Diastasis Recti After Baby: Why That Belly Gap Isn't a Crunch Problem (A Sheepshead Bay PT Explains)

If you've been poking at that gap down the middle of your belly, or you've noticed a little ridge or 'tenting' pop up when you sit up in bed, I want to start with this: you are so not alone, and you didn't do anything wrong. This comes up in my Sheepshead Bay office constantly. Diastasis recti is one of the most common things new (and not-so-new) parents ask me about, and one of the most misunderstood.

First, what diastasis recti actually is

Diastasis recti (DR for short) is a widening of the connective tissue called the linea alba that runs down the center of your abdomen, between the two halves of your 'six-pack' muscles. During pregnancy, your growing belly stretches that tissue to make room for baby. That's not damage. That's your body doing exactly what it's supposed to do. For a lot of people it narrows back on its own in the months after birth; for others it lingers, and that's where some focused work helps.

Here's the part I really want to land: a small gap by itself isn't the problem. What matters far more is how well that tissue and your deep core generate tension and manage pressure. Two people can have the same 'gap width' and feel completely different in their bodies. That's why the old measuring-tape obsession misses the point.

How to spot it at home (gently)

You don't need fancy tools to notice the signs. Common things people describe to me:

• A visible bulge, doming, or 'coning' down the midline when you sit up, cough, or lift something.
• A soft, 'mushy' or disconnected feeling through your middle, like your core can't quite brace.
• Low-back achiness, a feeling of pressure, or leaking when you laugh or sneeze (the pelvic floor and abdominals work as one team).
• A belly that still looks pregnant months out, even though everything else has changed.

Please hear me: noticing these is information, not a verdict. I'm describing general patterns here, not diagnosing you, and I can't tell you what's going on in your body from a blog post. An in-person look is the only way to really know.

Why crunches and planks can backfire

This is the myth I most want to retire. So many of my patients arrive having been told to 'just do crunches' or 'hold a plank' to close the gap. But if your deep core and pelvic floor aren't coordinating yet, those exercises can actually push pressure outward against that vulnerable midline, which is the very thing we're trying to avoid. If your belly cones up into a ridge during an exercise, that's your body telling you it's too much, too soon.

It's the same idea I tell people about Kegels: more squeezing isn't automatically the answer. Real core rehab is about coordination and pressure management, not heroic effort. Small, consistent, well-timed work beats grinding through movements your core can't yet support.

What gentle core reconnection can look like

A quick reminder before I share these: this is general education, not a personalized program. The right starting point really does depend on your body. But these are the calm, low-effort building blocks I often introduce early:

• Diaphragmatic (belly) breathing: lying down, knees bent, breathe in softly through the nose and let the belly and ribs expand, then exhale slowly. Your diaphragm and pelvic floor move together, so this is the foundation.
• Connection breath: on the exhale, gently feel your deep core and pelvic floor respond together in a soft lift, then fully relax on the inhale. Low-key and unglamorous, which is exactly the point.
• Posture and pressure awareness: stack your ribs over your pelvis, avoid gripping your belly or holding your breath, and exhale on effort, like when you lift your baby or a stroller up the stairs.

6 weeks or 6 years out, it's never too late

One of my favorite things to tell people in Gravesend, Marine Park, and Brighton Beach: there's no expiration date on this work. Whether you're freshly cleared at six weeks or your 'baby' is in middle school, your core can learn to coordinate and generate tension again. I see it all the time, and it's genuinely empowering to watch someone go from 'I avoid lifting' to confidently picking up their kid (or their barbell) again.

Let's take a real look together

At OrthoPelvic Doc, every visit is one-on-one with me. Your initial evaluation includes a diastasis recti screening, a breathing and posture assessment, and a clear, individualized plan built around your body and your goals, not a generic checklist. No two cores are the same, so no two plans should be either.
