Generally speaking, if the review is normal 42 days after normal delivery or 3 months after cesarean delivery, you can resume running appropriately, which varies from person to person. In case of normal delivery, you need to go to the hospital for a review 42 days after delivery, mainly to understand the recovery of the uterus and the recovery of the pelvic floor muscles. If the uterus recovers well, there is no malignant dew, there is no symptom of pelvic floor muscle relaxation, and there is no sign of stress urinary incontinence or pelvic organ prolapse, then you can gradually resume running exercise. In case of cesarean section, running is usually not recommended within 3 months after the operation, and a review should be conducted 3 months after the operation, and if the recovery is normal, running can be resumed. Before resuming running exercise after delivery, you need to prepare for the exercise and choose comfortable and special running shoes. Running exercise must be gradual, gradually enhance, not at the beginning of the strenuous running. If there is any discomfort during the exercise, it should be stopped in time.
