Claim:
A portable exercise device, comprising: a main tube having an adjustable length; said main tube including a central tube, a first outboard tube connected to a first end of the central tube and a second outboard tube connected to a second end of the central tube; said central tube screwthreadedly engaging said first outboard tube and said second outboard tube so that rotation of said central tube in a first direction causes said first and second outboard tubes to travel away from one another, thereby increasing an overall length of said main tube and so that rotation of said central tube in a second direction opposite to said first direction causes said first and second outboard tubes to travel toward one another, thereby decreasing the overall length of said main tube; a first door jamb gripping device secured to an outermost end of said first outboard tube; a second door jamb gripping device secured to an outermost end of said second outboard tube; each door jamb gripping device being adapted to engage a door stop of a door jamb at any preselected height along an extent thereof; a first handle rotatably secured to said first outboard tube; a second handle rotatably secured to said second outboard tube; a first pulley rotatably mounted in a hollow interior of said first outboard tube; a second pulley rotatably mounted in a hollow interior of said second outboard tube; a third handle unconnected to said main tube; a fourth handle unconnected to said main tube; a first elongate resistance band having a first end engaged to said third handle, a second end engaged to said fourth handle, and a medial part positioned in a hollow interior of said main tube that engages said first and second pulleys; whereby exercises may be performed when an exerciser is gripping said first and second handles or said third and fourth handles.
