An exercise chair is disclosed having an adjustable height that functions to exercise the lower body by progressively lowering the height of the seat. By lowering the height of the seat, the user will increase the amount of muscle activation and therefore facilitate lower extremity strengthening. The seat of the exercise chair can be adjusted between 24 inch maximum height to 12 inch minimum height from the floor. The chair may be used as a therapy chair by a therapy professional or by an individual who wants to exercise his or her lower extremities or to facilitate standing by a seated individual.
