal. 【Feeling】Warm Silk Thread: Feel the ankle of the floating leg being guided by a warm silk thread, gently lifted from the ceiling, making your leg feel almost weightless. Deep Sea Gliding: Imagine you are swimming slowly in the deep sea; the water's resistance requires you to use deep muscle groups to steadily control the carriage's return, preventing it from hitting the stoppers.
[Knee Stretch Knees Off]【直接】保持胫骨始终与滑车表面平行，感受掌根与脚球在器械上均匀分布的压力。在滑车往返移动时，专注于大腿骨头在髋臼窝内的转动，确保脊柱排列不产生任何变动。【间接】水平扫描仪：想象你的躯干是一台高精度的水平扫描仪，在轨道上匀速前后平移，不产生任何上下的起伏或震动。蓄势待发的猎豹：身体像是一只伏地待发的豹子，四肢充满了静止的张力，随时准备将滑车有力地推向远方。【空间】低矮玻璃罩：感觉你被困在一个低矮的玻璃罩内，在移动过程中，你的背部必须时刻贴近罩顶但不能顶碎它，以维持极低且恒定的高度。平行激光线：想象从你的双膝射出两道平行的水平激光，在滑车移动时，激光在墙上的光点轨迹必须保持在同一高度的水平线上。【感觉】脆弱的蛋壳：想象你的腹部下方漂浮着一个薄如蝉翼的蛋壳，在拉回滑车时，要利用核心的支撑力保护它不被压碎。磁悬浮感：感觉滑车与轨道之间是零摩擦的磁悬浮状态，每一次推移都像在空气中滑动般轻盈且无阻滞感。[Arabesque]【直接】引导浮腿的脚趾持续向斜后上方延伸，同时让头顶中心向相反的前上方对拉。保持支撑腿的膝盖骨正对前方，确保骨盆在单腿负重时依然维持水平对齐。【间接】天平指针：想象你的身体是一根巨大的天平指针，以支撑腿的髋关节为轴心，随着滑车的推开，指针精准地指向空间的最深处。离弦的长箭：浮腿像是一支刚刚射出的长箭，带着全身的能量穿过房间的墙壁，射向无穷远的外部空间。【空间】垂直切片：用浮腿的轨迹在空间中划出一道完美的垂直切痕，将房间左右两半的空间整齐地分开。触碰天顶角：努力用你的浮腿尖去触碰房间后方那个最高、最远的顶角，让身体在对角线上无限拉长。【感觉】温热的丝线：感觉浮腿的踝关节被一根温热的丝线牵引，由天花板上方轻柔地拉起，使你的腿部感觉几乎没有重量。深海潜行：想象你在深海中缓慢游动，海水的阻力要求你必须利用深层肌群缓慢而稳健地控制滑车的往返，防止撞击挡块。
