Diastasis Recti Exercises: Heal Your Abdominal Separation Safely

You notice a bulge down the center of your stomach when you sit up. Or you can fit fingers into a gap between your ab muscles. Your core feels weak, your back hurts, and crunches make the bulge worse.

This is diastasis recti—a separation of the rectus abdominis muscles. It's most common after pregnancy but can happen to anyone. The good news: appropriate exercise can help close the gap and restore function.

What Is Diastasis Recti?

Your "six-pack" muscle (rectus abdominis) runs in two vertical strips down the front of your abdomen, connected by a band of tissue called the linea alba.

Diastasis recti occurs when this connective tissue stretches and thins, allowing the two muscle strips to separate.

Common Causes

Pregnancy: Most common cause. Growing uterus stretches abdominal wall. Rapid weight gain or loss: Stretches connective tissue Improper core training: Heavy lifting with poor technique Genetics: Some people have naturally thinner connective tissue Age: Tissue becomes less elastic over time

Symptoms

• Visible bulge or ridge down center of abdomen
• Gap you can feel between muscles
• Lower back pain
• Weak core
• Poor posture
• Pelvic floor dysfunction
• Digestive issues (in some cases)

Testing for Diastasis Recti

The Self-Test

1. Lie on your back, knees bent, feet flat
2. Place fingers horizontally just above your belly button
3. Slowly lift head and shoulders (like starting a crunch)
4. Feel for a gap between the muscle ridges
5. Measure width (number of fingers) and depth
6. Test at, above, and below belly button

Interpreting Results

Gap width:

• 1-2 fingers: May be normal, especially postpartum
• 2+ fingers: Likely diastasis requiring attention
• 3+ fingers: Significant separation

Depth matters too: A shallow gap may be more functional than a deep one.

When to see a professional: If you suspect significant diastasis, see a pelvic floor physical therapist for proper assessment.

The Exercise Approach

What to Avoid

Traditional ab exercises that increase intra-abdominal pressure can make diastasis worse:

• Crunches and sit-ups
• Planks (until foundational work is established)
• Leg raises
• Twisting movements under load
• Double leg lowering
• Any exercise that causes the belly to bulge or dome

Look for "doming": If your belly domes or tents during an exercise, stop. That's a sign the exercise is too advanced.

What Works

Exercises that:

• Activate the deep core (transverse abdominis)
• Coordinate breathing with core engagement
• Build strength without excessive pressure
• Progress gradually from foundational to functional

Foundation: Breathing and Core Activation

Diaphragmatic Breathing

Purpose: Learn to coordinate breath and core

How to do it:

1. Lie on back, knees bent
2. Place one hand on chest, one on belly
3. Breathe into belly (belly rises, chest stays relatively still)
4. Exhale fully, feeling belly fall
5. Practice 3-5 minutes daily

This is the foundation. Master it before progressing.

Connection Breath

Purpose: Connect breath to deep core activation

How to do it:

1. Lying position, knees bent
2. Inhale, let belly expand
3. Exhale, gently draw belly button toward spine
4. Imagine you're picking up a blueberry with your pelvic floor (gentle lift)
5. Hold for full exhale
6. Inhale, release
7. 10-15 breaths

Key: The engagement is gentle—30% effort, not max squeeze.

Transverse Abdominis Activation

Purpose: Wake up the deep core muscle that supports healing

How to do it:

1. Lying on back, knees bent
2. Find neutral spine (small curve in lower back)
3. Exhale and gently draw lower belly in toward spine
4. Imagine pulling hip bones together
5. Don't flatten lower back—keep neutral
6. Hold 5-10 seconds while breathing
7. Release, repeat 10 times

Progressive Exercise Sequence

Phase 1: Foundation (Weeks 1-4)

Do daily:

1. Connection breath: 10 breaths, 2-3 times daily

2. Heel slides:

• Lying on back, knees bent

• Inhale, return
• Keep pelvis stable—no rocking
• 10 each leg

3. Bent knee fallouts:

• Lying on back, knees bent
• Exhale, engage core
• Let one knee fall out to side
• Only go as far as you can keep pelvis stable
• Inhale, return
• 10 each side

4. Toe taps:

• Lying on back, legs at tabletop (90-90)
• Exhale, engage core
• Lower one foot to tap floor
• Inhale, return
• 10 each leg

Phase 2: Building (Weeks 4-8)

Continue Phase 1 exercises, add:

5. Dead bug (modified):

• Lying on back, arms toward ceiling, legs at tabletop
• Exhale, engage core
• Lower opposite arm and leg toward floor
• Only go as far as core stays engaged (no back arching)
• Inhale, return
• 10 each side

6. All-fours breathing:

• On hands and knees
• Let belly relax toward floor
• Exhale, draw belly up toward spine (without arching back)
• Hold 5 seconds
• Release, repeat 10 times

7. Bird dog (modified):

• On hands and knees, spine neutral
• Exhale, engage core
• Extend one arm forward
• Hold 5 seconds, return
• 10 each arm (add legs when stable)

Phase 3: Integration (Weeks 8-12+)

Continue previous exercises, add:

8. Side-lying clam:

• Lie on side, knees bent
• Exhale, engage core
• Lift top knee, keeping feet together
• 15 each side

9. Bridge with engagement:

• Lying on back, knees bent
• Exhale, engage core first
• Then lift hips
• Keep core engaged throughout
• 12 reps

10. Modified side plank:

• On forearm and knees
• Lift hips to create straight line from knees to shoulders
• Hold 15-30 seconds each side

11. Half kneeling holds:

• Kneel on one knee
• Maintain upright posture with core engaged
• Hold 30 seconds each side

Phase 4: Functional (Week 12+)

Gradually introduce:

12. Full plank (if no doming):

• Start with 10-15 second holds
• Monitor for doming—stop if it occurs

13. Pallof press:

• Standing with band at chest height

• 10 each side

14. Squats:

• Exhale and engage core on the way up

Important Principles

Always Engage Before Moving

Every exercise should start with an exhale and core engagement before movement begins.

Watch for Doming

If your belly domes or bulges during any exercise, that exercise is too advanced. Go back to an earlier progression.

Coordinate Breath

Exhale during the hard part of the exercise. This helps maintain intra-abdominal pressure control.

Progress Slowly

Moving too fast to harder exercises can worsen diastasis. Master each phase before progressing.

Consider Pelvic Floor

Diastasis often co-exists with pelvic floor dysfunction. If you have symptoms (leaking, pressure, pain), see a pelvic floor PT.

Lifestyle Modifications

Getting Up from Lying Down

Don't jack-knife up. Instead:

1. Roll to side
2. Use arm to push yourself up
3. Reduces pressure on separation

Lifting

• Exhale and engage core before lifting
• Avoid breath holding
• Keep loads close to body
• Don't lift too heavy during healing

Posture

Poor posture increases pressure on the linea alba:

• Stand tall, ribs stacked over pelvis
• Avoid rib flare (ribs jutting forward)
• Avoid excessive back arch

Constipation

Straining increases intra-abdominal pressure. Stay hydrated, eat fiber, don't strain.

When to Seek Professional Help

See a pelvic floor physical therapist if:

• Self-exercises aren't helping after 8-12 weeks
• Gap is significant (3+ fingers)
• You have pelvic floor symptoms
• You're unsure if you're doing exercises correctly
• Pain accompanies the diastasis
• You want faster, guided progress

Timeline Expectations

Week 1-4: Building awareness and foundational strength Week 4-8: Often see initial improvement in gap width and function Week 8-16: Continued progress with consistent work 3-6 months: Significant healing for many people

Factors affecting timeline:

• Severity of separation
• Consistency of exercise
• How long ago separation occurred
• Individual healing capacity
• Whether professional guidance is used

Surgery: When Is It Needed?

Most diastasis improves with exercise. Surgery (abdominoplasty or repair) is typically considered only when:

• Conservative treatment has failed after 6-12 months
• Functional problems persist
• Significant hernia is present
• Aesthetic concerns remain after functional recovery

Surgery is rarely the first option.

The Bottom Line

Diastasis recti is common and treatable. The key is:

1. Start with breathing and core activation
2. Progress gradually through exercise phases
3. Avoid exercises that cause doming
4. Exhale and engage before movement
5. Be consistent and patient

Your abs want to work together again. Give them the right exercises, proper progression, and time. Most diastasis improves significantly with dedicated effort.

Start with the foundation today. Your core is ready to reconnect.
