For men, exercise has a wonderful advantage: it can enhance sexual ability. This study selected nearly 600 men as the research object, which lasted for 9 years. All 600 subjects had no sexual dysfunction at first. Then, Dr. Gordon Stein followed the lifestyle of these people, and focused on some factors that were traditionally associated with impotence, such as smoking, drinking, inactivity and being overweight. It is found that men who have exercise habits are less likely to suffer from impotence. Exercise can avoid cardiovascular disease and impotence, which is actually based on the same principle, and it is related to whether there is enough blood flowing to the needed organs, and exercise can keep the blood vessels unblocked. In fact, impotence can be regarded as an early warning signal of cardiovascular diseases, because when the blood in the body is not smooth, the response of penile erection is more obvious. After many middle-aged men enter middle age, their work and family are very stable, they are easy to indulge in comfort and gradually lose interest in sports; Or think that only people with headache, fever, backache and leg pain need exercise. But I don't know whether regular exercise is closely related to the strength of sexual ability. Regular exercise can not only reduce the chance of impotence, but also help to strengthen yang. Such as playing ball, walking, swimming, fitness and so on. Everything is fine, but the only wrong exercise is cycling, which will increase the chance of impotence.
