Walking— The explanation appears to be that the pressure of your baby’s head pressing down on the cervix stimulates the release of oxytocin, hopefully bringing on labor, also just being upright gets the forces of gravity working for you, encouraging the baby to move down into the pelvis. Be careful not to wear yourself out. Labor can be exhausting and you don’t want to use up all your energy before you have begun. This is not the moment to take up power walking, particularly if you have not done much exercise earlier on in your pregnancy. A gentle stroll is probably the best you will be able to manage.
