Start by curling your lower lip inward and position it over your bottom teeth. Open your mouth wide and then move your jaw up and down. Keep on doing this motion for as long as you can tolerate and then relax.

Do some chin slap by continuously tapping your chin with the dorsal part of your hand (the back part of the hand opposite to the palm). Repeat this motion for as long as you can tolerate and do this procedure for as often as you can remember.

Chew some gum. This can be of good help to trim up your double chin.

Begin by sitting upright with mouth closed. Turn your head up to look at the ceiling, and then elevate your lower lip over your upper lip as far as you can, until you feel a contraction on your chin area. Hold this position for 5 to 8 seconds and relax. Repeat this procedure five times.
