Combine the BOSU Balance Trainer with BOSU POWERSTAX to elevate the surface by four inches, challenging advanced level exercisers, or simplifying accessibility for older and deconditioned participants.

Also, on its own, and when filled with two to 35 pounds of water, BOSU POWERSTAX transforms into an unpredictable resistance tool. Sold as a single unit.  Manufactured in the USA. BOSU Balance Trainers sold separately.
