The book approaches fitness from a Paleo lifestyle standpoint and being fit as a means of preventing injury during physical exertion, maintaining wellness, and achieving longevity, all with a dash of humor. This is a very interesting and inspiring book. As much attention is placed on the workout as on the mindset. The workout program is focused on staying consistent and gaining power and strength, among other things. In other words, weight is placed on function rather than appearance. The author discusses exercise tools, techniques, goals, frequency, and exercise duration. The book is great for beginners, the athletically challenged, and athletes alike.
