I did some push-ups and arm exercises (regular exercise) at night, and there was nothing uncomfortable after exercise, but I slept until midnight at night, and my chest muscles on both sides were extremely painful. ... There are two possibilities. One is that you don't pay attention to breathing when you exercise, so that your chest muscles (outside) are in an anaerobic state, producing a lot of lactic acid, which will temporarily make your muscles ache! The second is that you accidentally pulled a muscle when using the arm strength device! In view of the above situation, you can stop exercising for two days and rub medicine. If the symptoms are relieved, it belongs to the first type! Then don't worry, lactic acid will fade automatically! If it still hurts after two days, see a doctor quickly! The above opinions are for reference only! Hope to adopt.
