Abstract
An apparatus for exercising abdominal muscles comprises a load cable which is received by a pulley. The pulley is connected to a structure through a connector, and a single handle is connected to the first end of the load cable. A neck collar is connected to the second end of the load cable. In the method of exercising, the user lays on a surface and contracts the abdominal muscles to raise the torso no more than halfway to the normal position. Concurrently, the user pulls the handle such that a load is communicated between the handle and the neck collar to assist the abdominal muscles in raising the torso.
