Abstract

An abdominal exercise device to assist in exercising all three abdominal muscles includes a platform which is placed on a flat supporting surface. A substantially U-shaped body cage is pivotally mounted on the platform and extends outwardly therefrom and includes a U-shaped neck and head support portion and a pair of platform connecting portions adjustable connected thereto. A padded cushion mounted on the support portion supports the head of the user. A pair of pivot members pivotally connect the body cage to the platform. Each pivot member includes a cylindrical portion for pivotally rotatably mounting the body cage to side walls of the platform, and a semispherical portion which connects to free ends of the body cage. A user reclines on the platform and grasps the body cage and performs a sit-up type of motion with the body cage ensuring a full range of motion in the proper plane of movement to maximally recruit the abdominal muscles.
