A bounce board exerciser

摘要: The exerciser consists of a platform (24) suspended on springs (32) and connected to an adjustable damper (46) for dissipating energy. assembly is constructed have resonant frequency which matches the tempo bouncy popular tunes remains same regardless weight user: user first sets his then makes oscillate by flexing knees exerting pressure handle (67) moves in synchronism with, but oppositely (24). unit can be use one or two persons. In embodiment, fastened at end lever frame (25), other pivoted. elastic movable sled (31) whose position determined user's weight. embodiments, compressed coils spring (71) employed. Dissipation provided shock absorbers (46).
