Abstract
A supplemental weight stack is disclosed. The supplemental weights add a weight load to an exercise machine in increments less than the main weight increments. The supplemental weights can be stacked horizontally and can be designed such that when engaged, each supplemental weight acts upon an engagement mechanism. The user selects the supplemental weight by acting upon an adjustment mechanism, which, in turn, actuates the engagement mechanism.
