Understanding PRI: The Postural Restoration Institute Approach to Movement and Health
Discover how PRI (Postural Restoration Institute) uses breathing, asymmetrical patterns, and targeted exercises to restore balance, eliminate pain, and improve movement quality.

If you've ever experienced chronic pain, movement restrictions, or postural imbalances that traditional approaches couldn't resolve, you may have heard of PRI—Postural Restoration Institute. This revolutionary approach to movement and rehabilitation has helped thousands of people restore function and eliminate pain by addressing the root causes of dysfunction rather than just treating symptoms.
What is PRI?
The Postural Restoration Institute® (PRI) is a continuing education institute established in 2000 that focuses on understanding and addressing the body's natural asymmetrical patterns and postural adaptations. Unlike conventional approaches that view the body as symmetrical, PRI recognizes that asymmetry is normal and necessary for optimal function.
However, when this natural asymmetry becomes exaggerated or when compensatory patterns develop, pain and dysfunction emerge. PRI practitioners use a comprehensive approach that integrates neurological, respiratory, and muscular systems to identify and correct these imbalances.
Core Principles of PRI
1. Natural Asymmetry
The human body is inherently asymmetrical. We have:
- A liver on the right side
- A heart positioned on the left
- Different diaphragm attachment points
- Asymmetric muscle attachments
This asymmetry is essential for function—think of how you naturally favor one hand, one leg for kicking, or one eye for aiming. PRI recognizes this and works with it rather than against it.
2. The Role of Breathing
PRI places enormous emphasis on proper breathing mechanics. The diaphragm isn't just for breathing—it's a critical postural muscle that influences:
- Pelvic positioning
- Ribcage mobility
- Spinal alignment
- Core stability
Dysfunctional breathing patterns can create a cascade of compensations throughout the body. PRI uses specific breathing exercises to reset these patterns and restore proper neuromuscular function.
3. Left Anterior Interior Chain (AIC) Pattern
PRI identifies a common postural pattern called the Left AIC Pattern, where the body adapts to left-sided dominance, often resulting in:
- Right hip internal rotation
- Left hip external rotation
- Anterior pelvic tilt
- Forward head posture
- Compensatory breathing patterns
Understanding and addressing these patterns is central to PRI methodology.
4. Integration of Systems
PRI doesn't view the body in isolation. Instead, it recognizes how:
- Neurological patterns drive muscular behavior
- Respiratory function influences posture
- Muscular imbalances affect movement quality
- Positional relationships determine function
All systems must work together harmoniously for optimal movement.
Common PRI Exercises in Peak Health
Several exercises in Peak Health are based on PRI principles:
90/90 Hip Lift
Performed with feet against a wall and a ball between the knees, this exercise promotes proper pelvic positioning, hamstring activation, and diaphragmatic breathing—core tenets of PRI.
90-90 Diaphragmatic Breathing
A fundamental PRI breathing exercise that teaches proper diaphragm activation and prolonged exhalation, helping reset neuromuscular patterns.
90/90 Hip Rotations
Addresses rotational imbalances in the hip, working with the body's natural asymmetrical patterns to restore optimal range of motion.
These exercises aren't random movements—they're carefully designed to:
- Reset dysfunctional patterns
- Restore proper breathing mechanics
- Activate underactive muscles
- Inhibit overactive muscles
- Improve postural alignment
Who Benefits from PRI?
PRI can help individuals experiencing:
- Chronic pain that hasn't responded to traditional treatment
- Recurring injuries
- Postural imbalances
- Breathing dysfunction
- Movement restrictions
- Sports performance plateaus
- Asymmetries affecting daily life or athletic performance
Common Conditions Addressed
- Lower back pain
- Neck and shoulder pain
- Hip impingement
- Knee pain
- Breathing difficulties
- Postural dysfunction
- Athletic performance issues
What Makes PRI Different?
1. Root Cause Focus
Instead of just treating symptoms (tight muscles, sore joints), PRI addresses the underlying patterns that create these symptoms in the first place.
2. Systematic Assessment
PRI practitioners use specific tests to identify:
- Postural patterns
- Breathing dysfunction
- Neuromuscular imbalances
- Movement restrictions
This systematic approach ensures treatment targets the actual problem, not just the symptoms.
3. Exercise Prescription Based on Pattern
Not everyone gets the same exercises. PRI practitioners prescribe specific exercises based on the individual's unique pattern of dysfunction, making the approach highly personalized.
4. Integration Over Isolation
PRI exercises rarely work in isolation. They're designed to integrate multiple systems—breathing, posture, movement—for comprehensive restoration.
Getting Started with PRI
Working with a PRI-Certified Practitioner
For complex issues or chronic pain, working with a PRI-certified physical therapist or trainer is recommended. They can:
- Assess your specific pattern
- Develop a personalized program
- Provide hands-on treatment
- Guide your exercise progression

Self-Directed PRI Exercises
Many foundational PRI exercises can be practiced at home. The exercises available in Peak Health provide a solid introduction to PRI principles:
- Start with breathing exercises (90-90 Diaphragmatic Breathing)
- Progress to positional exercises (90/90 Hip Lift)
- Add mobility work (90/90 Hip Rotations)
- Practice consistently for best results
Key Principles for Practice
- Quality over quantity: Move slowly and intentionally
- Focus on breathing: Proper breathing is non-negotiable in PRI
- Position matters: Exact positioning is crucial for effectiveness
- Patience is essential: Neural patterns take time to change
- Consistency wins: Regular practice creates lasting change
The Science Behind PRI
PRI is grounded in:
- Neuroplasticity (the brain's ability to reorganize)
- Biomechanics (how forces move through the body)
- Respiratory physiology (breathing mechanics)
- Motor learning (how movement patterns develop and change)
- Postural science (understanding natural asymmetries)
This scientific foundation makes PRI more than just exercises—it's a comprehensive system for understanding and restoring human movement.
Common Misconceptions
"PRI is just breathing"
While breathing is central, PRI integrates breathing with movement, position, and neuromuscular function for comprehensive restoration.
"PRI is only for people with pain"
PRI can enhance movement quality, prevent injury, and improve performance even for those without pain.
"You need to see a PRI practitioner"
While professional guidance is valuable, many foundational exercises can be safely practiced at home, especially as preventive measures or for movement quality improvements.
"PRI exercises are easy"
PRI exercises may look simple, but they require precision, focus, and proper execution. They're deceptively challenging.
Integration with Your Training
PRI doesn't replace your training—it enhances it. Use PRI exercises to:
- Warm-up: Prepare your body for movement
- Cool-down: Reset patterns after training
- Recovery: Active recovery between training sessions
- Rehabilitation: Address imbalances and restrictions
- Prevention: Maintain optimal movement quality
Conclusion
PRI offers a unique perspective on human movement that recognizes natural asymmetry, emphasizes proper breathing, and integrates multiple body systems for comprehensive restoration. Whether you're dealing with chronic pain, movement restrictions, or simply want to move better, PRI principles can enhance your movement quality and overall health.
The exercises available in Peak Health provide an excellent entry point into PRI methodology. Start with the breathing exercises, progress through positional work, and experience how addressing root causes rather than symptoms can transform your movement.
Remember: optimal movement isn't about perfect symmetry—it's about balanced asymmetry and integrated function across all your body's systems.
