Ha ha. Finally someone likes me. Do you swing your hands from front to back or from back to front? Do you feel that there is always something in your shoulder joint? Sometimes there will be squeaking noise. This is the problem of long-term retraining. I used to be like this. But then the horizontal bar hung for a long time. You can hang it on the horizontal bar when you have time, and then turn your lower body or swing. As long as you hang on the horizontal bar for a long time (I feel much more comfortable after hanging for three weeks). ) basically OK after 2 months.
