My favorite physical exercise is jogging. It is perhaps the most popular and healthy way of keeping fit for people. It is basically running at a steady speed over a certain distance. It is a form of exercise which can be enjoyed by men and women of any age. One of the main advantages of jogging is that it can be done anywhere. People jog around college campuses,in parks and even on city streets. No special courts or running tracks are necessary. Similarly, no special equipment is required. What I need is just a pair of good quality running shoes and loose comfortable clothing. In addition to being able to jog around anywhere, I can also jog at any time. I usually jog in the morning. There is a saying that one day's planning is in the morning. When I go jogging around the campus' the fresh morning air makes me feel energetic. After jogging I feel in a good mood and can concentrate on my study. Since jogging is a solo sport, I don't need to wait until I have found a partner or gathered a team. I can jog alone. Still another good thing about jogging is that it doesn't require any special training or skill. I can start after a few basic warm up bends and stretches. It is easy and convenient. It is good for my lungs and heart.
