Lose Your Mummy Tummy–Diastasis Recti & Why Crunches are BAD for You

If you have a “mummy tummy” or “mummy pooch” or basically you feel like you look pregnant (or others think you are) when you're not, this post is for you.
You're likely tempted to do lots of crunches, but actually, they might not be a help. And they might hurt you.
What you likely have is diastasis recti. Here's more about it and what you can do to help your body get back to normal.

Have you ever heard of Diastasis Recti?
Having a “mummy tummy” isn't fun, but it's about more than just how you look.
I mean, being attractive is good for your mental and emotional health, but there is more going on here.
My Personal Diastasis Recti Story
Having worked in the fitness industry for 18 years, one common complaint I've heard from many postpartum moms is that their bellies seem to get BIGGER– not smaller–the more they work their core.
Before I had kids myself, I was a personal trainer, and I just told these unsatisfied customers to accept that some new curves would always be a part of the blessing of motherhood. Then I got pregnant three times myself, and let me just tell you what happened:
- My first pregnancy ended in a miscarriage at 11 weeks, and I wondered why my abs didn't go back to flat when I had barely even been showing.
- Six months later, we conceived my daughter. After I gave birth to her, I wondered why my tummy got flat right after having her, but then pooched out when I started exercising again.
- Three years after having my daughter, I had my son, and my belly didn't even attempt get flatter no matter how many crunches and planks and cardio sessions I did. In fact, he was over 2 years old when I realized my stomach was still making an inverted V-shape whenever I sat up.Yet I was doing core work almost every day. It was the kind of core work I was doing (crunches, situps, planks) that was making my belly rip more!
Women all over the world are reading those three pieces of my personal history and nodding their heads, because our physiology is the same and most of us have experienced this… and accepted it?
A Mummy Tummy Isn't Normal
Yes, we've been told by personal trainers who've never had kids (like I was) that it's normal to have a mummy tummy.
Once I finally realized that my certification as a group fitness instructor and my degree in Exercise and Sport Science from Oregon State University had left out some important information about how a woman's core works during and after pregnancy,
I went in search of exercises that truly help minimize and treat diastasis recti (Diastasis Recti Abdominus–a split in your abs that’s wider than normal).
In the July 1988 issue of Physical Therapy, an abstract was published that showed EVERY pregnant woman's abs splitting into a diastasis in the 2nd trimester of pregnancy. “
Its incidence peaked in the third trimester group; remained high in the women in the immediate postpartum group; and declined, but did not disappear, in the later postpartum group. These findings demonstrate the importance of testing for diastasis recti abdominis above, below, and at the umbilicus throughout and after the childbearing year.”
But have you ever been checked for diastasis recti? Has anyone ever told you which exercises help it and which ones make it worse?
Diastasis Recti Leads to Other Problems
Has anyone ever explained how the wider your gap is, the more your lower back, digestion, pelvic floor health, and many more problems will increase?
In fact, diastasis recti is a direct cause of back pain–this post on diastasis recti and back pain goes into more detail.
Because if your abdominal wall isn't holding your innards in the right spots, then your innards won't work as well… ding! Lightbulbs going off in heads all over the world!
I now believe that if every woman could learn the following four do's and don'ts for reclaiming their cores, then we'd have far fewer pregnant-looking grandmothers out there.
Because that is what is happening with traditional core work: the stress of crunches and planks and situps upon injured abdominals just stresses the connective tissue more!
If you follow these 4 exercise tips, you can start healing your core for good, no matter how many months or years postpartum you are…

4 Exercises for Diastasis Recti to Ditch Mummy Tummy
Train Your Transverse Abdominus
Your TA is your own natural girdle, assisting the uterus with expulsion during birth and taking pressure off your healing six-pack (rectus abdominus) after birth.But the obliques and six-pack get so much attention in the fitness industry that many women don't even know about their bigger, deeper, more important TA muscle.
You can start activating your TA three days after vaginal birth and 10 days after surgical birth. Learn how by clicking HERE to watch my 10-minute “Totally Transverse” workout!
Walk! Walk! Walk!
Nothing is more effective at working your whole body in a safe, effective, gentle manner than walking. Walking naturally stretches and flexes your pelvic floor and activates your whole core without stressing your abdominal connective tissue.
If you use a baby carrier, please make sure that it's one that prevents hip dysplasia in the baby while supporting your core without yanking on your back – wraps and ergo-like carriers are best. If you are pushing your child in a stroller, your form matters!
Read this incredible article about how to push a stroller with good posture by Lorraine Scapens of Pregnancy Exercise in New Zealand.
Practice Perfect Posture
Visualize the inside of your torso like two bowls; your pelvis forms one bowl, and your ribs form another upside down bowl. While sitting and standing, your rib bowl and pelvic bowl need to center with each other.
If your ribs are thrust forward, that stretches the diastasis, so pull your ribs down while keeping your spine tall. If your pelvic bowl is tilted so your hips are tucked under a lot, or so that your lower back is severely arched, that will also yank on your connective tissue.
Can the Crunches
Yes, I know this flies in the face of all those cute pictures of moms crunching up to play “peek-a-boo” with their baby floating on their shins.But crunches bulge the belly, not flatten it.If doing 300 crunches a day worked, you'd have a flat belly by now.
Sit ups are even worse, in fact, any crunch-like motion – this includes anything where the shoulders come off the floor – contributes to diastasis by very nature of biomechanics. (Yikes! I've been adding these to my exercise regimen recently. :(.)Planks are also inadvisable until while your diastasis recti is still open because of the gravitational pressure pushing down and out on your damaged core.
In Short, You Have Only One Body
If your hurt it, you cannot trade it in for a new one, and replacement parts are very expensive. If your workout makes you hurt more or “shreds” your belly apart to the point that your abs can't even hold your own guts in (that's not a beer belly, it's a diastasis, dude!) then your workout isn't improving your health; it's ruining your health.
Fitness should be a fun time of healing and re-energizing your body so that you can be a better mom, partner and volunteer. Don't settle for a broken body.

Thanks for sharing
Did you ever add before and after comparisons? I’m 3 weeks in to a life style change for fitness. I’ve lost 6 pounds of my 14 pound weight loss goal and 4% body fat but my stomach has not budged. Not even millimeters of change despite the numbers saying that I should be seeing change. I feel better. So that’s fantastic. But I’m pretty sure it’s never leaving.
Hi there – thanks for reading. I just put a before and after back in there. It’s not me but it’s a valid photo of someone who took one of the courses mentioned in the post. Hope that helps. Don’t give up!
Thanks for the good post towards fitness, especially for women.
With 7 babies and #8 on the way, I know about DR!!! I was in so much pain after my 5th baby and I’m grateful that all I was able to learn then. I really appreciate you sharing so much in this article because there are things that took me so long to learn – like walking really does make a big difference (in so many ways) and that there are ways a busy mama can add DR care into her day. I hope that crunches get taken out of workouts, too. I noticed crunches are in the Presidential Fitness challenge which is being taught to kids – I have been having my kiddos substitute something else – no need to set up them up for diastasis issues!!! Thanks again for sharing the great info.
You are so welcome!!
I suffer terribly with bloating, which as a young(ish) mum, is something I find terribly hard to live with, I dislike feeling uncomfortable in my own skin, adding clothes into this equation is almost unbearable. So a colon cleanse is probably a good thing for me to try. I ordered the Dr. Max Powers 15 Day Cleanse Capsules on the understanding that they are all high quality ingredients and quite natural, too.
I took as diretced for 15 Days, and the bloating has gone down. You do go to the bathroom a lot in the beginning but that is the toxin elimination. It feels good.
Hi, after having 3 babies, my Diastasis is huge! i can stick all four fingers in there! I haven’t stopped ‘looking’ pregnant since having my first which is almost 5 years ago now. My question is, will the totally transverse exercises really make my stomach look flatter? I have been doing those exercises for a while as well as other post-natal exercises, but they don’t seem to fix the problem, just help it a little. Do I just need to be more patient and keep exercising or am I unfixable? I’m so frustrated and tried of the weakness and lower back pain.
Hi Susan. I will email you. I am looking at a new plan. Well, I will leave the info here as well – I’m just not totally on board yet. I need to interview them and try the method but it sounds promising. https://www.wholewomanstore.com/?AffId=6 (that’s an affiliate link). I would be interested in what you think.
I went through the information on the wholewoman website, it seems very informative and helpful; however I don’t think its relative to my situation. I don’t have prolapses (as far as I know) and i don’t have any other problems other than back weakness and a diastasis above my belly button. The exercises I have been doing seem to help strengthen my core and back, but don’t seem to be closing the gap. Maybe I just have to keep it up and have more patience, but i was wondering if there ever is a situation where the diastasis is too ‘far gone’ and severe and surgery is necessary. Thanks for replying!
Hi there.
I just heard back from them (at the site) – they said to take a look at these products.
(the products appear to have new names—so just look at the store to see options)
Im 3 weeks postpartum can i star doing this?
Hi Heidi,
I just happened to be online for a brief bit on this sunny Sunday afternoon where I’m at, and I saw your comment! The foundational five starting routines from Fit2B have been midwife-approved and physical therapist-approved for use as early as 3 days post vaginal birth or 10 days post-surgical/cesarean. They are simply and lay the foundation for harder workouts later which I progress you towards. We just put out an ecourse built around the “F5” as we call them. You can find the course here > https://fit2b.us/shop and preview those routines here > https://fit2b.us/start-here … Once you join, there is a private member forum with lots of support!
Hi there. Just wanted to say thanks for all the good information and advice you post on your wonderful blog. Blessings.
You are so welcome. Thanks for the kind words. Sorry for the delay in responding. I’ve been swamped and am sick now :(.
