Abstract:
1. A method of exercising with a support system having a fulcrum about which a user's body may pivot while bending between a lowered orientation and a raised orientation, the method comprising the steps of: providing a one piece pillow, the pillow having a rectangular lower surface with a linear forward edge and a parallel rearward edge, the forward edge and rearward edge being spaced by a length of 9 inches, plus or minus 10 percent, the lower surface having lateral side edges perpendicular to and coupling the forward and rearward edges, the side edges being spaced by a width of 10 to 16 inches, plus or minus 10 percent, the lower surface being positionable horizontally upon a recipient surface during use; the pillow having an arcuate upper surface, the upper surface having a forward section formed with a continuous radius of curvature of 5 inches, plus or minus 10 percent, over the majority of its extent, the upper surface having a rearward section formed with a continuous radius of curvature of 15 inches, plus or minus 10 percent, over the majority of its extent, the pillow having a height between the upper and lower surfaces with the maximum height being 2.5 inches, plus or minus 10 percent, the upper surface having a high point located closer to the forward edge than the rearward edge with between 40 and 45 percent of the length of the pillow being forward of the high point and with between 55 and 60 percent of the length of the pillow being rearward of the high point; the pillow having similarly configured parallel side surfaces, each side surface being planar and having a linear lower edge co-extensive with one of the side edges of the lower surface, each side surface having a curved upper edge; the pillow being fabricated of closed cell ethylene vinyl acetate foam and having a limited resilience whereby the high point is depressed by between 15 and 20 percent of its height when a user weighing between 120 and 180 pounds lies upon the pillow; and supporting a user on the pillow; the pillow being adapted to support the user with the high point beneath one side of the user; and using the pillow as a fulcrum while lifting one portion of the user's body.
