Standard standing posture
When standing, some people bend over or fork their legs into compasses for comfort. This kind of standing makes you relax for a while, but in the long run, the spine and lumbar spine are easily stressed, which leads to lumbar pain.
The standard standing posture pays attention to one line and two cores, that is, the back of the head, back, buttocks and heels are in a straight line, and the waist and abdomen are two cores. People stick to the wall, at the same time, their muscles are tight, their shoulders are abduction, and their legs are slightly hard. If you find it a little difficult to stand like this, you can find a wall and stick to it for two stops, which makes it easier to stick to it.
