Dr. Jordan Metzl, "The Exercise Cure" | Talks At Google

As Dr. Jordan Metzl says, "Exercise is medicine." It's the simplest way to keep yourself healthy and happy. Now he puts that philosophy—along with cutting-edge research and a motivational bedside manner—into a groundbreaking book split into three sections. First, an AZ list of maladies that affect quality of life for millions, along with the specific exercise prescriptions that will help fix them—from Type 2 diabetes to depression, from arthritic joints to PMS, from addiction to sleep apnea (the book also includes a special section on how exercise can help cancer treatment). Second, a doctor-approved eating plan to fuel fast weight loss and great workouts. And most important of all, an exhaustive (and exhausting) collection of fun, fat-torching, life-changing workouts that can be tailored for any fitness level.

Dr. Metzl, a regular contributor to the Today show, is also a 9-time Ironman triathlete and 29-time marathoner. He's an inspiring guide as both a medical expert and an athlete who knows what it takes to work up a healthy sweat.
