One of the most common questions we hear from women is:
"Is it safe to keep strength training while I'm pregnant?"
For years, the advice around pregnancy and exercise was often very cautious.
Don't lift too heavy.
Don't push yourself.
Take it easy.
And whilst that advice was always well-intentioned, much of it wasn't based on strong evidence.
Now, new research from the University of Alberta, published in the British Journal of Sports Medicine in 2025, is helping change the conversation.
And the findings are encouraging.
The Old Advice: Better Safe Than Sorry
Historically, pregnancy was often treated as a time to avoid anything that looked physically demanding.
Many women were encouraged to:
- Stop lifting weights
- Reduce training intensity
- Avoid challenging exercises
- Play it safe
The concern was understandable.
Researchers worried that heavy lifting might:
- Reduce blood flow to the baby
- Increase blood pressure too much
- Put excessive stress on the body
The problem?
Most of these concerns were based on theory rather than direct evidence.
What The New Study Found
Researchers wanted to answer a simple question:
What actually happens when trained women lift heavy during pregnancy?
They monitored pregnant women performing exercises such as:
- Squats
- Deadlifts
- Bench press
At relatively high intensities.
Importantly, they didn't just look at the mother.
They measured how the baby responded too.
And the results surprised many people.
The researchers found:
- No signs of fetal distress
- Stable fetal heart rates
- Normal blood flow patterns
- Good tolerance from both mother and baby
In short:
The body appeared remarkably capable of handling strength training.
Why This Matters
This is important because it challenges a belief many women have carried for years:
"Pregnancy means I need to stop being strong."
The reality is often very different.
For many women, continuing to strength train can help them:
- Maintain muscle mass
- Reduce aches and pains
- Improve posture
- Support healthy weight gain
- Maintain energy levels
- Prepare for the physical demands of motherhood
After all, pregnancy itself is physically demanding.
Carrying a growing baby for months requires strength.
Lifting a car seat requires strength.
Carrying a toddler requires strength.
Recovery after birth requires strength.
Pregnancy Is Not Fragility
One of the biggest shifts happening in women's health right now is moving away from the idea that pregnancy automatically makes women fragile.
Pregnancy is not an injury.
It's an adaptation.
The female body is designed to adapt to extraordinary demands.
That doesn't mean ignoring symptoms.
And it doesn't mean every woman should train the same way.
But it does mean we should stop assuming that strength training is inherently dangerous.
The Benefits We Often See
Many pregnant women arrive worried that they'll lose all their fitness.
In reality, those who continue training appropriately often report:
- Better energy
- Less back pain
- Improved confidence
- Better mobility
- Easier return to exercise after birth
Strength training can also provide something incredibly valuable during pregnancy:
A sense of normality.
A reminder that your body is capable.
Not broken.
Not fragile.
Capable.
Does This Mean Everyone Should Lift Heavy?
Not necessarily.
This is where context matters.
The women in the study were already experienced lifters.
They weren't complete beginners.
And every pregnancy is different.
What is appropriate for one woman may not be appropriate for another.
That's why coaching and medical guidance are important.
The goal isn't to prove how tough you are.
The goal is to stay healthy, strong and confident throughout pregnancy.
How We Approach Pregnancy Training
At House of Styrka, we don't believe pregnancy means stopping.
We believe it means adapting.
That might involve:
- Adjusting exercise selection
- Modifying range of motion
- Managing training volume
- Monitoring fatigue
- Progressing appropriately through each trimester
The focus shifts from performance to preparation.
Preparing for birth.
Preparing for motherhood.
Preparing for recovery.
The Bigger Question
Perhaps the most important question isn't:
"Can pregnant women lift weights?"
It's:
"Why have we spent so long assuming they couldn't?"
The evidence continues to show that movement during pregnancy is not only safe for many women.
It's beneficial.
The Takeaway
If you're pregnant and already strength training, this new research should be reassuring.
Your body is likely more resilient than you've been led to believe.
Strength training can help support:
- Physical health
- Mental wellbeing
- Confidence
- Recovery
- Long-term fitness
The key is training intelligently.
Not avoiding strength altogether.
Because pregnancy isn't the end of your strength journey.
For many women, it's simply a different chapter of it.
