Experts remind that although you exercise indoors, you should also pay attention to the following four points: 1. Evaluate the air quality of indoor sports venues. Generally speaking, venues with air purifiers are more suitable for sports. Don't blindly think that as long as they are indoors, they will not be affected by smog. 2. Have a clear understanding of your physical condition, choose the exercise that really suits you and exercise moderately. 3. Choose the appropriate exercise time, and don't exercise after meals or drinking. 4. Warm up before swimming and other sports to avoid danger.
