If your elbow is floating you will become a stiff shoulder

Do you know that you are getting stiff when your elbow is floating?


What is an elbow floating? I think that there are also many people who think.
For example, when operating a computer with desk work, since there is no support for the arm that extends to the computer, it is floating in the air.
Also, when you are operating a smartphone, you are doing your arms floating in the air.
Thus, for example, there are many people who think that "there is a certain !!".


So why does the elbow float and the shoulders come over?
That's because the muscles tense and lifting the shoulder blades keeps the elbows floating.


One arm is said to weigh one cabbage.
It means that the muscle has lifted this weight for a long time via the shoulder blades.
Therefore, it becomes a stiff shoulder.


Take a break frequently during desk work and try light prevention such as prevention of arms out!
