How long you can exercise to lose weight after giving birth needs to be determined by the mode of delivery and the recovery of the mother after giving birth. In the second day after delivery, women who have given birth naturally can do appropriate exercises, such as walking slowly indoors and massaging the abdomen, not only to lose weight, but also to promote the recovery of the uterus. You need to gradually increase the amount and duration of exercise according to your physical condition, but pay attention to the amount of activity and the amplitude of exercise should not be too large, so as not to cause serious complications such as uterine prolapse. The woman who gave birth by caesarean section needs to extend the time of exercise and weight loss according to the degree of wound healing and body recovery, and can do proper exercise after the sixth week after delivery. But it should be noted that women in the puerperium should not carry out strenuous or high-intensity exercise, try to avoid long squatting, standing and other positions. It is recommended that women exercise to lose weight through deep breathing and abdominal contractions to reduce abdominal flab and at the same time promote the recovery of the uterus and vagina.
