ABSTRACT:
An abdominal exercise device comprising a frame, a seat support fixed to said frame, a back support pivotally connected to the frame near the seat support and being disposed at a negative incline during a portion of its use, and one or more handlebars pivotally mounted to the frame and in operational contact with the rear surface of the back support for causing the back support to pivot away from the negative incline if desired by a user during the exercise. The machine may also comprise lever members fixed to the angular orientation of the handlebars and in contact with the rear surface of the back support for lifting said back support during a portion of the exercise if desired. In a preferred embodiment, the handlebars are pivotally mounted to the frame at location separate and distinct from the where the back support is connected to the frame so that the user can use the handlebars, if desired, to create a mechanical advantage in moving the back support during a portion of the exercise. Where there are two handlebars, they may also be connected to each other at one end and the user may disconnect them to provide a gated entry for the user before and after exercising.
