how to get rid of a double chin

just like before any other workout, you’ll want to warm up your facial muscles.
For this purpose, move your lower jaw forward and backward and then side to side. All movements should be performed slowly and smoothly without sudden jerks. Repeat the exercise 8-10 times.

Open your mouth, and roll your bottom lip over your lower teeth. Imagine that you need to scoop water with your lower jaw. Move your head down in a scooping motion, and close your mouth while lifting your head.
While performing this exercise make sure that the corners of your lips are completely relaxed. Repeat 5-7 times.

A double chin is also associated with weakness of the hyoid muscles. That is why they also need to be strengthened.
Stick out your tongue as far as possible, and try to reach your nose with the tip of your tongue. Keep your lips relaxed. Repeat 5 times.

If you want to return the shape of your face to a younger look and pull your cheeks up, do the following exercise: turn your head to the left, and pull your lower jaw forward, straining the muscles of your neck. You should feel the muscles on the left of your neck stretching. Then turn your head to the right and do the same movement. Repeat 5 times on each side.
