ABSTRACT:
An exercise device for performing isometric exercises comprises a pair of vertical exercise bars, slidably mounted on a frame so that the spacing therebetween is adjustable. Each of these exercise bars mounts respective ring-shaped exercise handles. The exercise handles are rotatable, about a horizontal axis, and are movable, both vertically, along the bars, and rotatably, about the bars, to permit adjustment to virtually an infinite number of positions.
The exercise device permits an improved form of isometric exercise, which is dynamic, rather than static. By applying force to the exercise handles or bars, and maintaining muscle tension as the user moves in a smooth, fluid motion to change his body position, the user's muscles are isometrically exercised throughout a continuous range of positions.
