Disclosed herein is an exercise chair for aiding in the alleviation of lower back pain. The chair device of the present invention comprises a central post portion defining a central axis with a base at one end and a coupling portion fashioned to be tilted relative to the central axis at the other end. A coil spring is concentrically located on the central axis and affixed to the post portion at the one end and to the coupling portion at the other end. The coil spring is normally biased to maintain the seat of the chair in a non-tilted position. Also disclosed herein, is a method of practice employing the chair device. In the method, a user in a seated position on the chair selectively and reversibly rotates their pelvic/hip region in three possible dimensions about a point of origin substantially centrally located to their pelvic region in various directions resulting in stretching and strengthening exercises of the abdominal, lumbar and pelvic/hip regions of the user.
