学读VOA：Exercise and Health (3) - 恳请指正

BOB DOUGHTY: Exercise improves your energy levels by increasing the flow of blood to the heart and blood vessels. One of the main reasons people exercise is to control or reduce their weight. Physical activity burns calories – the energy stored in food. The more calories you burn, the easier it is to control or reduce your weight.

So exactly how much exercise do you need to do to gain all of these great health effects? Experts say it is easier than you think.

In two thousand eight, the Centers for Disease Control released its first ever Physical Activity Guidelines for Americans. The report included suggestions for young people, adults, disabled persons and those with long-term health problems. One of the major ideas noted in the report was that some activity is better than none. So if you are not doing anything, now is the time to get started.
