Written by a woman who began running marathons at 50 years old, this inspirational guide describes the physical, mental, and emotional benefits of exercise. It confronts the problem of obesity today—nearly 60 percent of Americans are overweight—and emphasizes that weight control becomes an even greater challenge with age. But as this handbook asserts, it’s never too late to get fit. In nine easy-to-follow steps, the mechanics of an exercise program are clearly explained to help fitness first-timers devise their own regimens and become healthier in all areas of life.
