Many people actually have lumbar problems before fitness, which is a matter of a person's comprehensive posture and exercise habits, so these people must be more careful when doing any fitness exercise, and don't make their injuries worse or even cause themselves some physical accidents because of these actions.
Don't do the so-called comic waist action.
The action of comic waist was originally brought out by some stars, because these stars thought the action of comic waist was particularly beautiful, so they posted it on the Internet, and many people would imitate it, but when these people imitated it, the doctor suggested not to do it, because it would lead to a person's lumbar hyperextension.
This action is not good for the lumbar spine.
We can imagine that when a person is lying on the ground, if the lumbar spine is excessively twisted, it is likely to lead to lumbar hyperextension, which is a very serious posture problem. Normal people should try to avoid this situation, because this situation will lead to a person's lumbar spine substantial lesions. If a person's lumbar spine really has a problem, it is likely to produce some irreparable costs. So for most people, don't try the so-called comic waist action easily, which will bring you great security risks.
You must fully stretch and study before exercising.
Many people may not have the habit of exercising before, so they will directly put their enthusiasm into sports. I don't know that such behavior will bring great danger to myself, and many people will be injured in the process of sports. Therefore, I think if a person really wants to exercise, he should fully stretch before exercising, but in fact, he should study more in private. Only when he has enough knowledge of sports can he make sports serve his health.
