A collapsible resistance exercise device for compact storage and quick deployment includes a horizontally disposed base support frame and an upright frame pivotally attached to the base frame. The upright frame includes a resistance bar pivotally mounted thereon. In practice, the device is placed on a level surface with the base support frame resting on the surface. The free end of the upright frame is rotated upwardly to a vertical position where it is releasably locked into position to be free standing. One end of a pair of springs are attached to spring attachment loops disposed on the upright frame. The opposing ends of the springs are attached to spring attachment loops disposed on a resistance bar, strap or similar device. The exerciser exercises a muscle group by contacting a limb with the resistance bar and repetitively moving the resistance bar against the restoring force of the springs.
