Many people need to warm up before fitness or at the beginning of some aerobic exercises, which is also very correct. Think about it. In the past, when we went to school and went to physical education class, our teachers always gave us such advice. The reason for doing this is to open all the joints of our body. Because we don't exercise for a long time, if the joints suddenly move in general, it will cause strain.

Therefore, proper warm-up exercise can advance all joints of the body without causing this kind of muscle strain. For us adults, don't do such strenuous exercise suddenly. For example, I got off work some time ago and wanted to walk home on a whim.

In fact, the unit is not far from where I live, especially after climbing a hill in a park, I can get home in 20 minutes, so in order to test my endurance, I ran from the foot of the mountain to the top of the mountain in one breath, and I didn't feel any adverse reactions at that time, so I couldn't even get out of bed the next day.

First of all, the calf muscles are particularly painful, and the chest also feels coughing with pain, which is a serious consequence caused by muscle strain. Because of this, I didn't dare to do much exercise after resting at home for a week.

So before you do anything, you still have to do what you can. Nowadays, most young people lack exercise and are weak, so I also suggest that when you have time, you'd better exercise more. Even giving yourself half an hour to go out for running every day is very good, which can enhance your physique and enhance your immunity.
