ABSTRACT:
An exercise machine facilitating performance by human beings of a wide variety of muscle strengthening and toning exercises comprises a vertically elongated open frame of sufficient height for an average individual to stand inside. Weight trucks holding a selected total weight are vertically rollable on vertical members of the frame, and are coupled via cables running over pulleys on opposite lateral sides of the frame to individual pull handles, a single handlebar, or a single footbar, depending on the exercise being performed. Movement of the cables is resisted by the force of gravity acting on the weight trucks. The exercise machine includes a bench having a front seat section joined by a lateral hinge to a rear back rest section, and is adjustable in height and inclination, or removable entirely from the machine, to permit an individual standing or seated in a wheel chair within the frame to perform various exercises. A leg exercise attachment pivotably attached to front of the frame of the exercise machine is pivotable in a vertical plane. A selected resistance force to pivotable motion of the leg exercise attachment is provided by the weight truck via a cable running over front and rear upper pulleys to diagonal, horizontal and vertical pulleys, respectively, and then to the bottom of the leg exercise attachment.
