Jogging is basically running at a steady (稳定的) speed over short or long distances. It became popular
some twenty years ago and has remained a favorite way of keeping fit for lots of people.
One of the main advantages of jogging over many other sports is that it can be done anywhere. People jog
in parks, in the country side and even in urban areas. No special equipment is required no costly hats, or balls,
and no expensive sports kit. Good quality running shoes are advisable. Special jogging suits are widely available
these days and can be bought quite cheaply but are not necessary. In addition to being able to jog anywhere,
you can also jog at any time, in any season! It's not unusual to see joggers exercising in the height of summer
or in the depth of winter!
The act of jogging doesn't require any special training or skill. You do need to be basically healthy and then,
after a few basic warm-up bends and stretches, you are ready to begin. You simply start running, gently, and
then build up to a steady speed. Do not overtire yourself by trying to go too fast. It is best for you to run at
a steady and comfortable speed.
Jogging is a single sport. You don't need to wait until you have gathered a team or found a partner. You
can jog alone. A few words of warning however: lone women joggers should be especially careful when
choosing jogging routes, particularly at night time.
Jogging is excellent for keeping fit. It's good for the lungs, the heart and the circulation. It's easy and
it's convenient. Why don't you try it? If you require more information, talk to one of the instructors at the
sports centre. We are only too happy to help. Please remember: if you do decide to jog, talk to your doctor
first if you have any health worries. Happy jogging!
