Good exercise for the heart is aerobic exercise, such as walking, swimming, cycling and so on. 1. Walking: Walking has the effect of exercising the heart and lungs, improving heart contractility and heart loading capacity. Walking can help control blood lipids, improve fatty liver, control weight and reduce the risk of heart disease. 2. Swimming: regular swimming can make the body’s blood pressure, blood fat, blood sugar lower, so that the heart muscle contraction force increased, a greater degree of blood supply to the heart, but also exercise cardiopulmonary capacity to increase lung capacity. 3. Cycling: cycling can prevent blood vessel refinement and heart aging, cycling can improve myocardial function, thereby strengthening the heart and microvascular tissue. Long-term adherence to aerobic exercise can enhance cardiopulmonary function and reduce the incidence of cardiovascular and cerebrovascular diseases. Exercise should be in moderation, and if discomfort occurs, you should go to the hospital in time.
