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.
Simplistically, it is believed that the more exercise is performed the greater the benefits in health and body image. Have been created so wrong about topics such as sport.
Health and slenderness

Overtraining, the sharp pressure from the media and advertising in ideal physical appearance, not only reflected in eating disorders in women, such as bulimia and anorexia, but is also affecting men through a variety disorder called EDNOS (eating disorder not specified).

Generally, to obtain appropriate adaptive responses to exercise in adults it should be noted that minimal stimuli do not produce adaptation, intermediate provide optimal and maximum responses can lead to dangerous situations. The planning exercise should be conducted every respect, but giving preference to the development of resistance, flexibility, coordination and muscle conditioning. It may be desirable to enhance a muscle group deficit at the start of aerobic conditioning. Not adequately rehabilitate the muscles needed can lead to recurrent injury and abandonment of fitness programs. When the individual takes time without doing a sport or have not ever done, caution will be taken at the beginning of conditioning, stress intensities recommending soft, about 3-4 METs, with slight increases every 3 to 4 weeks. Supervision by a trained professional is necessary in this group. Whether the recommendations are made by technical staff to individuals considered in isolation, as if done from public health services through campaigns or health education programs, it is necessary to clearly define the objectives to be achieved, the type of and recommended exercise intensity, frequency and duration. The program always well advised to age, sex, health status, constitution, physical and personal interest.
