A weight training device for providing substantially uniform resistance throughout the range of motion of each of a variety of weight lifting exercises. Upstanding front and rear stanchions are attached to front and rear portions of a base, respectively. In a first embodiment, the front stanchion is rigidly attached to the base, the rear stanchion is pivotally attached to the base, and a lever arm assembly is pivotally attached to the front stanchion and includes a dolly cage attached to the rear stanchion that forces the rear stanchion to pivot toward and away from the front stanchion as the assembly is pivoted in a vertical plane by a weight trainee against the resistance of weight suspended from the assembly. In a second embodiment, the front stanchion is mounted for reciprocal, vertical motion on a rod attached to the base. A plurality of weight plates are disposed below the front stanchion in vertical, stacked relation, any or all of which can be suspended from the front stanchion by insertion of a stack pin through any one of the plates and into an aperture in a stack pin rod suspended from the front stanchion. A lever arm assembly has a front portion pivotally attached to the front stanchion and a rear portion pivotally attached to the rear, pivoting stanchion, such that when a trainee pivots the assembly in a vertical plane against the resistance of the weights, the rear stanchion pivots toward the front stanchion.
