Exercise devices of the type designed for running on the spot include balls or rollers mounted in a frame. A more interesting apparatus of this type includes a plurality of balls independently rotatable in a recess on an inclined base and a source of electrical current connected to the base for feeding current to the balls for stimulating the feet of the user. The current to the balls is controlled by rotating the handle attached to a post mounted on one end of the base. A belt carrying electrodes for stimulation of the lower back and separate electrodes for stimulation of the trapezius in the upper back can also be connected to the post.
