Male potency is subject to the natural aging process. This decline can be slowed down through regular training. Just like the endurance capacity of the cardiovascular system, potency also needs to be trained if one wants to maintain performance. With VigorRobic®, there is now a book available for the first time that focuses on the trainability of potency. In addition to introductory chapters that explain the structure of the male genitalia, the phases of erection, possible causes of their disruption, and the question of the trainability of potency, the book emphasizes training sessions aimed at improving erection stability, increasing blood flow, and enhancing oxygen supply to the penis.
