I love this book because of its thoroughness and its simple organization. It is really useful for anybody that wants to increase their flexibility.
There are two different ways to access information in the book, both of which are very useful.
First, you can look stretches up by the area of the body. For example, if you want to increase the flexibility in your hips, back, or wrists you can just go to the appropriate section and review the stretches. There is a summary at the end that can be copied for easy reference and you always have the more detailed picture in the book to go back to if you forget how the stretch works.
Secondly, you can look up stretches by activity. So, if you play soccer regularly, you may want to add a bookmark to the soccer page. If you are playing golf for the first time in years, be sure to check out the golf page to stretch while you are out there.
This has been a great resource for me as a bodyworker since I have clients that are susceptible to repetitive stress injuries due to their work and need very localized stretches and also need small reminders for their workstations. I also have a client who complained that every time he bowls, he comes back sore and injured, so I showed him the bowling section of the book!
