（坐姿前屈折叠拉伸）是芭蕾体能训练中的坐姿前屈拉伸。舞者坐在地面上，双腿并拢向前伸直或打开至大二位。保持背部平直、脊柱拉长，从髋部折叠向前俯身，胸口贴向双腿或地面。这个拉伸作用于整个后链：背部筋膜、腰椎、腘绳肌和小腿肌肉。它是向前柔韧性、脊柱延展和下半身柔软度的重要预备练习。

Plié en Avant (Préparation au Sol) is a seated forward-fold stretch in ballet conditioning. The dancer sits on the floor with the legs together and extended straight forward, or opened into a wide second position. Keeping the back flat and the spine elongated, the dancer hinges forward from the hips, bringing the chest toward the legs or the floor. This stretch targets the entire posterior chain: the back fascia, lumbar spine, hamstrings, and calf muscles. It is an essential preparatory exercise for forward flexibility, spinal elongation, and general lower-body suppleness.
