Regular physical activity provides numerous health benefits, includ-ing a reduced risk of diabetes, osteoporosis, obesity, some cancers, and heart disease, as well as increased mental well-being, longevity, and life satisfaction. Beginning a physical fitness program is important at any age, and it can provide a lifelong love of fitness in children, increased strength and endurance in adults, and improved balance and flex-ibility in the elderly. Yet, according to the Centers for Disease Control and Prevention, almost 39% of Americans engage in no leisure-time physical activity.
