Abstract

The disclosed invention provides an abdominal exerciser comprised of a padded bench with an adjustable arc shaped lumbar support mounted to a tubular support frame. The radius of the lumbar support is slightly larger than the radius of ordinary spinal arching. The lumbar support fully extends the lumbar section of the spine decompressing the intervertebral space while stretching the abdominal muscles and neutralizing the lumbar muscles in preparation for a sit-up or legs-up movement in which the spine is fully supported. Adjustably attached on either side of the lumbar support are two generally semicircular shaped side extensions. The support frame includes a base, two feet, and an arc shaped extension with a plurality of parallel footrests. The support frame also includes a hinge about which the bench rotates through the arc of the extension to adjust the inclination angle of the bench.
