摘要:
A dumbbell system a plurality of weights vertically stackable on top of each other and each of the weights has a pair of outer edges disposed oppositely from each other to define a first lateral edge and a second lateral edge. The weights each have a centrally displaced opening vertically extending therethrough and defining a receiving space. The receiving space of each weight is vertically aligned with the receiving space of each of the other weights. A handle is removably extendable into the receiving space. A coupler releasably engages a selected one of the weights to the handle and defines a coupled weight. The coupled weight and each of the weights positioned above the coupled weight is releasably secured to the handle. Each of the weights positioned below the coupled weight are disengaged from the handle.
