Detailed explanation-1: -Exercise has also been found to have beneficial effects on the heart. Acutely, exercise increases cardiac output and blood pressure, but individuals adapted to exercise show lower resting heart rate and cardiac hypertrophy.
Detailed explanation-2: -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.
Detailed explanation-3: -The muscular walls of the heart increase in thickness, particularly in the left ventricle, providing a more powerful contraction. The left ventricles internal dimensions increase as a result of increased ventricular filling.
Detailed explanation-4: -Being physically active is a major step toward good heart health. It’s one of your most effective tools for strengthening the heart muscle, keeping your weight under control and warding off the artery damage from high cholesterol, high blood sugar and high blood pressure that can lead to heart attack or stroke.
