Doing exercise during pregnancy doesn't seem to lower the chances of needing a C-section, forceps, or heavy bleeding after birth, at least for healthy pregnant women with a normal weight.

For healthy pregnant women with a normal weight, doing structured exercise or getting motivational counseling doesn't seem to change their chances of getting gestational diabetes, high blood pressure during pregnancy, having a baby too early, or the baby's weight at birth.

Working out while pregnant doesn't make it more likely for a mom to lose the baby, have the baby too early, or have a baby with low weight — it's generally safe for most pregnant women.

If a pregnant woman who might develop high blood pressure exercises at a moderate pace, it won't make her baby smaller — so it's safe for the baby's growth.

If a woman keeps exercising at the same level she did before getting pregnant, she’s less likely to run into pregnancy-related health problems than if she cuts back on exercise.

If you're having a normal pregnancy, staying active with workouts like walking, swimming, or light weight training can help you stay fit and make your pregnancy go more smoothly.
