Exercise for Health and Wellbeing
Physical fitness is a measure of the condition of the body to perform during activities of daily living (light, moderate, and strenuous), formal exercise (like when you work out), and emergencies (as when you must escape from danger like a fire).
The physical fitness of our nation is declining, proved by the rising rates of obesity, diabetes, some types of cardiovascular disease, and other medical conditions. To improve physical fitness, one must "practice," or work out. Emphasis should be on improving aerobic conditioning (stamina or endurance), muscular strength and endurance, and flexibility.
