ABSTRACT:
An adjustable weight-training apparatus is provided having a plurality of weight plates, each of the weight plates including a protrusion. The weight-training apparatus has longitudinally opposing ends, each of the ends having longitudinally outer and inner groups of weight plates. A rotatable bar is also included in the apparatus and includes an inner control shaft and an outer control shaft. The inner control shaft is configured to rotate within the outer control shaft. The rotatable bar is configured to rotate within central holes of the weight plates. The inner control shaft has a first plurality of longitudinally spaced lobes. The inner control shaft is rotatable to position selected ones of the first plurality of lobes in engagement with the protrusions of selected weight plates of at least one of the outer groups of weight plates. The outer control shaft has a second plurality of longitudinally spaced lobes. The outer control shaft is rotatable to position selected ones of the second plurality of lobes in engagement with the protrusions of selected weight plates of at least one of the inner groups of weight plates.
