Passive hanging gets praised as a cure all, but it only trains one aspect of spinal adaptability: straight line decompression.
The issue is that it overstretches the shoulder ligaments and completely misses the dynamic forces your spine deals with in real life.
Your spine is not built for just one direction of movement. It needs rotation, lateral tension, and compressive forces to stay strong and adaptable. That does not come from hanging limp.
It comes from active, biomechanically sound movement.
When you train the patterns humans evolved for such as standing, walking, running, and throwing, your spine becomes resilient without hypermobilizing your joints or creating instability.
Real adaptability comes from integration, not passive stretching.
