How to Check for Diastasis Recti at Home (And What Your Results Mean)

How Do I Check Myself for Diastasis Recti at Home?

 Lie on your back with knees bent. Place your fingertips horizontally across your midline just above your belly button. Slowly lift your head and shoulders as if beginning a sit-up, and feel for a gap or softness in the tissue beneath your fingers. A gap of two fingers or more with soft tissue is worth investigating further with a women's health physio.

You Can't Train What You Haven't Checked -- and Most Postnatal Women Skip This Step Entirely

Diastasis recti is one of the most commonly discussed postnatal topics, and also one of the most misunderstood. The fear around it can send women in completely the wrong direction: avoiding all core work, obsessing over 'closing the gap', or -- on the other end -- jumping straight back into crunches and wondering why things feel worse.

The self-check below gives you a clear, practical starting point -- not to diagnose, but to understand what your core is doing right now so you can train in a way that helps it.

What Is Diastasis Recti?

Diastasis recti is the separation of the abdominal muscles -- specifically the two vertical strips of muscle that run down the left and right sides of your stomach, connected in the middle by a strip of connective tissue called the linea alba.

During pregnancy, as your baby grows, the linea alba stretches to create space. The result is that the two sides of your abdominal muscles move further apart. This separation is diastasis recti.

Here's the important part: it's not a hole in your muscles. They're still connected. The connective tissue has simply stretched, and that changes how well your core can generate tension and manage load.

 Almost all women develop some degree of diastasis during pregnancy. It's a normal adaptation, not a sign that something has gone wrong. The question is whether your linea alba has regained its tension and ability to support your core after birth.

Common Myths About Diastasis, Cleared Up

Myth 1: Diastasis Is a Hole in Your Stomach

No. The connective tissue is still there -- it's just stretched. The muscles haven't separated; they're still attached to the linea alba on both sides.

Myth 2: You Have to Close the Gap

The gap is not the goal. What matters is whether your linea alba has regained tension and whether your core can support movement and manage pressure properly. A small persistent gap with good tension is far better than a closed gap with no strength behind it.

Myth 3: You Can't Get a Flat Tummy with Diastasis

You absolutely can. Restoring core function and midline tension typically produces visible changes -- in the right order. Core function first, aesthetics follow.

Functional vs Non-Functional Diastasis: What the Distinction Means

Functional Diastasis

There is still some separation between the abdominal muscles, but the connective tissue in the middle feels firm and supportive. The core can generate tension, manage pressure, and support movement effectively. The body is functioning well even if the gap hasn't fully closed.

Non-Functional Diastasis

The connective tissue along the midline feels soft or unsupported and can't generate proper tension. The core struggles to provide enough support during movement, which can show up as back pain, pelvic floor symptoms, or difficulty with loading.

The goal is not to eliminate the gap. The goal is functional diastasis.

What Are the Signs That Your Diastasis Might Be Non-Functional?

• A domed or coning shape appearing at the midline when you perform abdominal exercises or sit up.

• Difficulty lifting, carrying, or loading without discomfort or back pain.

• A soft or 'squishy' feeling along the midline rather than firm resistance.

• Persistent pelvic floor symptoms that haven't improved with correct training.

Any of these alone is not a definitive answer, but they're worth paying attention to.

What Can Your Self-Check Results Tell You?

Six Weeks or More Postpartum and Linea Alba Feels Soft

If your midline hasn't regained tension by around six weeks postpartum, you may need specific support to restore it. This means focusing on coordinating your breath, pelvic floor, and deep core before adding load. Our Feel and Heal program is built for this starting point.

Three Fingers Wide or More

It's worth seeing a women's health physio or qualified professional for a proper assessment. Check our Little Black Book of Women's Health Professionals -- no sponsorships, just practitioners we trust.

Cannot Feel or Find the Midline

Very common. Don't stress. A professional check will give you the clarity you need to start moving forward confidently.

No Diastasis

Great news. Your midline has good tension and support. Continue training with attention to pressure management and core control. Our Core Connections program would be a strong fit.

FAQs: Diastasis Recti Self-Check

How Do I Check Myself for Diastasis Recti at Home?

Lie on your back with knees bent, feet flat. Place your fingertips horizontally across your midline just above your belly button. Slowly lift your head and shoulders as if beginning a sit-up, and feel for a gap or softness in the tissue beneath your fingers. A gap of two fingers or more with soft tissue is worth investigating further.

Does Diastasis Recti Heal on Its Own?

For many women, especially in the early weeks postpartum, the gap reduces naturally as the body heals. Whether the tissue regains full functional tension without intervention varies between individuals. Targeted training can significantly improve outcomes, particularly for non-functional diastasis.

What Exercises Should I Avoid with Diastasis Recti?

Exercises that create visible doming or coning at the midline are a sign that the load is too much for your core right now. This often includes heavy sit-ups, traditional planks for some women, and high-load lifts performed without proper intra-abdominal pressure management.

Can Diastasis Recti Come Back After Healing?

Yes -- repeated significant increase in abdominal pressure from another pregnancy, significant weight gain, or high-impact training without adequate core preparation can stretch the linea alba again. This is why rebuilding pressure management skills, not just closing the gap, is such a crucial part of long-term recovery.
