Five tips for safe running

We all know that exercise is good for our health. But some kinds of exercise may be better than others. Running, for example, may help to protect against heart disease and other health problems.

Running is good exercise, but it can be hard on the body.1.

Take it easy. Do not run too much, too soon or too fast. Most people get running injuries when they push themselves too hard. The body needs time to get used to increases in distance or speed. 2.

Listen to your body. Most running injuries do not come unexpectedly. 3. They may include body aches, sore muscles and pain that does not go away.

4. There is no single best shoe for every runner. You should find the shoe that offers the best fit and support for your feet. More importantly, you should replace your shoes every 500 to 800 kilometers.

Take good notes. Take time after each run to write down what you did and how you felt. Look for patterns(模式), things that happen over and over again. These notes will help you find the best exercise for you.

Cross train. As we said earlier, running is hard on your body. So physical fitness experts suggest some form of cross training to improve muscle balance and to help you stay injury free. They say swimming, yoga, and riding a bicycle are good exercises to combine with running. 5.

A. Get good running shoes.

B. Usually, there are warning signs.

C. Running may also help you live longer.

D. These exercises are easier on the body.

E. Muscles and joints(关节) need time to recover.

F. As advertisements for the running shoe Nike say, “just do it.”
