Months on, your lower tummy still pokes out, so a two-minute self-check tells you which gentle fix actually works for you.
If your lower tummy still pokes out months after birth, you are not imagining it, and you are not alone. That soft, rounded shape across the middle has a nickname most mums quietly hate: the mum pooch. But here is the part nobody tells you in the early weeks. That pooch is not always what you think it is. Sometimes it is leftover belly fat. Sometimes it is diastasis recti, a gap in the tummy muscles that no amount of crunches will fix. And very often it is a mix of both. Knowing which one you are dealing with changes everything about what you should do next.
What actually causes the mum pooch?
During pregnancy your growing baby stretches the abdominal wall in two directions. The skin and fat layer expands outward, and the two halves of your six-pack muscle (the rectus abdominis) are pushed apart by the connective tissue down the middle, called the linea alba. After birth, both of these usually start to recover on their own. But recovery is rarely complete by the time you feel ready to look in the mirror, and the two issues behave very differently from each other.
So before you blame yourself, or your snack drawer, it is worth understanding that a stubborn pooch is an extremely common and very physical part of postpartum recovery. The good news is that the right approach can genuinely help. The not-so-good news is that the wrong approach, like aggressive crunches on top of an unhealed gap, can actually make a diastasis worse.
Belly fat vs diastasis recti: how do they compare?
Here is the clearest side-by-side. Use it as a starting point, not a diagnosis.
| Feature | Belly fat | Diastasis recti |
|---|---|---|
| How it feels | Soft and squishy, you can pinch a layer | A gap or dip down the midline, often firmer edges either side |
| When you lift your head | Stays roughly the same, no ridge | A ridge or dome pops up along the centre |
| Spread | Fairly even across the whole tummy and often elsewhere on the body | Concentrated along the centre line, especially below the belly button |
| Linked symptoms | None specific | Lower back ache, weak core, sometimes leaking or a feeling of pressure |
| What helps | Overall fat loss through diet, movement and time | Targeted deep-core work to rebuild tension, never just crunches |
Notice the row that matters most: when you lift your head. Fat does not form a ridge. A separated core does. That single observation is what the self-check below is built around.
How do I do the self-check at home?
This takes two minutes and you only need the floor and your own fingers.
- Lie on your back. Bend your knees, feet flat, and rest your head down to start.
- Find the midline. Place two or three fingers flat just above your belly button, pointing down towards your toes.
- Lift gently. Slowly raise your head and shoulders a few centimetres, like the very start of a tiny crunch.
- Feel for the gap. As your muscles engage, press softly. If your fingers sink into a soft channel with a firm wall on each side, that is the gap. Check above the belly button and below it too.
- Note the width and depth. Roughly how many finger-widths across, and does it feel shallow or does your hand sink deep with no resistance underneath?
A gap of one to two finger-widths that has a springy floor of tension is common and usually responds well to gentle rebuilding. A wider gap, or one that feels deep and soft with no bounce, is your cue to see a women's health physio rather than pushing on alone. If you feel a bulge that gets bigger when you cough or strain, get that checked by your doctor, as it could be a hernia.
Not sure if it is a gap or just fat?
The Diastasis Recti Fix walks you through the same self-check on video, then gives you a safe, progressive plan to rebuild your deep core at home, in nap-length sessions.

Being honest about this saves a lot of frustration. Here is the realistic picture.
What core work can do
- Rebuild tension in the linea alba so the gap narrows
- Make your midline flatter and your core stronger
- Ease lower back ache linked to a weak core
- Improve posture so your tummy looks and feels held
What no exercise can do
- Spot-reduce fat from one area on demand
- Remove loose skin left over after stretching
- Guarantee a flat result, every body recovers differently
- Replace medical care for a wide gap, hernia or ongoing pain
If your self-check points mostly to fat, gentle overall movement plus patient, sustainable eating habits do more than any tummy gadget. If it points to a gap, targeted deep-core breathing and progressive exercises come first, before any hard ab work. And if it is both, which is the most common case, you start with the core foundation and let the rest follow.
Where does a full reset fit in?
Many mums find the pooch is tangled up with low energy, weak glutes and a tired pelvic floor, all from the same season of growing and birthing a baby. If that sounds like you, working on the core in isolation can feel like only half the picture. The Complete Postpartum Body Reset bundles the core programme together with the other pieces so you rebuild the whole system, not just one part of it. Start where your self-check points you, and add the rest when you are ready.
The bottom line
The mum pooch is rarely just one thing. Do the two-minute self-check first. If you feel a ridge or a gap down the midline, treat it as diastasis and rebuild your deep core before any crunches. If it feels like an even, soft layer, focus on gentle whole-body habits and patience. Most mums have a bit of both, so a core-first plan is the safest place to begin. Get clearance from your doctor or midwife before starting, usually around six weeks and later after a c-section, and see a women's health physio for a wide gap, a hernia or pain. Results vary, but the right starting point makes all the difference.
Frequently asked questions
Will losing weight get rid of my mum pooch?
If the pooch is mostly fat, losing weight gradually can help flatten it. But if there is also a diastasis recti, fat loss alone will not close the muscle gap. You may get leaner and still see a doming midline, which is the sign you need deep-core rebuilding rather than just dieting.
Can crunches fix a mum pooch?
Not if you have diastasis recti. Traditional crunches push pressure out against the weakened midline and can make the gap worse. Start with gentle deep-core breathing and progressive exercises that build tension safely, and only add harder ab work once your core can hold that tension.
How do I know if it is fat or diastasis recti?
Lie on your back, lift your head slightly, and feel along your midline above and below the belly button. Fat stays soft and even with no ridge. Diastasis shows as a gap with firmer walls either side, often with a dome popping up when you lift. When in doubt, a women's health physio can assess it properly.
When can I start working on my mum pooch?
Get clearance from your doctor or midwife first, usually around the six-week check and later if you had a c-section. After that you can begin gentle deep-core work. If you have pain, a wide or deep gap, or a bulge that worsens when you strain, see a women's health physio or your doctor before progressing.
