You leak a little when you deadlift, or you feel a heaviness after a big set, and someone (a well-meaning friend, a forum, sometimes even a health professional) tells you to stop lifting heavy altogether. It’s some of the most common advice given to women with pelvic floor symptoms. It’s also, for most women, the wrong advice.
Why This Matters to You
Blanket avoidance doesn’t fix what’s actually going on, it just removes something you might genuinely value, whether that’s strength training, running, or picking up your own kids without thinking twice. Over time, stepping back from all loaded movement also means losing muscle, bone density, and metabolic health, exactly the things that matter most through your 30s, 40s and beyond. This year’s Women’s Health Week theme is “do it anyway,” and this is a good example of where the fear of a symptom is often doing more damage than the activity itself.
Why “Just Stop Lifting” Became the Default Advice
The instinct behind this advice makes sense on the surface. Heavy lifting increases intra-abdominal pressure, and pelvic organ prolapse and stress incontinence are both, in part, pressure-related conditions. So the logic went: less pressure, fewer symptoms, therefore less lifting.
The problem is that this treats the barbell as the cause, when in most cases it’s more accurate to say the pelvic floor’s ability to manage that pressure is the actual issue. Removing the load doesn’t fix that coordination gap, it just avoids testing it.
What’s Actually Happening When You Leak Under Load
Think of your trunk under load like a pressure cooker. The diaphragm sits on top, the deep abdominal muscles wrap around the sides, and the pelvic floor forms the base. When all of them coordinate well under load, pressure is distributed and contained. When the pelvic floor is weak, poorly timed, or not coordinating with the breath, pressure escapes downward instead, and that’s what shows up as leaking, heaviness, or a bulging sensation.
This is a coordination and capacity issue, not simply a “the weight was too heavy” issue. Two women lifting the exact same weight can have completely different outcomes, depending on how well that system is working underneath.
Does Heavy Lifting Actually Damage the Pelvic Floor? What the Evidence Says
For most women, no. Structured, progressively loaded resistance training has not been shown to worsen pelvic floor symptoms in the general population, and appropriately coached strength training is now widely considered safe, and often therapeutic, for stress incontinence.
The more honest answer sits in the caveats. Evidence specifically examining heavy or maximal lifting in women with a diagnosed pelvic organ prolapse is more limited than the evidence for general postpartum return to exercise, and this remains an area where research is still catching up to practice. That doesn’t mean avoid lifting, it means this is exactly the group who benefits most from an individualised assessment rather than either blanket avoidance or a generic “just lift” approach.
Correcting the Myth: It’s the Strategy, Not the Weight
The actual fix usually isn’t lifting lighter forever, it’s rebuilding the coordination between breath, deep core, and pelvic floor, then progressively reloading from there. Breath-holding through a lift (a hard Valsalva without any pelvic floor engagement) is a genuinely different pressure strategy to a coached exhale-on-effort with pelvic floor coactivation, even at the exact same weight on the bar.
This is why two people can be told completely different things by different professionals and both be right, because the advice depends on what’s actually happening in that person’s system, not on the number on the bar.
What This Looks Like in Practice
For most women working through pelvic floor symptoms and strength training, this generally involves:
- Starting with pelvic floor and deep core coordination at lower loads, focusing on timing and breath strategy rather than just strength
- Progressively reintroducing heavier loads once that coordination is reliable under fatigue, not just when fresh
- Adjusting technique cues (exhale on exertion, avoiding breath-holding) rather than removing the lift entirely
- Co-managing with a pelvic health physiotherapist where symptoms are more significant, such as diagnosed prolapse, since pelvic floor assessment sits within their specific scope
This is general guidance, not a substitute for individual assessment, particularly if you have a diagnosed prolapse or persistent symptoms that haven’t improved with general strength training alone.
Where an Exercise Physiologist Fits In
An Accredited Exercise Physiologist can build the strength side of this properly: progressive loading, technique coaching, and programming that respects where your pelvic floor is at right now without permanently benching heavy lifting from your life. Where needed, we work alongside a pelvic health physiotherapist, rather than instead of one, so the coordination work and the strength work are actually talking to each other.
Avoiding heavy lifting isn’t protecting your pelvic floor, it’s usually just avoiding the problem. With the right strategy, most women can keep training the way they want to.
If you’ve been told to stop lifting heavy because of pelvic floor symptoms and want a second, evidence-based opinion, get in touch with The Active Studio to book a Women’s Health assessment with one of our Accredited Exercise Physiologists.
