CrossFit class, second round of jump rope. Twenty jumps, good, forty, good, and at forty-two something happens that wasn't in your training plan. Just a moment, almost imperceptible, but it's there.
If you know exactly what you're reading about, welcome (and welcome to men too, because this isn't just about women). Urine leakage at the gym affects between 30% and 80% of those who train at high intensity, and in CrossFit specifically it has been documented in almost 1 out of 3 women, according to this analysis by OWA Academy on CrossFit and incontinence. Almost no one talks about it out loud, though. You put on a pad, you keep going, and you see what happens.
This post is about how to prevent those urine leaks at the gym, or at least manage them while you work on the root problem. Without stopping your training, and without resigning yourself to wearing granny pads at 25 years old.
First of all: no, you're not the only one
62.8% of Physical Education students, with an average age of 21, already presented stress urinary incontinence related to sports, according to data collected in EFDeportes, the sports science journal. An average of twenty-one years old. No postpartum, no menopause, no usual clichés.
And what is most surprising about more recent studies: 73.5% of women who experience urine leakage during exercise urinate before training "just in case" as a compensatory strategy, according to a 2022 study on urinary incontinence in young female athletes. Basically, training the bladder to ask for less and less occupancy, which is exactly the opposite of what is convenient.
When asked "are mild urine leaks during exercise normal?", the answer is yes, and it has a much better solution than is usually told.
Why you leak urine when you exercise
The pelvic floor works like a muscular hammock that supports the bladder, uterus, and rectum. When you jump, run, or lift weights, the pressure inside the abdomen suddenly increases, and if that hammock doesn't have enough tone or coordination to withstand the impact, the result is a leak.
It has nothing to do with having given birth (although childbirth can weaken it more). Nor with age, at least not in the way it is usually believed. Young athletes, without children, in very good physical condition: it also happens to them, and "crossfit young woman urinary incontinence without children" is a search many people make when they discover that the cliché doesn't fit their case.
The good news is that it is not irreversible. The pelvic floor is muscle, and muscle can be trained.
The exercises that generate the most pressure on the pelvic floor
Not all exercises create the same problem. There are two different mechanisms that trigger leaks.
On one hand, there are repeated impact exercises: burpees, jump rope, box jumps, high-intensity HIIT, Zumba, running, paddle tennis, and tennis. The pelvic floor receives blow after blow without time to recover between repetitions. On the other hand, there are hyperpressure exercises: deadlifts, weighted squats, BodyPump, any movement with heavy loads, where it's not the impact that fails but the intra-abdominal pressure generated by pushing.
And there's a third classic that makes things worse even if it seems harmless: traditional abdominal crunches, which go straight down onto the pelvic floor. That doesn't rehabilitate anything.
What if you're a man? They suffer from it too
Stress urinary incontinence in men exists, it is documented especially in runners and weightlifters, and it is much more silenced than in women. Same cause: sustained abdominal pressure on a pelvic floor that is not prepared to absorb it. Everything that follows applies exactly the same to men and women.
How to prevent urine leaks at the gym
There are solutions that really work, and not all of them involve months of waiting on a physical therapy list. Here's what you can start applying in your next workout.
1. Empty your bladder before training, but only once
Urinating 15-20 minutes before starting reduces initial pressure. The common mistake is to go to the bathroom every five minutes "just in case": this ends up training the bladder to demand with very little occupancy, which in the long run aggravates the problem. Once, before, and then only when there is a real need.
2. Learn the Knack maneuver
The Knack maneuver consists of contracting the pelvic floor just before the moment of impact or effort: before jumping, before pushing, before lifting. It is not the same as doing Kegel at home generically (that is rehabilitative), but functional, protective Kegel, activated at the exact moment it is needed.
In practice: half a second before each jump or repetition, you clench. Over time, it becomes automatic and no longer requires conscious attention.
3. Replace classic crunches with hypopressives
Traditional crunches increase intra-abdominal pressure downwards, directly onto the pelvic floor. Hypopressives (Low Pressure Fitness method, developed by Tamara Rial and Pity Pinsach) work the core without generating that downward pressure and have been specifically used in pelvic floor rehabilitation. It's not about abandoning crunches: it's about replacing one with the other until the pelvic floor is stronger.
4. Review technique before lowering intensity
For running: cadence of about 180 steps per minute, without landing on the heel, avoid hard surfaces when possible. In deadlifts and squats, load distribution and correct bracing make a big difference. And breathing: always exhale on the push, never hold your breath (holding your breath is what generates the most pressure on the pelvic floor, and at the same time what is done most often without realizing it). A trainer with pelvic floor knowledge can make all of this click sooner than expected.
5. Stay hydrated without sabotaging yourself
The most typical mistake: reducing water intake to "not pee" as much. Counterproductive: more concentrated urine irritates the bladder more and increases urgency, it doesn't reduce it. Caffeine before training adds to it: it's both a diuretic and an irritant, a double whammy. Proper hydration reduces symptoms, contrary to what it seems.
6. Go to a pelvic floor physical therapist, even if you are young and in shape
Pelvic floor physical therapy has a very high success rate without surgery or medication, and it's not just for postpartum or older people: it works for any athlete with urine leakage during exercise. The difference from doing Kegels at home is that the physical therapist works with biofeedback and tells you exactly if you are contracting the correct muscle or compensating with others (which is what happens in most cases). In Spain, search for "fisioterapeuta uroginecológico" plus your city.
7. Protect yourself while you solve the problem
The underlying solution is the pelvic floor. But while you're working on it (and that takes weeks, sometimes months), what do you wear to the gym tomorrow?
Conventional pads are not designed for movement: they shift, cause chafing, and do not absorb urine well (they are designed for menstrual flow, which is denser). Technical absorbent underwear is different: sporty design, discreet, reusable, and made to absorb exactly this type of mild leaks during physical activity.
For women, the PeeShorty Femme is an absorbent, lightweight, and washable short-style brief, designed for sports. For men, the PlanPee Reusable Underwear does the same in a boxer version: it absorbs mild leaks without extra bulk and is reusable.

Has the problem been ongoing for a while? Here's what you need to know
If you have been experiencing urine leakage during exercise for more than six months and changes in habits have not made a difference, it's time to see a specialist: a urogynecological physical therapist plus a gynecologist or urologist, depending on the case. Options range from guided rehabilitation to electrostimulation or biofeedback, all with a high success rate and without the need for surgery.
This post is for guidance. If you have frequent, intense leaks or leaks that affect your quality of life, a professional will be able to tell you much more than any article...
The body you train deserves the same attention as the muscles you see in the mirror.
Frequently asked questions about urine leakage at the gym
Is it normal to leak urine at the gym if I am young and haven't had children?
Yes, and it's more common than it seems. Stress urinary incontinence in young athletes without children is documented: the pelvic floor may have insufficient tone or poor coordination regardless of age or obstetric history. The type of sport you practice has more weight than is usually believed.
Can I continue doing CrossFit or HIIT if I have urine leaks?
Yes, with adaptations. Applying the Knack maneuver, reviewing the technique of impact exercises, and replacing crunches with hypopressives allows you to continue training while working on the problem. For sessions in the meantime, technical absorbent underwear, such as the PeeShorty Femme or the PlanPee Reusable Underwear, covers mild leaks without interfering with training. Reducing intensity is only necessary in severe cases, and always under professional guidance.
Does caffeine worsen urinary incontinence when I exercise?
Yes, twofold: caffeine is a diuretic (increases urine production) and an irritant to the bladder (lowers the threshold for urgency). Drinking coffee just before training exacerbates both pathways. It's not necessary to eliminate it, but saving it for after training can make a difference.
What is the best underwear for exercising with mild urine leaks?
Technical absorbent underwear designed for sports, not conventional pads. Pads shift with movement and do not absorb urine well. The PeeShorty Femme (women) and the PlanPee Reusable Underwear (men) are specifically designed for mild leaks during physical activity: reusable, washable, and without added bulk.
