Abstract: An apparatus and a method for combiningly performing four important exercises localized to the lower back with the addition of weight resistance: a) the rotation or torsion of the lower spine and the lower back muscles; b) the bending of the spine forward and the exercising of abdominal muscles; c) the bending of the spine rearward and the exercising of the lumbar and erector muscles; d) the stretching and self-postural adjustment of the spine. The user performs the four exercises in the horizontal position with both legs in raised position. A swinging member accommodates the legs and allows the swinging, side-to-side motion of the legs. A second pivotal member helps the bending of the pelvis forward and rearward. A roller support assembly supports and massages the entire back during exercises. The user's body rests on an anatomical cushion support during exercises.
