Pregnant women really dream of a healthy pregnancy. To be able to have a healthy pregnancy, pregnant women can do pregnancy exercises. An old method that is still used in pregnancy services today is pregnancy exercise, where pregnancy exercise is also a method of relaxation and exercise for pregnant women which is a permanent program in antenatal care, aimed at making pregnant women mentally and physically ready to face the birthing process.
