More walking by pregnant women can help smooth labor, but it should be done in moderation, and it is recommended to consult a professional doctor to formulate a reasonable exercise program. Appropriate exercise during pregnancy, such as walking and yoga for pregnant women, can strengthen the body’s muscle strength, reduce edema, and enhance the physical strength of pregnant women during labor and delivery, thus facilitating labor and delivery, which will have a positive effect on a smooth delivery and reduce unnecessary caesarean sections. Appropriate exercise during pregnancy is also conducive to controlling the weight of pregnant women, and has a positive effect on the prevention of gestational diabetes, pre-eclampsia and other pregnancy complications. However, it should be noted that exercise during pregnancy should be in moderation, and if any discomfort occurs during exercise, such as abdominal pain, redness, etc., the exercise should be stopped immediately, and if necessary, timely medical treatment should be sought.
