Biller integrates research about exercise, nutrition, and health within an applied developmental psychological framework. Readers are presented with ways of making fitness an enjoyable and positive force in their daily lives. Although a major focus is on how to get in shape, Biller's primary mission is to encourage a healthy lifestyle that enriches self-awareness and personal growth. The goal is not just to facilitate physical fitness, but to enhance overall life satisfaction. The book's uniqueness, accordingly, lies in its ability ot help individuals develop a creative, playful approach to fitness in all spheres of their lives. While some readers are just beginning to think about fitness because of a desire to lose weight and improve their appearance, others are more interested in refining their athletic skills or achieving a greater balance in their daily activities. Dedicated exercisers often are striving for new routines and ways to prevent "burnout." Many parents, moreover, are searching for activities to help their children, as well as themselves, become more fit. Older individuals are especially likely to be concerned about staying healthy and avoiding physical dependence as they age. Biller speaks to all these concerns--and all these groups--by providing an approach to getting in shape that enriches self understanding and mental vitality.
