US Patent 10183194 Rebound and balance training device

A rebound and balance training device includes a frame, a footboard, a carrier for the footboard and a plurality of resilient spring elements extending between and attached to the frame and the carrier to support the footboard above a supporting surface. A user standing on the footboard manually effects repeated vertical bouncing movement between upper and lower positions. The distance traveled by the footboard, the effort required to effect movement, and the stability thereof may be modified by selectively modifying the number, the length, the position, or the elasticity of the resilient elements. In one embodiment, a pair of footboards is employed to simulate skiing movements.
