Pregnancy is a unique time that calls for extra care and attention to your health. As someone passionate about wellness, I believe staying active during pregnancy can make a big difference for both you and your baby.
Based on trusted advice from organizations like the American College of Obstetricians and Gynecologists (ACOG) and the Centers for Disease Control and Prevention (CDC), this article covers the essentials of exercising safely while pregnant. Keep in mind that everyone’s situation is different, so checking in with your doctor is a must.
Benefits of Staying Active During Pregnancy and General Safety Tips
Regular exercise during pregnancy brings a host of benefits. It can boost your chances of a smoother vaginal delivery and lower the risk of issues like excessive weight gain, gestational diabetes, high blood pressure conditions (like preeclampsia), preterm birth, or needing a cesarean.
It also helps ease common aches, such as back or sciatic pain, and may even lower the chances of postpartum depression. Staying active keeps your heart and lungs strong, lifts your mood, and can make it easier to return to your pre-pregnancy weight when paired with healthy eating.
Research shows active moms often have lower rates of preterm birth and better control over conditions like gestational diabetes.
According to experts at ACOG, CDC, and the World Health Organization (WHO), exercise is generally safe for most pregnant women with uncomplicated pregnancies.
The key is to start with a doctor’s evaluation to ensure it’s safe for you, stick to moderate activities, and adjust for the physical changes pregnancy brings.
Routine bed rest isn’t recommended to prevent preterm birth, as it could lead to problems like blood clots or loss of strength. Aim for at least 150 minutes of moderate aerobic activity each week, spread out in a way that works for you.
Safe and Beneficial Exercises vs. Ones to Skip
When choosing exercises, focus on low-impact options that build strength and stamina without risking injury. Here’s a breakdown of what’s safe and what to avoid, based on ACOG recommendations:
|
Category |
Safe and Beneficial Exercises |
Exercises to Avoid |
|---|---|---|
|
Aerobic |
Walking, stationary cycling, swimming, low-impact aerobics, dancing |
High-impact sports (e.g., running if you weren’t already a runner), contact sports (e.g., soccer, basketball) that risk belly bumps |
|
Strength/Resistance |
Lightweight training, resistance bands, modified yoga (avoid lying flat after the first trimester), stretching |
Heavy lifting that strains your core, exercises involving holding your breath with force |
|
Other |
Water therapy, adapted Pilates |
Scuba diving (risks gas bubbles for the baby), high-fall-risk activities (e.g., skiing, horseback riding), hot yoga, or exercising in extreme heat |
Walking and swimming are great choices, widely studied for their safety and benefits. Steer clear of high-impact sports or activities where you might fall, as they can cause injury or stress your joints. Strength training is fine for most healthy pregnancies, as long as it’s done carefully.
Adjusting Exercise Across Pregnancy and Tracking Effort
Your exercise routine may need tweaks as your pregnancy progresses, though many healthy women can keep up vigorous activity even late in pregnancy.
In the first trimester, start slowly, especially if you’re new to exercise, and avoid overheating (like hot yoga) to protect your baby’s early development. Aim for 150 minutes of moderate activity per week, building up gradually if you’re starting.
In the second trimester, you can often maintain your intensity, but watch your balance as your body changes. After 20 weeks, avoid lying flat on your back for long to prevent pressure on major blood vessels, which can cause dizziness.
By the third trimester, you might shorten sessions (e.g., keep workouts under 45 minutes to avoid low blood sugar) and stick to low-impact options like walking. Make sure you’re eating enough to fuel your activity. If you’re at high altitudes (above 6,000 feet), take extra care and consult your doctor.
To gauge effort, use the “talk test” – you should be able to chat comfortably while exercising, or aim for a “somewhat hard” feeling (about 13–14 on the Borg effort scale).
Heart rate isn’t the best measure during pregnancy, as it can vary.
Warning Signs to Stop Exercising
Stop exercising right away and call your doctor if you notice any of these symptoms, which could signal a problem:
- Vaginal bleeding
- Abdominal pain or regular, painful contractions
- Leaking amniotic fluid
- Shortness of breath before starting exercise
- Dizziness or headaches
- Chest pain
- Muscle weakness that affects balance
- Calf pain or swelling (could indicate a blood clot)
Other red flags include an irregular heartbeat or less fetal movement. ACOG highlights these as signs to take seriously and seek medical help promptly.
Medical Conditions and Pregnancy Complications That Affect Exercise
Some health conditions or pregnancy issues may call for a customized exercise plan or rule out certain activities. ACOG lists conditions where exercise might not be safe or needs extra caution:
Absolute no-go conditions (exercise isn’t allowed):
- Serious heart or lung disease
- Weak cervix
- Carrying multiples with preterm labor risk
- Ongoing bleeding in the second or third trimester
- Placenta previa after 26 weeks
- Premature labor or ruptured membranes
- Preeclampsia or high blood pressure from pregnancy
Conditions needing caution (exercise with close monitoring):
- Severe anemia
- Heart rhythm issues have not yet been evaluated
- Chronic lung issues
- Poorly controlled diabetes
- Extreme obesity or underweight
- Very inactive lifestyle history
- Baby growth issues
- Uncontrolled high blood pressure or seizures
- Heavy smoking
- Joint or bone problems
For these, work with your doctor to create a plan that balances benefits and safety. Even mild conditions, like controlled preeclampsia, may allow some activity with supervision.
Supporting Safe Exercise: Hydration, Clothing, and Warm-Ups
Beyond choosing the right exercises, a few practical steps help keep you safe.
Hydration is crucial; drink water before, during, and after exercise to avoid dehydration, which can cause dizziness or affect your baby. This is especially important in hot weather or if you’re breastfeeding after delivery.
Wear loose, breathable clothing, supportive shoes, and bras to stay comfortable and accommodate your changing body. Avoid tight outfits that could overheat you, particularly early in pregnancy.
Warm-up and cool-down routines are non-negotiable. Spend 5–10 minutes warming up with gentle movement (like slow walking) to get your blood flowing, and cool down with stretching to stay flexible and reduce soreness. These steps help your body adjust to pregnancy hormones that loosen joints.
Why You Should Talk to Your Doctor First
Before starting or changing your exercise routine, always check with a healthcare provider, like your obstetrician or a physical therapist. They can tailor a plan to your health, pregnancy stage, and any medical issues.
This is especially important if you have complications, are an athlete, or have specific health concerns. Ongoing care ensures you stay safe while reaping the benefits of exercise. Skipping this step could result in missing hidden risks, so make it a priority to get professional input.
In short, exercising during pregnancy can be a game-changer for your health and your baby’s, as long as it’s done thoughtfully. Follow these guidelines, listen to your body, and work closely with your healthcare team for the best experience.
