Why It’s Important to Stay Active Safely During Pregnancy

Many people worry that exercise during pregnancy might harm the baby or cause complications. In reality, moderate, well-designed exercise routines can lead to significantly better outcomes for both the pregnant person and the baby. The key is learning how to stay active safely—tailoring your movement to your trimester and your own body’s needs.

Benefits of Staying Active During Pregnancy

The physical and psychological benefits of prenatal exercise are well-documented. According to the American College of Obstetricians and Gynecologists (ACOG), pregnant individuals without medical complications should aim for at least 150 minutes of moderate-intensity aerobic activity per week.

Here’s a breakdown of the primary benefits:

CategoryBenefits of Exercise During Pregnancy
Physical HealthImproved cardiovascular health, better posture, stronger muscles and joints, reduced back pain, and improved balance.
Weight ManagementHelps regulate weight gain within healthy limits, lowering the risk of gestational diabetes and preeclampsia.
Labor & DeliveryIncreases endurance and strength, which can lead to shorter, less complicated labor.
Postpartum RecoveryFacilitates quicker recovery, supports hormonal balance, and prevents postpartum weight retention.
Mental HealthReduces symptoms of anxiety and depression, boosts mood through endorphins, and promotes better sleep.

Fact: A 2020 study published in the British Journal of Sports Medicine found that women who exercised regularly during pregnancy had a 40% lower chance of developing major pregnancy complications compared to those who remained sedentary.

When Exercise Is NOT Recommended

While exercise is generally safe for most pregnant people, there are some conditions that require caution or complete avoidance of physical activity. Always consult with your OB-GYN or midwife before beginning or continuing any exercise program.

Contraindications to Exercise During Pregnancy Include:

  • Severe anemia
  • Placenta previa after 26 weeks
  • Cervical insufficiency or cerclage
  • Multiple gestation with risk of preterm labor
  • Preterm labor during the current pregnancy
  • Persistent second or third-trimester bleeding
  • Pre-eclampsia or pregnancy-induced hypertension
  • Significant heart or lung disease

“The most important thing is listening to your body and your doctor. Pregnancy is not the time to push limits—it’s a time to move mindfully.” – Dr. Lisa Callahan, OB-GYN

How to Stay Active Safely During Each Trimester of Pregnancy: General Guidelines

Before diving into trimester-specific advice, it’s helpful to understand the universal principles for safe pregnancy fitness:

Core Guidelines for Safe Prenatal Exercise

  1. Get Medical Clearance First – Especially if you weren’t active before pregnancy.
  2. Hydrate Regularly – Dehydration can lead to overheating and even contractions.
  3. Avoid Overexertion – Use the “talk test”: If you can’t speak in full sentences, you’re working too hard.
  4. Wear Supportive Clothing and Footwear – This includes a good sports bra and supportive shoes.
  5. Avoid Lying Flat on Your Back After Week 16 – This can restrict blood flow.
  6. Don’t Start Something New and Intense – Pregnancy isn’t the time to start training for a marathon.
  7. Watch for Warning Signs – Such as dizziness, vaginal bleeding, chest pain, or shortness of breath.

Types of Safe Exercises During Pregnancy (All Trimesters)

There are several low-impact and safe options that can be adapted throughout pregnancy:

  • Walking – Simple, accessible, and effective.
  • Swimming & Water Aerobics – Buoyancy relieves pressure and cools your body.
  • Prenatal Yoga – Focuses on flexibility, breathing, and relaxation.
  • Pelvic Floor Exercises (Kegels) – Strengthens muscles important for labor and recovery.
  • Stationary Cycling – Low risk of falls and a great cardio option.
  • Strength Training (Bodyweight or Light Weights) – Keeps muscles strong, supports joints, and helps posture.

“Strength training during pregnancy can help prevent common aches and pains, such as back and hip pain, and help maintain functional strength for labor and motherhood.” – Megan Davidson, Doula & Exercise Specialist

How to Stay Active Safely in the First Trimester of Pregnancy

The first trimester (weeks 1 to 13) can be both exciting and overwhelming. Your body is undergoing a surge of hormonal changes—estrogen, progesterone, and hCG levels spike dramatically, often causing fatigue, nausea, breast tenderness, and mood swings. As your body adapts to supporting a developing embryo, you might feel exhausted even if you’re doing less than usual. That’s why safe and gentle activity is recommended during the first trimester, not intense or high-risk movement.

What’s Happening in Your Body

  • Fatigue is one of the most common symptoms due to increased progesterone and blood volume.
  • Your core temperature may rise slightly, so overheating becomes a concern during exercise.
  • You may start to feel nauseous, making exercise feel like the last thing you want to do.
  • Joints begin to loosen due to the hormone relaxin—this increases flexibility but also injury risk.

Understanding these changes is crucial when planning your activity level. This is not the time to push your limits—it’s a time for consistency, not intensity.

Best Exercises for the First Trimeste

If you were active before pregnancy, you can usually continue most of your regular workouts with some modifications. If you were not active, the first trimester is a great time to ease into a prenatal fitness routine.

Top Safe Exercises for the First Trimester

Exercise TypeWhy It’s Safe and Beneficial
WalkingLow-impact and can be done anywhere. Helps with digestion and fatigue.
Prenatal YogaEncourages breath control, relaxation, and pelvic floor awareness. Great for nausea and stress.
Swimming or Water AerobicsEases joint pressure and helps regulate body temperature.
Stationary CyclingProvides cardiovascular benefits with no risk of falling.
Light Strength TrainingHelps with posture, core stability, and strength needed for carrying the baby and delivery. Use bodyweight or light weights.
KegelsStrengthens pelvic floor muscles, helping with delivery and recovery.

Pro Tip: Start with just 10–15 minutes a day, then gradually increase to 30 minutes. Even short, consistent workouts can boost energy and improve mood.

Exercises to Avoid in the First Trimester

While movement is beneficial, there are certain activities that increase risk of injury, overheating, or trauma in early pregnancy.

Avoid the Following:

  • High-impact sports (soccer, basketball)
  • Hot yoga or heated workouts
  • Exercises involving deep abdominal work or crunches
  • Activities with a fall risk (horseback riding, skiing)
  • Lying flat on your back for extended periods (especially after week 12)
