Diastasis recti can improve significantly with targeted exercises, but it takes consistency and patience. Most people see major improvement within 6 to 9 months of dedicated work, though the full recovery window ranges from 3 to 12 months depending on severity. The key is retraining the deepest layer of your abdominal muscles while avoiding movements that push the gap wider.
What’s Actually Happening in Your Abdomen
During pregnancy, the two halves of your “six-pack” muscle separate along the midline to make room for your growing baby. The connective tissue between them, called the linea alba, stretches and thins. After delivery, that tissue needs to regain tension and stiffness to hold your abdominal wall together again. Diastasis recti is generally defined as a gap of 2 centimeters or more between the muscle halves.
The separation itself isn’t a tear. It’s a stretching problem, which means recovery is about gradually restoring tension to that connective tissue while rebuilding the deep core muscles that support it. Movements that increase outward pressure on your abdomen (like straining to lift something heavy or doing a crunch) work against this process by pushing the gap apart instead of drawing it together.
The Exercises That Actually Help
First-line treatment for diastasis recti is physical therapy focused on strengthening the abdominal wall, and the most important muscle to target is the transverse abdominis. This is your deepest abdominal layer. It wraps around your torso like a corset and acts as a natural stabilizer for your spine and pelvis. Reactivating it is the foundation of recovery.
Abdominal Bracing
This is the starting point. Lie on your back with your knees bent and feet flat on the floor. Rest your arms by your sides. Take a deep breath in, and as you exhale, contract your abdominal muscles by imagining you’re drawing your belly button toward your spine. Hold that contraction for a few seconds while breathing normally, then relax on your next inhale. Repeat for several rounds.
It sounds simple, and it is. That’s by design. This gentle activation lays the groundwork for everything else by teaching your brain to engage the transverse abdominis again after months of it being stretched out. Once this feels natural, you can progress to more challenging variations: adding leg slides, heel taps, or single-leg extensions while maintaining that deep abdominal contraction.
Progressing Safely
The general principle is to start with exercises where your back is supported (lying down), then gradually move to seated, standing, and eventually more dynamic movements. At every stage, the goal is the same: keep your deep core engaged and avoid letting your belly bulge or “dome” outward during the movement. If you see a ridge or cone shape forming along your midline while exercising, that movement is too advanced for now.
A pelvic floor physical therapist can assess your specific gap width, test how well the tissue is generating tension, and build a progression plan tailored to where you are. This is especially worthwhile if you’re unsure whether you’re activating the right muscles or if your gap is wider than a couple of finger-widths.
Exercises and Movements to Avoid
Certain common exercises push your abdominal contents outward and can widen the separation or prevent healing. Until your gap has closed or your therapist clears you, avoid:
- Crunches or sit-ups of any kind
- Standard planks and push-ups (modified versions with knees down may be acceptable later)
- Double leg lifts and scissors
- Yoga poses like downward dog and boat pose
- Any exercise that causes visible bulging, coning, or doming along your midline
This doesn’t just apply to formal workouts. Daily activities matter too. Lifting grocery bags, picking up toddlers, and even getting out of bed by sitting straight up all create the same kind of outward abdominal pressure. Roll to your side before sitting up. Exhale and brace your core before lifting anything. In the early months, try not to lift anything heavier than your baby.
How Long Recovery Takes
Non-surgical recovery typically takes 3 to 12 months, with most people noticing significant improvement in the 6 to 9 month range. Several factors affect your timeline: how wide the gap is, how many pregnancies you’ve had, how consistently you do your exercises, and your individual tissue quality.
Progress can feel slow at first because the early exercises are subtle. You’re retraining a muscle that’s been dormant, and connective tissue remodels much more slowly than muscle strengthens. But the improvements compound. Many people notice functional changes (less back pain, better posture, a feeling of more support through their midsection) well before the gap itself measurably narrows.
When Surgery Becomes an Option
Exercise-based recovery works for many people, but not everyone. When diastasis recti doesn’t respond to months of consistent physical therapy, surgical repair may be appropriate. There’s no single gap measurement that automatically qualifies you for surgery. The decision depends on your symptoms, how much the separation affects your daily life, and whether conservative treatment has plateaued.
The most common surgical approach is a form of abdominoplasty where the separated muscles are stitched back together along the midline. Minimally invasive options also exist, though they aren’t suitable for everyone. Factors like excess skin, significant subcutaneous fat, or prior abdominal surgery can limit which techniques a surgeon will use. If you’ve been doing targeted exercises for 6 months or more without meaningful progress, a consultation with a surgeon who specializes in abdominal wall repair can help you understand your options.
Everyday Habits That Support Healing
Recovery doesn’t happen only during exercise sessions. How you move through your day has a real impact on whether the tissue is healing or being repeatedly stressed. When you stand up from a chair, brace your core first. When you cough or sneeze, place a hand over your abdomen for gentle support. When you carry your baby, hold them close to your body rather than on one hip, which creates asymmetric strain.
Posture plays a role too. Standing with your ribs flared out and your pelvis tipped forward (a common postpartum posture from months of compensating for a growing belly) keeps constant outward pressure on the linea alba. Gently stacking your ribcage over your pelvis and relaxing your lower back into a more neutral position reduces that load throughout the day. These small adjustments add up over weeks and months, giving the connective tissue a better environment to heal.
