You have been lifting for a while, or you are thinking about starting, and somewhere along the way you read that heavy lifting is hard on the pelvic floor. Maybe a friend stopped deadlifting after a few bladder leaks. Maybe you noticed a heaviness or a dribble yourself and wondered whether the barbell was to blame.
It is a fair question, and the honest answer is more nuanced than either "lifting damages your pelvic floor" or "there is nothing to worry about." The pelvic floor is the group of muscles and connective tissue that sits like a hammock at the base of your pelvis. It helps support the bladder, bowel and uterus, and it helps keep you continent (able to hold urine and stool until you choose to go).
This post looks at what research suggests about heavy lifting and pelvic floor symptoms, where the evidence is thin, and what many people find helpful. It is written for women and people with female anatomy, and it is meant to inform your decisions, not make them for you.
What Does the Research Say About Lifting and Pelvic Floor Symptoms?
Most of the research on this question is observational. Researchers ask lifters about their symptoms, then look for patterns. That kind of design can show that two things go together, but it cannot show that one causes the other.
A 2025 systematic review of studies in female powerlifters and weightlifters (a systematic review gathers and appraises all the studies it can find on a question) reported that urinary leakage was common in these groups. Reported rates varied quite a bit between studies, and in several of them close to half of the participants described some leakage. The review also noted that leaks seemed to show up more with certain lifts, such as deadlifts and squats, and with heavier loads, higher repetitions and competition settings.
Two cautions go with that. First, the studies were small and mostly relied on self-reported symptoms. Second, factors like age, number of vaginal births and body mass index also appeared to matter, so lifting is unlikely to be the whole story.
It is also worth saying what "common" means here. Something can be common among people who train hard and still not be inevitable, or a sign that your body is failing. Leaking when you lift, run or jump is a common experience, and it is also something many people want to change. Both can be true.
Is the Prolapse Worry Justified?
Pelvic organ prolapse is when one of the pelvic organs, such as the bladder or uterus, settles lower into the vaginal canal than before. Many people with prolapse have no symptoms at all, and when symptoms do occur they can include a feeling of heaviness, a bulge, or pressure that is worse at the end of the day.
A 2020 cross-sectional survey (a snapshot of many people at one point in time) asked physically active women who lift heavy weights about prolapse symptoms. The authors reported that heavy lifters did not have a higher prevalence of symptoms than women lifting lighter loads, and some lighter lifters reported more. This is reassuring, but it is a single survey based on self-report, and it cannot tell us about what happens to any one person.
So the current picture is mixed. Urinary leakage appears to be more commonly reported in lifting populations, while the prolapse research does not show a clear link to heavy loads. If you want to read more about prolapse in general, we have a separate page on it that goes into much more depth.
What About Holding Your Breath When You Lift?
You may have heard of the Valsalva manoeuvre: taking a breath, holding it and bracing against a closed airway. It raises pressure inside the abdomen (intra-abdominal pressure), which stiffens the trunk. Many lifters do it automatically as the weight gets heavy.
For years, the common advice was to avoid it, partly because higher pressure was assumed to push down on the pelvic floor. Recent thinking is less certain. A 2024 clinical commentary from pelvic health physiotherapists in the UK argued that avoiding the manoeuvre entirely is not realistic at very heavy loads, and that it may make more sense to respond to symptoms than to ban a technique. That commentary is expert opinion rather than trial evidence, and you should read it that way.
Pressure-measurement research points in a similar direction. A small study of women using a vaginal pressure sensor found that straining on the toilet or coughing could generate higher pressures than many exercises did. The authors suggested that guidance could be more individualized than blanket rules. These were small studies, though, and they measure pressure, not whether anyone developed symptoms.
Here is the part that is genuinely unknown: it is still unclear why two lifters with similar training can have very different pelvic floor experiences. Body, birth history, hormones, connective tissue, sleep, stress and coughing or constipation habits may all play a part. Nobody has a tidy answer yet.
What Can You Adjust if You Notice Symptoms?
What follows draws on clinical experience and general understanding, not on a single trial. Treat it as ideas to try, and set aside anything that doesn't suit you.
Look at the lift that bothers you most. If leaking tends to happen at the top of a heavy squat, that is information. Some people find that dropping the load by a modest amount for a few weeks, or trimming the number of repetitions in a set, changes how things feel. It is not a punishment, and many people return to heavier weights later.
Experiment with breathing. Instead of holding a big breath for the whole rep, some lifters try exhaling gently through the hardest part of the movement, or taking a breath at the top and letting a little air out on the way up. Others find they prefer a held breath for one-rep efforts but a softer approach for sets of eight. There is no single right way, and it may take a few weeks of trial and error.
Think about the whole pelvic floor, not just squeezing. Pelvic floor muscle training means deliberately contracting and relaxing those muscles to build strength and coordination. A 2018 Cochrane review (Cochrane reviews are widely regarded as rigorous summaries of the evidence) reported that pelvic floor muscle training was associated with improvement in stress urinary incontinence, which is leakage with effort or pressure, such as coughing or lifting. Most of that research was in general populations, not in lifters, so how well it applies to someone squatting heavy is less certain.
Some people also find that their pelvic floor is already tense. In that case, working on relaxation, and being able to let go fully between reps, matters as much as squeezing. A pelvic health physiotherapist can help work out which applies to you.
Notice the other pressure points in your day. Chronic coughing, long stretches of straining with constipation, and rushing a full bladder are all things that can affect the pelvic floor too. A lift might be the loudest moment, but not the only one.
When Is It Worth Getting Assessed?
Not every leak or twinge needs treatment. A single drop after a very hard set, in a person who is otherwise symptom-free and not bothered, may simply be something to watch. Variation from week to week is common, particularly around the menstrual cycle, after illness, or during poor sleep.
It becomes worth a conversation with a healthcare provider when symptoms are bothering you, are getting more frequent, or are changing what you do. Some examples: skipping squats you used to enjoy, wearing pads to every session, planning your day around bathrooms, or feeling a persistent bulge or heaviness. Pain with lifting, pain with sex, or blood in the urine or stool are reasons to speak with a physician or nurse practitioner promptly, because they may need medical assessment that is outside physiotherapy.
An international group of experts developed a screening tool for female athletes, known as PFD-SENTINEL, using a structured consensus process (the Delphi method, where experts rate statements over several rounds until they largely agree). Its authors suggested that even one of a short list of symptoms could be reason to seek specialist care. The tool is still being validated, so think of it as one reference point, not a rule.
What Does Pelvic Health Physiotherapy Involve for a Lifter?
A pelvic health physiotherapist is a registered physiotherapist with extra training in the pelvic floor. An assessment usually starts with a conversation about your history, your training and what you want to keep doing. With your consent, it may include an assessment of the pelvic floor muscles, which can be done externally or internally. You can ask for alternatives, pause, or stop at any point.
A common aim is to keep you lifting, not to take you out of the gym. That might include a graded plan, changes to technique and breathing, strengthening of the hips and trunk, and coaching on how to relax the pelvic floor. Physiotherapy is one option among several. Depending on your symptoms, your family physician, a midwife, a nurse practitioner, or a urogynecologist (a physician who specializes in pelvic floor conditions) might also be involved.
At Core Connection, care takes place in your home, whether you live in Victoria, the Cowichan Valley, North Vancouver or West Vancouver. Some lifters find it easier to talk about this sort of thing in a familiar space, and having the barbell or the kettlebell nearby can help, because we can look at the movement that bothers you in the room where you actually train.
The Balanced Takeaway
Heavy lifting and pelvic floor symptoms are associated in some research, particularly for urinary leakage, but the evidence is observational, the studies are small, and the prolapse findings are mixed. Lifting is also linked with many benefits, including strength and bone health, so the question is rarely whether to lift at all.
If your body is giving you information, such as leaks, heaviness or a sense that something is off, you can treat it as a puzzle to work through, not a verdict. Small adjustments to load, breath and recovery help some people, and an assessment with a pelvic health physiotherapist is one option available to you if you would like support.
