ABSTRACT:
A free weight lifting system utilizes a lifting bar with an inboard region to be gripped by a weight lifter and opposed ends which can receive and support one or more weights to be lifted. A first pair of spaced apart upright members are positioned in a first longitudinally extending plane and a second pair of spaced apart upright members positioned in a second longitudinally extending plane, the first and second planes being spaced apart and generally parallel. A first yieldable cord extends between the first pair of upright members and a second yieldable cord extends between the second pair of upright members. In one mode of operation, the lifting bar is positioned beneath the elastic cords. When it is raised by the weight lifter, an upper surface of the bar is engageable with the yieldable cords at spaced locations such that progressively increasing resistance is imparted to the weight lifter. In another mode of operation, the lifting bar is positioned above the yieldable cords. When the bar is lowered by the weight lifter, a lower surface of the bar is engageable with the yieldable cords such that progressively increasing assistance is imparted to the weight lifter. In order to minimize friction between the bar and the cord during the lifting operation, rolling sleeves are provided on the bar which are engageable with the yieldable cords. The entire system may be size adjustable to accommodate all sizes of weight lifting equipment.
