Let’s begin by addressing a common concern many pregnant women have:
Is It Safe to Exercise During Pregnancy?
The safety of exercise during pregnancy is one of the most common concerns for expecting mothers—and it’s a valid one. Fortunately, decades of medical research and clinical guidance confirm that staying physically active during pregnancy is not only safe for most women, but actually recommended by leading health organizations around the world.
What the Experts Say
According to the American College of Obstetricians and Gynecologists (ACOG), pregnant women without medical complications should aim for at least 150 minutes of moderate-intensity aerobic activity per week. This includes activities like brisk walking, swimming, or prenatal yoga. ACOG emphasizes that exercise offers significant benefits for both mom and baby, including reduced risk of gestational diabetes, hypertension, and cesarean delivery.
The World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) also align with this guidance. These organizations recommend that pregnant individuals continue or begin safe physical activity unless they have medical conditions that warrant restrictions.
