Two years after the birth of a baby the belly is still very large, there are two common reasons for this situation: the first reason is obesity, obesity requires weight loss treatment, that is, control your mouth and open your legs. The second cause of a large belly is the separation of the rectus abdominis muscle. During pregnancy, the growing uterus will pull the abdominal muscles apart laterally, and if the separation is not serious, most postpartum mothers can repair it on their own. However, if the separation is more than three centimeters and there is no active and appropriate exercise to repair the separated rectus abdominis muscle after delivery, it will lead to the persistence of the separation of the rectus abdominis muscle, which will manifest as a large belly. The preferred option for the separation of the rectus abdominis muscle is non-surgical treatment, which allows the separation of the rectus abdominis muscle to recover through exercises that enhance the ability of the abdominal muscle groups and restore the elasticity of the abdominal muscles. However, you should not do curls and sit-ups without recovering the separation of the rectus abdominis, as this will aggravate the separation of the rectus abdominis. It is best to practice under the guidance of a fitness instructor or yoga teacher. If, after training, the separation of the rectus abdominis muscle is still large, it can be corrected by plastic surgery of the abdominal wall if necessary.
