What this page covers
  • ACOG recommends 150 minutes of moderate activity per week during pregnancy.
  • Walking, swimming, and prenatal yoga are among the safest options.
  • Certain warning signs require stopping exercise and contacting a provider.

ACOG Exercise Recommendations for Pregnancy

The American College of Obstetricians and Gynecologists recommends that pregnant women without complications get at least 150 minutes of moderate-intensity aerobic activity per week. This mirrors the general adult guideline and is safe for most pregnancies.

Regular prenatal exercise reduces the risk of gestational diabetes, preeclampsia, cesarean delivery, and excessive weight gain. ACOG notes that women who were active before pregnancy can generally continue their routines with modifications.

  • 150 minutes of moderate activity per week
  • Benefits include reduced gestational diabetes risk
  • Previously active women can continue with modifications

Safe Activities During Pregnancy

Walking, swimming, stationary cycling, and prenatal yoga are consistently recommended as safe throughout pregnancy. These activities provide cardiovascular benefits without excessive joint stress or fall risk.

ACOG advises avoiding contact sports, activities with fall risk, hot yoga, and any exercise performed while lying flat on the back after the first trimester. Scuba diving is also contraindicated due to pressure changes affecting the fetus.

  • Safe: walking, swimming, stationary cycling, yoga
  • Avoid: contact sports, hot yoga, scuba diving
  • No lying flat on back after first trimester

Warning Signs to Stop Exercise

ACOG identifies specific symptoms that require immediately stopping exercise and contacting a healthcare provider: vaginal bleeding, regular painful contractions, amniotic fluid leakage, dizziness, and chest pain.

Shortness of breath before exertion, calf pain or swelling, and headache are additional warning signs. These symptoms do not necessarily indicate a serious problem but require medical evaluation before resuming activity.

  • Stop for vaginal bleeding or fluid leakage
  • Stop for regular painful contractions
  • Contact provider before resuming after warning signs
