Abstract
A combination twister and stepper device includes a stepper unit and a twister unit in combination with a common frame. The stepper unit has a pair of side by side steps, each of which is biased upwardly. The twister includes a turntable or disk on a pivotal mount. The stepper and twister are secured to a frame which includes a pair of pivotal poles. The stepper and twister may be used simultaneously while also using the poles or the stepper and twister may be selectively inactivated so that only one of the units is used.
