Abstract: An exercise machine has a frame with a generally rectangular base and a platform disposed at an angle at one end upon which the user stands. A horizontal shaft rotatably mounted on a pair of vertical frame members near the forward end of the base has an upper central sprocket at its center and smaller sprockets at its outer ends. A lower central sprocket is rotatably mounted on the base. A weight support arm pivotally connected to a pair of upright frame members extends forwardly therefrom and a selected number of weights are received on the outer end thereof. An elongate lift arm pivotally connected to the vertical frame members extends angularly upward and rearward therefrom toward the platform and has a pair of shoulder pads at its outer end positioned a distance above the platform, with a first and second pair of lateral hand grips near each end of the pads for griping the bar in two positions.

Abstract: An exercise machine has a frame base with a platform at the rearward end upon which the athlete stands. A horizontal shaft rotatably mounted on a pair of vertical frame members near the forward end of the base has an upper central sprocket at its center and smaller sprockets at each end. A weight lever member pivotally connected to a pair of upright frame members extends forwardly therefrom and a number of weights are received on the outer end of the weight lever. A lower central sprocket is rotatably mounted between the upright frame members. A drive arm is arm pivotally connected at its bottom end to the platform. A handlebar rotatably mounted at the upper end of the drive arm is positioned a selective distance above the platform and has hand grips at each end.

A weight supporting member pivotally connected to a pair of upright frame members extends forwardly therefrom and a selected number of weights are received on the outer end of the weight supporting member. A pivot arm pivotally connected to the upright members extends forwardly therefrom and has an elongate lift arm secured thereto which extends angularly upward and rearward therefrom toward the platform. A hand grip bar at the outer end of the lift arm is positioned a selective distance above the platform has two sets of hand grips for griping the bar in two positions.
