Does exercise during pregnancy decrease maternal risk of developing high blood pressure during pregnancy?  Yes, and here is how to do it. 

If you are already an exerciser, continue!… although modifications may be needed.   If you are new to exercising, initiate an exercise regimen early in pregnancy. 

Aerobic exercise performed for at least 30 minutes 3-4 times per week decreases maternal risk of high blood pressure during pregnancy (including gestational hypertension and preeclampsia). The American College of Obstetricians and Gynecologists recommended in their 2020 updated committee opinion that “physical activity and exercise in pregnancy are associated with minimal risks and have been shown to benefit most women, although some modification to exercise routines may be necessary because of normal anatomic and physiologic changes and fetal requirements.”
