This is a very fun and informative book to read if you're considering a career as a personal trainer. I've been in the industry for quite a while and still found it a worthwhile read. The actual experiences of different personal trainers portrayed in this book was probably my favorite part, but there was really not one chapter in this book that I didn't feel I benefited from reading. If you are new to the personal training industry or are considering fitness as a career, this is a great book to start with.
One aspect of training this book does not cover, which is fine because that's not what this book is for; is the selling side of personal training. That's right, your new personal training position has very much to do with sales. I still remember having to sell my first client personal training sessions, I had no idea what I was doing nor that I was doing sales when I signed up to be a trainer. It's not that bad once you get the hang of it, just remember that helping people is the name of the game. I would suggest looking into some type of book that teaches you how to sell, makes things much less stressful. Here are two good books on the subject:
1) The Personal Training Sales Education Textbook: A simple and effective sales system designed specifically for the personal trainer in the health club.
2) Selling Personal Training : How To Make the Most of Your Personal Training Business
