ABSTRACT:
An exercise device for exercising all of the major muscles comprising the upper and lower abdomen and back, while avoiding undue stress on the lumbar and cervical spinal discs and the muscles comprising the lower back and hip flexors. The device provides rigid upper and lower back supports which are pivotally joined at a point which restricts flexure of the spine to the T10-L1 region. Resistance means attach to the pivotal portions of the device to allow adjustable resistance to exercise motions.
