Details pursued by experts. Of all the fitness techniques. One word we often hear is "shoulder sinking", so do all fitness movements need shoulder sinking?

If the shoulder sink is insufficient, the deltoid muscle will be involved too much. Chest muscles are difficult to use. On the contrary, when you sink your shoulders, you will unconsciously feel that your chest muscles are pulled out and tightened. Can exert great power.

Without heavy shoulders, the scapula is not fully activated. The latissimus dorsi can't do it, it's all about the arm, which loses the meaning of using pull-ups to practice the back. Therefore, shoulder sinking is the key to pull-ups

A coherent pull-up should look like this.

I'm talking about shoulder push here, whether standing or sitting. Many people think that after the dumbbell is launched, you should keep your shoulders sinking.

But in fact, this will make the space in our shoulder joint very small, and it is easy to hurt our shoulder joint.

So you might as well shrug your shoulders at the highest point of the action. Give more space to the shoulder joint to avoid joint injury. As for many people, shrugging can lead to trapezius muscle compensation.

Don't worry, pushing shoulders is very useful, and shrugging only happens at the peak. In the previous process, they all sank their shoulders, which has made deltoid muscles participate well. So it will not affect the exercise effect.
