Since the reform and opening up, China's economy has developed rapidly. At the same time, people's living standards have been greatly improved. In the past, people thought about how to support their families every day. Now people are more concerned about how to relax and enjoy life while working. With the progress of people's ideas, people's awareness of physical exercise is getting stronger and stronger. The most obvious is the development of fitness industry in China in recent years, and gyms can be seen everywhere. When it comes to physical exercise, people usually choose to go to the treadmill in the gym, and sometimes we also go running.

1. Too fast

Many people are eager to succeed in sports. Some people exercise to lose weight, so they often speed up when running, because they think it will make them lose more meat faster. So they may unconsciously increase their speed when running, but this speed is not suitable. So sometimes when they run, their chest hurts because they are running too fast.

2. Low vital capacity

Many people don't pay much attention to vital capacity, but in fact, vital capacity is also a factor that affects their running speed or the intensity of exercise that the body can bear. So this is also one of the reasons for the dull pain in the chest when running.

3. Underwear is wrong

Sometimes some women feel dull pain in the chest because they wear the wrong underwear when running, which affects the chest and makes the chest feel great discomfort. Therefore, at this time, it is better to change a kind of underwear, such as a sports bra, to see if your situation has improved.
