Very detailed and very passionate discussion of why it's better to do resistance exercises with your body rather than with weights (such as barbells, dumbbells, or machines). Lots of detail on the physiology and physics behind exercising, and lots of useful discussion of different types of exercises (with many variations).
I suspect this book works better in print. I did not care for the layout, which made it hard to work through. I also think a book like this would be ideal in electronic format, and I would have loved to see video demonstrations of the exercises. Put differently, this is a Kindle adaptation of a paper book; however, the subject-matter is far more suitable for an electronic treatment, with video, audio, etc.
I will admit in this review that I did not read the book carefully; rather, I read it with an eye towards rethinking my workout regimen. Currently I focus on using freeweights, although I have given myself a number of minor injuries (knee, elbow). I suspect that Gaddour is totally right that I should switch from freeweights to body resistance (as well as band work). So this is a resource I plan on returning to as I revise and improve my regimen.
