5-Factor Fitness is a revolutionary plan that actually encourages you to work out less and eat more. That's right, sweat less and never go hungry. If you don't believe it works, just take a look at Pasternak's client list, including some of Hollywood's most beautiful bodies.

His program is based on the simple premise that less is more, especially when it comes to exercise and planning meals. There is no magic, no hidden secret. Instead, this plan taps solid scientific research as well as the author's vast experience as a personal trainer and as a consultant to military organizations on two continents. With a master's degree in exercise physiology and nutritional science as well as an honors degree in kinesiology, Pasternak is an expert on how the body works.
