（地面推手后下腰），又称蛇式伸展或地面 Cambré，是芭蕾体能训练中的俯卧脊柱后伸练习。舞者俯卧在地面上，双手放在胸旁，将上半身向上推起，胸椎后弯、头部后仰。胸口提起打开，下半身保持稳定贴地。这个练习增强脊柱后伸柔韧性——这对芭蕾中的 Cambré（下腰）动作至关重要——同时拉伸腹部肌肉和髋屈肌。它为古典变奏和 Adagio 所需的深度后腰做好准备。

Extension du Dos, also known as the Sphinx pose or cambré au sol, is a floor-based back extension exercise in ballet conditioning. The dancer lies prone on the floor and places the hands beside the chest, then presses the upper body upward, arching the thoracic spine and tilting the head back. The chest lifts and opens while the lower body remains grounded and stable. This exercise increases spinal extension flexibility, which is necessary for cambré (backbend) movements in ballet, and stretches the abdominal muscles and hip flexors. It prepares the spine for the deep backbends required in classical variations and adagio work.
