Stop training your abs. Are you training your abs in the hope that you will be able to see them? It doesn’t work like that. The abs are a muscle – if you train them, they will grow under a layer of fat, and your waist will get wider. Everyone has “sixpack” from birth, you need to correct your diet – burn fat and you will be able to see it.
Don’t eat all your food at once. The point is not to divide it into 6 or 8 meals. But learn to eat 3 times a day.
Vacuum! Magic exercise! Once a day, 5 minutes. And your waist will become noticeably narrower in the first few weeks.
