EXERCISE

Exercise will improve the tone of your muscles and blood vessels, changing them from weak and flabby tissue to strong and firm tissue, often reducing blood pressure in the process.

Exercise will improve your digestion by quickening the circulation and helping to lift the blood back to the heart from the digestive organs and thus normalizing your bowel action.

Exercise will increase the efficiency of your heart in several ways.  Gradually it will grow stronger and pump more blood with each stroke, thus reducing the number of strokes needed to supply your body with life-giving blood.
Exercise will increase the efficiency of your lungs, conditioning them to process more air with less effort.
