My shoulders have no sense of lines. What behaviors can be corrected?

0 1 1. Shoulder exercise tips 1. Don't tighten our shoulder blades when practicing shoulders. It is best to look at the ceiling one by one, so that the effect will be better than in front of you. 2. Shoulder training should be carried out step by step, and auxiliary training should not be carried out in large units at the beginning, and shoulders can't bear it. Train from small to large, step by step, anything will do. The number of exercises is much more useful than the number of times you carry loads. We can practice the same movement several times instead of focusing on the object you are carrying. We can practice each movement several times within our tolerance, and the effect will exceed your imagination.
