Generally speaking, it takes about 2-3 months of recovery time after a normal delivery before you can gradually start running. Before starting running exercise, the mother should complete the pelvic floor muscle strength screening, if there is no pelvic floor muscle laxity, then running exercise can be carried out. The exact duration of running exercise after normal delivery is governed by the individual’s recovery. Usually, the puerperal period lasts 6-8 weeks after a normal delivery. During this period, the mother has not yet recovered from the injuries caused by the delivery, so she needs to rest and recuperate, so that her organs, especially the reproductive organs, can recover gradually. If the mother has recovered well after the puerperium and her body functions and reproductive organs have been restored, she can start running and other sports and exercises in a gradual manner in about 2 months. If the mother’s body has not recovered well after a normal delivery, and there are problems such as persistent discharge and gynecological inflammation and infection, the recovery time will be extended accordingly, and it may take about 3 months for the body functions to recover gradually, so she should wait until her body has recovered before she starts to think about running and other sports and exercises. When a woman who has given birth to a child starts to exercise, she should pay attention to controlling the intensity of the exercise, starting with low-intensity exercises such as walking and brisk walking, gradually increasing the amount of exercise, and slowly transitioning to jogging, running and other exercise methods with a larger amount of exercise.
