Abstract
Abstract An exerciser is provided in the form of an armchair having a body-carrying seat member mounted on the chair for rotary reciprocating motion about a vertical axis relative to the chair including its legs, back and arms. Power driving mechanism is provided for effecting the rotary reciprocating motion of the seat member so that a person sitting on the seat will have imparted to his buttocks a movement which will exercise his leg muscles when his feet are on the floor, his arm muscles when his arms or hands are engaging the arms of the chair and his back muscles through his arms or directly if his back is against the back of the armchair.
