Your neck is not weak.
It’s overloaded.
Cervical flexion isn’t just a posture issue — it’s a load-transfer problem.
As the head moves forward, the moment arm increases, and the effective load acting on the cervical spine rises disproportionately.
What feels like “just looking down” becomes compressive + shear stress across discs, muscles, and neural structures.
Small angles.
Big biomechanical cost.
Over time, sustained flexion drives:
• Compensatory neuromuscular overactivity
• Reduced regional blood flow
• Accelerated disc strain
• Lower fatigue resistance
• Poor motor efficiency
This is why neck pain often appears late, not early.
The system adapts first.
Pain is the last signal.
Key principle:
👉 Ergonomics is the first rep.
👉 Setup precedes force.
👉 Alignment precedes force.
👉 Stability precedes force.
Bring the device to eye level.
Not the head to the device.
Biomechanics isn’t about fear — it’s about load awareness.
