Structural conduits and fittings are interconnected to form a stand having long, horizontal feet that extend close alongside opposite sides of a standard step aerobics exercise step. Upright legs of the stand have lower portions angled upward and outward from the feet, leading to upper vertical portions or columns that are offset outward from the opposite sides of the step. A horizontal hand bar used for balance is supported by the columns and can be adjusted up or down to accommodate users of different heights. The feet of the device can be swivelled so as to lie substantially in the same plane as the top bar and legs.
