When you’re trying to conceive, it’s only natural that you’d want to “prime” your body to increase your chances of welcoming a mini-you (or multiple mini-yous — we know, it's not a word; forgive us 🫣) into your family.

And one of the first things to go would 100% be those psychological stressors.

After all, research shows that cortisol, the stress hormone, can really throw your hormonal levels out of whack, preventing ovulation, which is the release of an egg from one of the ovaries.

OK, this means you should learn to get better at setting firm boundaries (e.g., say no to working overtime or soul-sucking social engagements), meditating, and catching up with loved ones.

But … aren’t we all forgetting something?

Psychological stressors aren’t the only cortisol-spiking culprits around. Case in point: physical activity.

Yep, just so you know, the body perceives exercise as a form of stress.

So, what does this mean? Should you stop exercising while trying to conceive?

Exercising while trying to conceive is generally a good idea

In most cases, the answer to that question is a no. Despite:

• The media's typical portrayal of exercise being dangerous for those TTC and/or pregnant, and
• (Probably) your own fears of disrupting your hormonal levels or upsetting the blastocyst’s attempt to implant onto your endometrium (i.e., the lining of your uterus)

… a large body of research shows that exercising while trying to conceive is a good idea.

It could help promote regular ovulation, which increases your chances of getting pregnant faster within a set period. (This is because no egg = 0% chance of fertilization.)

Take this study published in Obstetrics & Gynecology, for instance.

The researchers found that women without a history of infertility who got at least 30 minutes of physical activity daily had a 69% lower risk of ovulatory disorder fertility.

There’s also evidence showing that women with polycystic ovary syndrome (PCOS) and irregular cycles who lose 5% to 10% of their body weight — often through a combination of physical activity and healthier lifestyle changes — often see a positive impact on ovulation.

But, of course, like almost all things in life, there’s a catch. We did say “in most cases”.

Two studies (a 2012 one, plus a 2016 one, both published in Fertility and Sterility) have found that vigorous exercise may reduce your chances of getting pregnant.

Ah, but what’s considered “vigorous” exercise when you’re TTC?

How would you quantify “vigorous”?

And against which benchmarks, specifically? Is it:

• Frequency of exercising while trying to conceive, or
• Intensity of exercising while trying to conceive, or
• Particular type(s) of workouts, or
• Something else altogether?

TBH, the researchers in the two studies mentioned above (the 2012 and 2016 ones) did offer a definition: >5 hours of high-intensity exercise per week.

But if you found that massively unhelpful (because what’s “high intensity”?), these may put you in a better mood:

Also, while >5 hours of high-intensity exercise per week is an excellent general guideline for what's considered "vigorous" (and "bad" if you're TTC), we do need to account for individuality.

To illustrate this, let's say a professional female athlete who's used to training 3 hours a day, 5 days a week, is trying to conceive.

What are the chances that 6 hours of high-intensity weekly exercise would be "too vigorous" for her when trying to conceive?

The point here is this: consider your “normal” or baseline fitness when trying to determine what’s too vigorous for you when TTC.

That said, here are a few tell-tale signs you’re exercising too much (or too hard) you may find helpful to keep in mind; you:

• Keep getting sick
• Can’t seem to recover from DOMs
• Struggle with progressive overloading
• Lose motivation to work out
• Stop getting your period

Yep, those are all signs of exercise burnout.

What to note if you’re using assisted reproductive technologies

Exercising while trying to conceive (we’re talking an appropriate amount in terms of frequency and intensity) is generally recommended … unless you’re using assisted reproductive technologies (ART) involving hormonal treatments.

Specifically:

• Medicated intrauterine insemination (IUI), and
• In vitro fertilization (IVF)

Note: this isn't to say that exercise would impede the blastocyst from successfully implanting into the endometrium.

In fact, there's research to suggest otherwise.

Instead, the risk here is that because hormonal injections stimulate the development of multiple follicles (tiny, fluid-filled sacs in the ovary that contain an immature egg each), the ovaries can sometimes enlarge till they rival the size of a grapefruit!

So, given their size, physical activity could increase the chances of ovarian torsion, where the ovary twists around its stalk.

This is a medical emergency.

Important disclaimer: regardless of whether you’re undergoing ART, it’s always, always, still a good idea to have a trusted healthcare provider clear you for exercise while trying to conceive.

They’ll have the necessary knowledge and expertise to screen your medical history for potential concerns.
