1. A plyometric device comprised of:
- at least one outer four-sided structure and at least one inner four-sided structure wherein said outer four-sided structure and said inner four-sided structure are telescoping;
at least one rod having a cylindrical face;
wherein at least a first side and a second side of said inner structure have at least one slot having a diameter equal to or larger than said cylindrical face of at least one rod;
wherein at least two sides of said outer four-sided structure have a plurality of circular contours , wherein said circular contours are adjoined by a straight segmented contour and wherein said straight segmented contour is down-ward sloping;
wherein said series of contours begins at an angled upper surface and ends at an angled lower surface;
wherein said semi-circular contours have a radius equal to or larger than said cylindrical face of at least one rod; and
wherein each of said downward sloping contours have a uniform angle between twenty and seventy degrees to guide said one rod in an upward and laterally outward direction.

Abstract
The present invention is a telescoping plyometric exercise device which can be rapidly adjusted for height using a single lifting motion. The apparatus is incrementally height-adjusted and secured in a position capable of withstanding force. The apparatus requires a single lifting motion to securely and incrementally adjust the device, and to balance impact and force through the use of novel, contoured inner components and structural assemblies. These inner components and structural assemblies are engineered to provide the capability for rapid height adjustment of the apparatus.
