ABSTRACT:
A portable exercise device is provided which is completely self-contained, requiring an anchoring, bolting or other attachment to a wall, floor or other structure during use. The device is four sided, usually square, and may be readily dismantled for shipment or storage. The two uprights or vertically oriented sides of the device each include two concentric telescoping parts, spring-urged to cause one part to totally surround and encompass the other part. The top portion or action bar of the device is connected to one part of each of the uprights, and the base portion is connected to the other part of the uprights. The top and bottom portions are parallel to and movable relative to each other. The device is particularly appropriate for use in exercises where the bottom portion (base plate) is body-anchored, while the action bar is pulled or pushed for performing isometric exercises.
