WHAT BOSU® PRODUCT IS RIGHT FOR ME?
Not sure which BOSU® product is right for you? Read this article to see which one is the right fit for you.
HOW DO I GET THE PLUG OUT OF MY BOSU®?
To avoid harming the valve and surrounding area, we suggest using a spoon to remove the plug from both the BOSU® Balance Trainer and BOSU® Ballast Ball. A second option is to purchase the offical BOSU® Plug Puller is designed to remove BOSU® Balance Trainer plugs (right side of tool) and BOSU® Ballast® Ball plugs (left side of tool) with ease, and without causing damage.
WHAT IS THE PROPER INFLATION FOR THE BOSU® BALANCE TRAINER (COMMERCIAL AND HOME VERSIONS)?
Inflate the BOSU® 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.
WHAT IS THAT "BREATHING" AIR NOISE WHEN I STEP ON MY BALANCE TRAINER?
After inflation, it is normal to hear a "breathing" air noise coming from the base of your balance trainer. It is a normal occurance as the dome settles on the platform base and does not mean your balance trainer is leaking air. However, if you are having to reinflate your balance trainer - please contact us.
HOW DO I FIX A PUNCTURE/HOLE IN MY BOSU® BALANCE TRAINER?
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.
THE DOME OF MY BOSU® BALANCE TRAINER PULLED OUT OF THE BASE. WHAT DO I DO?
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 BOSU® 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.
HOW DO I STORE MY BOSU® BALANCE TRAINER?
Store your BOSU® 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.
MY BOSU® BALANCE TRAINERS ARE LEAKING AN OILY RESIDUE. WHAT DO I DO?
The oil is caused by improper stacking / storage of the BOSU® 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.
CAN I USE THE BOSU® BALANCE TRAINER IF I HAVE A LATEX ALLERGY?
The dome of the BOSU® Balance Trainer is constructed of high-quality vinyl, so you shouldn’t have any issues with latex allergies when using the product.
CAN I STAND ON THE PLATFORM SIDE OF THE BOSU® BALANCE TRAINER?
The BOSU® 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 BOSU® 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.
WHAT IS THE PROPER INFLATION FOR THE BALLAST® BALL?
Inflate the BOSU® 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 BOSU® Ballast® Ball here
WHAT IS THE WEIGHTED MATERIAL IN THE BALLAST® BALL?
The material inside the BOSU® 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.
