Ballstep Group Balance Board - made in Germany - for increased stability and dynamics. With four balls underneath the wooden board, it allows users of all fitness levels to engage in sensory-motor training and progressively enhance their skills. The wooden rings around each of the four balls prevent the Ballstep from shifting during dynamic use. The training delves deeper, improving perception, stimulus processing, and stability. Beneath the specially designed plate are four extremely robust air-filled balls. Unlike conventional balance boards or steppers, the standing surface is designed to be floating and unstable due to this unique construction. Technical specifications: Dimensions: 89 x 43 x 14 cm Weight: 5,250 g Load capacity: approximately 150 kg.
