A modular upright for an exercise equipment superstructure has a base with a floor plate and a stub, a lower tubular upright portion, a connector and an upper tubular upright portion. The lower tubular upright portion and the upper tubular upright portion both have openings defined at regular intervals along their length for supporting exercise equipment accessories, as well as correspondingly positioned openings in the stub and the connector so fasteners can be used for connection of the components. The stub, the upright portions and the connector are all formed of tubing, sized so none of the columnar load stresses the connector or the stub or the fasteners.
