I love that this book has practices from 5-90 minutes but the instructions and illustrations may be too succinct for some. For instance, the locust pose has virtually no instructions and the stick figure just barely illustrates the pose. The poses generally don't mention modifications beyond the advice to bend the knees in forward bending if you're inflexible. For those with some experience the pared down written instructions and stick figures may be sufficient cues for practicing.

The preface to each practice is wise and light-hearted, as is the overall tone of the book, which lies nicely flat for ease of use.

I bought this as a beginning yoga practitioner and have used it extensively, particularly for the 15 and 30-minute sessions. I haven't tried the longer sessions yet for one reason: I lose the flow of the poses when I have to flip back and forth between the portion that shows all poses and the portion that shows each pose in more detail. Do I inhale or exhale here? It doesn't say in the section showing many poses, so I have to stop, flip back to the details, then start again. Sounds minor and it is, but it (and occasionally confusing drawings, as with "Threading the Needle") are drawbacks to what is otherwise a very useful book. I particularly like the spiral binding so the book lies open for easy reference during practices.
