An elastic resistance band that is fabricated by placing two end couplers on each end of a section of elastic resistance material. A pre-tensioned force is applied by incorporating a rigid tensioning member between the two end couplers of the resistance band. The resistance material is stretched during the assembly process, placing the material in a pre-tensioned state. By pre-tensioning the material, the resistance band then provides a more linear force to the end user. The rigid tensioning member is a telescoping assembly, wherein the resistance band is placed within an interior section of the telescoping assembly. The telescoping assembly comprises a plurality of telescoping tubular members slideably engaged with each other. An expansion end wall aperture and an interior surface of a groove are provided to retain an axial linear motion between telescoping tubular members.
