My favourite sport is running. Every day I always spend half an hour on it. Sometimes I will intive my parents or my friends to join me， and I am really enjoy this sport .
Doing exercises is very important for everyone. If you want to do some things good， you must have a atheletic build， and then you can pay all your attention to your work or study with a good health.Running is a good way to keep fit. First， it can make your bonds flexible and keep far away from illness and kinds of pains. Secondly， running can make you become not lazy， and you can go outside， breathe the flesh air， and have an active body and a good mood.
So， please do some sports to keep you in a good health.
