后交叉阿提丢德（含各学派差异）
意为「交叉于身后的 attitude」（attitude crossed in back）。舞者面向舞台的一个前角站立（croisé 方向），离观众最近的腿为支撑腿。抬起的腿以 90 度保持在身体后方交叉，膝弯成直角，脚与抬起的膝盖持平或略低于膝盖。身体以四分之三侧面的角度呈现于观众。
各学派在躯干与头部的处理上有所不同：
【切凯蒂体系】身体直立、后背挺直，双肩摆正并用力压沉。头转向高举的手臂一侧，目光顺着抬起的手心向上看。
【法兰西学派】身体朝支撑腿方向弯折，抬起手臂一侧的肩膀略高于另一侧肩。头转向朝前的一侧肩。
【俄罗斯学派】身体前倾，背部呈优美的拱形。双肩对齐并向下压沉，头转向朝前一侧的肩。俄罗斯学派还采用一种高位 croisé 姿势，即脚抬得高于膝盖。
Attitude crossed in back. The dancer stands facing a front corner of the stage (croisé direction) with the supporting leg nearest the audience. The raised leg is held at 90 degrees and crossed behind the body with the knee bent at a right angle and the foot held parallel or slightly below the raised knee. The body presents a three-quarter view to the audience.
The schools differ in the treatment of the torso and head:
[Cecchetti method] The body is held upright with a straight back, shoulders aligned and well pressed down. The head is turned with the eyes looking up into the palm of the raised hand.
[French School] The body is bent toward the supporting leg with the shoulder of the raised arm lifted slightly higher than the other shoulder. The head is turned toward the front shoulder.
[Russian School] The body inclines forward with a well-arched back. The shoulders are aligned and pressed down with the head turned toward the front shoulder. The Russian School also uses a high croisé position in which the foot is raised higher than the knee.
