ABSTRACT:
A multi-lifting weight apparatus is shown to enable the user to perform power squat lifts to develop leg strength throughout the hips, thighs and calf leg muscles, while at the same time eliminating back injuries to the user. The user is provided with a waist harness having a heavily padded belt furnished with both front and rear straps suspended from the belt down between the legs of the user. The lower ends of the straps are joined by a connector that supports a tension member that carries a roller assembly. This apparatus includes an elevated rack with a three-sided hand rail and a pair of platforms separated by a well section. The user stands on the platforms straddling the well section. Steps are formed at one end of the platforms serving as an entrance at the rear for mounting and dismounting the platforms. The front of the rack has a structural extension providing a raised horizontal pivot or fulcrum for an elongated lever that operates in a vertical plane that includes the well section. A pivoted lever arm is located under the elongated lever for supporting various weights at the front of the rack. A tension member restrains the pivoted lever arm to create a negative mechanical advantage as the elongated lever is raised. The roller assembly of the waist harness engages under the elongated lever beneath the standing position of the user and is capable of free movement therealong. Exercises other than power squats can also be performed when using this apparatus.
