How It Works
When you sit/stand tall and gently draw in your abdominal wall, Core-Set stays quiet.
When you slouch or let your abdomen relax outward, the mechanism provides a subtle vibration reminder.
Simply re-align your spine (neutral posture) and lightly re-engage your core; the vibration stops.
Best-Practice Posture Cues
Feet grounded, weight evenly distributed
Hips neutral; ribcage stacked over pelvis
Shoulders relaxed and slightly back (not forced)
Crown of head tall; chin level
Core gently engaged (as if zipping up a snug pair of jeans)
