The next movement of the hips we will explore is external rotation. This movement is subtler than flexion or extension. However, external rotation plays a big role in yoga practice. External rotation of the hip is needed for challenging postures like Leg Behind the Head, but is also needed for all seated postures. For this reason it plays a big role in enabling pranayama and meditation practices. It is a physical skill that is needed for practices that take us beyond the body.
Muscles of External Rotation
External rotation is when the leg bone (femur) rotates away from the body. There are a lot of muscles that facilitate this motion, and any one of them can give us trouble. These muscles include: piriformus, quadratus femoris, two obdurators and the gemelli. (The gluteus maximus also aids in external rotation.)
External rotation is not particularly difficult when standing. Most of us have no problem pointing the toes of one or both feet out to the sides. However, this action is complicated quite dramatically once we had hip flexion.

The Difficulty of Seated Postures
In many seated yoga postures, difficulty arises in the fact that we are not only externally rotating the hip like a ballerina in turnout. We are also flexing the hip. When we externally rotate and flex the hip, the muscles of external hip rotation have to lengthen. This is where we run into trouble. If any of the muscles of external rotation are tight, this movement becomes difficult. |

In cultures that sit on the floor, external rotation is not a challenging movement. For those who sit in chairs, this movement is much more challenging. It can take time to develop this skill.
