Approximately 60% of women experience diastasis recti — a separation of the abdominal muscles — six weeks postpartum, and for about 32%, the condition persists at the 12-month mark. If you are frustrated by a lingering “mommy pooch,” experiencing lower back pain, or dealing with unexpected pelvic floor issues, your abdominal connective tissue may still be struggling to recover from the incredible strain of pregnancy.
The good news is that diastasis recti is highly treatable, and it is rarely too late to start healing. However, traditional fitness advice often does more harm than good. Returning to your pre-pregnancy core routine of crunches, planks, and sit-ups can actually widen the gap and permanently damage the delicate tissue connecting your abdominal wall. Healing requires a fundamental shift: you must stop focusing on the “six-pack” muscles and start rebuilding the deep, foundational transverse abdominis.
Key Takeaways
- Diastasis recti is not a tear in your muscles, but a stretching and thinning of the linea alba, the connective tissue running down your midline.
- Avoid sit-ups, crunches, and heavy lifting postpartum. These movements increase intra-abdominal pressure and make the separation worse.
- Healing is defined by functional tension (the ability of the tissue to bear weight), not just physically closing the gap to zero.
What is Diastasis Recti and Why Does It Happen?
To accommodate a growing baby, your abdominal wall has to expand. Your rectus abdominis (the “six-pack” muscles) are joined down the center of your stomach by a band of connective tissue called the linea alba. Under the pressure of a growing uterus and the influence of pregnancy hormones like relaxin, the linea alba stretches, thins, and widens, causing the two sides of the abdominal muscle to separate.
After delivery, the muscles do not simply snap back together like a rubber band. Because the linea alba is connective tissue (similar to a ligament) rather than muscle, it requires time, proper alignment, and specific rehabilitative tension to regain its density and strength. When this tissue remains overly stretched and weak, the internal organs press forward against the abdominal wall, creating the characteristic bulging appearance often referred to as a “mommy pooch.”
How to Check Yourself for Diastasis Recti at Home
You can easily perform a self-assessment to check the width and depth of your abdominal separation. Do not perform this check until you are at least 3–4 weeks postpartum to allow for initial natural healing.
- Lie flat on your back with your knees bent and feet flat on the floor.
- Place one hand behind your head to support your neck.
- Place the fingers of your other hand flat across your midline, just above your belly button.
- Gently lift your head and shoulders an inch off the floor (as if doing a mini-crunch).
- Feel for a gap. Move your fingers above, over, and below the belly button. Assess how many fingers fit into the gap (width) and how far your fingers sink into your belly (depth).
A gap of 1–2 fingers is generally considered normal postpartum. A gap of 2.5 fingers or more, especially if the tissue feels very soft or squishy (lacking tension), indicates diastasis recti.
The Postpartum Healing Timeline
Rehabilitating connective tissue is a marathon, not a sprint. Setting realistic expectations will keep you from getting discouraged.
What to Avoid: The “Do Not Do” List
When you have diastasis recti, managing intra-abdominal pressure is the most critical rule of recovery. If you perform an exercise that pushes pressure outward against a weak abdominal wall, the separation will worsen. Avoid the following until a physical therapist clears you:
- Traditional Ab Exercises: Sit-ups, crunches, bicycle crunches, and Russian twists.
- Front-Loaded Planks: Full push-ups and standard planks place too much gravity and pressure on the healing linea alba.
- Arching the Back: Yoga poses like upward-facing dog or full wheel stretch the abdominal wall excessively.
- Improper Sitting Up: Never jackknife straight up out of bed. Roll to your side and use your arms to push yourself up.
- Heavy Lifting: Avoid lifting anything heavier than your baby while holding your breath (valsalva maneuver), as this spikes internal pressure.
⚠️ The Danger of “Coning”
Always watch your stomach while exercising. If you see a ridge, dome, or cone shape bulging down the center of your midline, stop immediately. Coning means the exercise is too difficult for your current core strength, and the internal pressure is pushing directly against your vulnerable connective tissue.
5 Safe Exercises to Rebuild Your Core
The secret to fixing diastasis recti is targeting the transverse abdominis (TVA) — the deep corset-like muscle that wraps around your torso. Strengthening the TVA pulls the rectus abdominis back toward the midline and restores tension to the linea alba.
1. 360-Degree Diaphragmatic Breathing
This is the foundation of all core rehab. Sit or lie down. Inhale deeply so that your ribcage expands outward in all directions (not just your belly pushing out). As you exhale, gently draw your belly button in and up toward your spine, as if you are zipping up a tight pair of high-waisted jeans. Do not suck in forcefully. Repeat 10 times daily.
2. Pelvic Tilts
Lie on your back with knees bent and feet flat. Inhale to let your belly relax. As you exhale, engage your deep core and gently tilt your pelvis upward so your lower back presses completely flat against the floor. Hold for 3 seconds, then release. Repeat 10–15 times.
3. Heel Slides
Start in the same position as the pelvic tilt. Engage your core so your back is flat against the floor. Slowly slide your right heel out until the leg is straight, then slowly slide it back. If your lower back arches or pops off the floor, you have lost core engagement. Switch legs. Do 10 reps per side.
4. Glute Bridges
Lie on your back with knees bent. Engage your core (zip up the deep abdominals) and squeeze your glutes to lift your hips off the floor until your body forms a straight line from knees to shoulders. Do not over-arch your back at the top. Lower down slowly. Repeat 12 times.
5. Bird-Dog
Get on your hands and knees (tabletop position). Ensure your back is flat. Exhale and engage your core to prevent your belly from sagging toward the floor. Slowly extend your right arm forward and your left leg backward. Hold for 2 seconds, then return to the start. Watch your stomach for coning. Do 8 reps per side.
💡 Pro Tip
Consistency beats intensity. Ten minutes of focused, slow, breath-matched core work done every single day will heal diastasis recti significantly faster than an hour-long intense workout done twice a week.
When to See a Pelvic Floor Physical Therapist
While home exercises are highly effective, the gold standard of care is working with a specialized professional. You should absolutely seek out a Pelvic Floor Physical Therapist (PFPT) if:
- Your gap is larger than 3 fingers wide or feels incredibly deep.
- You experience leaking urine when you sneeze, cough, or jump (incontinence).
- You have chronic lower back pain or pelvic pain that does not improve.
- You feel a heavy, dragging sensation in your pelvis (a potential sign of pelvic organ prolapse).
- You have been doing rehab exercises for 3 months with no improvement in tension or appearance.
Frequently Asked Questions
Can you fix diastasis recti years after having a baby?
Yes, absolutely. Connective tissue and muscle can be strengthened and rehabilitated at any point. While natural healing peaks in the first few months postpartum, targeted transverse abdominis exercises can successfully close the gap and restore tension even 5 or 10 years after giving birth.
Does a belly band help heal diastasis recti?
A postpartum belly band or wrap can provide comfortable external support for your lower back and posture during the first few weeks after birth. However, it will not heal diastasis recti on its own and should not be used as a substitute for strengthening your internal core muscles.
Is it possible to close the gap completely?
For some women, the gap closes completely. For others, a functional 1–2 finger gap may remain permanently. The goal of rehabilitation is “functional tension”—meaning the connective tissue is strong enough to bear weight and support your organs without bulging, regardless of the gap’s physical width.
Does running make diastasis recti worse?
Running is a high-impact exercise that places significant downward pressure on the pelvic floor and forward pressure on the abdominal wall. If your core is not healed enough to manage this pressure, running can exacerbate diastasis recti. It is recommended to stick to low-impact cardio until core tension is restored.
Can diastasis recti cause lower back pain?
Yes. Your abdominal muscles and back muscles work together to stabilize your spine. When the front of your core is severely weakened by abdominal separation, your lower back muscles have to overcompensate to keep you upright, leading to chronic tightness and pain.
Healing diastasis recti is a journey of reconnecting with a body that has accomplished something extraordinary. It requires unlearning the “no pain, no gain” fitness mentality and embracing slow, mindful, breath-focused movement. Give your connective tissue the time and respect it deserves. By avoiding movements that spike intra-abdominal pressure and focusing entirely on your deep core, you will not only reduce the postpartum pooch, but you will build a stronger, more functional foundation than you had before pregnancy.
