Answer:
The reason is because the heart requires more oxygen when exercising. Several physiological events happen to increase the blood flow and therefore oxygen flow to that muscles,including the heart.
Also the volume of blood that the heart pumps out is maintained so that the body organs receive the necessary amount of oxygen and nutrition, because if it didn't adjust the flow of blood to match activity level, you will be insufficient. Either output method will be lower than needed.
<u>Just a few tips would include:</u>
-Set reasonable goals
-Stay dedicated
-Divide your goals up and conquer a little bit at a time until you accomplish it
-Find somebody that can keep you accountable
-Plan for setbacks and how to handle them
-Think of some things needed to get there
