The chair back has two or more exercising devices embodied therein with a pair of handles extendible from the back of the chair. A head band strap attached to the chair back frame is used for neck exercising and gripping support for abdominal and leg exercises. In each chair arm is located a handle extendible from the chair arm when grasped by a seated person. The chair side frames in the seat have pulling devices similar to those in the chair back and arms and are also used to exercise the arms. Rubber caps are formed in the chair arm ends for hand squeezing and gripping support. An extendible exercise frame with a pedal device can be folded inward and stored against the front chair legs. Two spring clamps are affixed to the two front legs to hold the frame and allow it to be swiveled forward and extended for exercising and backward for storage.
