What Are the Best Exercises for Diastasis Recti?

What Is Diastasis Recti?

Before the exercises, a quick picture of what you’re working with, because it explains why the exercise order matters so much. The two halves of the “six-pack” muscle (the rectus abdominis) separate as the tissue between them stretches. Cleveland Clinic describes it as extremely common in pregnancy, and that’s the key reframe: it’s a normal adaptation your body makes to grow a baby, not something you caused. Good physical therapy during pregnancy can even prepare the core for it.

How the Linea Alba Stretches During Pregnancy

The band of connective tissue down the middle of your abdomen (the linea alba) thins and widens as the uterus grows. Three muscles matter for recovery, and one of them is the star:

The transversus abdominis works like a natural corset, which is exactly why the early exercises target it instead of the six-pack muscle everyone wants to train first.

Who Can Get Diastasis Recti?

Some separation is expected late in pregnancy, and it’s most common postpartum, but it isn’t only a pregnancy story:

Factors that make it more likely: twins or multiples, a larger baby, maternal age over 35, more than one pregnancy, and a smaller frame or shorter torso.

How to Check for Diastasis Recti at Home

Before starting exercises, it helps to know how to check for diastasis recti and get a general sense of your gap. One ground rule first:

Step-by-Step Finger-Width Self-Test

1. Lie on your back with knees bent and feet flat on the floor.
2. Place your fingertips just above your belly button, fingers pointing down toward your spine.
3. Gently lift your head and shoulders off the floor, as if starting a small crunch.
4. Feel for a gap between the two muscle ridges and note how many fingers fit.
5. Repeat below the belly button, then higher up toward the ribs, since the gap can sit at any of these levels.

Tissue tension is also part of the assessment; that’s next.

Gap Width vs. Tissue Tension: What Matters More

The width of the gap is not the whole story. Clinicians also check how firm the tissue feels when the core engages, since tension along the linea alba may affect how the core functions.

Signs Your Core Needs Attention

Diastasis recti isn’t just about how the belly looks; these signs suggest it’s affecting how your body works, and all of them are common and treatable:

• Doming or coning down the midline when you sit up
• A belly that still looks pregnant months after birth
• Lower back pain (our back pain treatment program sees this pairing constantly)
• Bladder leaks when coughing or jumping (see women’s bladder control)
• A feeling of weakness or instability in the trunk

Does Diastasis Recti Go Away on Its Own?

What Happens in the First 8 Weeks Postpartum

Tissues begin to recover after birth as hormones settle and the uterus shrinks. Gentle breathing, deep core activation, and walking are common early starting points for many people, and readiness depends on your delivery, any complications, and current symptoms. Follow your postpartum physical therapy guidance, and ask your provider if you’re unsure what’s right for you.

Why Some Cases Persist

Months or years later, a gap can still be hanging around for a handful of reasons:

• Multiple pregnancies. The tissue stretches again before it fully recovers.
• A C-section. Abdominal wall recovery takes a different path and often more time.
• Returning to crunches or heavy lifting too soon. Load before control re-opens the midline.
• Ongoing constipation and straining. Daily pressure spikes work against healing; pelvic floor therapy addresses this side.
• Low tension in the connective tissue. Some midlines simply need more guided support to firm up.

Realistic Recovery Timeline

Recovery varies from person to person, and published research following women through the first year after birth shows separation is very common early, improves for many, and persists for a meaningful share without targeted rehab. Frame recovery as improving core function rather than hitting a deadline:

Safe Exercises for Diastasis Recti

Here’s the core of the guide, and the key principle behind all of it: start with breath and deep core activation, add movement gradually, and stop any exercise that causes doming, pain, or leaking. These safe exercises for diastasis recti all work at home with no equipment; they’re the same postpartum core exercises we teach in the clinic.

1. Diaphragmatic (360°) Breathing

Targets: diaphragm and deep core. These breathing exercises for diastasis recti are the foundation, because breathing into the ribs, back, and belly teaches the diaphragm, pelvic floor, and deep core to work together.

1. Lie on your back with knees bent, hands on your lower ribs.
2. Breathe in so the ribs widen in every direction: front, sides, and back.
3. Exhale slowly and feel everything gently recoil.

2. Transverse Abdominis Activation

Targets: transversus abdominis, the deep muscle that supports the midline. This is the most important of the transverse abdominis exercises to get right.

1. Lie on your back with knees bent.
2. On an exhale, gently draw your lower belly in, like zipping up a snug pair of jeans.
3. Hold 5 to 10 seconds while breathing normally, then release.

3. Pelvic Tilts

Targets: deep core and lower back; builds control and can ease lower back stiffness.

1. Lying with knees bent, exhale and gently flatten your lower back into the floor.
2. Engage the deep core as you tilt.
3. Slowly release back to neutral.

4. Heel Slides

Targets: deep core and hip flexors; adds leg movement while the core stays stable.

1. Lying with knees bent, engage the deep core.
2. Slide one heel away along the floor, keeping the pelvis still.
3. Slide it back and switch sides.

5. Toe Taps (Supine Marching)

Targets: deep core; a step up in difficulty from heel slides.

1. Lift one bent leg to tabletop with the deep core engaged.
2. Lower it slowly to tap the floor, then return.
3. Alternate sides.

6. Glute Bridges With Core Engagement

Targets: glutes and deep core. Strong glutes support the pelvis and lower back during daily tasks like lifting a baby.

1. Lying with knees bent, exhale and engage the deep core and pelvic floor.
2. Lift your hips until your body forms a line from knees to shoulders.
3. Lower slowly with control.

7. Bird Dog

Targets: deep core, back, and glutes. This position loads the abdomen more, so it belongs later in the progression.

1. Start on hands and knees, spine neutral.
2. Extend the opposite arm and leg while keeping the trunk still.
3. Return with control and switch sides.

8. Modified Side Plank (Knees Down)

Targets: obliques, with less midline pressure than a front plank. The most advanced exercise on this list.

1. Lie on your side with knees bent, propped on your forearm.
2. Lift your hips so your body forms a line from knees to shoulders.
3. Hold, breathe, and lower with control.

How to Progress Your Diastasis Recti Exercises

Recovery moves in phases, and the rule for moving on is simple: progress only when the current phase feels easy with no doming, no pain, and no leaking. Doing too much too soon is the most common setback I see.

In Phase 3, the goal becomes a gradual return to everyday activities and workouts. Therapeutic Pilates guided by a physical therapist is a great bridge between rehab and regular fitness.

Exercises to Avoid With Diastasis Recti

Certain exercises push pressure against the stretched midline and can worsen doming, especially early in recovery. Think of these exercises to avoid with diastasis recti as “avoid for now, modify later,” not banned forever:

Crunches and sit-ups push pressure forward against the stretched midline and often cause doming. Many people try these first, which is exactly why they don’t see results. Full planks and push-ups place a high load on the abdominal wall; they come back later through the progression of wall plank, incline plank, knee plank, then full plank. Breath-holding under load spikes abdominal pressure, so practice “exhale as you lift” with the car seat, the stroller, the groceries, and the laundry basket. Deep backbends overstretch the front of the abdomen, and some loaded twists strain the midline; modified yoga or Pilates with a qualified instructor covers the same ground safely.

Everyday Habits That Support Recovery

Recovery happens outside workouts too, because your midline feels every lift, cough, and trip to the bathroom. Small daily habits reduce that strain all day long, and they pair naturally with your postpartum recovery plan:

When to See a Physical Therapist for Diastasis Recti

Home exercises carry many people all the way, and there are clear signals that diastasis recti physical therapy will get you further. You can book an assessment at any point; you don’t need to wait for a milestone.

Signs Home Exercises Aren’t Enough

What a PhysioFit Evaluation Includes

Your first visit is a private 1:1 session: a medical history, a posture and movement analysis, a measurement of the gap and tissue tension, and a check of the pelvic floor and core, since they work as one system. From there you leave with a plan matched to your body, as part of our broader women’s health services.

Can Physical Therapy Help You Avoid Surgery?

Physical therapy is a conservative option that may improve core function and symptoms. Surgery is considered for selected cases after medical evaluation, such as when function doesn’t improve with rehab or for cosmetic reasons, and no honest provider promises that PT replaces surgery for everyone.
