Side Crane has been my arch nemesis now for several years. Finally, I can do it with confidence! I will be the first person to tell you that it takes a lot of practice to be able to get into this pose and hold it steadily. But the feeling of success you get once done......So excited!!
This pose is great for wrist and arm strengthening and, as you can tell in the picture, for working on your balance.
The Yoga Journal has an excellent step-by-step guide for how to get into this pose, as it is very complicated, and I cannot explain it better myself!
Practice, practice, practice!
