ACOG recommends at least 150 minutes of moderate-intensity exercise per week throughout pregnancy. Regular physical activity reduces the risk of gestational diabetes, preeclampsia, cesarean delivery, and excessive weight gain. Safe activities include walking, swimming, prenatal yoga, cycling (stationary), and strength training with modifications.
🏃♀️ Why Exercise Is Important During Pregnancy

- Reduced risk of gestational diabetes by up to 50% with regular exercise.
- Lower risk of preeclampsia (pregnancy-related high blood pressure).
- Healthy weight management within recommended ranges.
- Reduced back pain and pelvic discomfort through strengthened muscles.
- Better mood and reduced anxiety/depression.
- Improved sleep quality.
- Easier labor and recovery — fit women often have shorter labors.
- Reduced risk of cesarean delivery.

❓ FAQ
How much exercise should I do during pregnancy?
ACOG recommends at least 150 minutes of moderate-intensity exercise per week — about 30 minutes on most days. If you were active before pregnancy, you can usually continue your routine with modifications.
Can I run during pregnancy?
If you were a runner before pregnancy, you can usually continue running with modifications (slower pace, flat terrain, proper hydration). If new to running, start with walking or swimming instead.
Can exercise cause miscarriage?
No. Moderate exercise does not increase the risk of miscarriage. Regular physical activity is associated with better pregnancy outcomes.
Is it safe to do ab exercises while pregnant?
Modified core exercises are safe and beneficial. Avoid traditional crunches after the first trimester. Planks (modified), bird-dogs, and pelvic tilts are good alternatives.
