What is diastasis recti?
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 stick around after the baby is born. Most of the time it happens later in pregnancy, and usually occurs with bigger babies or with multiple pregnancies close together. It is not harmful and it sometimes goes away after the baby is out and there is no more intra abdominal pressure.
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.
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. In a study done with 300 women, about 45% of these moms had a mild case at 6 months postpartum.
Diastasis Recti occurs in 33-60% of pregnant women. 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.
If you recently had a baby you will want to also read about postpartum recovery, the first 8 weeks.
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. 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!
What should I do if I have this condition?
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.
How can I test for diastasis recti?
This video is a general self test for diastasis recti. Diastasis Recti is a medical condition and should be diagnosed by a doctor. This condition can be grouped into 3 types, and depending on the severity, some cases can be healed with exercises modified for diastasis recti.
Mild Case – 2-3 fingerwidths
Moderate -3-4 fingerwidths
Severe – 4+ fingerwidths
4 Pointers to improve Diastasis
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 15 second video on correcting your posture!
#2 Exercises for Diastasis Recti
You should start with training the pelvic floor and transverse abdominis – see exercises below.
Diastasis Recti can cause low back pain and/or pelvic pain, but some studies show this pain is present with and without diastasis recti. The goal is a healthy core, a healthy gait (or the way you walk) and a healthy posture. Since all of our systems work together, you should do more than just training your core – which we get into in the next point.
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 and so does the pressure on the abdominal wall.
But just how do we get a flat stomach again?
*Note you can have a flat stomach and have diastasis recti. So distended bellies does not equal diastasis recti – as we mentioned in the first part.
I am going to refer to three separate studies as well as anecdotal or case studies in the past 12 years. Please know there is no industry standard. Until recently there was very little research and women are usually referred to a Physical Therapist or Physiotherapist (which I still recommend, especially in severe cases).
Isometric work with the transverse abdomins as well as overall strength training and cardiovascular exercise have proven to eliminate diastasis recti. We will be concentrating on 4 exercises to work your transverse abdominis.
We do several of these movements in our Love Your Body program.
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 meant 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.
This diaphragm stuff is important, hang on tight…
Now that you know about the diaphragm, please know it is a key element to a healthy core. As we move through this TA breath I want you to make sure you are using your core breath at it’s full capacity.
- Lie on your back on a flat surface or in bed, with your knees bent. Place one hand on your belly. This will allow you to feel your diaphragm move as you breathe.
- Breathe in slowly through your nose so that your stomach moves out against your hand.
- As you exhale through pursed lips tighten your stomach muscles, letting them fall inward. Try to keep your chest still, this move comes from the belly and lower rib cage.
Pregnant? Check out the Pregnancy transverse abdominis breath.
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. For me, I learn by watching and following examples. So I made this :45 second video with demonstration:
We have an entire page dedicated to the transverse abdominis if you want to more info;)
Isometric Arm Switch – as you perform the TA breath, move your arms overhead, then switch. Careful not to shrug your shoulders. The only movement is in the arms and the belly (as you inhale your belly rises, and as you exhale your belly falls to activate the TA). Repeat 15-20x.
It’s important that you keep your transverse abdominis engaged and core neutral…what do I mean by neutral? Don’t tuck your or tilt your pelvis & keep your spine neutral. This means there might be a space between your lower back and the floor, but you should not arch your back.
Bridge – as you perform a bridge keep your core neutral, TA is engaged. It’s important your hips stay level so you do not add any strain on the abdominal wall. Be careful as not to arch your back … go into a bridge with a flat back. Repeat slowly 15-20x.
Isometric Heel Slide – this image shows a more advanced version, you will want to start out with your arms to your sides. Perform the TA breath as you slide your heel in and out. Again it is important you keep your core neutral as mentioned above. Repeat 10-15x.
You can do these exercises daily. The most convenient time is bedtime!
These are some general guidelines. If you want to know more we cover diastasis recti more extensively in my Prenatal & Postnatal Specialist certification.
#3 Daily Strength Training
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 Postnatal SlimDown program or Love Your Body program – all workouts in this program are modified for diastasis recti.
#4 The Don’ts
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 most traditional abdominal exercises that can create extra pressure on the condition.
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.
Moms Into Fitness is not a medical facility. All exercises should be discussed with your doctor prior to exercise.
