The method of chest massage: press the palm of your right hand on the top of the right breast, with your fingers obliquely downward, and moderately push it to the left lower abdomen, and then use your left hand to obliquely push it to the right lower abdomen from the top of the left breast, so that the left and right hands alternately cross, up and down once, and massage for dozens of times continuously. If you can take a deep breath after each chest massage, it will help to get rid of the old and welcome the new, and the fitness effect will be better.
