One of the easiest ways to keep healthy is to do jogging. “ Jogging is the name for a very gentle （温和的）running ——it is just a little faster than walking.”
Start slow jog 20 meters, then walk 20 meters. Little by little, if you are not feeling very tired, you may do more jogging and less walking. Finally, jog the whole day. It will be easy for you to start jogging for 15 minutes twice a week. Then increase(增加) this to 20-30 minutes every day. The longer you join in jogging, the more you enjoy it and the healthier you will become. Some people like jogging alone (独自地) , and others enjoy doing it with friends. Jogging in groups makes more people keener (热心的), because you can not stay in bed while there is a group of friends waiting outside.
If you want to start jogging, prepare a pair of comfortable shoes and determined (坚定的) mind.
