ABSTRACT:
An exercise device attachable to the chair is provided which comprises a generally “W”-shaped frame separately mounted on a post of a height-telescopic executive type chair, an elastic band disposed and extending through the W-shaped frame, and a tension adjusting mechanism mounted on the chair and connected to the elastic band. The adjusting mechanism is manipulated to adjust the tension of the elastic strap. The exercise device mounted on the executive chair creates a unique and most serious exercise-station at one's home or office. The tension adjusting mechanism slides up and down with the motion of the chair, and by this action the tension of the elastic band increase or decrease significantly, making the workout routine a challenge or pleasure as per one's choice.
