Intercostal Strain Exercises: Recovery for Rib Muscle Injury

An intercostal strain—injury to the muscles between your ribs—causes sharp pain with breathing, twisting, and coughing. Whether you strained it during a workout, from a violent cough, or playing sports, proper rehabilitation helps restore pain-free breathing and movement.

Understanding Intercostal Strains

The intercostal muscles are located between each rib. They expand and contract the rib cage during breathing and assist with trunk rotation and side bending.

Common causes:

• Twisting movements (golf, tennis, baseball)
• Direct trauma to ribs
• Violent coughing or sneezing
• Repetitive overhead reaching
• Heavy lifting with rotation
• Overuse in sports

Symptoms:

• Sharp pain between ribs
• Pain worse with breathing (especially deep breaths)
• Pain with twisting, bending, or reaching
• Pain with coughing, sneezing, or laughing
• Tenderness over the affected area
• Possible swelling or muscle spasm
• May feel like rib is broken

Recovery timeline:

• Mild strain: 2-3 weeks
• Moderate strain: 4-6 weeks
• Severe strain: 6-12 weeks

Rule out rib fracture: If trauma was involved or pain is severe, get an X-ray to rule out fracture.

Phase 1: Acute Management (Days 1-7)

Pain Control

Ice: 15-20 minutes every few hours (first 48-72 hours) Heat: After day 3 if it helps relax muscles Positioning: Find positions that reduce pain Breathing: Brace with pillow when coughing

Breathing Exercises

Maintain lung function while protecting the injury:

Diaphragmatic breathing:

1. Lie on back, hand on belly
2. Breathe into belly (not chest)
3. Slow, controlled breaths
4. Avoid deep breaths that cause sharp pain
5. 10-15 breaths, several times daily

Pursed lip breathing:

1. Inhale through nose for 2 counts
2. Exhale through pursed lips for 4 counts
3. Controlled, gentle breathing
4. 10-15 breaths

Why breathing matters: Shallow breathing from pain can lead to lung complications. Maintain as normal breathing as you can tolerate.

Supported Coughing

When you need to cough:

1. Hug a pillow firmly to chest
2. Brace core muscles
3. Cough while compressing pillow
4. Reduces strain on intercostals

Gentle Movement

Shoulder rolls:

1. Gently roll shoulders backward
2. Small movements
3. 10 repetitions
4. Several times daily

Gentle arm raises:

1. Raise arms to shoulder height (no higher initially)
2. Lower slowly
3. Pain-free range only
4. 10 repetitions

Phase 2: Mobility Restoration (Weeks 1-3)

Progressive Breathing

Deeper breaths:

1. Gradually increase breath depth
2. Inhale a bit more each day
3. Goal: Return to normal breathing depth
4. Monitor pain—some discomfort OK, sharp pain not

Costal breathing:

1. Place hands on sides of lower ribs
2. Breathe into your hands (expand ribs sideways)
3. Gentle, progressive
4. 10-15 breaths

Segmental breathing:

1. Place hand over injured area
2. Direct breath toward that hand
3. Encourages rib cage mobility
4. 10-15 breaths

Gentle Stretching

Side stretch (gentle):

1. Stand with feet shoulder-width
2. Raise arm on uninjured side overhead
3. Lean TOWARD injured side (stretches uninjured side)
4. Progress to leaning away (stretching injured side)
5. Hold 15-20 seconds
6. Very gentle initially

Seated rotation (gentle):

1. Sit in chair, feet flat
2. Cross arms over chest
3. Rotate toward uninjured side first
4. Then toward injured side (carefully)
5. Stay within comfort
6. 5-10 each direction

Thoracic extension:

1. Sit in chair
2. Hands behind head
3. Gently arch upper back over chair back
4. Small movement initially
5. 5-10 repetitions

Phase 3: Strengthening (Weeks 3-6)

Core Stabilization

Diaphragmatic breathing with core engagement:

1. Lie on back, knees bent
2. Breathe into belly
3. As you exhale, gently engage core
4. Hold through next breath cycle
5. 10-15 breaths

Dead bugs (modified):

1. Lie on back, arms up
2. Keep feet on floor initially
3. Lower one arm overhead
4. Control breathing throughout
5. 10 each side
6. Progress to legs involved

Bird dogs:

1. On hands and knees
2. Extend opposite arm and leg
3. Maintain breathing
4. 10-12 each side

Trunk Strengthening

Seated rotation with resistance:

1. Sit with band attached to side
2. Rotate away from attachment
3. Control return
4. 10-12 repetitions each side
5. Light resistance initially

Side plank (modified):

1. On elbow and knees
2. Lift hips off ground
3. Start on uninjured side
4. Progress to injured side
5. Hold 15-30 seconds

Pallof press:

1. Band at chest height
2. Press forward, resist rotation
3. Involves intercostals for stability
4. 10-12 repetitions each side

Breathing Under Load

Breathing during exercise:

1. Practice maintaining normal breathing
2. During planks, bird dogs, etc.
3. Don't hold breath
4. Builds intercostal endurance

Phase 4: Return to Activity (Weeks 6+)

Progressive Loading

Full trunk exercises:

• Cable rotations
• Wood chops
• Rotational throws
• Progressive resistance

Sport-specific:

• Throwing progression
• Golf swing progression
• Tennis stroke progression
• Start at 50% intensity

Full Breathing

High-intensity breathing:

1. Interval training
2. Swimming
3. Activities requiring full breath capacity
4. Progress intensity gradually

Stretching Routine

Daily Stretches

Cat-cow:

1. On hands and knees
2. Round and arch spine
3. 10-15 repetitions

Thread the needle:

1. On hands and knees
2. Reach one arm under and through
3. Feel stretch through ribs/back
4. Hold 20-30 seconds each side

Side-lying stretch:

2. Reach top arm overhead
3. Feel stretch along side
4. Hold 30 seconds

Doorway chest stretch:

1. Arm on door frame
2. Turn body away
3. Opens rib cage
4. Hold 30 seconds each side

Sample Rehabilitation Program

• Diaphragmatic breathing: 15 breaths
• Shoulder rolls: 10 reps
• Supported coughing as needed
• Ice or heat as helpful

Phase 2 (Weeks 1-3)

Daily:

• Progressive breathing exercises
• Gentle stretches: 20 seconds each
• Gentle rotation ROM

3x weekly:

• Dead bugs (modified): 2 × 10

Phase 3-4 (Weeks 3-6+)

3x weekly:

• Core exercises: 2-3 sets each
• Trunk strengthening: Progressive
• Return to sport activities: Gradual

Daily:

• Full stretching routine
• Normal breathing activities

When to Seek Medical Attention

See a doctor if:

• Severe pain not improving
• Difficulty breathing
• Suspected rib fracture (trauma)
• Pain with fever
• Symptoms worsening
• No improvement after 2-3 weeks

Preventing Re-Injury

1. Maintain core strength - Supports rib cage
2. Thoracic mobility - Regular rotation exercises
3. Proper warm-up - Before rotational sports
4. Proper technique - Golf, tennis, throwing
5. Address coughing - Treat underlying causes
6. Gradual progression - In training intensity

The Bottom Line

Intercostal strain recovery centers on breathing:

1. Maintain breathing - Don't breathe too shallowly
2. Progress gradually - From gentle to normal depth
3. Restore rotation - Essential for most activities
4. Strengthen the core - Supports the rib cage
5. Return to activity gradually - Rotational sports last

Intercostal strains can be surprisingly painful and slow to heal. Be patient—the ribs move with every breath you take, so complete rest isn't possible. Focus on controlled, progressive loading and your intercostals will heal fully.
