Abstract
The abdominal exerciser device is made of a one piece skeletal frame. The frame defines a pair of support rails, a pair of arcuate rocker portions, a pair of arm rest portions and an upstanding arch-shaped portion connecting the support rails together. Removable cushions are disposed on the arm rest portions to receive the elbows of the user when in a supine position. The head and neck of a user are supported on a support extending across the arch-shaped portion. The rocker portions are curved on a circular arc to mimic the curvature of the spine of the user.
