<p>An improved weight lifting assembly, such as a barbell (Fig. 6), incorporating a locking system comprising a buffer plate (30) having a locking key to serve as a securement means and randomly fasten weight plates (20) to the bar. The weight lifting assembly provides for a bar (17) and oversized weight plates (20) which fittingly interlock together in order to prevent the rolling, separation or spreading of the weight plates across or off the bar. Here, the weight plates have two opposing ends (22, 24) with a 50 % minimum clearance to allow the user to properly handle, lift and control the oversized weight plates. The present invention further includes a modified dumbbell (10) incorporating a mechanism for securing various weighted attachments thereby allowing a user to use one dumbbell for multiple degrees of weight. The modified dumbbell herein generally comprising an attachable insert assembly (30) and a one-piece dumbbell (20) having a female connector (25) and an incorporated spring-loaded pin (28). The insert assembly (30) having a male connector (35) is joined with the female connector of the dumbbell yielding the male connector to be engageable with the spring-loaded pin for fixed attachment. The insert assembly may come in various sizes and in either singular or plural form. Further, the one piece dumbbell and its mating insert assembly may have a cylindrical or substantially cylindrical configuration.</p> |
