Exercise device

Abstract

An apparatus for exercising an individual's muscles, including a hollow housing having a central hollow cylindrical section and a flange at one end of said cylindrical section. The flange end of the housing is mounted to a wall and an elbow joint permits the housing to be pivoted with respect to said wall. The side of the housing opposite the flange is provided with a support surface. An airtight disc or piston is movably positioned within said cylindrical section and is movable along a longitudinal axis of said cylindrical section. A rod extends from the center of a piston through said support surface and terminates in a handle. A cover plate which faces said support surface is removably attached to said rod; and a series of replaceable suction cup are fastened onto said cover plate which faces said support surface. In use an individual pulls on said handle and must first overcome the holding force of said suction cup before the movement of said handle is resisted by a nearly constant force of a vacuum forming within said cylindrical section between said flange and said piston.
