Abstract

An abdominal exercise cushion for enabling the performance of safe and effective abdominal exercises, said cushion, comprises a yieldable back support device comprising pillow-like main body portion having an anchoring panel extending from a front side of the main body portion, the main body portion having a three dimensional configuration with a base surface and a back engaging support surface with a height sufficient to at least engaging a persons lower back for yieldably engaging and supporting a person in a partially backwardly inclining position, the anchoring panel formed of a pliable fabric panel secured along a front edge of the main body portion between the base surface and the support surface and adapted to be positioned to the front side of the main body for sitting on while inclining on said main body portion.

Claims

1. An abdominal exercise cushion for enabling the performance of safe and effective abdominal exercises, said cushion comprising:

an elastic back support device comprising a pillow-like main body portion and an anchoring panel extending from a front of said main body portion, said main body portion having a three dimensional configuration with a generally planar base surface adapted to rest on a horizontal support surface, opposing side surfaces, a back surface and a front surface extending upward to a top surface, said front surface defining a back engaging support surface extending upward from said base surface at said front, said foam block having a length of between nine to fifteen inches and a height of between eight to twelve inches, thereby providing a support surface having a height sufficient to engage a person above the person'"'"'s pelvis and below about mid back when in about a sixty degree inclined position from the vertical and to support the person'"'"'s upper body inclined at about a thirty degree position from the horizontal, with a height sufficient for yieldably engaging a lower back of a person and supporting said person in a partially backwardly inclining position, said anchoring panel having top and bottom generally parallel surfaces and formed of a pliable fabric panel secured along an edge of said front of said main body portion between said base surface and said support surface and adapted to be positioned to said front of said main body for sitting on while inclining on said main body portion.

2. An exercise cushion according to claim 1 wherein said support surface is covered by a pliable panel of fabric secured along a bottom edge to a forward edge of said bottom surface and along a top edge to a top edge of a rear surface.

3. An exercise cushion according to claim 1 wherein said anchoring panel is padded with up to about one inch of foam.

4. An improved method of abdominal exercise, comprising the steps of:

selecting an elastic support cushion as defined in claim 1;

placing said support cushion on a planar support surface positioning said anchoring panel to said front of said main body;

sitting on said anchoring panel on said support surface adjacent said and reclining against said cushion; and

,

performing abdominal crunches while at least partially supported by said cushion.

5. A method of according to claim 4 wherein performing abdominal crunches while at least partially supported by said cushion comprises performing said crunches within a range of angles of between about thirty and sixty degrees.
