Pectus Excavatum Exercises: A Complete Guide to Posture & Strength Training
Important Medical Disclaimer
This guide provides general exercise information for educational purposes only. Pectus excavatum severity varies significantly between individuals. Always consult your GP or specialist before starting any exercise programme, particularly if you experience chest pain, breathing difficulties, or have undergone corrective surgery. Exercise cannot cure pectus excavatum but may help improve associated posture and muscle strength.
As a personal trainer with over 15 years of experience working with clients across Hale Barns, Sale, and Altrincham, I've helped many individuals with pectus excavatum develop safe, effective exercise programmes. While exercise won't correct the structural deformity, targeted training can significantly improve posture, strengthen supporting muscles, and enhance quality of life.
Pectus excavatum, commonly known as "sunken chest" or "funnel chest," affects approximately 1 in 300-400 people. While the condition is primarily structural, many individuals find that targeted exercise helps reduce associated symptoms such as poor posture, muscle imbalances, and reduced confidence. This comprehensive guide covers the most effective exercises and training strategies.
Understanding Pectus Excavatum and Exercise
What Exercise Can (and Cannot) Do
Exercise CAN Help With:
- • Improving overall posture
- • Strengthening chest and back muscles
- • Reducing forward shoulder rounding
- • Increasing lung capacity through breathing exercises
- • Building core stability
- • Boosting confidence and body image
- • Minimising the visual appearance of the condition
Exercise Cannot:
- • Correct the underlying bone structure
- • Replace medical treatment when severe
- • Fix the condition without other interventions
- • Substitute for professional medical advice
Essential Chest Strengthening Exercises
Building muscle around the chest can help create a fuller appearance and improve posture. Focus on exercises that target the pectoralis major and minor, with emphasis on proper form.
1. Incline Dumbbell Press
Why it works: The incline angle targets the upper chest, which is often underdeveloped in individuals with pectus excavatum, helping to create a more balanced chest appearance.
How to perform:
- Set bench to 30-45 degree incline
- Hold dumbbells at shoulder level, palms facing forward
- Press upward, bringing dumbbells together at the top
- Lower slowly with control
- Perform 3 sets of 10-12 repetitions
Tip: Focus on squeezing the chest at the top of the movement and use a weight that allows controlled form.
2. Dumbbell Flyes
Why it works: Flyes stretch and strengthen the chest muscles, particularly the outer portions, helping to create width and definition.
How to perform:
- Lie flat on a bench with dumbbells above chest
- With a slight bend in elbows, lower arms out to sides
- Stop when you feel a stretch in the chest
- Squeeze chest muscles to bring dumbbells back together
- Perform 3 sets of 12-15 repetitions
Tip: Use lighter weight than pressing exercises and focus on the stretch and contraction.
3. Push-Up Variations
Why it works: Push-ups are versatile, can be done anywhere, and effectively target the entire chest while engaging core stabilisers.
Progressive variations:
- Wall push-ups: Beginner-friendly starting point
- Incline push-ups: Hands on raised surface
- Standard push-ups: Classic chest builder
- Wide-grip push-ups: Greater chest emphasis
- Decline push-ups: Feet elevated for upper chest focus
Tip: Keep your core engaged and body in a straight line throughout.
4. Cable Crossovers
Why it works: Cables provide constant tension throughout the movement, excellent for developing chest definition and mind-muscle connection.
How to perform:
- Set cables at shoulder height or slightly above
- Step forward with one foot for stability
- Bring handles together in front of chest in a hugging motion
- Squeeze at the bottom, then slowly return
- Perform 3 sets of 12-15 repetitions
Posture Correction Exercises
Poor posture often accompanies pectus excavatum, with rounded shoulders and forward head position being common. These exercises help counteract these tendencies.
1. Face Pulls
Target: Rear deltoids, upper back, rotator cuff
How to perform: Using a cable machine or resistance band at face height, pull towards your face while externally rotating shoulders. Squeeze shoulder blades together at the end position.
Sets/Reps: 3 sets of 15-20 repetitions
2. Prone Y-T-W Raises
Target: Lower trapezius, rhomboids, posterior deltoids
How to perform: Lying face down on a bench or floor, raise arms to form the letters Y, T, and W. Hold each position for 2-3 seconds.
Sets/Reps: 2 sets of 8-10 each position
3. Wall Angels
Target: Thoracic mobility, shoulder positioning
How to perform: Stand with back, head, and arms flat against a wall. Slowly slide arms up and down while maintaining contact with the wall.
Sets/Reps: 2 sets of 10-15 repetitions
4. Thoracic Extension on Foam Roller
Target: Upper back mobility
How to perform: Place foam roller horizontally under upper back. Support head with hands and gently extend backwards over the roller. Move roller to different positions along the upper back.
Duration: 2-3 minutes daily
Breathing Exercises for Lung Capacity
Some individuals with pectus excavatum experience reduced lung capacity. These breathing exercises can help maximise lung function and improve respiratory efficiency.
1. Diaphragmatic Breathing
How to perform:
- Lie on your back with knees bent
- Place one hand on chest, one on abdomen
- Breathe in slowly through your nose, focusing on expanding your belly (the hand on your abdomen should rise)
- Exhale slowly through pursed lips
- The hand on your chest should remain relatively still
Duration: 5-10 minutes, 2-3 times daily
2. Rib Expansion Breathing
How to perform:
- Sit or stand with hands placed on sides of ribcage
- Inhale deeply, focusing on pushing ribs outward into hands
- Hold for 2-3 seconds at full expansion
- Exhale slowly and completely
Duration: 10-15 breaths, 2-3 times daily
3. Vacuum Breathing Exercise
How to perform:
- Exhale all air from lungs
- Expand chest cavity without taking in air (as if trying to breathe in, but keeping airways closed)
- Hold for 3-5 seconds
- Release and breathe normally
Note: This exercise should be performed carefully and stopped if you feel dizzy or uncomfortable.
Core Strengthening for Support
A strong core provides foundational support for better posture and reduces compensatory movement patterns.
Dead Bug
Lie on back, arms extended upward, knees at 90 degrees. Lower opposite arm and leg while maintaining lower back contact with floor. 3 sets of 10 each side.
Bird Dog
On hands and knees, extend opposite arm and leg while keeping spine neutral. Hold for 2-3 seconds. 3 sets of 10 each side.
Plank
Hold push-up position on forearms, maintaining straight line from head to heels. Focus on breathing steadily. Work up to 60 seconds.
Side Plank
Support body on one forearm and side of foot. Keep body in straight line. Hold 20-30 seconds each side. 2-3 sets.

Important Considerations
When to Seek Medical Advice
Consult a healthcare professional if you experience chest pain during exercise, shortness of breath beyond normal exertion, palpitations, dizziness, or if your symptoms worsen. Those who have had or are considering surgical correction should work closely with their medical team regarding exercise.
Progress Gradually
Start with lighter weights and fewer sets, focusing on perfect form before increasing intensity. Progress should be slow and steady, typically increasing weights by no more than 5-10% per week when form is consistently good.
Consistency is Key
Results from exercise take time, often 8-12 weeks before noticeable improvements in posture and muscle development. Stay consistent with your programme and track your progress through photos or measurements.
Working with a Personal Trainer

- Customise exercises based on your specific presentation and severity
- Monitor form to ensure safe, effective technique
- Progress your programme appropriately as you improve
- Provide motivation and accountability
- Coordinate with medical professionals if needed
