Abstract
A weight stack assembly for an exercise machine includes: a plurality of weights arranged in a vertical stack; a post extending through the weights, and a selector unit. Each of the weights includes an open-ended, forwardly facing slot, wherein the slots of each of a first set of the weights form a first column, and wherein the slots of each of a second set of the weights form a second column that is parallel to but non-coincident with the first column. The vertical stack is formed by alternating first and second weight. The post is configured to connect with a movement arm of an exercise machine and includes a first column of apertures that align with the slots of the first set of weights and a second column of apertures that align with the second set of weights. The selector unit is configured to be inserted into one of the slots and one of the apertures to select a portion of the weights to provide resistance for exercise.
