Abstract:
A pull down apparatus is provided. The pull down apparatus includes a selectable weight mechanism and a support member which pivotably supports a pair of four-bar linkage mechanisms. The four-bar linkage mechanisms are pivotably mounted at their rearward ends about axes which are disposed at an angle relative to a horizontal plane, i.e. are tilted relative to vertical, such that a pair of elongated bars of the four-bar linkage mechanisms travel in planes which are tilted relative to vertical. The tilted planes through which the four-bar linkage mechanisms travel enable the handles to travel along a slightly curvilinear downwardly diverging path which simulates as natural a human musculoskeletal upward pushing motion as possible.
