All of our physical features - from the shape of our waist and stomach, to the size of our wrists and the roundness of our arms - are based upon our personal genetics, fitness, and health history. So one person's body is different from another's. And that means that the exercise routine that works for one individual may not work for another. The key to fitness success is a customized workout. That's where Ben Greenfield's book comes in. Focusing on specific exercises designed to target individual body types, Ben provides all the tools, tips, and techniques to exercise the right way for each body type and achieve the dream body.
