Gibbon Balance Board Accessory Core Marble Trainer - Double Line

The Core Marble Trainer is much more than just an accessory - it's a real asset for your GIBOARD. Imagine a marble circuit controlled not by your hands, but by your whole body. Every subtle movement of your feet, hips, or torso sets the marble in motion - or stops it dead. Balance, concentration, and body tension come together in a fun and completely new training experience. Whether it's for a quick challenge or a focused core workout, the Core Marble Trainer transforms your GIBOARD into a dynamic training surface with real benefits. You'll feel it right away - your body is engaged. And at the same time, it's incredibly fun to guide the marble through the course. Perfect for a full-body workout and strengthening deep muscles.
