This pose is also known as leg under armpit pose and is the natural progression of a contortionist furthering their leg behind head practice. This pose relies on a much greater depth of stretch in the hip joint than its parent position. It is for this reason that practitioners need to be careful as they start to progress to this next level. A contortionist’s proportions affect the way that they execute positions. This is definitely no exception. Those with longer legs might find it easier as the leg is more easily accessible. Another key flexibility component for this pose is shoulder flexibility. Your shoulder must be flexible enough to make space for the leg to be placed under the arm.
