The Diastasis Recti Self-Check

A quick at-home screen for the abdominal separation that most postpartum core programs skip. Designed by a NASM-certified prenatal/postpartum trainer.

The 60-second screen

Five steps. Lying down. Two fingers. Done in a minute.

Match your breath to the pulsing circle as you do each step — the screen is more accurate when your core isn't bracing.

    01

    Lie down, knees bent

    Lie on your back with knees bent and feet flat on the floor. Pillow under your head if you want. Relax for 5 breaths.

    02

    Place two fingers above your belly button

    Two fingers, horizontal, palm facing your chin. Press gently. You're sitting on top of the linea alba — the connective tissue between your two ab columns.

    03

    Lift your head and shoulders slightly

    Like the very first inch of a crunch. You should feel the two muscle columns rise on either side of your fingers.

    04

    Note the width AND depth of the gap

    How many fingers fit between the two columns? How deep do your fingers sink before you hit firm tension? Both numbers matter — width AND depth.

    05

    Repeat at two more points

    Move 2 inches above the belly button (toward your sternum) and 2 inches below (toward your pubic bone). The gap can vary at each point.

What your result means

Width and depth both matter. Use the chart below to get a rough sense of where you are.

What you foundWhat it means
0–1 finger-widths, shallowNormal. No diastasis. Train freely with awareness of breath and pressure under load.
1–2 finger-widths, shallow tensionBorderline. Most pregnancies leave this. Responds quickly to focused deep-core and pelvic floor work over 4-8 weeks.
2–3 finger-widths, moderate depthMild-to-moderate diastasis. Avoid sit-ups, crunches, and heavy front-loaded movements. Focus on diaphragmatic breathing, transverse abdominis activation, and glute work for 8-12 weeks before progressing.
>3 finger-widths, or deep gapModerate-to-severe. Worth seeing a pelvic floor physical therapist for an in-person assessment. Training can still help — the right program just matters more.
Visible bulge or dome when you liftStrong sign of weak connective tissue tension or potential hernia. See your OB or a pelvic floor PT before continued exercise.

When to skip the trainer and see a pelvic floor PT

A great trainer (NASM-CPT, pre/postnatal certified) can manage most diastasis cases. But not all. Here's when to escalate.
