A Beginner's Guide to Healing Diastasis Recti

Last updated: | Medically reviewed by Dr. Isabella Rossi, PT, DPT, PRPC

Key Takeaways

  • Diastasis Recti is a separation of the outermost abdominal muscles, common after pregnancy, caused by the stretching of connective tissue.
  • Avoid crunches, sit-ups, and intense frontal planks, as these can put pressure on the midline and worsen the separation.
  • Healing focuses on rebuilding tension by activating the deep core muscles (TVA) with coordinated breathing and gentle exercises.

The Postpartum Pooch: It’s Not What You Think

Months or even years after giving birth, you look in the mirror and see that your abdomen still looks… different. There might be a persistent bulge, a “pooch” that no amount of dieting or exercise seems to touch. When you try to do a sit-up, you might notice a strange coning or doming shape down the midline of your stomach. This is the hallmark sign of Diastasis Recti, and it’s far more than a cosmetic issue.

Diastasis Recti is a separation of the rectus abdominis muscles (your “six-pack” muscles). It’s an incredibly common result of pregnancy, affecting a majority of women. It’s not a sign of failure or that you’re “broken”; it’s a natural adaptation your body made to accommodate your growing baby. However, when this separation doesn’t heal on its own, it can lead to a host of functional problems, including core weakness, nagging low back pain, and even pelvic floor dysfunction.

The good news is that with the right knowledge and exercises, you can safely and effectively heal your core. This guide will teach you how to check for diastasis recti, what exercises to avoid, and the foundational techniques to rebuild a strong, functional, and confident core.

What Exactly is Diastasis Recti?

Imagine your two rectus abdominis muscles as two pillars running vertically down the front of your abdomen. They are joined together by a strong, fibrous band of connective tissue called the linea alba. During pregnancy, a combination of hormonal changes (which soften connective tissue) and the physical pressure of the growing uterus causes the linea alba to stretch sideways, allowing the two muscle pillars to separate.

This separation is normal and necessary. The problem arises when, after delivery, the linea alba remains overstretched and lax, and the muscles don’t return to their original position. The key thing to understand is that diastasis recti is not a “hole” in your stomach; it’s a problem of impaired tension in the connective tissue. The goal of healing is not just to close the gap, but to restore the integrity and tension of the linea alba so it can effectively transfer force and support your core.

How to Check for Diastasis Recti at Home

You can perform a simple self-check to assess your abdominal wall. It’s best to do this when your muscles are relaxed.

  1. Lie on your back with your knees bent and your feet flat on the floor.
  2. Place your fingertips (pointing towards your toes) on your midline at your belly button.
  3. Gently lift your head and shoulders off the floor, just enough to feel your abdominal muscles engage. Don’t do a full sit-up.
  4. Feel for the Gap: As your muscles tense, you will feel the firm edges of your rectus abdominis muscles on either side of your fingers. Assess two things:
    • The Width: How many fingers can you fit horizontally in the gap between the muscles? A gap of more than two finger-widths is typically considered a diastasis.
    • The Depth/Tension: More importantly, what does the tissue under your fingers feel like? Is it firm and springy like a trampoline, or is it soft and deep, like you can sink your fingers in easily? A lack of tension is a key indicator that the core needs rehabilitation.
  5. Check in Multiple Locations: Repeat the check a few inches above your belly button and a few inches below it, as the separation can vary along the midline.

The #1 Rule: What NOT to Do with Diastasis Recti

Before we talk about what to do, it’s critical to understand what to avoid. Performing the wrong exercises can increase intra-abdominal pressure and actually make the separation worse.

Avoid any exercise that causes your abdomen to “cone” or “dome.” This includes:

  • Traditional crunches and sit-ups
  • Full frontal planks (initially)
  • Double leg lifts
  • Any movement that causes you to hold your breath and bear down.

This coning is a visual sign that the pressure inside your core is too great for the weakened linea alba to handle, and it’s bulging outwards.

Healing Your Core: The Foundational Steps

Healing diastasis recti is about rebuilding your deep core from the inside out. It starts with reconnecting your brain to the right muscles and coordinating them with your breath.

1. Re-establish the Breath-Core Connection

As we’ve discussed in our other articles, the foundation is diaphragmatic breathing. When you inhale, your belly should expand and your pelvic floor should relax. When you exhale, your belly should gently draw in and your pelvic floor should lift. This is the natural rhythm that engages your deep core, including the all-important Transverse Abdominis (TVA).

2. Activate Your Transverse Abdominis (TVA)

The TVA is your body’s natural corset and the key to healing diastasis. Its job is to create tension across the linea alba, which helps to bring the two sides of the rectus abdominis closer together. The best way to activate it is on the exhale. As you breathe out, gently draw your lower belly button in towards your spine without moving your pelvis or rib cage.

3. Start with Core-Safe Exercises

Once you’ve re-established the breath and TVA connection, you can begin to integrate it into gentle, safe movements.

  • Heel Slides: Lie on your back with knees bent. Exhale to engage your TVA, then slowly slide one heel away from you until your leg is straight. Inhale as you slide it back. The goal is to keep your torso perfectly still.
  • Bent Knee Fallouts: Lie on your back with knees bent. Exhale to engage your TVA, then slowly let one knee fall out to the side, keeping your pelvis level. Inhale as you bring it back to the center.
  • Glute Bridges: Lie on your back with knees bent. Exhale, engage your TVA, and lift your hips off the floor by squeezing your glutes. Inhale as you lower with control.

By focusing on these deep, stabilizing exercises, you are teaching your core to function as an integrated system again. You are rebuilding the tension in your midline, which not only helps to close the gap but also restores the strength and stability you need to move through life with confidence.

Frequently Asked Questions

How long does it take to heal diastasis recti?

Healing time varies greatly depending on the severity of the separation, consistency of exercise, and individual factors. Many people see significant improvement in function and appearance within 8-12 weeks of starting a consistent, appropriate exercise program. For some, it may take longer to fully restore tension.

Can I heal diastasis recti years after pregnancy?

Yes, absolutely. It is never too late to improve the function and strength of your core. While the connective tissue may be less responsive than in the early postpartum period, a targeted program focusing on TVA activation and pressure management can still lead to significant improvements in the gap's tension and your core's stability.

Is surgery the only way to fix a severe diastasis?

Surgery (an abdominoplasty or 'tummy tuck') is an option for severe cases where the connective tissue is significantly damaged and doesn't respond to physical therapy. However, it is almost always recommended to complete a comprehensive pelvic health physical therapy program first, as many people can restore full function and greatly improve appearance without surgery.

What's the difference between the 'gap' and the 'tension'?

This is a critical distinction. The width of the gap (measured in finger-widths) is less important than the tension of the linea alba (the connective tissue). You can have a 2-finger gap with firm, springy tension underneath, which is very functional. The goal of rehab is to restore that tension, which in turn helps to narrow the gap.

Can men get diastasis recti?

Yes. While it's most common in postpartum women, men can also develop diastasis recti. It's often caused by improper exercise techniques (like high-pressure weightlifting), rapid weight fluctuations, or genetics. The healing principles of focusing on deep core activation are the same.

Is it safe to run with diastasis recti?

It's generally recommended to wait until you have rebuilt foundational core strength and can manage intra-abdominal pressure well before returning to high-impact activities like running. Running with an unmanaged diastasis can put excessive strain on the weakened midline. It's best to get clearance from a pelvic health physical therapist.

Why does my stomach 'cone' or 'dome' when I try to sit up?

That 'coning' shape is the classic sign of diastasis recti. It's what happens when intra-abdominal pressure pushes out through the weakened linea alba connective tissue. Seeing this is a clear signal that the exercise you are doing is creating too much pressure for your core to handle at its current strength level.
