Are you hesitant to exercise during pregnancy for fear of causing a miscarriage? Learn why you can feel confident and informed about staying active during pregnancy with evidence-based information on exercise safety and health benefits for both mother and baby.


When it comes to exercising during pregnancy, many women are understandably cautious. There are a lot of myths and misconceptions out there about exercise and miscarriage, and it can be hard to know what’s true and what’s not. In this article, we’ll explore the question of whether exercise can cause miscarriage, and provide evidence-based information to help you feel confident and informed about exercising during pregnancy.

Debunking the Myths: The Truth About Exercise and Miscarriage

One of the most common myths about exercise and miscarriage is that strenuous activities like running or lifting heavy weights can trigger a miscarriage. However, there is no evidence to support this claim. Miscarriage is typically caused by chromosomal abnormalities or other genetic factors, and is not related to moderate exercise.

Another myth is that exercising during the first trimester is dangerous. In fact, exercise can be beneficial during this time as long as you listen to your body and avoid overexertion.

Finally, some people believe that exercise can steal nutrients from the developing embryo, causing a miscarriage. This is also untrue – in fact, regular exercise can improve blood flow to the uterus and placenta, providing vital nutrients to the fetus.

Staying Active During Pregnancy: Separating Fact from Fiction

Exercise during pregnancy has many benefits, including improved cardiovascular health, decreased risk of gestational diabetes and preeclampsia, and reduced likelihood of excessive weight gain. However, many women worry that exercise might harm their baby or be unsafe for them in some way.

In reality, moderate exercise is usually safe and healthy for both mother and baby. The American College of Obstetricians and Gynecologists (ACOG) recommends at least 150 minutes of moderate-intensity aerobic activity per week for pregnant women, unless there are specific medical conditions that require otherwise. It’s important to check with your healthcare provider before starting or continuing an exercise routine during pregnancy.

The Link Between Exercise and Miscarriage: What Current Research Tells Us

A study published in the journal Obstetrics and Gynecology found no significant association between exercise and risk of miscarriage. Another study published in the British Journal of Sports Medicine suggested that regular exercise before and during pregnancy may actually help reduce the risk of preterm birth.

It is worth noting, however, that most studies on exercise and miscarriage have been small and focused on specific populations, so we don’t have a complete understanding of the relationship between the two. More research is needed to fully understand the effects of exercise on pregnancy outcomes.

How Much Exercise is Safe During Pregnancy? An Expert’s Opinion

To get a better sense of how much exercise is safe and healthy during pregnancy, we spoke with Dr. Samantha Johnson, a certified exercise physiologist and prenatal fitness specialist.

“Moderate-intensity exercise is generally safe and healthy for most pregnant women,” says Dr. Johnson. “Aim for 30 minutes of moderate-intensity activity on most days of the week, and avoid high-intensity or contact sports that could pose a risk of injury.”

Exercising Safely While Pregnant: Tips and Precautions

While exercise during pregnancy is generally safe, there are some precautions and modifications you should be aware of. For example, avoid exercises that involve lying flat on your back after the first trimester, as this can reduce blood flow to the uterus. It’s also important to stay well-hydrated and to avoid becoming overheated.

If you’re new to exercising, start slowly and gradually build up your intensity and duration. Listen to your body and stop exercising if you experience any pain, discomfort, or shortness of breath.

The Benefits of Staying Active While Pregnant: Dispelling Common Misconceptions

Regular exercise during pregnancy can have numerous benefits, including improving cardiovascular function, boosting mood, and reducing the risk of gestational diabetes and preeclampsia. Contrary to what some people believe, exercise does not increase the risk of preterm labor, low birth weight, or developmental delays.

In fact, exercising during pregnancy can have positive benefits for your baby as well. A study published in the journal Medicine & Science in Sports & Exercise found that newborns of mothers who exercised during pregnancy had better neuromotor development than those of sedentary mothers.


The bottom line is that exercise during pregnancy can be safe and healthy for both mother and baby. The key is to listen to your body, follow your healthcare provider’s guidance, and aim for moderate-intensity activity on most days of the week. By doing so, you can enjoy the many benefits of exercise while staying healthy and well during pregnancy.
