Pregnant women without medical or obstetric problems should be encouraged to exercise. The paucity of experimental data on exercise in pregnancy forces recommendations to be drawn from a synthesis of available information. Vigorous exercise during pregnancy seems to pose no adverse maternal or neonatal outcomes. Nonetheless, the safety of vigorous exercise necessitates surveillance of fetal growth, the woman's weight, nutritional intake, and exercise duration and intensity.
