ABSTRACT:
A straight back side chair has a seat cushion and a back member, and includes a low resistance loading device that is operated through a system of cords and pulleys from handgrips. The pulleys are supported on arms that are mounted to the back of the chair and which can be selectively positioned for different types of exercise. The arms can be positioned laterally out from the sides of the chair for doing butterfly type exercise; pushed downwardly at an angle for curls; or positioned overhead above the back of the chair for permitting a person seated in the chair to do pull downs. When the chair is not in use as an excerciser, the arms are folded out of the way so it functions as a side chair and does not visually intrude on the usable space in a room or tend to give the room the look of a gymnasium. The force resistance device is very compact so that it takes little space beneath the seat, permitting a cushioned or padded seat to be used. A panel having a display of counters, force indicators and the like can also be mounted on the chair seat and made to be retractable when not in use.
