If you’ve noticed a soft bulge in your lower belly since having a baby, you’ve probably wondered whether it’s just a “mom pooch” or something more specific like diastasis recti. This distinction actually matters, since the right exercise approach differs significantly depending on which one you’re dealing with. This guide walks you through a simple at-home test and explains exactly what to do next.
What Is a Mom Pooch?
A mom pooch is a general term for the soft lower-belly bulge many women notice after pregnancy. It can result from stretched skin, weakened core muscles, postural changes, or simply the natural process of a body adjusting after carrying a baby for nine months. Importantly, it’s not a medical diagnosis it’s more of a descriptive, catch-all term.
What Is Diastasis Recti, Specifically?
Diastasis recti is a measurable separation of the two sides of the rectus abdominis (the “six-pack” muscle) along the midline of your stomach. According to NHS guidance, it’s extremely common during pregnancy, since your growing womb pushes the muscles apart, making them longer and weaker. Consequently, this separation usually returns closer to normal by around eight weeks after birth, though for some women, it persists for much longer.
Why the Distinction Matters
A general mom pooch might respond well to standard core exercises and consistent overall fat loss. However, diastasis recti requires a more careful approach, since traditional crunches and certain ab exercises can actually worsen the separation if attempted too early, before the muscles have had a chance to heal properly.
How to Check for Diastasis Recti at Home
Following NHS-recommended technique, you can check the size of your separation using this simple method:
- Lie on your back with your knees bent and feet flat on the floor
- Place two fingers just above your belly button
- Gently lift your head and shoulders slightly off the floor, as though starting a small sit-up
- Feel for a gap or soft dip between the two muscle bands beneath your fingers
- Repeat the check slightly above and below your belly button, since the gap can vary along the midline
What the Results Actually Mean
Generally, a gap of around two finger-widths is considered a normal degree of separation, particularly in the weeks immediately following birth. However, if the gap measures three finger-widths or more, or if you notice a visible “doming” or ridge running down your stomach when you strain, this suggests a more significant diastasis recti that’s worth discussing with a professional.
Signs It’s Diastasis Recti Rather Than “Just” a Pooch
- A visible doming or ridge appears down the middle of your stomach when sitting up or straining
- You can press your fingers into a noticeable gap along the midline
- You experience lower back pain or a persistent feeling of core weakness alongside the visible bulge
- The bulge becomes more pronounced during activities like coughing, lifting, or getting out of bed
Safe Exercises for Each Condition
If you’re dealing with a general mom pooch without significant separation, most standard core exercises are appropriate once you’re cleared for general activity. If diastasis recti is present, though, focus first on gentle, breathing-based deep-core activation, such as pelvic tilts and controlled breathing exercises, before gradually progressing to more demanding movements. Additionally, avoid traditional crunches, sit-ups, and full plank holds until a professional confirms your muscles are ready to handle that load safely.
When to See a Professional
If your gap remains wide after several weeks of gentle, correct exercise, or if you notice ongoing doming, contacting your GP for a referral to a women’s health physiotherapist is the recommended next step. They can properly assess the severity and build a tailored recovery plan specific to your body.
Frequently Asked Questions
Can diastasis recti heal without any treatment?
Often, yes for many women, the separation naturally improves within the first eight weeks after birth. However, correct, targeted exercise significantly improves outcomes compared to waiting alone, especially for larger separations.
Is it safe to exercise with diastasis recti?
Yes, but certain exercises need modifying. Gentle core activation is safe and beneficial, while traditional crunches and some plank variations should wait until a professional confirms it’s appropriate to progress.
How common is diastasis recti after pregnancy?
Extremely common. Most women experience some degree of separation during pregnancy, and it’s considered a normal, expected part of the process rather than something to worry about immediately.
Can men get diastasis recti too?
Yes, though it’s far less common. It can occur in men due to significant weight gain, improper lifting technique, or excessive abdominal strain over time.
Will a mom pooch go away without addressing diastasis recti first?
Not necessarily. If diastasis recti is the underlying cause, standard fat-loss efforts alone often won’t fully resolve the visible bulge, since it’s a muscular rather than purely fat-related issue.
Conclusion
Telling a mom pooch apart from diastasis recti comes down to one simple, reliable check you can do at home in under a minute. While a general pooch often responds to standard core training, true diastasis recti needs a gentler, more targeted approach to avoid making the separation worse. If you’re still unsure after testing, a women’s health physiotherapist can give you a proper diagnosis and personalised plan.
