Pregnancy Workouts: How to Monitor your Symptoms & Why it is Important to Continue Physical Activity

Updated: May 18

Learn more about how to monitor yourself while working out when pregnant, the research behind why it is safe for most women to continue to workout while pregnant, and what the American College of OBGYN recommends for weekly physical activity.




In my interactions with new mothers, I was surprised to find that many were misinformed or unaware of their options for prenatal exercise and if it was a safe option for them. One study found that one-third of women surveyed did not receive advice about physical activity during prenatal care [1]. Doesn’t that sound like a lot of women? At Pacer PT we are looking to bring more awareness to taking care of your body and maintaining your fitness routines during and after pregnancy. If you’re looking for more info about what your options are for prenatal exercise read on!




There are exercises and various strategies you can take to make exercising while pregnant comfortable, safe, and effective to meet your fitness goals. Understanding what to monitor when working out and what exercises may be right for you can improve your delivery process, protect you against eclampsia (high blood pressure during pregnancy), improve gestational weight, and lower risk of depression [2].

SIGN ME UP! The biggest thing to keep in mind is that EVERY pregnancy is different, and just because you know a friend who did cross-fit or ran until she delivered her baby, does not mean that it is the right path for you. Be mindful of your precautions and how to monitor your body’s response during and after exercise so you can set yourself for success.

How to monitor yourself to see if exercise is appropriate for you:

All pregnant women can participate in physical activity throughout pregnancy with the exception of the contraindications (AKA advised against) listed below:

Red Light: (Absolute Contraindications) Stop! Consult a health care professional and note exercise may not be appropriate for you if you have:

- Severe respiratory disease, severe acquired or congenital heart disease with exercise intolerance, uncontrolled or severe arrhythmia, placenta abruption, vasa previa, uncontrolled type 1 diabetes, intrauterine growth restriction, active preterm labour, severe pre-eclampsia, cervical insufficiency [2]

Yellow Light: (Relative contraindications) Proceed with caution and do not hesitate to address your concern or questions with your health care provider if you have:

- Mild Respiratory disorders, mild congenital or acquired Heart Disease, well-controlled type 1 diabetes, mild pre-eclampsia, preterm premature rupture of membranes, placenta previa after 28 weeks, untreated thyroid disease, symptomatic severe eating disorder, multiple nutrient deficiencies, mod-heavy smoking (>20 cigarettes per day)


Green light: GO GO AND KEEP ON GOING- Any other circumstance; whether you were ACTIVE or NOT before you were pregnant! [2]

Be sure if you are continuing to workout while pregnant that you are monitoring your heart rate, and be sure that you are able to talk during the workout as to assume you are keeping an intensity that is manageable for you. You should be able to keep an even breath during exercise and AVOID holding your breath with any lifting, pushing, or abdominal exercise as this can elevate your heart rate and blood pressure dramatically. [3]

Why you should exercise during pregnancy:


The first thing to think about before deciding what type of workout to do while pregnant is to be mindful about what type of exercise(s) you were doing before you were pregnant. Many of my clients, who when speaking to their doctor about exercising while pregnant, did not receive any questions from their doctor about what exercise they did prior to pregnancy.


Advocate for yourself and tell your doctor what type of physical activity you were partaking in before you were pregnant and at what frequency and intensity so they can help guide you with recommendations!


If your doctor has given you specific instructions not to workout, then do so, but, be sure to have questions lined up on why exercise may not be appropriate for you and what alternative options may be appropriate forms of physical activity. We all need to be mindful of our mental and physical health and what will make us feel good during this time.

As per the most recent Canadian guidelines for exercising while pregnant and from the American College of Obstetrics and Gynecology (ACOG), performing 150 minutes per week of moderate intensity exercise is beneficial for women without contraindications. This means about 30 minutes of physical activity at least 5 day per week. [3,4] The benefits this can have on your body include improvements in cardiovascular, mental, and metabolic health!

What do you mean aquatic workouts?!


If working out on land is starting to feel challenging in your second or third trimester, consider exercising in water! Submerging your body in water will decrease body weight forces and will facilitate movement, decreasing overload on the joints. This will enable you to focus on your breathing and can promote faster stages of LABOR- YES YES and YES!

One study showed the first and second stages of labor were FASTER in those who exercised compared to their non-exercised counterparts. The total time of delivery was almost 3 HOURS less! [4]

Recommendation for aquatic workouts include 60 minute sessions 3 times a week; broken into 45 minutes of activity followed by 15 minutes of relaxation. Don’t forget to consult a medical professional before starting aquatic workouts, to confirm if it is safe for you.

Otherwise, GREEN LIGHT – get in the water ladies!


When to modify exercise while working out pregnant:


This can vary from person to person. I know - not what you wanted to hear, but this is why it is so important to be familiar with the contraindications and to have the right questions to ask your doctor on your check ups, otherwise things can be missed.

In the first trimester many women may not feel well and could experience symptoms of nausea, vomiting, fatigue, or intolerance to higher-impact activities. By the second trimester, mom-to-be may be feeling more energized and by this point, may feel like it may be too late to exercise. If this sounds like you, DON’T give up. Try to slowly ease back into exercise again even in the middle of your second trimester, but remember to be mindful of the intensity of the exercise you are choosing. Think of restarting exercise in this stage almost like you are recovering from an injury or cold. Start slow, walk or lift lighter weights, then build up as tolerated.


Keep in mind it is important to continue to keep your core and pelvic floor connection to prevent lower back pain, pubic pain, and assist in recovery postpartum, so at the very least try to do exercises to assist in keeping these areas strong.
