Male potency is subject to the natural aging process. This process can be slowed down by regular exercise. Just like the endurance ability of the cardiovascular system can be exercised, potency has to be exercised as well if the man wants to sustain his performance ability. VigorRobic® is the first book ever that deals with exercising potency. In addition to articles of introduction that explain the structure of the male genital organ, the phases of erection, possible causes of their disturbances as well as the question about the trainability of potency, training sessions for the "steadiness" of the erection, to increase the blood flow and for the oxygen supply of the penis build the focal point of this book.
