Claim:
An exercise apparatus for use in performing abdominal exercises comprising: a) a back support member having a first side for supporting a back of a user; b) a headrest having a first side for resting a head of a user there against; c) a cradle supporting said headrest and a tension spring directed upwardly from said back support member at an angle between a horizontal surface and ninety degrees from said horizontal surface, said tension spring having one end connected to said cradle and an opposite end connected to said back support member for allowing said cradle and headrest to pivot under a weight of said head of the user and; d) a first extension connected between said tension spring and said back support member, said first extension comprises: i) a guide track having a plurality of apertures extending there through along a length thereof positioned on a side of said back support opposite said first side; ii) a first extension rail having a plurality of apertures extending there through and along a length thereof; and iii) a first locking pin, wherein said first extension rail is received by said guide track, and upon extending said first extension out from a first end of said back support member, and aligning said apertures of said guide track and said first extension rail, said first locking pin is received through each of said aligned apertures thereby locking said first extension in place; e) a second extension connected between said cradle and said headrest, said second extension comprising: i) a U-shaped connection bracket positioned on a side of said headrest opposite said first side, said connection bracket having an aperture extending through each wall of said U-shaped bracket; ii) a second extension rail having a plurality of apertures extending there through and along a length thereof; said rail secured to said cradle by a securing pin which passes through a securing aperture of said cradle and a securing aperture of said second extension rail whereby the second extension rail is securable in a central position to the cradle by the securing pin, or a forward position to the cradle by the securing pin or a back position to the cradle by the securing pin thereby causing the users head to be positioned further from the abdomen thus allowing a user to exercise in a near prone position; iii) a second locking pin, wherein said connection bracket is slidably connected to said second extension rail and upon positioning said headrest at a desired distance from said cradle and aligning said apertures of the connection bracket and said second extension rail, said locking Din is received through each of said aligned apertures thereby locking said second extension in place and said headrest being pivotable about said second locking pin allowing for an adjustment of an angular position of said headrest.
