To Crossfit or not to Crossfit: Part 2

“Meg the Midwife's” suggestions for working out ‘Paleo-styles’ during pregnancy



1- Listen. Listen to your body’s wisdom…really listen…if you are unable to listen then stop doing crossfit. This sounds harsh but it’s important. There are so many of us  “A” types (I totally include myself in this group) running around doing burpees and pull-ups when pregnant. The name of the game during pregnancy is to grow a new life, not to expose a six-pack or set a new PR. Your healthy baby and chilled out body is your new PR. So please, if it hurts, don’t do it. If you’re really tired that day, take a break. Do some light yoga or meditate; you’re doing lots of hard work just growing a new life. This is especially important in the first trimester when your placenta is embedding itself into your uterine wall. As the placenta becomes established, it anchors itself with spiral arteries that connect it directly into your circulation. These arteries supply your baby with oxygen and nutrients. If your body is constantly moving blood away from the uterus to fuel your muscles for a 'Fran' workout , these vessels may not develop in the most optimal way. The take away message: A healthy placenta equals a healthy baby. 

2- Nourish your mind, not just your body: Ask yourself this question every day...."Is my workout nourishing my body AND mind ?" Are you stressed?  If so, take a break. Prolonged fetal exposure to high levels of maternal cortisol (the stress hormone) have been shown to affect a child’s IQ and cognitive performance. High levels of stress may also contribute to low progesterone levels. Low progesterone in the first trimester puts you at risk for miscarriage. Stefani Ruper from the Paleo for Women has a great post about stress induced low progesterone that's worth checking out! 

3-Scale: Be sure to properly scale your workouts. Check out crossfit mom for proper scaling suggestions. Join a crossfit mom’s group. No class at your gym, ask if you can start one! It’s a great way to connect with other pregnant and postpartum mom’s in a supportive environment. Balance your crossfit workouts with lots of long walks or hikes in nature. Being in nature has been shown to improve mood and overall wellbeing. Check out Mark's post here for more reasons why we should spend more time in nature. 

4- Chill out: Try to incorporate some sort of relaxation, meditation and muscle relaxing component to your workouts. Gentle restorative prenatal yoga and hypnobirthing meditations are great choices. Practice releasing, rather than engaging your pelvic floor muscles. The Spinning Babies site is one I recommend to many of my clients. The side-lying exercise found here, can be especially helpful if you're a crossfit athlete, runner or cyclist and may have some muscular imbalances in your pelvic floor.

5- Refuel:  If you're working out be sure to refuel your body with lots of filtered water (I like this filtration system) and healthy nutrient dense paleo or primal meals.

A sprinkle of daily meditation 

Remember, these are all just suggestions based on what I’ve learned from hundreds of women. You are your own best coach, so tap into your body’s inner wisdom and connect with what it needs. Happy trails!


To crossfit or not to crossfit? What's a pregnant woman to do? Part 1

A recent article in Paleo Magazine got me thinking about crossfit and other intense workouts during pregnancy. I’ve worked in many different communities and seen all sorts of variations in how women exercise. In the busy mountain town of Canmore Alberta,  I often had a caseload of Olympic level athletes, professional climbers, mountain guides and all sorts of fit active trail runners and crossfit gals. My mission in that town was to help women learn to SLOW DOWN and scale. This community had anecdotally higher rates of IUGR (intrauterine growth restriction) and difficult births. It was my theory that some, not all, but some, babies would become malpositioned, as a result of tight pelvic floor/hip muscles that just wouldn’t release. Many mama's also had a hard time letting go and allowing their minds to ‘relax’ so their bodies be primal and labour. 


My heart goes out to all my friends in Canmore who were devastated by flooding this week. Let the light shine and bring you hope as  the massive clean up begins.

My heart goes out to all my friends in Canmore who were devastated by flooding this week. Let the light shine and bring you hope as  the massive clean up begins.

Today, I work with an urban population of ‘side-walk walkers’ and immigrant women. For many of these women, activity isn’t a valued part of their culture and they simply cannot afford the time to dedicate to exercise. Here, I see much higher rates of gestational diabetes and obesity. In this community, my mission is to get women moving.

So what’s a Paleo gal to do? Where’s the middle ground? If you’re a paleo-ista mama to be, what is the right thing to do when you are newly pregnant? Is crossfit okay? 


The honest truth is that we don’t really have any conclusive evidence to support or discourage vigorous exercise in pregnancy. Doing studies on pregnant women is unethical and as a result the AOCG and SOGC both give very vague guidelines in regards to exercise in pregnancy. The crossfit mom’s website does have a link to a study that looked at birth outcomes of 2 crossfit gals. This being said, a sample size of 2 isn’t research we can base a solid set of recommendations from. So what do we know for sure?

We know:

  • Women who stay fit and active during pregnancy are healthier, have easier labours, less chance of obstetrical complications and quicker recoveries.


  • Women who exercise report higher energy and lighter mood.


  • Women who stay active tend to not gain too much weight in pregnancy, which has been shown to increase the risk of complications.


  • Women report labour as being less painful and ‘easier’


  • So let’s start exploring this topic a bit more with some basic biology. Here’s what happens when a woman becomes pregnant.

Warning…this is about to get a bit nerdy.

Heart Rate:

As your blood plasma volume increases, the amount of blood the heart has to pump through your body, also increases. This causes a rise in your resting heart rate.


Pregnant women have a higher oxygen demand than their non-pregnant counterparts. Remember, you’re breathing for two! With mild exertion there is an increase in the number of breaths and amount of oxygen required to meet your greater demands. As exercise increases to moderate and maximal levels, however, you pregnant women do a funny thing. Your respiratory frequency and maximal oxygen consumption actually begin to decrease!  Say what?? The oxygen demand at high levels of activity (e.g. a hard WOD) appears to overwhelm the system. This may be partially due to the obstructive effect of enlarged uterus on the diaphragm making it mechanically difficult to get in deeper breaths. Theoretically, this could increase the risk of hypoxia to the baby. If done once or twice, while sprinting from a sabertooth tiger for instance, it’s likely okay, but theoretically, if done 4-5 times per week throughout the pregnancy, it could lend significant effects on your placental and fetal development.

Temperature Change:

Pregnant women are well known for being furnaces! That’s because there is a lot of metabolic activity going on inside that bountiful body. As you exercise, metabolism is further increased, resulting in higher core temperatures. Ensuring that you don’t overheat or dehydrate during exercise becomes critical in order to avoid fetal mid-line fetal defects in the first trimester and central nervous system effects in the second and third.  In my experience, mild dehydration can predispose you to uterine contractions and may put you at risk for preterm labour, not to mention make you feel terrible, so please drink up!

Musculoskeletal Change:

The chilled out hormone relaxin causes your joints and ligaments to become lax…get it… ‘relaxin’. This can predispose you to everything from tearing an ACL to misaligning your SI joints to spraining an ankle. Proper form when lifting and avoiding any sudden lateral movements becomes critical. With each subsequent pregnancy, your levels of relaxin appear to exert their effects earlier in pregnancy, so take care! Your growing belly can also send you a bit off kilter, which is why pregnant women are notorious for falling down or bumping into things. Watch your balance and your belly!

I don’t want to be an exercise ‘Debbie downer’ of sorts but let’s take a Primal approach... what a cavegirl would do?

She would:

- Walk a lot

- Lift and carry children

- Carrying water

- Prepare meals and gather berries (often while squatting)

Would they be doing pull-ups, burpees and clean and jerks? I’m not so sure of that.
