When I searched “Google” I literally felt as though I should wrap myself in bubble wrap and stay away from everyone and everything, but I didn’t. Here are the factual answers to the top 5 questions about exercising while pregnant I get asked from pregnant moms.

What is a safe pregnancy heart rate while exercising?

When I first found out I was pregnant this is exactly what my doctor told me. I was terrified of a miscarriage and thought that if my heart rate went over 140bpm I could jeopardize my pregnancy.

What I didn’t realize at that time was that she didn’t know my history or my fitness level. It is critical that you find a physician that you feel comfortable with and one who really knows your history.

You will want to gauge your level of intensity by using the RPE (Rate of Perceived Exertion) 15 point scale. It is key to maintain a level where you can carry on a normal conversation with someone while keeping a steady breath.

If you were active before pregnancy, you more than likely can continue that level of intensity when exercising while pregnant. If you were strength training and running prior to getting pregnant, then you can continue that.

Please note: Your physician’s advice supersedes this. Wearing a heart rate monitor during pregnancy is not recommended because heart rates and effort will vary depending on each individual. Always listen to your body - you know best.

2. What exercises should I avoid during pregnancy?

There are some exercises that should be avoided during all trimesters of pregnancy.

Exercises that require lying flat

The American Congress of Obstetricians and Gynecologists (ACOG) warns that both lying down in the supine position and standing without moving, as well as certain yoga poses, should be avoided.

Any exercises that could result in falling or contact

You’ll also want to avoid contact sports or any activity where you could easily lose your balance and fall.

High Temperature Exercises

It is also recommended that you do not participate in hot yoga or hot Pilates.

3. If I haven’t exercised, can I or should I start?

It’s never too late to start. (Make sure you get your doctor’s clearance). Women who start exercising when they get pregnant can reach their fitness goals with consistent effort. The key is to start small, 15-20 minutes a day, 3-5 days a week of walking, swimming or strength training. You’ll gradually work up to 30-45 minutes a day, 3-5 days a week.

4. How much extra do I need to eat?

Pregnancy creates a high metabolic demand and a woman usually needs an additional 300 calories per day. Many women think that if they are pregnant that means they can eat whatever they want and desire. You have to remember that what you eat is not only affecting you but also the little one inside. Making sure that the extra 300 calories you consume is nutritious and filled with vitamins and minerals is key to a healthy pregnancy.

An hour before exercise, you will want to have a little snack that combines a complex carb (sweet potato, oatmeal, quinoa, etc.), a protein (lean meats or protein shake) and a little fat (avocado, nuts, nut butter, coconut oil, etc.). You’ll also want to keep your water intake up and sip 8-10 oz. every 15-20 minutes.

Working out and staying fit is not necessarily about preventing weight gain but more about maintaining or improving muscle mass and staying active, confident and healthy for the growing baby inside of you.

5. Will exercising while pregnant affect my labor and delivery?

I know from personal experience that we can have a master plan, but it doesn’t always go that way. However, I can say that staying fit throughout my pregnancy allowed me to withstand labor, feel more confident about my abilities, handle the pain better, and when it came time to push, to deliver my little one in 4 pushes.

I do understand that there are a lot of factors that we can’t control during labor and delivery and each person’s experience is different. Studies have shown that the babies of women who exercise seem to tolerate the stress of contractions better.


Staying fit throughout your pregnancy can improve your strength and confidence, and reduce some fears around labor and delivery. A huge bonus of staying fit during your pregnancy is that you will be able to recover and bounce back more quickly than if you had not been active while pregnant!  You should always get clearance from your doctor before starting a new program!
