Oral exercises can exercise the flexibility of our mouth and tongue. Essentials of oral exercises: Close your mouth, and then use your tongue to move up, down, left and right inside the mouth, first 10 times clockwise, and then 10 times counterclockwise. It's better to practice until your tongue feels a little tired.
Practice your lips. Close your mouth, and then exhale forcefully until your mouth is full, and then use the power of your lips to spit it out. This action can be a very effective way to practice your lips.
