Detailed explanation-1: -Your heart is a muscle. Just like your bicep, the more you work your heart, the bigger and stronger it gets. During moderate-to high-intensity exercise, your muscles and tissues demand more nutrients and oxygen, which means that your heart must work harder and pump faster to meet those needs, says Dr. Cho.
Detailed explanation-2: -Exercise improves myocardial perfusion and increases high-density lipoprotein (HDL) cholesterol levels, all of which reduce stress on the heart and improve cardiovascular function in healthy and diseased individuals (11, 15, 29, 30).
Detailed explanation-3: -During exercise, more blood is sent to the active skeletal muscles, and, as body temperature increases, more blood is sent to the skin. This process is accomplished both by the increase in cardiac output and by the redistribution of blood flow away from areas of low demand, such as the splanch-nic organs.
