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.

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.

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. 
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.
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.
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 official BOSU® Plug Puller is designed to remove BOSU® Balance Trainer plugs (right side of tool) and BOSU® Ballast® Ball plugs (left side of tool) without causing damage.
