Sports That Strengthen (and Punish) the Pelvic Floor

Did you know that some high-impact sports can put as much strain on your pelvic floor as the effort of childbirth? It sounds counterintuitive: exercise is supposed to strengthen you, not weaken you. But the pelvic floor doesn’t work like other muscles: not every impact trains it, and some of the sports most recommended for “getting fit” are precisely the ones that put the most pressure on these muscles. Here’s which sports really strengthen it, which ones to keep an eye on, and how to keep training without taking risks.

What the pelvic floor is and why exercise affects it so much

The pelvic floor is the group of muscles and ligaments that supports the bladder, uterus and rectum, like a hammock that stops these organs from dropping. Together with the abdominal and lower back muscles it forms what’s known as the core, the body’s center of stability. You can read the full explanation in our guide to what the pelvic floor is and how to strengthen it.

The problem is intra-abdominal pressure: every time you jump, run or lift weights while holding your breath, that pressure pushes down on the pelvic floor. If the muscles are trained and coordinated with your breathing, they absorb it well. If not, each repetition is a small cumulative blow that, over the years (and especially after childbirth), can lead to urinary incontinence or pelvic organ prolapse.

Sports that strengthen the pelvic floor

Low- or medium-impact exercise, which doesn’t create sudden spikes in intra-abdominal pressure, is what really trains these muscles:

• Pilates. Works the core consciously, coordinating breathing and contraction, with no impact.
• Hypopressive exercises. A specific technique that reduces intra-abdominal pressure instead of increasing it; it’s the training most recommended by pelvic floor physiotherapists.
• Yoga. Combines stretching, breath control and postures that activate the core without sudden overload. If you practice during your period, see doing yoga with a menstrual cup.
• Gentle swimming and walking. Low-impact cardio, with no jumps or repeated vertical loads.
• Specific Kegel exercises, which isolate the pelvic muscles directly. We explain how to do them right in our guide to Kegel exercises.

Disciplines to watch if your pelvic floor is weak

This isn’t about giving up exercise —a sedentary lifestyle doesn’t help the pelvic floor either— but about knowing which disciplines call for more care, especially if you already have symptoms or have recently given birth:

• Running and high-intensity CrossFit, especially at high volume and with poor breathing technique.
• Sports with repeated jumping: trampoline, boxing with footwork, basketball, volleyball.
• Weightlifting with the Valsalva maneuver (holding your breath and bearing down) without proper technique.
• Too many classic sit-ups (crunches), which increase intra-abdominal pressure without activating the pelvic floor in a coordinated way.

If you recognize symptoms such as leaking when you cough or jump, a feeling of heaviness in the vagina or discomfort after training, check our guide on how to tell if your pelvic floor is weak and consider seeing a physiotherapist who specializes in the pelvic floor before continuing with heavy loads.

How to keep training without putting your pelvic floor at risk

You don’t have to choose between “exercising” and “looking after your pelvic floor”. With a few adjustments, most sports can be practiced more safely:

1. Learn to activate your pelvic floor before the effort, contracting it gently as you breathe out at the moment of greatest load (when lifting, when jumping).
2. Add 2-3 weekly sessions of hypopressives or Kegels as a complement to your main sport, not a substitute.
3. Reduce your impact volume during more vulnerable periods: postpartum, perimenopause, or if you already have mild symptoms.
4. Don’t hold your breath during strength efforts; breathe out at the moment of greatest demand instead of locking the air in.

The scientific evidence supports specific pelvic floor training, and the review in The Lancet Public Health (2019) on reusable menstrual products also reinforces that you can keep using a menstrual cup normally while exercising, with no added risk if your pelvic floor is healthy. In fact, a menstrual cup for athletes is often more comfortable than a tampon during high-impact exercise, precisely because it doesn’t dry you out or shift in the same way.

A basic 5-minute hypopressive routine

You don’t need to sign up for a specialist class to get started. This simple sequence, standing or lying down, is a good starting point:

1. Neutral posture: feet in line with your hips, spine lengthened, shoulders relaxed.
2. Breathe in deeply, taking the air into your abdomen without lifting your shoulders.
3. Breathe all the air out slowly, emptying your lungs completely.
4. With your lungs empty, “open your ribs” as if you were breathing in again, but without letting air in (expiratory apnea). You’ll notice your abdomen draws in on its own.
5. Hold for 8-10 seconds and release slowly, going back to normal breathing.
6. Repeat 5-8 times, resting for one normal breath between repetitions.

Coordinating the maneuver can be tricky at first; that’s normal. If you have a history of high blood pressure or glaucoma, or you’re pregnant, check with your doctor or physiotherapist first, as expiratory apnea isn’t advisable in every case.

After training, look after your intimate hygiene too: an intimate gel with a probiotic complex, pH 3.5 after a sweaty workout helps keep the area in balance, and if you train away from home, keeping your cup or accessories in a SileuCase inside your gym bag stops them getting dirty or knocked about among the rest of your kit.

Pelvic floor, sport and postpartum: a special case

If you’ve recently given birth (vaginally or by C-section), your pelvic floor needs recovery time before you go back to high-impact sports, however fit you were before pregnancy. Our guide to the pelvic floor in pregnancy and postpartum details which exercises are safe at each stage. And if you also notice urine leaks when exercising, it isn’t “normal and inevitable”: in mild urinary incontinence we explain why it happens and how to improve it, often with the same specific training we’ve described here. If you’d prefer a more gradual approach than the Kegel stones, Kegel balls vs. a Kegel trainer is another comparison that can help you decide where to start.

A final note on expectations: strengthening the pelvic floor isn’t a one-week process, just as building muscle anywhere else in the body isn’t. Physiotherapy studies usually talk about 8 to 12 weeks of consistent training to notice a clear improvement in the strength and control of these muscles, whether with Kegels, hypopressives or a combination of both. Consistency matters more than intensity: 10 well-done minutes a day beat a long, occasional session once a week.
