Query: good with some flaws

This is a good book with some flaws. The exercises are great. However, once you determine which type of exercises you need and go to the list, there are no page numbers (only names of the exercises) which would have allowed you to easily refer back to the page that the particular exercise description is on. This makes it extremely frustrating to have to flip back and forth to find the needed exercise. I ended up putting lots of post it notes in the book with page numbers sticking out. This could have very easily been avoided with the addition of page numbers on the exercise list. Also, several exercises do not have illustrations making it difficult (unless you are a trainer or physical therapist) to know if you are really doing it correctly. ALL of the exercises should have had illustrations.
