Why Do We Have To Exercise?

WHY do we have to exercise?


1. Exercise makes you stronger and have greater endurance than people who don't do it.


2. Exercise protects you against coronary heart disease. Part of this protection comes from improvement in the heart's pumping action. A physically fit person pumps more blood with each heart beat and is able to sustain demanding physical exertion at a lower heart rate than a person who is out of shape.


3. Regular, moderate exercise improves your capacity for endurance. You will be able to walk or swim or bike farther as you continue to work out.


4. Exercise lowers the blood pressure. High blood pressure is associated with both heart disease and stroke.


5. Exercise burns up fat, controls weight, lowers harmful cholesterol level, raises good cholesterol level (below 200 milligrams/deciliter).


6. Exercise makes you less susceptible to the type of diabetes that develops in adulthood.


7. Exercise builds up strength of bones by stimulating bone-building cells to create new bone. If you sleep or are confined to bed for more than a few days, your muscles and bones become weak. It is because the minerals in the bones are excreted by the kidneys in large quantities during long periods of immobility.


8. Exercise at all ages improves bone strength. It is important for women after menopause, when a lack of the hormone estrogen may lead to osteoporosis (thinning and weakening of bone).


9. Exercise will help build up the bones to help protect against fractures in the future.


10. Exercise makes you feel good. If you exercise regularly, you will feel healthy and are less likely to become depressed.
