When excersise backfires
Every person needs to perform some kind of physical excersise regularly in order to be healthy. Gymnastics and other physical activity do not only improve our phisical capabilities such as strenght and speed, or even the appearance of our bodies. They make us healthy by activating our organism and strenghtening it from the inside. Aerobic excersise such as running, swimming and cycling increase the blood supply to all areas of our body and help us fight the negative consequences of sedentarism such as overweight and chronical conditions.
You do not need to be an athlete or an olympic gymnast in order to be healthy. You just have to perform some sort of physical excersise regularly. Your body is like an engine: if you don't put it to work every once in a while, someday you find out that it just doesn't start anymore. And you need your body to be alive, so you better take care of it by excersising it regularly.
