Impairment of physical exercise

Although a priori physical exercise as a positive and healthy, we must consider how much exercise is safe for health and what exercise you should practice. A widespread perception is quite wrong that the practice of physical exercise, which sometimes seems to follow implicitly from the benefits proclaimed grassroots health, is that these positive effects occur only by their practice without explaining precisely what should be the content, volume and intensity of the practice, according to the characteristics and circumstances of the individual, which are factors that must be concretized in a prescription.
