While David could use a good copy editor (there are a lot of typos and grammatical errors) this is the most user-friendly yoga book I've seen. The layout and copy content make it a very useful practice companion. I think it is best suited for someone with previous yoga experience. I would still recommend Beryl Bender Birch's Power Yoga to a beginner. She discusses various pose modifications at length; a beginner might find that more useful than the quick easy layout and helpful reminders found in David's book. Since David's book is great for a continuing practice, the two books really go well together.
