How to Safely Close Diastasis Recti: A 4‑Week Core Rehab Plan for New Moms

If you’re scrolling through Core Reboot right now, you’re probably feeling that little “gap” in your belly and wondering if it will ever close. Trust me, I’ve been there—late‑night feedings, endless diaper changes, and a belly that just won’t behave. The good news? With a gentle, step‑by‑step plan you can start seeing real change in just four weeks.

Why This Matters Right Now

Your core isn’t just about looking flat; it’s the support system for everything you do—lifting your baby, carrying groceries, even just getting out of bed. A wide diastasis (the split in the belly muscles) can lead to back pain, poor posture, and a feeling of “weakness” that makes daily life harder. Closing that gap safely means you’ll feel stronger, move easier, and protect your spine for years to come.

Week 1: Gentle Awareness

What to Do

Belly Breathing: Lie on your back with knees bent. Place one hand on your belly, the other on your chest. Breathe in through the nose, feeling the belly rise, then exhale slowly through the mouth, feeling the belly flatten. Do this for 3 minutes, twice a day.
Pelvic Tilts: Still on your back, gently press your lower back into the floor by tightening your belly and glutes. Hold for 5 seconds, release. Repeat 10‑12 times.
Supine Heel Slides: Slide one heel away from you while keeping the opposite foot flat. Keep your belly pulled in (imagine gently zipping up a jacket). Do 8‑10 slides each side.

Why It Works

These moves teach you how to engage the deep core muscles (the transverse abdominis) without bulging the belly outward. Think of it like learning to “talk” to the right muscles before you ask them to do heavy work.

Core Reboot Tip

I always start my day with belly breathing while the baby is still in the crib. It’s a quiet moment for me and a perfect way to remind my body what a strong core feels like.

Week 2: Adding Light Resistance

What to Do

Modified Bird‑Dog: On hands and knees, extend opposite arm and leg while keeping your belly pulled in. Hold 3 seconds, return. Do 8‑10 each side.
Standing Marches: Stand tall, engage your belly, and lift one knee to hip height. Alternate, keeping the core tight. 12‑15 reps each side.
Side‑Lying Hip Drops: Lie on your side with knees bent. Lift the top leg a few inches, then lower it slowly. Keep your belly pulled in. 10‑12 reps each side.

Why It Works

These exercises add a little challenge without putting pressure on the split. They also start training the muscles that help keep the pelvis stable—important for everyday tasks like picking up a stroller.

Core Reboot Reminder

If you feel any bulging or a “popping” sensation, stop that move and go back to the previous week’s routine. It’s better to be safe than to push too hard and set yourself back.

Week 3: Building Endurance

What to Do

Dead Bug (Modified): Lie on your back, arms up, knees bent at 90 degrees. Lower one foot toward the floor while keeping the opposite arm steady. Return and switch sides. Keep the belly flat. 10‑12 reps each side.
Wall Sit with Core Pull: Slide down a wall until thighs are parallel to the floor. While holding, gently pull your belly in. Hold for 20‑30 seconds, repeat 3 times.
Standing Side Bends: With feet hip‑width apart, place one hand on your hip and gently slide the other hand down the side of your thigh, pulling the belly in as you bend. 8‑10 reps each side.

Why It Works

Now the core muscles are getting a bit of a workout, but still under control. Endurance is key because you’ll need these muscles to stay active all day, not just during a short exercise session.

Core Reboot Insight

I love doing the dead bug while my little one naps on the couch. It’s a quick “core check‑in” that fits into any busy schedule.

Week 4: Strengthening the Whole Core

What to Do

Plank on Knees: Start on forearms and knees, pull the belly in, and lift the hips so your body forms a straight line from shoulders to knees. Hold 15‑20 seconds, repeat 3 times.
Standing Wood Chop (No Weight): Hold your hands together, pull them down to one hip, then lift them up across your body to the opposite shoulder, like chopping wood. Keep the core tight. 10‑12 reps each side.
Seated Russian Twists (No Weight): Sit with feet on the floor, lean back slightly, engage the belly, and rotate your torso left and right. 12‑15 twists each side.

Why It Works

These moves bring the whole core together—front, sides, and back. They also mimic real‑life movements, like turning to pick up a toy or reaching for a diaper bag.

Core Reboot Caution

If you feel any “ballooning” of the belly, drop back to the previous week’s level. The goal is to keep the split closed, not to push for a perfect six‑pack.

Keeping the Progress Going

Stay Consistent: A few minutes each day beats a long session once a week.
Listen to Your Body: Pain is a sign to stop; mild soreness is normal.
Combine with Good Nutrition: Protein and healthy fats help muscle repair.

I’ve seen countless new moms on Core Reboot go from feeling “floppy” to standing tall and confident. The key is patience and the right plan—exactly what this 4‑week guide gives you.

Give it a try, trust the process, and remember: every tiny pull‑in is a step toward a stronger you.
