An apparatus for exercising the muscles of the lumbar region of a subject's back includes a seat, a vertical support member to which the back end of the seat is attached so that the centerline extending from the from the front to the back of the seat forms an angle with the vertical member in the range of 65 to 75 degrees and with the front end of the seat being inclined downward to the surface on which the vertical support member stands, a base attached to the bottom end of the vertical support member, a cylindrical roller pad that is rotatably mounted to the vertical support member at a position above the seat, a knob that is adjustably mounted to the vertical support member, and a hand-held weight which the subject grasps and holds near the subject's body while performing the strengthening exercises. In a first embodiment, these entail the subject sitting on the seat and assuming a first position with subject's upper torso bent over so as to be proximate the thighs and a hand-held weight grasped and held near the subject's chest. The subject then moves to a second position by raising the upper torso while continuing to hold the hand-held weight near the subject's chest and keeping the pelvis and sacrum in contact with the pad. A preferred angular range of motion of the subject's back while so exercising is approximately seventy-two degrees. In a second embodiment, the exercises entail the subject standing with a hand-held weight near the hip and with the sacrum against the knob so as to keep the hips and pelvis from moving while the subject does lateral, upper body bending exercises.
