My point of view about doing sport: is really so healthy as show us? Nowadays, there is a growing in the number of persons that practice sport, but I have a question. People are ready to do sport? After a lot of years without practice any kind of sports, they decide to buy new clothes, buttoning up their new sneakers and go out to "running", but the most of them ¿are really ready to running? I´m my opinion, first of all should consist in go to a medical center and check up your body, your circulatory system, your pulmunar capacity, your nutrition habits, before of this, speak with a profesional trainer, not personal trainer ( some of them could be only "gurus" and not be really prepared for this, they should have a good formation due to are working with the healthy of the people. I´ll follow with this matter considering that I think is important. My best regards!
