Why Do I Leak When I Run, Jump Or Exercise? Understanding Stress Urinary Incontinence

You go for a run and notice a small amount of urine leakage.

Perhaps it only happens during sprints. Or skipping. Or box jumps.

Maybe you are completely fine through most of your Pilates class but leak when the class includes repeated jumping.

Exercise-related urinary leakage is common, but assessment can help identify the factors contributing to your symptoms.

For some women, it begins during pregnancy or after having a baby. For others, it appears years later. Some first notice it around perimenopause or menopause.

And because urinary leakage is common, many women assume it is simply part of having children, ageing or exercising hard.

Common does not mean something has to be ignored.

Urinary leakage during activities that increase pressure and impact is often described as stress urinary incontinence.

The word “stress” in this context does not mean psychological stress. It refers to situations where increased pressure within the abdomen, such as coughing, sneezing, running, jumping or lifting, contributes to urine leakage.

Pelvic floor function is part of the picture.

But the answer is not always simply: “Do more Kegels.”

What Is Stress Urinary Incontinence?

Stress urinary incontinence is involuntary urine leakage associated with physical effort or exertion, coughing or sneezing.

Someone might experience leakage during running, jumping, skipping, heavy lifting, coughing, sneezing, laughing, changing direction during sport or other high-impact exercise.

The amount can vary significantly.

Some women notice only a few drops. Others experience enough leakage that they begin wearing pads, avoiding certain exercises or planning training around toilet access.

The symptom can have a substantial effect on exercise confidence even when the volume of leakage seems relatively small.

Why Does Running Make Me Leak?

Running creates repeated changes in force and pressure.

Each stride requires the body to manage impact while the trunk, hips and pelvic floor coordinate with breathing and movement.

The pelvic floor contributes to supporting the pelvic organs and maintaining continence.

If the demands of running exceed the system’s current capacity, leakage may occur.

That does not automatically mean your pelvic floor is simply “weak”.

Pelvic floor muscle strength may be relevant, but so can timing, endurance, coordination, impact tolerance and the interaction between the pelvic floor and the rest of the trunk.

Why Do I Leak When I Jump?

Jumping involves rapid force production and landing.

The body has to manage changes in pressure and ground reaction force quickly.

Someone may be completely continent during walking or controlled strength exercises but leak during repeated jumping because the task is faster and more demanding.

Being symptom-free during low-impact exercise does not automatically mean the pelvic floor is prepared for high-impact exercise.

Just as a calf may tolerate walking before it tolerates running, the pelvic floor and surrounding system may tolerate lower-level tasks before repeated impact.

Is It Normal To Leak After Having A Baby?

Urinary leakage is common during pregnancy and after childbirth.

But “common” and “something you should simply accept forever” are not the same thing.

Pregnancy itself changes load through the pelvic floor. Birth may create additional changes depending on the individual experience.

Postnatal recovery also occurs while caring for a baby, sleeping differently, feeding, lifting, carrying and gradually returning to exercise.

If you experience leakage when returning to running or higher-impact activity, Women’s Health Physiotherapy can assess your pelvic floor function and help determine an appropriate rehabilitation pathway.

What Does The Pelvic Floor Actually Do?

The pelvic floor is a group of muscles and connective tissues forming part of the base of the pelvis.

Its functions include contributing to continence, pelvic organ support, sexual function, pressure management and coordination with breathing and trunk activity.

The pelvic floor needs to be capable of both producing force and relaxing appropriately.

This is why pelvic floor rehabilitation is more nuanced than simply squeezing as hard as possible.

Does Leakage Mean My Pelvic Floor Is Weak?

Not necessarily.

Weakness may contribute for some people.

But pelvic floor function also involves coordination, endurance, timing and the ability to respond to changing demands.

Some people may have difficulty generating sufficient contraction. Others may have difficulty relaxing. Some may contract strongly in an assessment but struggle to coordinate that contraction during impact.

This is why blindly prescribing the same pelvic floor exercise to every woman with leakage is not ideal.

Assessment matters.

Should I Just Do Kegels?

Pelvic floor muscle training can be effective for many women experiencing stress urinary incontinence.

But “do your Kegels” is incomplete advice.

A useful pelvic floor programme should consider whether you are contracting the correct muscles, how strongly you can contract, how long you can maintain the contraction, how many repetitions you can perform, whether you can fully relax afterwards, whether you can coordinate the pelvic floor with breathing and movement, and what activities actually provoke your symptoms.

Eventually, rehabilitation should prepare you for the task that matters.

If you leak while running, lying on your back performing isolated contractions may be one component of rehabilitation, but it should not necessarily be the final stage.

Can A Pelvic Floor Be Too Tight?

Yes, pelvic floor muscles can have increased resting activity or difficulty relaxing.

This is one reason more squeezing is not appropriate for every pelvic floor presentation.

Pelvic pain, pain with intercourse, difficulty emptying the bladder or bowel and other symptoms can sometimes coexist with altered pelvic floor muscle activity.

A Women’s Health Physiotherapist can assess whether the priority is strength, relaxation, coordination or another aspect of function.

What Does Breathing Have To Do With The Pelvic Floor?

The diaphragm, abdominal wall and pelvic floor interact as pressure within the trunk changes.

Breathing is therefore relevant to pelvic floor function.

However, there is not one compulsory breathing pattern that must be used during every exercise.

You do not need to become afraid of inhaling at the wrong moment.

Instead, rehabilitation can help you develop strategies appropriate to the task.

During heavier lifting, pressure demands differ from those during gentle Pilates. During running, breathing needs to remain rhythmic and adaptable.

The body should be able to manage different situations rather than depend on one rigid rule.

Should I Exhale Every Time I Lift Something?

Exhaling during exertion can be a useful strategy for some clients and exercises.

But it should not become a universal rule suggesting that holding breath momentarily is inherently dangerous.

The appropriate breathing strategy depends on the load, the individual and the task.

For someone early in pelvic floor rehabilitation, deliberately coordinating an exhale with effort may help them learn pressure-management strategies.

As capacity improves, we want the system to become adaptable.

Does Core Strength Fix Pelvic Floor Leakage?

Not automatically.

The pelvic floor forms part of the broader trunk system, but performing more abdominal exercises does not guarantee continence.

Likewise, having visible abdominal muscles does not tell us how effectively someone

manages pressure or impact.

A comprehensive programme may include trunk and lower-body strengthening because running, jumping and lifting are whole-body tasks.

But we should not replace “weak pelvic floor” with an equally simplistic explanation of “weak core”.

Does Glute Strength Matter?

Hip strength can be relevant to running and lower-body function.

But urinary leakage should not be reduced to “your glutes aren’t firing”.

Someone can have strong glutes and still experience stress urinary incontinence.

Lower-body strength may be included because the person needs adequate force production and control for the activity they want to perform, not because the glutes are assumed to directly switch the pelvic floor on.

Why Can I Lift Weights Without Leaking But Running Makes Me Leak?

Strength training and running create different demands.

A squat or deadlift may involve substantial force, but the movement is relatively predictable.

Running involves repeated impact and rapid cyclical loading.

Someone may therefore tolerate heavy strength training but experience leakage during

running.

The opposite can also occur.

This is why rehabilitation should be specific to the symptom-provoking activity.

Why Does Leakage Get Worse When I Am Tired?

Pelvic floor muscles, like other skeletal muscles, can fatigue.

But whole-body fatigue matters too.

Running technique, breathing, posture and coordination can change as fatigue accumulates.

You may notice no leakage during the first kilometre but symptoms later in the run.

That information is useful.

It suggests that endurance and total task duration may need to be considered rather than assessing only whether you can perform one pelvic floor contraction.

What About Perimenopause And Menopause?

Pelvic floor and urinary symptoms can also become relevant during perimenopause and menopause.

Hormonal changes can influence tissues of the genitourinary system, and women may experience changes in urinary symptoms during this stage of life.

Importantly, leakage should not simply be dismissed as “what happens when you get older”.

Assessment can help identify contributing factors and appropriate management.

For women who also want to maintain muscle, bone and overall physical capacity through menopause, pelvic floor rehabilitation can be integrated into a broader progressive strength programme rather than treated as a completely separate issue.

Should I Stop Running If I Leak?

Not necessarily.

Whether running should be temporarily modified depends on the severity of symptoms, your current capacity and your rehabilitation plan.

For some women, continuing a modified running programme while completing pelvic floor rehabilitation may be appropriate.

Others may benefit from temporarily reducing running volume or impact while building capacity.

The goal does not automatically have to be permanent avoidance.

If running matters to you, rehabilitation should ideally work towards helping you tolerate running.

What About Jumping And HIIT?

The same principle applies.

If repeated high-impact exercise consistently produces substantial leakage, simply doing more and hoping it disappears may not be the best strategy.

But permanently banning jumping may not be necessary either.

We can manipulate jump height, repetitions, rest, speed, landing task, exercise order and total session volume, then progressively increase demand as capacity improves.

Is Leakage During Exercise Dangerous?

Urinary leakage itself does not necessarily mean you are causing damage every time you exercise.

But it is a symptom worth addressing, particularly if it is affecting your confidence, participation or quality of life.

You should not need to organise your entire exercise routine around hiding leakage.

Should I Wear A Pad And Keep Training?

Pads can be useful for symptom management.

But if you are wearing one purely because you assume leakage cannot be changed, it may be worth seeking assessment.

Managing the consequence and rehabilitating the contributing factors are different things.

There is nothing wrong with using a pad while you exercise if you need one. It simply does not have to be the only strategy.

How Does A Women’s Health Physiotherapist Assess Leakage?

Assessment begins with a detailed history.

We may ask about when leakage occurs, how much you leak, pregnancy and birth history, menstrual or menopausal status, bladder habits, bowel function, pelvic heaviness

or pressure, pelvic pain, exercise and training history and your goals.

Depending on your presentation and consent, a pelvic floor assessment may also be discussed.

The purpose is to understand pelvic floor strength, endurance, coordination and relaxation where relevant.

We can then connect those findings to the activities that provoke symptoms.

Do I Need An Internal Pelvic Floor Examination?

An internal examination can provide useful information in some Women’s Health

Physiotherapy assessments, but it is not something that should occur without your informed consent.

Your Physiotherapist should explain what the assessment involves, why it may be useful and what alternatives are available.

You can decline or stop an internal assessment.

Your comfort and consent matter throughout the process.

What Does Pelvic Floor Rehabilitation Look Like?

There is no single programme.

Depending on your assessment, rehabilitation may include pelvic floor muscle training, relaxation strategies where appropriate, breathing and pressure-management strategies, trunk strengthening, lower-body strength training, impact preparation, running or jumping progression, exercise modification and education around bladder habits.

The programme should change as you improve.

If your goal is returning to running, rehabilitation should eventually look more like preparation for running.

Why Strength Training Still Matters

A woman experiencing leakage does not need to become afraid of loading her body.

Strength training is valuable for muscle, bone and physical function.

This becomes particularly important across adulthood and through menopause.

Where symptoms occur during lifting, we can assess the task and modify variables while building capacity.

The goal should be intelligent loading, not avoiding resistance forever.

Can Clinical Pilates Help?

Clinical Pilates can be useful within a broader pelvic health programme because it allows us to progressively train trunk, hip and whole-body strength while modifying load and position.

At Body Form, the Reformer, Trapeze Table, Wunda Chair, Spine Corrector and free weights can all be used depending on the client’s goals.

But Pilates equipment does not magically “fix” the pelvic floor.

Its value comes from how we use it.

For one woman, Clinical Pilates may provide an appropriate early return to exercise. For another, it may sit alongside heavier strength work and a return-to-running programme.

Is Reformer Pilates Safe With Pelvic Floor Symptoms?

Often, yes, with appropriate individualisation.

The important question is not whether an exercise is technically Pilates.

It is what pressure, resistance and physical demand the exercise creates for that person.

Symptoms can guide modification while capacity is developed.

A Women’s Health Physiotherapist can help determine what is appropriate if you are unsure.

What If I Feel Heaviness Or Bulging Instead Of Leakage?

Pelvic heaviness, dragging or a sensation of vaginal bulging can be associated with pelvic organ prolapse and should be discussed with an appropriately trained health professional.

Not all pelvic floor symptoms are stress urinary incontinence.

This is why symptom-specific assessment matters.

What If I Have Urgency Rather Than Leakage With Exercise?

Urinary urgency and urge-related leakage are different from classic stress urinary incontinence, although some people experience a mixture of symptoms.

If your main problem is a sudden intense urge to urinate, leakage on the way to the bathroom or unusually frequent urination, your assessment and management may differ.

Again, “just do Kegels” is not a sufficient answer for every bladder symptom.

When Should I Seek Medical Advice?

Seek appropriate medical review if you notice blood in your urine, recurrent urinary tract symptoms, unexplained pelvic pain, significant difficulty emptying your bladder or other new or concerning urinary symptoms.

Your Physiotherapist can also advise when medical assessment is appropriate.

You Do Not Have To Accept Exercise Leakage As Your New Normal

There is an important middle ground between pretending leakage is not happening and becoming afraid of exercise.

You can acknowledge the symptom, assess what is contributing, modify the current demand where needed, build the relevant capacity and then progressively return to the activities that matter.

For some women, that is running.

For others, CrossFit, netball, jumping with their children, lifting heavy weights or simply sneezing without worrying about leakage.

At Body Form Physiotherapy & Clinical Pilates, our Women’s Health Physiotherapy approach combines pelvic floor assessment with whole-body rehabilitation.

We do not look at the pelvic floor in isolation from the person attached to it.

Where appropriate, rehabilitation can incorporate Clinical Pilates, progressive strength work and a graded return to higher-impact activity.

If you are leaking when you run, jump, cough, sneeze or exercise, you do not need to wait until the symptom becomes severe before seeking help.

Book a Women’s Health Physiotherapy assessment with Body Form and let us help you understand what is happening and build a programme around the activities you actually want to return to.
