Diastasis Recti, also known as Rectus Diastasis, is a separation of the rectus abdominis (otherwise known as the six-pack muscle). Diastasis means separation. Recti refers to your ab muscles called the rectus abdominis. This separation can happen during pregnancy and postpartum. Diastasis recti can occur in anybody. But since you happen to be on a website made for moms, we will be focusing on diastasis recti during pregnancy and after pregnancy.
Research has shown that at least 45% of moms have an abdominal separation (or diastasis recti) six months postpartum. Most don’t even know that it’s there until they experience a weak core, a belly they don’t like (i.e. the mommy tummy, muffin top or any other ugly name we call it!) and low back pain. It can get better with exercise, see our 4 MUST DO MOVES for diastasis recti BELOW.
What can happen as a result of an expanding belly during pregnancy is the distancing of the two sides of the rectus abdominis muscles. It creates a distance between your rectus abdonimis muscles into a left and right side and the muscles can no longer contract effectively.Diastasis Recti occurs in 33-60% of pregnant women.
You are more prone to this abdominal gap if you have a weaker abdominal wall, if you are carrying a large baby, if you are carrying more than one baby, if you have a narrow pelvis, if you have more than one child, if had them close together, or if you’re over 35 when you get pregnant.
After this long list of predisposing factors, you can see why this condition is prevalent.
That said our bodies are made to bear children and are also resilient in getting back to their prior self. There is less intra-abdominal pressure – as regain your former self, body fat decreases, baby is out and pressure is reduced.
We all have connective tissue between the recti belly muscles. We all have a gap or distance between our two recti muscles. A normal gap is 1-2 finger widths. I say gap or distance because I don’t want you to think these muscles are separated and will never get back together! If this gap is over 2.7 cm or two fingerwidths, it’s considered diastasis recti.
If you have this separation (or gap), do not worry it does not always mean you need surgery! But know that doing traditional ab exercises that load your abdominal wall (i.e. plank) can make it worse and not help it heal.
Important note: it cannot be assumed you have diastasis recti if your belly isn’t flattening after birth or a c-section…most of the time a distended belly is due to an under cued transverse abdominis or deep core musculature.
If you had a baby within the last 6 weeks, your body is not quite “normal” yet. Your blood volume, uterus size, diaphragm etc. still need time to return to their original size/place.
After having a baby it is essential you know how the transverse abdominis and pelvic floor can be recruited during exercise. It’s not your fault – it might have never been cued and our bodies always take the easy route. But it is essential for a healthy core!
So what should I do if I think I have diastasis recti?
It is always best to get a diagnosis with your doctor and let he/she guide you in healing this condition. It if is a mild case you can follow the 4 pointers we have listed below. Otherwise 1-1 attention with a physiotherapist or physical therapist will be the best route! He/she can correct your alignment, muscles imbalances and posture, as well as give you additional exercises and cues for a healthy core.

Stand with your feet parallel. Then stack your pelvis over your feet (not your toes!) Stack your rib cage over your pelvis. Or as I like to call it “close your ribs”. Don’t stand with a swayback and open rib cage. This exacerbates the pressure on the tissue where the distance occurs. The smallest of changes – closing the ribs and stacking the pelvis over the feet – takes pressure off that tissue (linea alba). *note: as you “close” your rib cage be careful that you do not tuck your pelvis.
You will want to correct your posture in everyday activity – sitting, standing, walking, exercising, etc. Watch this quick 60 second video on correcting your posture!
You should start with training the pelvic floor and transverse abdominis –this will create a healthy core without adding pressure to the belly tissues. You will find exercises like these in our Diastasis Recti program (try it totally free!)
Of course you want your core to be healthy. But I am willing to bet you are also after the cosmetic reason – the flattening of your stomach. Your body (specifically your abdominal wall) was made to carry a baby. But diastasis recti doesn’t always resolve itself on its own after the baby is born. As you regain your former self, body fat decreases, your uterus returns to its normal size and the intra-abdominal pressure decreases on the abdominal wall.
Pelvic Floor Activation – This is important for every mom! Act as though you are stopping the flow of urine or contracting your anus, hold for 10 seconds and release. Repeat 10-20x. The pelvic floor is not meant to be “turned on” all day.
Transverse Abdominis (TA) Breath – Start by taking a deep breath. No, seriously, I mean it. Take a deep breath. What happened to your upper body when you did that? If your chest expanded and your shoulders rose, then you aren’t breathing properly. Don’t be ashamed: most of us don’t breathe correctly all the time. What we fail to do is to use our diaphragms to take advantage of more of our lung’s capacity.
Try it this way to make sure you are using your core breath at it’s full capacity.
When you first learn the TA breath, it’ll be easier for you to follow the instructions lying down. When you get better at it, you can try while sitting in a chair. Repeat the same steps as above. You can also do this while standing and while exercising.
We have an entire page dedicated to the transverse abdominis if you want to more info;)
These are some general guidelines. If you want a comprehensive routine and program, click here for Diastasis Recti program.
Overall what we see is non-exercising women don’t usually see improvement in the recti distance, while exercising women better theirs. As you incorporate strength training and cardiovascular exercise it is important you don’t load the abs. For example, if you are in a hinged position performing rows, your abdominal wall is loaded. You can see a list of the dos’ and don’t of diastasis recti below. Overall you will want to use a comprehensive workout that does not load the abs. If you are not working with a physiotherapist or physical therapist I recommend using our Diastasis Recti program– all workouts in these programs are modified for diastasis recti.
Meet Jenn, a mom who didn’t discover her own mild diastasis until she was over 5 years postpartum! In this video, Megan, a Physical Therapist, shows how and where to find an abdominal separation:
There is no universal list of don’ts in the diastasis recti world. But because it is usually the intra-abdominal pressure that causes the recti muscles to have a bigger gap between them, we usually stay away from applying extra intra-abdominal pressure.
You should refrain from twisting. We also recommend you don’t do planks, push ups, quadruped positions, crunches and traditional abdominal exercises that can create extra pressure on the condition. Most traditional abdominal exercises are not recommended, at least until your TA can stabilize your torso and your muscles are firing effectively.
Note there was a study done in 2015 found that a crunch reduced the distance of the rectus, but the research noted it requires more study on exercises to explore effect of ab training. Planks can be a great exercise, but only recommended when working closely with a physical therapist or physiotherapist or when the condition has improved.
Overall your diastasis is unique to you. And it’s important you functionally move throughout the day by activating your transverse abdominis. Exercise is a minimal part of your day, the other 23.5 hours a day count too!
