How long will it take me to reach a healthy weight goal starting from my present weight? Realistically, how long will it take me to improve my strength or muscle mass, reduce my waistline, or get competitive for sports? This book delves into a biological principle that explains why it takes time to change in the ways we desire. But it also puts a free tool in your hands for charting your own data in a way that lets you track changes and figure how far you are from a plateau and how long it will take to get there. Highly recommended for people who want to make a serious change in their lives, and for personal trainers, dietitians, and counselors who help guide people in their quests for better fitness and health.
