Physical exercise is any bodily activity that enhances or maintains physical fitness and overall health. It is performed for many different reasons. These include: strengthening muscles and the cardiovascular system, honing athletic skills,
and weight loss or maintenance. Frequent and regular physical exercise boosts the immune system, and helps prevent diseases of affluence such as heart disease, cardiovascular disease, Type 2 diabetes and obesity. It also improves mental health and helps
prevent depression. Childhood obesity is a growing global concern and physical exercise may help decrease the effects of childhood obesity in developed countries. Physical fitness is the functioning of the heart, blood vessels, lungs, and muscles at
optimum efficiency. In previous years, fitness was defined as the capacity to carry out the day’s activities without undue fatigue. Automation increased leisure time, and changes in lifestyles following the industrial revolution meant this criterion was
no longer sufficient. Optimum efficiency is the key. Physical fitness is now defined as the body’s ability to function efficiently and effectively in work and leisure activities, to be healthy, to resist hypokinetic diseases, and to meet emergency
situations. Fitness can also be divided into five categories: aerobic fitness, muscular strength, muscular endurance, flexibility, and body composition.
