The LiveProBosu Pro Balance Trainer LP8210 is the new and improved Balance Ball for greater intensity and durability. It’s markedly different from the Basic Ball in its dimensions, color and tougher exterior. It has a thicker bladder (Dome) and a rubberized, non-marking over-mold on the bottom platform (with no rubberized feet) for optimal grip on floors. It is virtually indestructible due to its quality and is designed for commercial use. The Pro Ball can be used with the platform side either up or down to challenge balance with different body positions. Product colour may vary from picture
