SlackBoards

For the best performance, we recommend 400 lb (181 kg) or less. Heavier users may find the line loses tension a little faster, which is normal and easy to fix by re-tensioning.

Just about anywhere! Use it on hard floors, carpet, outdoors, even at the beach. Since it’s made of wood, keep it out of the rain and don’t leave it in direct sunlight for long periods.

Yes. Kids build balance, coordination, and confidence while they play, and the low profile makes it easy to step off. It’s a fun, screen-free way to burn off energy, and the free GIBBON app includes programs for kids.

Yes! The low-to-the-ground design makes the SlackBoard great for beginners. Even though balancing on the line is challenging, because your foot is so close to the ground, it's easy to restart once you lose your balance.

Nope! Your SlackBoard arrives fully assembled, with the line already installed and tensioned. Just unbox it and step on.

Every board includes a tensioning dowel and instructions to re-tension anytime. The SlackBoard Plus and Pro also include everything you need to switch between one- and two-line setups.

Yes. In an 8-week UCLA study, people who trained on a SlackBoard improved their balance more than those who trained with conventional balance training tools. Read the full study on our Science page.

The SlackBoard is our original full-size, single-line balance board. It’s a great choice for anyone looking to challenge their balance, build strength and coordination, and progress their balance training.

The SlackBoard Plus is also full-size, but comes with two lines for a wider, more stable platform and can be easily converted to a single-line setup. It’s our most versatile option and is great for beginners, kids, workouts, recovery, and standing desks.

The SlackBoard Pro is built for gyms, sports performance facilities, and physical therapy clinics. Like the SlackBoard Plus, it switches between one and two lines, and it has larger neoprene pads on the bottom for added durability and grip.

The SlackBoard, SlackBoard Plus, and SlackBoard Pro all support up to 400 lb (181 kg).

No, the design is just the artwork. The model is what changes how the board works: the single-line SlackBoard, the two-line SlackBoard Plus, or the commercial SlackBoard Pro. Pick the model that fits how you’ll train, then choose the design you love.

No. The original single-line SlackBoard cannot be converted to a two-line setup. If you want the flexibility to switch between one and two lines, we recommend the SlackBoard Plus.

The SlackBoard is compact and easy to move or store.

• Dimensions: 42" L x 11" W x 5.5" H
• Weight: 7.5 lb (3.4 kg)

Absolutely! The SlackBoard sits low to the ground, so if you lose your balance, you just step off and try again.

Your SlackBoard arrives fully assembled with the line already installed, so you’re ready to get started. It also includes the Roll and Lock dowels, line clip, and tensioning rod.

The original SlackBoard has one line and is great if balance training is your main goal. Even a few minutes a day works your lower body and core. The SlackBoard Plus comes with two lines for a wider, more stable platform. Most first-timers find it easier, and it’s great for squats, standing desks, kids, and older adults. When you’re ready for more of a challenge, use the included clip to switch it to a single line. It’s like getting two boards in one.

No. The standard SlackBoard is designed as a single-line board and can't be converted. If you want to switch between one and two lines, choose the SlackBoard Plus or Pro.
