It should be effective to insist on doing it often. I'll teach you a trick, thin belly, no medicine and no exercise.

Change the breathing mode from chest breathing to abdominal breathing.

The specific way is to lie in bed every night and inhale to inflate your stomach, and then exhale to abdomen. Breathe according to this rhythm, keep doing it, and it will be effective. This is what I learned in clinical training.

Thank you for your adoption!
