WHY EXERCISE IS GOOD FOR YOU 

 

People who exercise are stronger and have greater endurance than people who do not. Exercise has other health benefits, too. Research has shown that exercise protects against coronary heart disease. 
Part of this protection comes from improvement in the heart's pumping action, a person who is physically fit pumps more bleed with each heart beat and is able to sustain demanding physical exertion at a lower heart rate than someone who is out of shape. 
Regular, moderate exercise improves your capacity for endurance, meaning you will be able to walk (or swim or bike) farther as you continue to work out. Exercise lowers the blood pressure a clear benefit since high blood pressure is associated with both heart disease and stroke. Exercise also burns up fat, controls weight, lowers your harmful cholesterol level, and raises your good cholesterol level (see fats and cholesterol coming pages0. Research has also shown that people who are physically active are less susceptible to the type of diabetes that develops in adulthood (type II diabetes).

 
Anyone who has been confined to bed for more than few days knows that his or her muscles and bones became weak. This occurs because minerals in the bones are excreted by the kidneys in large quantities during long periods of immobility. Exercise, however, builds up the strength of bones by stimulating bone building cells to create new bone. Research has shown that exercise at all ages improve bone strength. This is especially important for women after they reach menopause, when a lack of the hormones estrogen may lead to osteoporosis (thining and weakening of bone. (Exercise will help build up the bones to help protect against fractures in the future. 
Finally, exercise makes people feel good. people who exercise regularly feel healthy and are less likely to become depressed.
