Archer Pose (Akarna Dhuanurasana) is one of those poses that looks easy but can be challenging for many. This variation crosses the upper foot across the body. There is another variation in which the foot is pulled towards the ear on the same side of the body. Both variations require a great deal of hip flexibility. It is helpful to attempt this pose after warming up with some hip- and shoulder-openers, twists, and hamstring stretches.
