The imagery that helps you create the characteristic rounded back shape in Bakasana can also help you figure out how to develop other postures that require upper body strength. For example, Chaturanga Dandasana is an important posture for developing arm power and upper body strength and the key is to focus on the back side of the body from head to tail. The work is like a less exaggerated version of the work in Bakasana and thus this video focuses on teaching you to maintain a slight backward tilt to your pelvis that resembles the tail tuck of a scolded dog, and also a slight rounded dome shape to your mid and upper back. By distinctly rounding the back side of your body you can create a stable, aligned, and safe position that is both economic and efficient. Enjoying the benefits of a rounded back shape also applies to other postures that require upper body strength such as jumping back and Bhujapidasana.
