Physical activity, physical exercise, and fitness are defined. Physical activity is any bodily movement that increases calorie use, while physical exercise is planned movement to improve fitness. Fitness includes health-related components like cardiorespiratory endurance and body composition, and skilled-related components like agility and coordination. Key terms are also defined, and the FITT principles - frequency, intensity, time, and type - for exercise prescription are outlined.
