The Missing Link: Why Your Core Might Not Be Working (Even If You Think It Is)

As a fitness professional, I've observed a pattern in clients with recurring injuries and persistent pain. Here's what I've discovered about the often-overlooked connection between your ribcage and pelvis—and why it might be the key to pain-free movement.
The Two-Piece Problem
Have you ever noticed someone's torso moving like it's in two separate pieces during a simple exercise? Perhaps their ribcage pops forward when they try to bridge their hips, or their lower back excessively arches when they reach overhead?
What you're seeing isn't just poor form—it's a fundamental disconnection in how the body is designed to function.
Beyond the Six-Pack
When most people think about core strength, they imagine visible abs or the ability to hold a plank. But true core function is something more foundational: the ability of your ribcage and pelvis to work together as a coordinated unit.
This connection forms the foundation of all movement. When it's working properly, force transfers efficiently through your body. When it's not, a cascade of compensations occurs, often leading to:
Recurring back pain
Tight, overactive quads
Weak, inactive glutes
Hamstring injuries
Limited rotation
Poor athletic performance
The Modern Disconnect
So why is this disconnection so common? Our modern lifestyle creates the perfect storm:
Office jobs place us in seated positions for hours, where hip flexors tighten, glutes deactivate, and our ribcage-pelvis relationship becomes distorted.
Screen time encourages forward head posture, which affects the entire spine down to the pelvis.
Stress patterns alter our breathing mechanics, often leading to chest breathing and rib flaring.
Lack of movement variety means we never challenge our bodies through diverse positions that would naturally maintain this connection.
The Warning Signs
How do you know if you're experiencing this disconnection? Watch for these signs:
Your lower back feels tight or achy, especially after exercise
You struggle to activate your glutes properly
You experience calf tightness that never seems to resolve
Your body visibly shakes during simple movements
Running or impact activities hurt your back
You have recurring hip, knee, or ankle issues
You can visibly see your ribs "pop forward" when moving
Beyond Stretching and Strengthening
The solution isn't just stretching tight muscles or strengthening weak ones. Those approaches often fall short because they don't address the fundamental movement pattern.
Instead, rebuilding the ribcage-pelvis connection requires a progressive approach:
Awareness: Learning to feel and identify proper positioning
Control: Developing the ability to maintain connection during basic movements
Challenge: Testing connection during more complex or dynamic activities
Integration: Making connected movement your default in daily life
Natural Movement as Medicine
Interestingly, activities like hill hiking can be particularly therapeutic for this disconnection. The varied terrain and inclines naturally facilitate proper muscle engagement and movement sequencing that many of us have lost.
When navigating hills:
Glutes must engage properly
Core must integrate with lower body
Movement patterns become more varied and less predictable
This may explain why many people find that hiking in hilly terrain alleviates back pain and makes them feel stronger in everyday life—it's restoring natural movement patterns that our bodies are designed for.
The Simply Human Approach
At Simply Human, we believe in returning to fundamental movement principles. Our approach to rebuilding the ribcage-pelvis connection focuses on:
Establishing proper breathing mechanics
Developing core awareness and control
Building the mind-body connection
Progressively challenging stability
Integrating proper patterns into daily movement
The Path Forward
Whether you're dealing with persistent pain or simply want to move better, understanding and addressing this core connection can be transformative.
You can join our "Pain-Free Movement Project" a 30-day challenge designed to restore this fundamental connection and help you rediscover how your body is naturally designed to move.
Remember: true core strength isn't about how many sit-ups you can do. It's about how well your body functions as the integrated system it was designed to be.
