What should I do if my back is asymmetrical after a period of fitness?

This situation exists in many people. It has something to do with the habits of left and right hands. Do more training on the left side every time. For example, rowing with dumbbells on one arm. Usually use your left hand. In addition, when the last few movements are particularly tired, the body will exert its strength unconsciously, so it is necessary to pay special attention to the fact that the last consciousness must be that the left side participates more.
