Exercise During Pregnancy

For most pregnancies without complications, exercise is not just safe — it's actively recommended. ACOG endorses at least 150 minutes/week of moderate-intensity aerobic activity, plus strength training, throughout pregnancy. Benefits include lower risk of gestational diabetes, preeclampsia, excessive weight gain, cesarean, and depression, plus faster postpartum recovery. Most people can continue whatever they were doing before pregnancy at a modified intensity; new-to-exercise people should start gradually. Contact sports, activities with fall risk (skiing, horseback riding), scuba diving, and hot yoga are generally avoided.

• Feeling short of breath, dizzy, or lightheaded during exercise

  Within the range of normal

  Mild breathlessness (can still talk in short sentences) and being unable to hit prior paces are expected.

  Call your healthcare team if

  Chest pain, severe shortness of breath, dizziness that doesn't clear with rest, calf pain/swelling, headache, vaginal bleeding, leaking fluid, decreased fetal movement, or regular painful contractions — stop and call.

Educational reassurance only — never a substitute for your care team's advice. When in doubt, call.

ACOG Committee Opinion 804 (Physical Activity and Exercise During Pregnancy and the Postpartum Period) is the primary US source. Cochrane reviews support exercise for reducing GDM, preeclampsia, and excessive weight gain. Canadian and UK guidelines (SOGC, RCOG) align.

For most topics, guidelines from ACOG, WHO, and other major bodies broadly agree on the core safety points (when to act in an emergency, informed-consent standards, monitoring baselines). Where reasonable people — and even guidelines — differ tends to be around thresholds (when to start or stop something), preferences (comfort, environment, support), and values (how you weigh small risks against benefits). Use the questions below to explore those pieces with your care team.

Educational only. Your care team can help you weigh what applies to your specific situation.

• Prenatal Nutrition — What Actually MattersWhich nutrients have real evidence behind them in pregnancy, what to eat vs. avoid, and how to handle nausea, aversions, and 'eating for two' myths.
• Weight Gain in PregnancyWhat the IOM ranges are, why they're a range and not a target, and what to do if you're gaining more or less than expected.
• Gestational Diabetes (GDM)Higher-than-normal blood sugar first identified in pregnancy; usually managed with diet and monitoring, sometimes with medication.
• Preeclampsia (High Blood Pressure + Protein in Urine)A pregnancy-related condition where blood pressure rises after 20 weeks, often with protein in the urine or other signs of organ strain.
• Pelvic Floor RecoveryWhat the pelvic floor is, how birth changes it, and when to see a pelvic floor physical therapist.
• Common Pregnancy Discomforts — What Helps and What to Call AboutA running guide to nausea, heartburn, constipation, round-ligament pain, back pain, swelling, insomnia, and more — with specific 'when to call' thresholds.

A short BRAIN-style set you can bring to any conversation about interventions, monitoring, or care decisions.

• ?Why are you recommending this now — is it urgent, routine, or optional?
• ?What happens if we wait an hour (or longer) before deciding?
• ?What signs would tell us this is working — or that we need to change course?
• ?What are the alternatives, including doing nothing?
• ?What would you recommend if this were your family?
• ?What would change your recommendation?
