Diastasis recti heals on its own for many women, but a significant number need targeted rehabilitation to close the gap. About 60% of women have a measurable separation at six weeks postpartum, and that number drops to roughly 33% by 12 months, meaning one in three women still has the condition a full year after delivery. If you’re in that group, or if your separation is wide enough to cause functional problems, a combination of specific core exercises, movement modifications, and patience is the most effective path forward.
What’s Actually Happening in Your Abdomen
Diastasis recti is a stretching and thinning of the connective tissue (called the linea alba) that runs down the center of your abdomen between the two halves of your “six-pack” muscle. During pregnancy, hormonal changes soften this tissue while the growing uterus pushes the muscles apart. The result is a gap you can often feel with your fingers when you lie on your back and lift your head slightly. A separation wider than about two finger-widths is generally considered diastasis recti.
The condition isn’t just cosmetic. That connective tissue is part of the system that transfers force across your trunk, stabilizes your spine, and supports your organs. When it’s compromised, you may notice a belly “pooch” that doesn’t respond to exercise, lower back pain, difficulty lifting things, or a visible bulge or “coning” along your midline when you strain.
The Link to Your Pelvic Floor
Your deep core muscles and your pelvic floor work as a unit. Research on postpartum women found a weak but statistically significant correlation between diastasis recti and stress urinary incontinence, meaning women with a wider separation were somewhat more likely to leak urine during coughing, sneezing, or jumping. The same study found that women with diastasis recti tended to have slightly weaker pelvic floor muscles in both strength and endurance.
This matters for rehab because you can’t effectively train one without the other. Strengthening the trunk wall requires coordinating your breathing, your deep abdominal muscles, and your pelvic floor together. If you’re experiencing any pelvic floor symptoms alongside your diastasis, addressing both simultaneously tends to produce better results than focusing on the gap alone.
Exercises That Help
The most commonly prescribed rehabilitation exercises include abdominal drawing-in (pulling your belly button gently toward your spine), breath-focused core activation, and what are sometimes called hypopressive exercises, which use specific breathing patterns to create a gentle lift in the pelvic floor and a drawing-in of the abdomen. These all target the deepest layer of abdominal muscle, which acts like a corset wrapping around your midsection.
A typical starting point looks like this: lying on your back with knees bent, exhale slowly while gently drawing your lower abdomen inward. You’re not sucking in your stomach. You’re activating the deep muscle that wraps around your trunk. Hold for 5 to 10 seconds while breathing normally, then release. Progressing from there involves adding limb movements (like slowly sliding one heel away from you while maintaining activation), then eventually moving to hands-and-knees positions, standing exercises, and modified planks.
It’s worth noting that the research on these exercises shows inconsistent results. Some studies find meaningful gap reduction, others don’t. Several researchers have pointed out that measuring only the width of the gap may not capture the full picture. The tissue between the muscles can become firmer and more functional even if the gap doesn’t fully close, which means you can regain core strength and stability without necessarily achieving a zero-width separation. A rehabilitation program supervised by a pelvic floor physiotherapist tends to produce the best outcomes because they can assess your specific pattern and progress you appropriately.
Exercises to Avoid
Any movement that forces your abdominal wall to bulge outward, creates visible coning along your midline, or pushes downward on your pelvic floor can worsen diastasis recti. The general rule: if you see a ridge or dome forming along the center of your belly during an exercise, stop.
Specific exercises to skip or modify until your core can handle them:
- Traditional crunches, sit-ups, and bicycle crunches. Lifting both shoulders off the floor from a back-lying position puts direct outward pressure on the separation.
- Double leg lifts. Lifting both legs simultaneously from your back creates intense intra-abdominal pressure.
- Standard planks and push-ups. The load on the front of the core is often too much early in recovery.
- High-impact cardio like running, jumping, and rebounding, which repeatedly spike pressure in the abdomen.
- Deep backbends including full wheel, full cobra, and full upward-facing dog in yoga.
Several Pilates movements are also problematic, including the Hundreds, Roll Up, Teaser, and Corkscrew. These aren’t permanently off-limits. Many women return to all of these activities once their core has rebuilt enough strength and control. The key is reintroducing them gradually and watching for coning or pressure symptoms.
Do Abdominal Binders Actually Help?
Abdominal binders and support garments are popular, but the evidence for them is thin. In one study, women who wore a compression garment or a rigid belt saw their diastasis reduce by about 46% over eight weeks, but there was no significant difference between the groups or compared to natural healing alone. The amount of time women wore the support had no correlation with how much the gap closed.
Another trial found that an exercise-only group reduced their separation by 34% over six weeks, while a binder-only group managed just 18%. A separate pilot study comparing a binder group to a control group over 12 weeks found the control group actually had a slightly greater reduction (60% vs. 50%). Kinesiology tape showed similarly underwhelming results, with no significant difference compared to doing nothing.
Binders may offer comfort and a sense of support in the early postpartum weeks, especially during activities like lifting or walking. But they don’t appear to speed healing beyond what your body does on its own, and they’re not a substitute for exercise-based rehabilitation.
When Surgery Becomes an Option
Most women with diastasis recti will never need surgery. It’s typically considered when conservative treatment has failed after a sustained effort, usually six months to a year of dedicated rehabilitation, or when a hernia develops alongside the separation. Hernias, where tissue or part of an organ pushes through a weak spot in the abdominal wall, are the most common reason diastasis repair moves from optional to medically recommended.
Surgical repair can be done through minimally invasive (laparoscopic) approaches or through open surgery. Laparoscopic repair is frequently used when a hernia needs to be fixed at the same time as the diastasis, and mesh reinforcement is almost always included when a hernia is present. Open surgery becomes the better option for women with excess skin, significant subcutaneous fat, a history of prior abdominoplasty, or obesity, since these factors make minimally invasive techniques riskier or less effective. Many women combine diastasis repair with an abdominoplasty (tummy tuck) to address both the muscle separation and loose skin in a single procedure.
A Realistic Timeline
The natural healing window is largest in the first six to eight weeks postpartum, when hormonal shifts and tissue remodeling are most active. By six months, about 45% of women still have a separation, and by 12 months, that figure settles around 33%. If you’re starting rehabilitation within the first few months, you’re working with biology on your side.
If you’re years past delivery, healing is still possible, but it tends to be slower and the focus shifts from closing the gap entirely to building functional strength across the midline. Many physical therapists consider a separation of one to two finger-widths with firm, responsive tissue underneath to be a successful outcome, even if it’s not a complete closure. What matters most is whether you can generate tension across your midline, transfer force through your trunk without pain, and do the activities you want to do without symptoms. The number on the tape measure is only part of the story.
