3 Common Myths of Pregnancy and Strength Training

There’s no shortage of myths and conflicting information when it comes to pregnancy and exercise. It’s no wonder women often feel confused about what’s appropriate exercise-wise during pregnancy.

Many of the misconceptions about pregnancy and exercise lead women to be overly cautious during pregnancy (sometimes to the point of not exercising at all), and overly relaxed about post-pregnancy exercise, jumping back into intense exercise too quickly.

For years, pregnant women were advised to stick to nothing but walking, and maybe some gentle stretching or yoga. Luckily, as more research comes out about the benefits of moderate to vigorous exercise during pregnancy, the tide is starting to turn.

In fact, the American College of Sports Medicine (ACSM) and The American College of Obstetricians and Gynecologists (ACOG) list the following benefits to exercise for pregnant women:1 2

    • Prevents excessive weight gain during pregnancy
    • Reduces risk of gestational diabetes
    • Decreases risk of high blood pressure associated to pregnancy (preeclampsia)
    • Decreases postpartum recovery time
    • Decreases risk of low back pain
    • Decreases severity of low back pain
    • Decreases risk of urinary incontinence
    • Prevents / improves symptoms of depression
    • Maintains physical fitness
    • Prevents postpartum weight retention
    • May reduce the risk of cesarean delivery

As you can see, exercise during pregnancy is very beneficial, and below I’m going to tackle three of the most common myths regarding strength training and pregnancy.

1. You can’t start strength training for the first time during pregnancy.

The often-repeated advice that many women receive to “keep doing what you were doing before you got pregnant and avoid doing anything new,” is not always accurate or helpful.3

You absolutely can start strength training in pregnancy as long as you’re cleared by your doctor for exercise. In fact, ACOG goes so far as to recommend, “Women with uncomplicated pregnancies should be encouraged to engage in aerobic and strength conditioning exercises before, during, and after pregnancy.”4

The catch here is that, while someone who was training at a moderate to high intensity before becoming pregnant can continue training at that intensity throughout her pregnancy (provided there are no health concerns), someone else who was sedentary before becoming pregnant should only be exercising at a low to moderate intensity throughout her pregnancy.2

2. You can’t lie on your back after 16 weeks of pregnancy.

This “myth” is one of the most frequently cited, and with good reason, because it’s not as much of a myth as it is just plain unclear. According to the Girls Gone Strong Pre- & Postnatal Coaching Certification textbook:

“In the past, physicians have advised women to not to lie on their backs because the weight of the baby could press on, and block, the mother’s vena cava, the main vein that carries blood back to the heart from the lower body, and some recommendations say that after week 16, a woman should avoid lying flat on her back for long periods of time.4

However, ‘long periods of time’ is not clearly defined, and 2006 research published in BJOG, shows that uterine blood flow decreases when women lie on their backs, although during supine exercise, the decrease is about half of what it is during supine rest.5

Current guidelines from Sports Medicine Australia suggest avoiding exercise in the supine position after 28 weeks.6 However, more recently, some research has stated that as long as a woman feels OK while lying on her back, and she doesn’t feel lightheaded or nauseated, tingling in the legs, general discomfort, and her breathing is not impaired during or after the bout of exercise or stretching, she should be fine to lie on her back.4

You can see that there are some differences depending on which guidelines you read. If you do perform supine exercises, or program them for a client, check in regularly to make sure none of the symptoms listed above appears.

These guidelines seem to change quite frequently as the science changes and we learn more, so be sure to check them regularly and stay informed. Most women will probably be fine, especially if they monitor how they feel, but if you want to be ultra safe, you can avoid the supine position after 24-28 weeks or work at a 15 percent incline.”

Body positivity is unlearning the idea that only certain bodies are worth acceptance and praise, and instead recognizing that all bodies are equally valuable. It’s deciding what feels good and healthy for you personally, and letting other people do so for themselves. It’s understanding that you deserve to live in your body without receiving the prejudice of others (whether that means rude comments, reduced economic opportunity, inadequate health care, or something else), and working toward a world where no one’s body is the target of such bias. ⠀⠀⠀⠀⠀⠀⠀ Accepting and loving your body doesn’t mean your outside is the most important part about you, or that you cease working to improve your nonphysical qualities. For me, adopting body-positive ideals actually freed up my mind to learn more about what I want out of life, to open myself up more to others, and to work on gaining knowledge and skills I hadn’t gotten around to when I was all-consumed with the size of my thighs. ⠀⠀⠀⠀⠀⠀⠀ Which is not to suggest that embracing your own physicality is where the journey ends, because true body positivity still means working toward the EMPOWERMENT (emotional, economic, and beyond) OF OTHERS. Still, it’s worth acknowledging that loving your own body doesn’t make you selfish.

3. Leaking urine during exercise is normal when you’re pregnant.

Involuntary leakage of urine (i.e. urinary incontinence) at any point in time, while common, is not “normal.” The two most commonly described conditions are stress urinary incontinence (SUI) or urge urinary incontinence (UUI). Stress urinary incontinence is defined as a “complaint of involuntary loss of urine on effort or physical exertion (e.g. sporting activities), or on sneezing or coughing.”7 Examples of this might be leaking of urine when doing a box jump or jumping rope.

Just how common is incontinence during pregnancy? Some research suggests that around 48 percent of pregnant women who have never given birth have signs of incontinence by week 308. This rate increases to around 67 percent for those who have given birth before.

For most women, this is stress urinary incontinence and results in a few drops of urine only once a week. For others, this is a significant symptom that affects quality of life. The good news is that you don’t have to live with urinary incontinence. There are pelvic health physiotherapists who specialize in helping women just like you find relief from incontinence.

And even if your incontinence is mild and doesn’t affect your life? It’s still important to get evaluated by a pelvic health physio. Incontinence is a sign that something in your core “system” is breaking down, and your pelvic floor happens to be where the breakdown is showing up. Being evaluated by a qualified physiotherapist can help reduce your risk of future pelvic floor dysfunction like pelvic pain, dyspareunia (i.e. pain with sex), and pelvic organ prolapse.

Whether you’re new to strength training during pregnancy or a seasoned veteran, keep these three myths in mind so you can have a safe, strong, happy, and healthy pregnancy and postpartum experience.
