Stretching and exercise device
First Claim
1. An exercise device comprising:
- a) a platform formed of a rigid material, said platform structured and disposed for supporting an exerciser'"'"'s body weight thereon;
said platform including a top region, a bottom region, a first end zone and a second end zone,b) said top region of said platform defining an upper support surface for contacting and supporting the exerciser thereon;
said upper support surface having a generally sinusoidal configuration between said first and second end zones, said upper support surface further including;
i) a convex support portion for supporting a substantial portion of the exerciser'"'"'s back, said convex support portion causing the exerciser'"'"'s back to at least partially arch when the exerciser reclines against said convex support portion;
ii) a concave cradle portion for supporting and cradling the exerciser'"'"'s buttocks during the performance of exercises on said device;
c) said bottom region defining a bottom surface having a generally sinusoidal configuration between said first and second end zones corresponding said generally sinusoidal configuration of said upper support surface; and
d) said bottom region of said platform structured and disposed to contact and support said device on a common planar surface when said device is in an operative position.

Abstract
A portable, easy to use exercise device suited for various types of sit-up type exercises to increase muscular flexibility and generally strengthen the abdominal and back muscles while substantially minimizing stress to the lower back region. The exercise device includes a platform formed of a rigid material structured for supporting an exerciser'"'"'s body weight. The platform includes a top region, a bottom region, a first end zone, and a second end zone. The top region of the platform defines an upper support surface for contacting and supporting the exerciser. The upper support surface has a generally sinusoidal configuration between the first and second end zones. The upper support surface includes a convex support portion for supporting the exerciser'"'"'s back so as to cause it to partially arch when the exerciser reclines back. The upper support surface further includes a concave cradle portion for supporting and cradling the exerciser'"'"'s buttocks during the performance of exercises. The bottom region defines a bottom surface having a generally sinusoidal configuration between the first and second end zones and corresponding to the generally sinusoidal configuration of the upper support surface. The bottom region of the platform is structured to contact and support the device on a common planar surface when the device is in an operative position.
