Query: a disapointment

I was really looking forward to using this book, but unfortunately it was a disappointment. Its useful to get an idea of the things you can do but only if your fitness knowledge is at an advanced level. The explanations are confusing, the suggested workouts assume you know certain things, there are exercises without images, or even not included just named. Another criticism is that even within the same chapter the exercises are named slightly different so it becomes again confusing.Over all it is not an easy book to use, it is badly edited and missing basic information when in others are overdone. In the end it is useless to have something complicated explained to such detail when the basics are not clear.Really it was quite a disappointment.
