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.

Being active during pregnancy is generally safe and helps most women feel better, stay fit, manage their weight, lower their chance of getting gestational diabetes (especially if they're overweight), and feel less stressed — so doctors often recommend it for healthy pregnancies.

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 a pregnant woman gets at least 150 minutes of moderate exercise each week, she’s less likely to develop gestational diabetes, high blood pressure during pregnancy, or pre-eclampsia.

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 pregnant women who are at moderate risk for high blood pressure do more physical activity each week, their babies tend to be born later and weigh more at birth, which might help the baby grow healthier without becoming too big.
