Most people think "rotator cuff exercises" equal shoulder health. But without transverse rotational tension, you're actually setting your shoulder up to fail.
When the rotator cuff is trained in isolation, the shoulder becomes hyperflexible and unstable. Strength without integration isn't strength - it's compensation waiting to break.
Real shoulder power comes from an anchor, and that anchor is your trunk. If the core can't organize rotation and tension, the shoulder has nothing to stabilize against.
This is why all the passive hangs, banded mobility drills, and generic shoulder routines eventually lead people toward the same outcome: pain...and often surgery.
If you want durable shoulders, don't chase flexibility. Chase integration.
