You Don't Have to Close the Gap: The Diastasis Myth Misleading Thousands of Women

Does Your Diastasis Recti Gap Have to Close to Heal?

No. The gap is not the measure of recovery -- core function is. A small persistent gap with good midline tension is far better than a closed gap with no strength behind it. What matters is whether your linea alba has regained its ability to generate tension and support movement. Many women with a persistent gap have excellent core function and zero symptoms.

Almost every conversation about diastasis recti centers on one question: how do I close the gap? And it's the wrong question.

The gap is not the problem. A soft, unsupportive midline is the problem. And those are not the same thing.

What Diastasis Recti Is

Diastasis recti is the stretching of the linea alba -- the connective tissue connecting your two vertical abdominal muscles. During pregnancy, this tissue stretches to make space for your baby. Almost all women experience some degree of it.

After birth, the question isn't whether a gap exists. The question is whether your linea alba has regained the tension it needs to support movement, manage pressure, and transfer load through your core.

A Gap with Good Tension Is Not a Problem

This is called functional diastasis. There is still some separation, but the connective tissue is firm and supportive. The core can generate tension and support you during movement. A narrow gap with soft, unsupportive tissue is more of a problem than a wide gap with good tension. Finger-width measurements alone tell an incomplete story.

Shay says: I once tested a group of fitness coaches for diastasis during a workshop. Three out of five had it. Only one had ever been pregnant. They had strong abs and trained hard. Diastasis is about tissue quality, not just gap width.

What You Should Be Working Toward

A core that can generate tension through the midline, manage pressure correctly, and support you during movement. That means training the coordination between your breath, pelvic floor, and deep core before adding load -- and measuring progress by how your body performs, not whether the gap has closed.
