Crow pose is one of the first arm balances introduced in yoga classes and as a yoga teacher, one of the poses that I am asked the most about how to execute. In order to do this pose, you not only need upper-body strength, but you also need core strength and to let go of the fear of lifting the feet off of the floor. Crow pose has a lot to do with strength, but it also has a lot to do with believing that you can do it. Whether you try this pose once or a hundred times, keep believing that you can and you will eventually lift off into crow pose.
When you first start trying this pose, try putting a blanket in front of your mat as a “landing pad.” This will help you to not worry as much about falling forward.
