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 first chain wrapped around the upper and lower central sprockets has its free end connected to the drive arm and a pair of second chains each wrapped around an outer sprocket in the opposite direction have their free ends connected to the weight lever member. When the drive arm is pushed pivotally outward by a force on the handlebar, it pulls the first chain down causing rotation of the upper central sprocket and outer sprockets which causes the second chains to pivot the weight lever member upward raising the weights at the outer end thereof and the weight thereof resisting the outward force applied to the handlebar.
