An abdominal exercise device is disclosed which comprises a base support member assembly upon which the user sits, a vertical resistance and restorative force member assembly mounted on the base support member assembly, and an arm support member. The arm support member positions the body of the user in an upright position. The invented exercise device permits the user to train and strengthen the major and minor muscles of the upper and lower back, to train the frontal portion of the midsection, the abdominals, the obliques to avoid spinal compression and to maintain decompression of the spinal vertebrae.

[ What is claimed is:] [6.] An abdominal exercise device comprising in combination a U-shaped upper body--arm support member substantially extending around the upper body of the user, a base support member assembly upon which a user can sit while exercising and containing a support structure assembly to support a vertical resistance and restorative force member assembly vertically from the base support member assembly, a vertical resistance and restorative force member assembly containing an energy storage device and an attachment structure to attach the vertical resistance and resistance force member assembly to said U-shaped upper body--arm support member, wherein the energy storage device of the vertical resistance and restorative force assembly comprises a vertical column which pivots on a ball-and-socket joint of the column and the vertical column is encased in an elastomeric material resistant to deformation stress, said elastomeric material flexing and storing and releasing energy in response to application and removal of force by a user of the U-shaped upper body--arm support.
