Balance Meets Fun – The New GIBBON Marble Core Trainer

Who says core training has to be sweaty but boring? With the new GIBBON Marble Core Trainer, your workout gets a playful upgrade – so much so that you might forget how hard you’re actually working.

The concept is as simple as it is brilliant: You combine your GIBOARD with a special attachment that lets you guide a marble through a track using only your balance skills. What sounds like child’s play challenges your core like few other tools – and keeps the fun factor high.

The Marble Core Trainer comes in two versions: for single-line setups and for duo setups. The latter adds extra lateral instability for even greater muscle activation. Both variants can be rotated 90 degrees, allowing you to train in all directions – whether side-to-side or forward-backward.

Here’s the magic: The workout doesn’t feel like a workout. While focusing on moving the marble, you’re making constant micro-adjustments to stay balanced, keeping your abs, back, and shoulders fully engaged. Planks, side planks, or dynamic movements – everything becomes an addictive challenge you’ll want to repeat.

Made in Switzerland from durable plastic, the Marble Core Trainer isn’t just compatible with the GIBOARD but also with slack racks, tricklines, and other slackline setups. Kids love it as a balance game, while adults value it as a smart and effective training tool.

Whether you want to spice up your core training, improve your balance, or simply have more fun while moving – the GIBBON Marble Core Trainer is your new go-to. Try it and experience how balance becomes your playground.
