Overall an excellent book, has all you need to know. The book comes in chapters with chapter 1-3 talking about 'the genius of weights', 'all your lifting questions.. answered' and 'the world's greatest 4-week diet and exercise plan' - something I found very useful to dig a bit deeper into knowing about your fitness as well as improving your diet. Then with chapters 4-12 covering all elements of the body, giving pictures of each exercise so that you know how to do it correctly as well as step by step images/text as well as 'inspiration tips' if you will, which I found very encouraging. Finally, chapters 13-15 talk about 'the best workouts for everything', 'the best cardio workouts' and 'the big chapter of nutrition secrets'. This is also a key part of the book as here they create workout plans for you - making it easier focus on different parts of your body... it's like having your very own personal trainer at home!
The one negative to this would be that some of the exercises would require equipment available at gyms, but if you're doing it mainly at home then it may be difficult to do some of the exercises, but this all depends on the sort of equipment that you have at home. But apart from that, you could easily substitute some of the equipment so it's not a major problem.
