What term describes postures in which one or both femurs are externally rotated?

The term that describes postures in which one or both femurs are externally rotated is "externally rotated standing poses." In yoga, external rotation refers to a movement where the thigh bone (femur) rotates outward, away from the midline of the body. This action is fundamental in many standing poses, as it helps align the legs properly and stabilizes the pelvis.

In externally rotated standing poses, this rotation enhances the engagement of the hip muscles, promotes proper alignment, and offers various musculoskeletal benefits. Poses like Warrior II and Extended Side Angle are prime examples where the alignment of the femurs plays a crucial role in the overall integrity and safety of the posture.

Other options such as internally rotated or neutrally rotated standing poses depict different alignment dynamics, either with the femurs rotating inward or remaining parallel to each other, which does not fit the description of the question regarding external rotation. Figuratively rotated standing poses is not a recognized term in yoga, thus highlighting the specificity and clarity associated with the terminology used in yoga practice.
