It is a common physiological phenomenon that the rectus abdominis muscle separates during the late stages of pregnancy and postpartum due to the increased tension in the abdominal wall caused by the enlarged uterus. In the postpartum period, the separated rectus abdominis muscle will be reset through training, which will play a role in fitness and body shaping. Abdominal rectus muscle rehabilitation training, usually we need to do the following: First, abdominal breathing, mainly diaphragmatic movement, with the abdominal movement, mainly exercise transversus abdominis muscle, from the internal contraction of the abdomen, the method is to take the supine or comfortable sitting position, unbuckle the belt relaxation of the whole body, will be the right hand on the abdomen around the umbilicus, the left hand to the chest, inhalation outwardly expanding the abdomen, exhalation inwardly contracting the abdomen, the maximum of the navel tie to the navel to the maximum. The maximum navel tied to the spine, slightly stop 5-10 seconds to do a cycle, pay attention to the whole process try to keep the chest immobile, we have to do abdominal exhalation, cycle to keep the rhythm of breathing consistent, usually do 5-10 minutes / times, do 3 times / day; second, transverse abdominal muscle exercise, from the internal contraction of the abdominal method of the following, lying on your back after the two legs bent at 90 degrees, the palms of the feet, the heels of the feet and the sitz bones at the same level, the whole body relaxation will put both hands on the navel, the left hand on the abdomen, the belly button and the left hand to the chest. Full body relaxation will be placed on both sides of the navel, inhalation outward expansion of the abdomen, exhalation inward contraction of the abdomen, while both hands down the trend of the inward lower push, efforts to close the gap between the rectus abdominis muscle, a slight pause of 5 seconds to do a cycle, that is, a cycle of 5-10 seconds, the cycle of the cycle of the same to maintain the rhythm of respiration, to do 5-10 minutes/times, that is, we do 3 times / day, do each time a minimum of 30-50 cycles. . Through the above training, together with our postpartum with the anus lift muscle training and sit-ups, it will soon return to its normal anatomical position.
