Why “Don’t Lift Heavy While Pregnant” Isn’t Evidence-Based: A Look at New Research
The Myth That Won’t Die
“Don’t lift heavy while pregnant.”
It’s advice pregnant women hear constantly — sometimes from well-meaning providers, sometimes from outdated guidelines.
But new evidence shows a very different story.
The Research Says Something Else Entirely
Recent findings show resistance training lowers the risk of:
Gestational hypertension (~60%)
Gestational diabetes (~40%)
Perinatal mood disorders (~50%)
Macrosomia (~30%)
Now here’s the twist:
These benefits came from studies using extremely conservative loading.
We’re talking:
Bands
1–2 kg dumbbells
No weights above 20 lbs
Minimal to no progression
And yet — outcomes still improved.
So What’s the Actual Issue?
The issue isn’t pregnant women lifting heavy.
The issue is:
✘ Poor reporting
✘ Under-dosing
✘ Fear-based guidelines
✘ Minimal real strength stimulus
Strength training doesn’t become dangerous because someone becomes pregnant.
But our recommendations often become unnecessarily restrictive.
What This Research Actually Supports
✓ Progressive loading is safe when symptoms are monitored
✓ Strength work supports metabolic and cardiovascular health
✓ Movement confidence and mental wellbeing improve
✓ Resistance training should be personalized, NOT minimized
Pregnancy isn’t a fragile state.
It’s a physiologically capable one.
What Needs to Change
We need guidelines that match real women’s needs:
More research on appropriate loading
Better reporting standards
Clearer intensity guidance
Programs that treat pregnancy as a place for strength, not fear
