Claim:
1. A rebound and balance training device supported on a floor operable in response to action of a user standing thereon comprising: a frame having a plurality of spaced lower uprights with bottom ends, a pair of elevated horizontal hanger portions at opposite sides, and a plurality of upper uprights extending above said hanger portions, a handle on each of said upper uprights extending outwardly therefrom that may be gripped by a user, said handles being movable between and releasably securable at a plurality of positions; a rigid footboard below the level of said hanger portions and having spaced side edges, spaced forward and rearward edges, and a horizontal planar upper surface intermediate said side edges and intermediate said forward and rearward edges defining an interior surface area having a constant width extending between a point adjacent one side edge and a point adjacent the opposite side edge and a constant length extending between a point adjacent the forward edge and a point adjacent the rearward edge at least spanning the area underlying both feet of a user standing centrally thereon to provide full support under each foot; a plurality of resilient spring elements with upper and lower ends extending between respective side edges of said footboard and said hanger portions for suspending an unloaded footboard horizontally at an upper height below said hanger portions, a lower height closely adjacent the floor when the user is standing thereon and applying downward force, and an intermediate height between the upper and lower heights when the user is standing thereon and not applying downward force, said spring elements being of equal length and having a spring constant in a range between 0.25 and 2.5; a plurality of fasteners for connecting said spring elements with said hanger portions including separable cooperating fastener parts respectively carried by said spring element upper ends and said hanger portions with said hanger fastener parts defining more than two spaced connection points on each hanger portion for said upper end fastener parts; a plurality of fasteners for connecting said spring elements with said footboard including separable cooperating fastener parts respectively carried by said spring element lower ends and said footboard with said footboard fastener parts defining more than two spaced connection points for said lower end fastener parts at each side of the footboard; and, whereby the user stands on said footboard and may extend said spring elements and effect reciprocal vertical motion of said footboard by applying force on said footboard and whereby spring elements may be added or removed to adjust overall spring force in accordance with a user's weight and the forces the user applies.
