Abstract
Abdominal exercise apparatus wherein upper and lower body supports are provided and interconnected to coordinate upper and lower abdominal workouts. Resistance for the abdominal exercises may also be provided by the apparatus. Further, the interconnection between the upper and lower body supports may be selectively disconnected so that individual upper and lower abdominal exercises can be performed.
Claims13
Abdominal exercise apparatus comprising:
- a base member adapted for support on a substantially horizontal surface;
- a generally planar seat pad fixed disposed generally horizontally on said base member;
- a foot support assembly pivotably mounted to said base member about a first horizontal pivot axis at a first side of said seat pad;
- a back support assembly pivotably mounted to said base member about a second horizontal pivot axis parallel to said first pivot axis and across said seat pad from said foot support assembly, wherein in its at rest position said back support assembly is substantially horizontal and line with said seat pad;
- interconnection means interconnecting said foot support assembly and said back support assembly for concurrent pivoting movement in opposite angular directions about their respective pivot axes;
- wherein one said foot support assembly and said back support assembly is configured to be directly disposed on the substantially horizontal surface in the at rest position of said apparatus;
- and
- whereby a user lyes in a supine position with his/her feet positioned on said foot support assembly and his/her back position on said back support assembly, and performs abdominal exercises.

- a base member adapted for support on a substantially horizontal surface;
- a generally planar seat pad fixedly disposed generally horizontally on said base member;
- a side frame secured along one edge of said base member and extending upwardly therefrom;
- a foot support assembly pivotably mounted to said base member at a first horizontal pivot axis transverse to said one edge and at a first side of said seat pad, said foot support assembly including a first member adjacent to said side frame and extending upwardly from said first pivot axis;
- a back support assembly pivotably mounted to said base member at a second horizontal pivot axis parallel to said first pivot axis and across said seat pad from said foot support assembly, said back support assembly including a second member adjacent to said side frame and extending upwardly from said second pivot axis;
- a first link bar having first and second ends and being pivotably mounted between its first and second ends to said side frame at a third horizontal pivot axis parallel to and between said first and second pivot axes;
- a second link bar having first and second ends and being pivotably mounted at its first end to the first end of said first link bar and at its second end to said foot support assembly first member;
- and
- a third link bar having first and second ends and being pivotably mounted at its first end to the second end of said first link bar and at its second end to said back support assembly second member whereby a user lyes in a supine position with his/her feet positioned on said foot support assembly and his/her back positioned on said back support assembly, and performs abdominal exercises.

Abdominal exercise apparatus comprising:
- a base member adapted for support on a substantially horizontal surface;
- a seat support frame secured to said base member and extending upwardly therefrom to define a generally horizontal seat pad support plane;
- a generally planar seat pad fixedly supported on said seat support frame at said seat support plane;
- a foot support assembly pivotably mounted to said base member about a first horizontal pivot axis at a first side of said seat support frame, said foot support assembly including a first member extending upwardly from said first pivot axis;
- a back support assembly pivotably mounted to said seat support frame about a second horizontal pivot axis parallel to and above said first pivot axis and across said seat support frame from said foot support assembly, said back support assembly including a second member extending downwardly from said second pivot axis;
- and
- a link bar having first and second ends and being pivotably mounted at its first end to said foot support assembly first member and at its second end to said back support assembly second member whereby a user lyes in a supine position with his/her feet positioned on said foot support assembly and his/her back positioned on said back support assembly, and performs abdominal exercises.
