     Every day, in all kinds of weather, many thousands of men and women jog. Why has jogging-running

slowly for long distances become so popular? Most joggers begin because they hear it is a very good exercise.

Jogging makes the heart stronger and helps people lose weight. It can also help them feel better about

themselves.

     Donald Robbins, who is forty-two years old and works in an office, began jogging a few years ago

because he felt he was too fat. At first he could only run about 100 yards. It took him three months to be

able to run a mile. But two years later, he ran in a marathon race over twenty-six miles. Many joggers, like

Donald Robbins, feel that if they can succeed at jogging, they can succeed at other things also, and quite often

this feeling helps them at their jobs.

     Should you jog too? If you do, be sure to ask your doctor for advice. Jogging may be too much exercise

for you.

     Does jogging cost much? No, it costs almost nothing. But it is very important to have a good pair of shoes

that are made especially for jogging. They protect your feet and legs from the shock of running on hard

surface.

     How fast should you go? Jog with a friend and talk to each other as you run. If you have difficulty in

talking, you're going too fast.

     How far should you jog? Remember not to go too far too soon. In fact, you should walk, not run, the first

few times. Then do some short jogs, but no more than what you can do comfortably. After that, increase your

distance a quarter or half mile every two weeks or so. Maybe in a few years, you can run in a marathon too, as

thousands of people do.
