The heart beats faster during exercise in order to pump more oxygen-rich blood to the muscles and tissues that are working hard. As the muscles demand more oxygen and nutrients to support increased activity, the heart responds by increasing its rate and force of contraction to meet this demand. This helps to deliver the necessary oxygen and nutrients to the muscles, and also helps to remove waste products such as carbon dioxide. Additionally, the faster heart rate helps to increase the body's overall oxygen consumption and energy production during exercise. **
