Autumn is a good season to do sports because it is not too hot or too cold. But what you feel is quite different from what your body feels. Your body works more slowly, so it is easy for you to be hurt (受伤) when doing sports. Here is some advice (建议).
Drink water.
It is often very dry in autumn and your body loses water easily. So it is good to drink 500 ml of water two hours before you exercise. Or just do it about 15 minutes after exercising.
Warm up your body.
Before doing sports, you have to do some warm—up activities (热身活动), such as walking or morning exercises, to get your body ready for sports.
Have outdoor activities.
It is cool outside and the air is much better. So outdoor activities like climbing the hills, riding a bike, running and jogging are much fun. These can make you relaxed and help you work well.
Do not eat too much after sports.
It is very bad for your health if you eat too much after sports. You can have some fruit or vegetables if you really want to eat something.
