How can I safely exercise while pregnant?

Exercise during pregnancy is generally considered safe for most healthy women and can even relieve some of the discomforts of pregnancy. Some forms of exercise that are particularly good for pregnant women are walking, swimming, stationary cycling, and yoga.

The American College of Obstetricians and Gynecologists recommends that you focus on non-weight-bearing activities and those that don't require an enormous amount of balance (so some of those extremely challenging yoga postures may be out until postpartum). Wear loose-fitting, lightweight clothing while exercising, get plenty of fluids, and don't work to the point of exhaustion. When you reach your second and third trimesters, don't do exercises that require lying on your back, and never do workouts that pose a risk of trauma to your abdomen while pregnant. And always be sure to check with your doctor about any exercise program before getting started. Some women -- such as those with preeclampsia, preterm labor, and hypertension or heart disease -- may be advised not to exercise or to pursue very limited physical activities while pregnant.
