Guidelines of the American College of Obstetricians and Gynecologists for exercise during pregnancy and the postpartum period

Pregnancy should not be a state of confinement, and pregnant women with uncomplicated pregnancies should be encouraged to continue and engage in physical activities. Recreational and competitive athletes with uncomplicated pregnancies may remain active during pregnancy, and modify their usual exercise routines as indicated in this review. All active pregnant women should be examined periodically to assess the effects of their exercise programmes on the developing fetus, so that adjustments can be made if necessary. Women with medical or obstetric complications should be carefully evaluated before recommendations on physical activity participation during pregnancy are made. Despite the fact that pregnancy is associated with profound anatomical and physiological changes, exercise has minimal risks and confirmed benefits for most women.
