Most people would agree that exercise is good for the heart. With the right type of exercise, the heart pumps more blood and becomes more efficient. During relaxation, the heart fills with blood. When the heart pumps, the blood is expelled to the body.Exercise increases muscle contraction, and this pushes blood toward the heart. The heart rate will increase at this time. A fast heart rate without exercise is of no benefit. This results from emotional responses. The heart gets strong from exercise by pushing against larger volumes of blood. The heart is a muscle, and can atrophy from lack of exercise. Exercising for 20 minutes, 3 times per week, can be of great benefit. Always consult a physician before starting an exercise program.
