Good afternoon, folks! Today's topic is try jogging for fitness. When we run for fitness, exercise and pleasure, it is commonly called jogging. Jogging has become very popular in recent years. The popularity of jogging today stems from several factors. First, jogging is one of the most efficient forms of exercise. As a rule, a person jogging burns up more calories per minute than in most other sports. Running, like biking, swimming, and brisk walking, is an aerobic exercise. Such an exercise uses a great deal of oxygen. In addition, it increases the heart rate. Aerobic exercise strengthens the heart muscle so that it pumps more efficiently. This kind of exercise is also one of the best ways to improve our general health and capacity of our lungs. Jogging is also popular because almost every oneof us can take part. Jogging is an activity that doesn't require any unusual skills or special coordination. Jogging is relaxing and fun. Finally, it can be done alone, with another person or in a group. For anyone who runs more than 20 miles a week, it is important to have good running shoes. Tennis shoes or sneakers won't do. Running produces stress that is three times greater than the stress of walking. With this added stress to our feet and legs, we need good shoes. The shoes should be replaced when they are worn out or worn unevenly. Cold weather poses a few problems for us joggers. The main hazard in winter-running is slipping on ice or snow. There is no danger of freezing our lungs, because our body warms the air before it reaches our lungs. In winter, we should be sure to cover the head and keep our feet as dry and warm as possible. It's best to wear layers of clothing. In summer, we must be careful not to dry out. So it is important for us to drink plenty of water on hot, humid days. The best summer wear is loose-fitting and light-colored.
