Each weight includes two spaced plates joined in a rigid manner by at least one interconnecting member. The weights can be nested together in a horizontal weight stack such that a connecting pin inserted through the weight stack can select one or more weights for use as the exercise mass. In one embodiment, the interconnecting member is a channel having overlying front and back walls. A plurality of sets of aligned holes and slots are placed in these walls with each set having a uniquely different hole and slot arrangement. The pin can be inserted through any one set of holes and slots to couple a desired number of weights together for use.
