My specific practice is to lie in bed every night before going to bed, drop 4 drops of olive oil on my lower abdomen, and then massage my hands clockwise around my navel for 50 times (counterclockwise should be equally effective). Generally, if you massage your right hand for more than 20 times, you will be tired. Then you can massage it with your left hand for more than 20 times, just 50 times, and then massage the remaining olive oil to the skin under the ribs, which is neither wasteful nor moisturizing the waist skin.
