Congratulations on your pregnancy! I am so proud of you for taking the time to invest in your health and also your new baby’s health while being pregnant. 

I want you to know right now before diving deep into this article whether or not exercise is safe. The answer is YES!

Is Exercise Safe During Pregnancy

 

Like I just mentioned, exercise is safe during pregnancy (for most women). Of course I can’t say that it’s safe for every single pregnant woman in the world because everyone has their own medical history. If you are suffering from a health condition, consult your doctor before beginning an exercise routine. 

Generally speaking, physicians recommend that women who are pregnant should exercise to maintain a healthy weight and remain physically fit.

A good rule of thumb that many doctors say is:

“If you were physically active before you were pregnant, it is likely safe to remain active during pregnancy. Continue to do the same or decreased intensity workouts but do not increase the intensity of your workout compared to pre-pregnancy.”

I always recommend for you to first get a prenatal care check-up (around 8 to 10 weeks pregnant) prior to beginning a workout for the first time during pregnancy. This is when you ask your doctor’s approval to begin working out and what restrictions your doctor might have for you specifically. 

If you have been working out for several months or years prior to pregnancy and you just found out you’re pregnant, I would say you are safe to continue working out. Just be sure to check out this list of 37 exercises to avoid while pregnant

Can Exercise During Pregnancy Cause Miscarriage

 

If you have had this worry in the back of your mind that exercise can induce a miscarriage or cause your baby to be premature or have a low birth weight, I want to clear the air right now and tell you no, you are not at a higher risk of any of those. There is no evidence that proves exercise is the cause of miscarriage or premature babies. So I highly encourage you to get those thoughts out of your head if that’s something that has been filling your mind.

Exercise is safe during pregnancy only if you are doing it for the right reasons. If you are trying to exercise for weight loss purposes, then it becomes unsafe. The goal is not for weight loss but for the following benefits:

    Why Is Exercise Important During Pregnancy?

    1. Help prepare your body for labor and delivery and reduce your chance of c-section

    The stronger your body is, the more prepared you are for labor. Labor is no joke. It takes strength, endurance and power. You’re training for the marathon of your life: child birth!!

    2. Improve your heart rate which will help with labor and delivery

     

    Childbirth requires endurance – endurance to keep pushing, breathing, typically without rest breaks. You need your heart to be just as strong as your other muscles in your body. Strengthen your heart so that you can withstand the cardiovascular challenge from labor and delivery.

    3. Improves your level of energy throughout the day

     

    Pregnancy can be fatiguing. Well, it is fatiguing. Your body is working none stop to grow a baby. Exercise is known for improving energy levels. You might feel fatigued right after a workout, but your body will adapt and have more energy day after day.

    4. Help prevent injury

    Conditioning your body with exercise during pregnancy will only help your body to withstand the rapid changes that take place during the next 9 months. Hormone fluctuations cause your ligaments to become lax and thus increases your chance of injury. That is why so many women are prone to injury during pregnancy. Prevent this from happening to you by conditioning your muscles and ligaments.

    5. Be able to tolerate the increased weight gain from your growing belly

     

    Just imagine a giant bowling ball was attached to your body, with no preparation or conditioning to withstand the added weight. That would hurt. If you exercise and prepare your body for the added weight gain, your legs and back will be able to tolerate it more. Going up stairs and walking longer distances will be easier when the 3rd trimester comes around since you’ve been working out consistently.

    6. Combat gestational diabetes and pre-eclampsia

    Gestational diabetes is a kind of diabetes that can happen during pregnancy. It’s a condition in which your body has too much sugar (called glucose) in the blood. Pre-eclampsia is a kind of high blood pressure some women get after the 20th week of pregnancy or after giving birth. These conditions can increase your risk of having complications during pregnancy, like premature birth (birth before 37 weeks of pregnancy).

    7. Decrease stress and improves your mood

    Exercise is known to release endorphins which helps combat stress. Pregnancy can be quite stressful with the rapid hormonal changes, morning sickness and lack of sleep. Exercise can help mitigate those negative factors by reducing your stress levels. 

    8. Improve sleep habits

     

    As your belly continues to grow and your bladder continues to get compressed, sleep will inevitably be disturbed. Help sleep better at night with the benefits of exercise being a natural sleep inducer.

    9. Decrease back pain and other body aches

     

    Physical therapists prescribe exercise to treat back pain in pregnant women. Why not work preventatively by doing those exercises before the back pain begins?

    Back pain is common in pregnancy due to the added pressure on the spine from the ligaments that are stretching with your growing belly. Maintain a strong back to prevent back injury during pregnancy.

    10. Improve GI tract and reduce constipation

    Exercise is a natural GI stimulator. Muscle contractions that occur during exercise will help to stimulate the natural contraction of intestinal muscles as well.

    11. Reduces swelling in your lower legs and feet

    Swelling in the lower legs during pregnancy is extremely common, especially in the 3rd trimester as blood volume increases and veins begins to expand, thus valves start working improperly. Exercise, specifically lower body exercise, can help to reduce swelling by pumping blood back up to the heart and assisting in normal vein function. 

     

    Medical Conditions That make Exercise During Pregnancy Unsafe 

     

    Some women should avoid exercise while pregnant. In this article the March of Dimes lists examples of pregnancy complications women might suffer from. In these certain conditions, you would want to avoid exercise during pregnancy:

    Preterm labor or bleeding from the vagina

    Twins, triplets or other multiples

    Gestational hypertension – also known as pregnancy induced hypertension

    Pre-eclampsia – for more information visit preeclampsia.org

    Placenta previa – for more information visit americanpregnancy.org

    Anemia (or other heart and lung conditions) – for more information visit webmd.com

    If you are unsure if you have any of these diagnoses or are concerned about the risk of exercise related to your individual health, I highly recommend following up with your physician before beginning an exercise routine. Your gynecologist can screen you for any of these conditions listed above plus more. 

    Exercise Guidelines

     

    You may want to include these basic guidelines in planning exercise during pregnancy: 

    1. Wear proper foot wear that fits snuggly so that you are less likely to sprain your ankle during a workout routine. Make sure there is enough arch support since you will be having added weight gain.

    2. Wear loose fitting clothing that is comfortable around your growing body. Maternity activewear is definitely the way to go.

    3. Exercise in a place where you are less likely to slip, trip and fall. Flat, dry environments are best.

    4. Avoid exercise in extreme weather like hot, humid days or freezing cold temperatures. Also avoid rainy days. Dry comfortable temperatures is always best.

    5. When transitioning from the floor, be sure to perform a log roll rather then sitting up (which strains your core). Move slowly and roll to your side, then push up to a sitting position before rising to your feet.

    6. Be sure to eat the proper amount of healthy calories to supplement your workout. Be sure never to burn more calories than you consume.

    7. Be sure not to consume a large meal right before exercising. It’s recommended to eat 1 hour prior to exercise or wait until your workout is finished before eating.

    8. Drink water before, during and after your workout. The recommended amount of water a day is 8 – 8 oz glasses. Keep drinking!!!

    9. Get your doctor’s approval before beginning an exercise routine for the first time during pregnancy. When you do begin exercising, start very slowly and monitor your body’s response to exercise. If you have pain, stop that exercise completely. If you have pain and muscle soreness days after your workout, cut back on some of the exercises in that routine.

    10. Never exercise to lose weight and never exercise to the point of exhaustion. It’s dangerous for you and your baby.

    11. Take regularly scheduled rest breaks during your workout routine. Every 10-20 minutes, stop, drink some water and rest until you feel you are ready to do the next exercise. Listen to you body and don’t overdo it.

    12. Schedule in warm-up, stretching and cool down times during your workout routine.

    13. Avoid contact sports all together. Your baby is at risk, and so are you.

    14. Be cautious when doing heavy weight training. Any weight training should be done with light weights and for the purpose of toning. Never strain your back when lifting weights and maintain a strong core and good form to prevent injury.

    15. Avoid all exercise that involves lying flat on your belly (this is especially important for the second and third trimester). Ask your doctor if it is okay for you to do during the first trimester.

    What Exercises Should Be Avoided During Pregnancy

    When choosing an exercise program during pregnancy, there are some important factors that you need to remember so that you don’t increase your risk of injury to yourself or any harm to your baby.

    Women have sudden and dramatic increases in estrogen and progesterone during pregnancy.

    A woman will produce more estrogen during one pregnancy than throughout her entire life when not pregnant.

    During pregnancy, another hormone called relaxin also increases. This helps loosen your joints to help prepare your body (especially your pelvis) for delivery.

    Because of these hormonal fluctuations during pregnancy, exercise is more difficult and you are more prone to injury.

    Ligaments become looser during pregnancy, and it increases the risk of sprains and strains throughout your body.

    So which exercises should you avoid?

    Twisting

    High impact

    Exercises lying on your belly

    Exercise in high heat environments

    High impact dancing

    Weight loss workouts

    Contact sports

    Fall risk exercises/activities

    Heavy Weight Lifting

    Exercise that involves holding your breath

    Traditional Abdominal Exercises

    Can You Do Squats During Pregnancy

    You sure can! In fact, I absolutely love prescribing squats to women who are pregnant. There are a lot of benefits from doing squats throughout the entire 9 months of pregnancy.

    Performing a squat, the correct way, with proper technique, will help to open up the pelvis. This is so important for childbirth. The motion of squatting mixed with gravity tugging down against you will help your baby to drop down as your pelvis begins to open.

    There are various ways to perform squats, but my favorite way to perform a squat while pregnant is to do a wall sit squat against a physio ball. It’s comfortable on the back and is easier to perform. The physio ball helps you to maintain the correct form throughout the movement. 

    This exercise is by far the best exercise to help prepare for childbirth so be sure to do this all the way leading up to your due date. 

     

    How To Perform A Squat While Pregnant

     

    To perform squats safely while pregnant follow these steps:

    1. Place physio ball behind your back and against a blank wall

    2. Legs are positioned about shoulder width apart and slightly out in front of you about 6 inches.

    3. Slowly and gradually squat down while maintaining a flat back up against the ball. Your body will roll down as the ball rolls.

    4. When you squat, if your knees go way over top of/in front of your toes, you’re not performing the squat correctly and you need to position your feet further away from the wall. Your knees should only maximally go right over your feet/toes and not past them.

    5. Lower your body, and only go as far down as your body is comfortable doing. Do not go too deep into the squat where you are unable to get back up. Have a sturdy chair nearby if you need support and balance assistance. 

    6. Do not strain, and do not hold your breath.

    7. Hold the squat for 2 seconds. Optional: to progress, hold the squat for 5-10 seconds.

    8. Push through your feet and straighten your knees as your back begins to roll on the ball and you return back to starting position (standing). Slowly and smoothly return to the starting position.

    9. Repeat 5-10 reps x 1-3 sets. Perform 3-6 days a week.

    Conclusion

    Now that you know how important exercise is during pregnancy, the benefits, safety measures to take into consideration and guidelines for all three trimesters, it’s time to start a workout routine. 

    Here I have created a Total Body Prenatal workout routine that is specifically designed with safety in mind. Physical therapists recommend these exercises to women who are pregnant throughout all three trimesters. They are safe and effective.

    Don’t just start any random exercise routine, be sure to choose only exercises that are safe during pregnancy. There’s as laundry list of workouts that are to be avoided now that you are pregnant so take caution when watching YouTube videos randomly online, and be sure to get your doctor’s approval before starting a new routine.
