Yes. And “BOSU® ball” isn’t a nickname, it’s the original name.

Back when it was the only product, that’s what it was called. Then BOSU® grew into a brand spanning a whole range of equipment, and the product needed a name of its own.

Balance Trainer is that name, and it’s the more accurate one: BOSU® stands for BOth Sides Utilized. Dome side up, platform side up — two surfaces, trained differently.

So if you came looking for a BOSU® ball, you’ve found it. The name is BOSU® Balance Trainer now.

You may return your BOSU® purchase within 30 days from receipt for full refund. If the return falls outside of this period, or the item is worn, damaged or not in its original packaging, BOSU® cannot accept the returned items and cannot give a refund.

To avoid harming the valve and surrounding area, we suggest using a spoon to remove the plug from both the Balance Trainer and Ballast Ball. A second option is to purchase the official BOSU® Plug Puller is designed to remove Balance Trainer plugs (right side of tool) and Ballast® Ball plugs (left side of tool) without causing damage.

Inflate the Balance Trainer until the dome is 8.5” high (do not exceed 10” high). The dome should “give” a little when standing, sitting or kneeling on it. Click here to watch a video on proper inflation. 

Your Balance Trainer may need time to settle once inflated. There can be a “hissing” air noise that is a normal occurrence from the dome settling on the base platform. As long as your unit is retaining air there is no need to worry. 

You can try using a Vinyl patch from an air mattress, pool liner, or waterbed that can be picked up at your local hardware store. We also recommend trying a product found online called AirStop . It comes in a tube like toothpaste. Several customers have had success with this product. AirStop is made for patching Vinyl footballs, basketballs, soccer balls, etc.

Two reasons this issue may occur: 1) over-inflation, or 2) exposure to sunlight and/or heat sources. The dome should only be inflated between 8.5” to 10” high. The owner’s manual covers this information on pg. 5, “Care & Storage” and pg. 7, “Getting Started.” To fix the Balance Trainer, remove the plug (use a spoon to help with this,) deflate the dome completely and remove bolts from each side of the clamp, click here for instructions. Then, work the bladder-ribbed edge to fit back onto the base, fit the clamp back on, tighten and re-inflate the unit. This should solve the issue. For repair instructions, please contact Customer Service.

Store your Balance Trainer out of direct sunlight. Store platform side down, dome side up. For multiple Balance Trainers avoided dome to platform contact, they should be stacked either dome to dome or platform to platform.

The oil is caused by improper stacking / storage of the Balance Trainers. All plastics and Vinyl in this case are made from oil. When you stack the trainers where the blue ball portion is touching a black base of another unit, it will pull oil out of the ball. This is normal and goes away once washed with a mild cleaner and stacked base to base or dome to dome.

The dome of the Balance Trainer is constructed of high-quality vinyl, so you shouldn’t have any issues with latex allergies when using the product. 

The Balance Trainer is designed to perform a wide variety of exercises with either the dome side up or black platform side up, “Both Sides Utilized.” However, standing on the platform side of the Balance Trainer is not recommended, as this information is also stamped on the bottom of the unit. Standing on the dome side offers a balance challenge with the least risk or injury. Overall, before beginning this or any exercise program, consult a physician or health professional for recommendations, and be sure to read the owner’s manual included with your unit. 

Inflate the Ballast® Ball between 21” and 25” off the floor. Or, if using a stability ball tape measure, inflate the product between 55 cm and 65 cm. That way, you are able to accommodate your individual height requirements.

For club settings, a single size ball eliminates the need to purchase different sizes. Participants simply pick the ball that “feels” the best to them based on its inflation level. Watch how to inflate a Ballast® Ball here.

The material inside the Ballast® Ball is a secret! However, it is a safe, specially formulated mixture of dynamic material that both optimizes the rate of flow (internal shifting of MDL) inside the ball and provides enhanced audible feedback for lifting and shifting exercises.
