Your Core Is More Than Your Abs — And Your Pelvic Floor Is Part of It
When most people think about their core, they think about their abs.
Crunches. Planks. Maybe that burning sensation in the front of your stomach that tells you something is working.
But your core is much more than the muscles you can see.
It is a coordinated system that helps you create stability, manage pressure, transfer force, and move efficiently.
And your pelvic floor is part of it.
That matters whether you're recovering postpartum, dealing with leaking or pelvic pressure, trying to get stronger, or simply wanting your body to perform better.
Your Core Is a System
One way to picture your core is as a canister.
At the top is your diaphragm, your primary breathing muscle.
Around the front and sides are your abdominal muscles, including deeper layers like the transverse abdominis as well as the more superficial muscles you typically think of as your “abs.”
Along the back are the muscles that support and control your spine.
And at the bottom is your pelvic floor.
These structures don't function independently. They coordinate as you breathe, brace, lift, run, jump, carry your kids, get off the floor, and move through everyday life.
When you inhale, your diaphragm descends and your pelvic floor typically lengthens with it.
When you exhale, both move back upward.
Add movement or load, and the strategy becomes more complex.
Your abdominal wall, diaphragm, spinal muscles and pelvic floor all contribute to managing pressure and creating the stability you need for the task in front of you.
That's your core doing its job.
Why Your Pelvic Floor Belongs in the Core Conversation
This is where pelvic health and orthopedic care start overlapping.
If you're leaking during a lift, experiencing pelvic pressure while running, or having difficulty returning to exercise postpartum, it can be tempting to focus entirely on the pelvic floor.
But I'm also interested in what the rest of your body is doing.
How are you breathing?
How are you bracing?
How does your trunk respond to load?
What are your hips doing?
Can you create tension when you need it—and let that tension go afterward?
What changes when you increase the weight, speed, impact, or fatigue?
Sometimes the pelvic floor itself needs specific treatment.
Sometimes changing something elsewhere in the system changes the symptom.
Often, we need to address both.
That's why pelvic health doesn't make sense to me in isolation from the rest of the body.
Strong Abs Don't Automatically Mean a Strong Core
You can have visible abs and still struggle with leaking.
You can hold a plank for two minutes and still have pelvic pressure when you run.
You can be incredibly strong and still have difficulty coordinating your trunk and pelvic floor for a particular task.
That's because strength and coordination aren't the same thing.
Your body doesn't just need muscles that can produce force.
It needs muscles that can coordinate force, respond to changing demands, tolerate load, and relax when the task is over.
That's especially important for the pelvic floor.
A pelvic floor that can contract but can't relax isn't functioning optimally.
A pelvic floor that's strong during an isolated contraction may still struggle with the repeated impact of running or the pressure demands of a heavy squat.
And someone can have excellent abdominal strength while still needing a different strategy for a particular movement.
The goal isn't simply stronger abs. It's a system that can meet the demands you place on it.
And No, This Doesn't Mean Crunches Are Bad
This is one place I’d intentionally push back on common pelvic-health messaging.
Crunches aren't inherently bad.
Planks aren't inherently bad.
Heavy lifting isn't inherently bad.
And Kegels aren't inherently bad either.
They're all tools.
A Kegel may be appropriate when pelvic-floor strengthening is actually needed.
A plank may be a perfectly good way to challenge the trunk.
A crunch can train your abdominal muscles.
A deadlift can train your entire system under significant load.
The question isn't whether an exercise is universally “good” or “bad.”
The question is whether it helps prepare your body for what you want it to do.
What Does Core Training Actually Look Like?
It depends on the person.
For someone early postpartum, it might start with reconnecting breathing, abdominal function, and pelvic-floor coordination.
For someone leaking during CrossFit, it might involve experimenting with breathing and bracing strategies while also assessing strength, mobility, technique, fatigue, and the pelvic floor itself.
For a runner, it may mean progressively exposing the system to impact while building the strength and capacity needed to tolerate thousands of steps.
And for someone without symptoms who simply wants to get stronger?
Core training might look a whole lot like lifting heavy things.
Squats. Deadlifts. Carries. Presses. Pulls.
Your core wasn't designed only to perform isolated exercises on a mat.
It helps you move, transfer force, and respond to the demands of real life and sport.
So eventually, that's where training should take you.
The Bottom Line
Your core is more than your abs.
And your pelvic floor isn't a separate system that needs to be protected from everything the rest of your body wants to do.
They work together.
That's why treating pelvic-floor symptoms without considering strength, movement, breathing, load, and the demands of your actual life can miss important pieces of the picture.
You don't just need a stronger core.
You need a core that works for what you want to do.

If pelvic floor symptoms, pain, or movement limitations are keeping you from doing the things you love, you don’t have to keep guessing. FitPelvis PT combines pelvic health, orthopedic care, and performance to look at the whole picture—not just one symptom.
