You press your fingers into your belly, just above your navel, and feel a soft gap. You've googled "mummy tummy" and "ab separation" at 2 a.Your lower back aches after standing too long. Maybe it's two fingers wide. Worth adding: maybe three. m. Your stomach domes when you sit up from the couch. and now you're here.
Here's the thing: diastasis recti is incredibly common. It's also wildly misunderstood. That's why most people either panic or ignore it completely. Neither helps.
Let's figure out what's actually going on with your core Most people skip this — try not to..
What Is Diastasis Recti
Diastasis recti abdominis — DRA for short — is a separation of the rectus abdominis muscles. So they're connected by a band of connective tissue called the linea alba. Those are the "six-pack" muscles running down the front of your abdomen. When that tissue stretches and thins, the two muscle bellies pull apart.
It's not a tear. It's not a hernia. Think about it: the muscles themselves are fine. The problem is the connective tissue between them has lost tension.
It happens for reasons you'd expect — and some you wouldn't
Pregnancy is the big one. In real terms, your uterus expands, your abdominal wall stretches, hormones like relaxin soften connective tissue. By the third trimester, nearly 100% of pregnant women have some degree of separation. Worth adding: that's normal. It's supposed to happen Not complicated — just consistent..
But it also shows up in:
- Men with significant weight gain or improper lifting mechanics
- People who do high-pressure core exercises without proper form (looking at you, crunches and sit-ups)
- Anyone with chronic coughing or straining from constipation
- Newborns — it's common in infants and usually resolves on its own
The separation can be above the navel, below it, or across the whole midline. Here's the thing — width matters. Depth matters more.
Why It Matters / Why People Care
A gap in your abs isn't just cosmetic. The linea alba is supposed to transfer force across your trunk. When it's lax, your core can't generate or manage pressure effectively Small thing, real impact..
What that looks like in daily life
You might notice:
- A visible bulge or "cone" down the midline when you sit up, do a plank, or lift something heavy
- Lower back pain that won't quit — your core isn't stabilizing your spine
- Pelvic floor issues: leaking when you sneeze, heaviness, pain with intimacy
- Poor posture — ribs flared, pelvis tilted forward, glutes switched off
- Feeling "weak in the middle" even if your limbs are strong
- Digestive sluggishness or bloating that gets worse as the day goes on

The doming is the classic sign. Which means you lie back, lift your head, and your stomach tents up like a Looney Tunes character. That's your intestines pushing through the gap because the front wall isn't holding.
But here's what most people miss: you can have a diastasis without obvious doming. And you can have doming without a clinically significant diastasis. The only way to know is to check.
How to Check Yourself
You don't need a referral. You need two minutes, a flat surface, and honest fingers Not complicated — just consistent..
The standard self-test
- Lie on your back, knees bent, feet flat on the floor. Relax your belly completely. Don't suck in. Don't brace.
- Place two or three fingers horizontally just above your belly button, pointing toward your toes.
- Gently lift your head and shoulders off the floor — just a crunch, not a full sit-up. Exhale as you lift.
- Feel for the edges of the rectus muscles on either side of your fingers. Can you feel them? How far apart are they?
- Repeat at the belly button, then two inches below.
What you're measuring:
- Width: How many fingers fit in the gap? One finger is borderline. Two or more is a positive finding.
- Depth: How far do your fingers sink in? A firm, springy end-feel is good. Mushy, no bottom? That's compromised connective tissue.
- Tension: Can you generate tension across the gap? Try a gentle pelvic floor lift + exhale. Does the gap narrow? Does it firm up?
A few things that throw people off
- Checking too high or too low. The gap changes along the midline. Check all three spots.
- Holding your breath. That spikes intra-abdominal pressure and widens the gap artificially. Exhale on the lift.
- Lifting too high. A full sit-up recruits hip flexors and changes the mechanics. Head and shoulders only.
- Only checking at rest. A functional diastasis might measure two fingers at rest but generate great tension. A non-functional one might measure one finger but feel like mush. Function > width.
When to see a pro
Self-testing is a solid starting point. But a pelvic health physio or trained professional can:
- Assess tissue quality more accurately
- Check for hernias (umbilical, epigastric, incisional)
- Evaluate your breathing pattern, rib cage mobility, pelvic floor coordination
- Give you a baseline and a progression plan
If you're postpartum, get checked at your 6-week visit — or book a pelvic PT session anyway. Also, if you're not postpartum and suspect a diastasis, same deal. Don't guess Less friction, more output..
Common Mistakes / What Most People Get Wrong
"I'll just do planks and crunches to close the gap"
Please don't. In real terms, you'll dome. You'll widen the gap. Traditional forward flexion (crunches, sit-ups, bicycles) and full planks often increase intra-abdominal pressure without the deep core coordination to manage it. You'll reinforce the pattern that got you here.
"If I lose weight, it'll go away"
Weight loss helps reduce visceral fat pushing outward. But the connective tissue laxity remains. In practice, plenty of lean people have diastasis. On the flip side, plenty of larger-bodied people don't. It's not a body fat issue.
"Surgery is the only fix"
Surgery (abdominoplasty with muscle plication) exists. You still need the rehab after. It's valid for some. But most people improve significantly with targeted rehab. Because of that, surgery doesn't retrain your motor control. Start with rehab.
"I have a small gap, so I'm fine"
Width isn't everything. A one-finger gap with zero tension generation is more problematic than a two-finger gap that firms up beautifully on exhale + pelvic floor engagement. Function wins.
"It's been years — too late now"
Connective tissue remodels slowly. But it does remodel. I've seen women 20 years postpartum make measurable changes in six months of consistent work. The body doesn't expire Which is the point..
What Actually Works
This isn't a six-week challenge. It's a practice. The goal: restore tension in the linea alba, retrain the deep core system, and manage pressure across all movements Simple as that..
1. Learn to breathe — really breathe
Most people breathe into their upper chest or belly only. Practically speaking, you need 360-degree expansion: ribs wide, back wide, belly gentle, pelvic floor descending on inhale. On exhale, the pelvic floor lifts, the transverse abdominis draws inward, the ribs narrow.
Try this: Lie on your side. In practice, inhale into your back ribs. Exhale through pursed lips like you're blowing through a straw. Feel your waist narrow. That's your transverse abdominis. That's the muscle that pulls the rectus bellies together.
2. Coordinate pelvic floor + breath + transverse abdominis
They're a team. If you only cue "draw belly to spine," you'll likely bear down on your pelvic floor. Even so, they fire together. Not good.
The connection breath:
- Inhale:
...expand your ribs 360 degrees, let your belly soften naturally, allow your pelvic floor to gently descend
- Exhale: purse your lips, draw your ribs down and back, feel your transversus abdominis engage to create gentle waist narrowing, let your pelvic floor naturally lift upward
Practice this sequence 5-10 times daily, even while sitting at your desk. The coordination is more important than duration initially.
3. Progress through pressure management layers
Layer 1: Static holds with proper breathing Start with dead bug variations, modified planks on knees, or bird dogs—all coordinated with the connection breath. Hold for 5-10 seconds, rest equal to hold time. Quality over quantity.
Layer 2: Dynamic movements Once static holds feel solid, progress to step-ups, modified bear crawls, or supported side planks. Maintain the breathing pattern throughout Small thing, real impact..
Layer 3: Functional integration Integrate core stability into daily movements: proper lifting mechanics, controlled transitions from sitting to standing, gait retraining if needed The details matter here. Took long enough..
4. Address underlying contributors
Diastasis rarely exists in isolation. Common co-conspirators include:
- Weak glutes leading to anterior pelvic tilt
- Thoracic spine restrictions limiting proper breathing mechanics
- Poor hip mobility affecting movement patterns
- Chronic cough or constipation creating repeated pressure spikes
Treat the whole system, not just the midline.
5. Monitor and adjust
Check your progress monthly by re-measuring at the umbilicus in a relaxed supine position. Improvement looks like:
- Increased tension when gently drawing medial boundaries inward
- Reduced gap width
- Better endurance in daily activities
- Decreased low back discomfort
Easier said than done, but still worth knowing Small thing, real impact..
Track these functional markers alongside measurements.
When to Seek Additional Support
Consider working with a certified pelvic health physical therapist for hands-on assessment and manual therapy if you experience:
- Pain or discomfort during exercises
- Urinary leakage with coughing, sneezing, or lifting
- Constipation or pelvic floor dysfunction
- Severe separation (>4 finger widths)
- Previous abdominal surgery
Self-referral is often possible through telehealth platforms specializing in women's health Most people skip this — try not to. Still holds up..
The Long Game
Diastasis recti rehabilitation demands patience because connective tissue adapts slowly. Even so, you're essentially teaching your body new movement habits while restructuring tissue architecture. This takes months, not weeks.
Consistency beats intensity. Twenty minutes daily of focused practice yields better results than two hours on Sunday followed by neglect. Your nervous system needs repetition to form new motor patterns Small thing, real impact. Practical, not theoretical..
Celebrate non-scale victories: improved posture, reduced back pain, better breathing efficiency, increased confidence in movement. These often precede visible anatomical changes.
Remember that perfection isn't the goal—functional improvement is. Some asymmetry may persist, and that's okay. The aim is a stronger, more resilient core that serves you through life's movements, not a photo-perfect six-pack.
Your body brought you here for a reason. Trust the process, honor the timeline, and invest in long-term mobility and stability. The work you do today becomes the foundation for tomorrow's physical confidence Most people skip this — try not to. And it works..
