What is exercise? The actual definition of exercise is; to use repeatedly in order to strengthen or develop, but to make it simpler, exercise is doing programs and workouts to keep fit, for example, running, hiking, bicycling, and any active sport. .
Most Americans do little or no exercise during work or rest hours. Today there aren't many jobs requiring intense physical activity. Instead of walking, people use automobiles or public transportation. Instead of being physically active, people usually watch TV in their free time. Some sports such as bowling, golf, and tennis (doubles) provide some exercise, but do not provide as much exercise as other more vigorous sports. .
Exercise is very important and is beneficial both physically and mentally. When you exercise, you feel better about yourself because you are fit or your getting fit and you feel that you have accomplished something that was hard to strive for. The benefits of physical activity is it gives you more energy, it helps you in coping with stress, it improves self-image, and it increases resistance of tiredness. .
Exercise does not only keep you fit, it also reduces your chance of heart attack. Various studies have shown that the chance of heart attack is two times more likely to happen to an inactive person than a more active person. It really all adds up because with exercising, you burn off calories, which keeps you at your desirable weight, which lowers your risk of heart disease. .
There are risks in exercising though. The major risk in exercising is injury to the muscle or joints. This happens when a person exercises too hard for too long, this mostly happens to people that have been inactive for a while. .
In some situations, people have died while exercising. In these situations, most of the deaths have been by overexertion in people who have had heart problems. For people who are under the age of thirty, these heart conditions are usually from heart defect present at birth.
