Axillary is the place where lymph gathers. When there is constant pressure or you can't relax, it will lead to poor lymphatic circulation. If you want to keep the lymph unblocked, you must do more massage. Stand up straight when you massage. If you already have underarm fat, you can see concave and convex parts from the chest to the underarm when you stand. Knead the depressed part of the left chest repeatedly with the middle finger and thumb of the right hand. In the protruding part, make a fist with your left hand and push the protruding meat in your left chest inward with the strength of your knuckles. Massage the right chest in the same way.
