ABSTRACT:
A fitness sled exercise machine wherein a client user may, with the cooperative force of arms and legs, elevate a body carriage or sled, tracking on a rail attached to a frame base and foldable standard, from an at rest position to a point of elevation. The user may elect a front or rear facing exercise position to accomplish the elevation task. Body weight provides the primary resistance to elevation, supplemented by additional weights and/or the resistance of a stroke adjustable hydraulic cylinder.
The specified frame standard is 90 degrees foldable for shipping, but may be locked in vertical position for operation. In the latter position, the standard supports a pulley and line lift apparatus that provides the user with an approximate 4:1 leverage advantage for upper limb manipulation of that apparatus. A system of levers and couplers serve to join the lift assembly to the sled and to foot bars located at the front and rear of the machine for lower limb participation in the elevation task.
