Diastasis is the term for the separation of parts of your body that are normally not separated.
One of the most common types of diastasis in the human body is diastasis recti, which is the separation of the rectus abdominis muscles—ab muscles that make up your core.
Your rectus abdominal muscles, which hold in your internal organs, run along your abdomen from your sternum to your pubic bone in two parallel bands. These muscle bands are connected by a bit of connective tissue in the middle called the linea alba. This connective tissue is where the separation occurs. All bodies have some separation due to the fact that the recti bellies are connected with this connective tissue. How wide this diastasis (or separation) determines if you need to modify your exercise routine for diastasis recti.
Diastasis recti can happen to anyone, including men, babies, and children. However, most cases occur in women due to pregnancy.
As your uterus grows during pregnancy, organs in your body move to make room for it. As your uterus expands outward, it adds pressure to the abdominal wall and stretches your abdominal muscles. If these muscles stretch enough to the point that they separate more than 2.5 centimeters along the linea alba, this is called diastasis recti.
With that many risk factors, it’s easy to see why 30 to 60% of pregnant women and postpartum women
experience this abdominal separation.
The symptoms of this condition can vary from woman to woman, so it’s important to understand what to look for if you’re pregnant or if you have recently given birth.
The most obvious symptom is a postpartum pooch around your ab muscles. However, that doesn’t always mean you have diastasis recti. It could indicate a weak transverse abdominis or weak core.
You might also think you have diastasis if your belly has a “bread loaf” or ridge or it cones as you roll to sit up.
You can do a self-check exercise at home after you’ve given birth to determine if you have diastasis recti.

It’s possible to improve diastasis recti by repairing and strengthening your deep core muscles through a variety of abdominal exercises specifically targeting your transverse abdominis (TA).
As mentioned above your rectus abdominis run along your abdomen in two parallel bands. These muscle bands are connected by a bit of connective tissue in the middle called the linea alba. Underneath lies the obliques and transverse abdominis. The transverse abodminis (TA) runs horizontal. Because these muscle fibers run horizontal, exercises dedicated to the transverse abdominis help approximate the rectus abdominis, which help to minimize the gap.
In your exercise, it’s important to avoid increasing pressure on your belly tissues, at least until you’ve created core stability. Until then avoid the following motions:
Some cases are severe enough that they require abdominoplasty (tummy tuck); however, in most cases, you can do specific exercises designed to help heal your muscle separation.
As we mentioned, traditional core moves like planks and crunches won’t work. Instead, you need to strengthen the deep abdominal muscles, with some ab-safe exercises. These include:
Find videos all of these exercises in our Diastasis Recti workout program.
We spend 12 hours a day upright, this is key time to keep your abdominal wall from being overstretched. With your feet parallel, stack your hip bone over your ankle bones. Stack your rib cage over your pelvis, careful not to flare the ribs. Breathe normally.
Do Kegel exercises. Hold for 5-10 seconds (you should be able to talk while you do these so you don’t hold your breath). And relax for 10 seconds. Do 10 contractions. Try to do these 10 to 20 times throughout the day. It is just as important to learn how to relax these muscles as it is to turn them on, so don’t skip that step!
Diaphragmatic breathing helps you take complete advantage of your lungs’ capacity. Lie on your back on a flat surface with your knees bent and fingertips placed inside your hip bones. Breathe in slowly through your nose, up into the diaphragm without flaring the rib cage/arching your back. As you exhale through the mouth with a “shhhh” sound, tighten your stomach muscles. You will feel this tightening of the transverse abdominis with your fingertips.
It’s important to incorporate safe strength training into your exercise routine. The Moms Into Fitness Diastasis Recti workouts have all been modified to be safe for those with diastasis recti, including flexibility, cardio, and strength training. Healthy (from toning) and supple (from stretching) muscles will treat you well!
Running puts additional pressure on your pelvic floor, which can exacerbate diastasis recti, incontinence, and pain, but there are ways to run safely. Wait six to eight weeks to begin running and take it slowly, spending two to three weeks on one distance at a time. Download our Ab Rehab Guide for more information on running with diastasis recti.
Diastasis recti is a core muscle issue, but it can affect the rest of your body. We have several arm exercises that will help you avoid added pressure on your abdominal muscles. For example, hold a dumbbell in both hands with your arms by your side and with your feet shoulder width apart. Then, bend your knees and push back like you’re going to sit in a chair; as you lower your body, raise your arms upward in a V position while keeping them straight. Then lower your arms and stand up straight again. Repeat these 15 times.
Squatting while doing a transverse abdominis breath is a good leg exercise. Begin by holding a towel or resistance loop in your hands with your feet shoulder width apart. Bend your knees, lean forward, and squat while keeping a flat back; as you squat, raise your arms and pull on the towel. This squat, in addition to our other leg exercises, is just part of our full three-phase diastasis recti workout program for strong legs.
While this condition is common, that doesn’t mean it is inevitable. Doing the following during pregnancy can reduce your risk of developing diastasis recti.
Avoid heavy lifting.
While you want to engage your core throughout pregnancy with approved exercises, excessively heavy lifting can lead to abdominal pressure and separation. If you have older children who want to be carried or your job requires heavy lifting, squat and engage your leg muscles. Wearing a maternity support belt can also take pressure off your abdomen.
Don’t focus too much on “traidtional” ab training during pregnancy.
Again, it’s important to engage your core but focusing too much on your abs can have the unintended effect of separating your abdominal muscles. Typically we recommend staying away from doing planks with Diastasis Recti but each case varies.
When you want to get up out of bed, try to avoid sitting straight up, which puts pressure on your abdominal muscles. Instead, roll over onto your side and use your arms to push yourself up.
