One of the easiest ways to keep fit is to do jogging. Jogging is the name for very gentle running—it is just a little faster than walking.
Jog 20 meters,then walk 20 meters. Little by little,if you are not feeling very tired,and slowly increase this to 20——30 minutes every day. The longer you join in jogging,the more you enjoy it and the healthier you will become.
If you want to start jogging,you should prepare some comfortable sports clothes and good running shoes.
