Abstract
Abstract An exercise machine with a seat and two adjustable cranking mechanisms is disclosed. The first cranking mechanism has rotatable hand grips for grasping by the user's hands while the second cranking mechanism has rotatable pedals for engagement by the user's feet. This second cranking mechanism is located at a position vertically above the location of the seat. Therefore, the exerciser may not use his or her body weight when exerting pressure on the pedals. This machine exercises virtually all of a user's muscle groups, however, the configuration of the seat vertically below the second crank mechanism results in a particularly strenuous activity for a user's hamstrings. Additionally, each cranking mechanism is selectively adjustable to a plurality of exercise positions. This makes the machine adaptable to all exercisers regardless of their size and shape and permits the user to selectively vary the exertion required during the exercise.
