Did you know that yoga benefits every system in the body, from joints to hormone response, digestion, and brain function? Science of Yoga uncovers the facts and explains how to get the most from your practice. Each asana is demonstrated with artworks that reveal the muscle and joint actions below the surface, safe alignment, and much more. This expanded edition features therapeutic sequences tailored to help relieve common problems, such as back pain, arthritis, and anxiety, including poses that can be performed in a chair.
