A portable exercise device for performing Pilates-type exercises includes a base portion having first and second base members interconnected through a pivot member. In a first configuration, a first end portion of a bar is selectively connected to the pivot element while a second end portions of the bar is connected to the first and second base members by elastomeric bands. In a second configuration, first and second end portions of the bar are connected to corresponding ones of the first and second base members by elastomeric bands. When in the first configuration, a user selectively shifts the bar side-to-side about the pivot member to alternatingly stretch and relax the elastomeric bands. When in the second configuration, the user selectively manipulates the bar to simultaneously stretch and relax the first and second elastomeric bands through mainly vertical movements.
