I am a fitness instructor. In the process of losing weight, I will lose weight and the excess fat in my body will be consumed. Now after abdominal fat consumption, the skin of abdominal wall will relax. It is suggested that you need to do abdominal exercises to restore the elasticity of your skin, do sit-ups and other exercises, stick to it for a long time, and be careful not to eat too greasy food in your diet. You can consult me if you have any questions.
