I love this whole series. The illustrations are perfect - detailed enough that you can really tell what you're looking at but not overwhelming. I have a weekly yoga session with a couple of friends and we've been picking one pose a week to work through, using all the instructions. Sometimes all we can do is stare at the illustration, imagine where the muscle is on our bodies, and work on the intention to flex or extend it. But over weeks of working with it, we're all finding movement where there was none before. I'm also thrilled with how much anatomy I'm absorbing through the pose illustrations and instructions.
