Abstract
Abstract A portable exerciser includes a rotatable platform on which a person desiring exercise can walk or run and adjustable height handholds which the person exercising can grasp to maintain balance. Auxiliary legs are provided permitting the surface of the exerciser to be tilted in simulation of a hill and an adjustable brake controls the amount of resistance to motion for varying the exercise content of the activity. The walking or running surface may be folded or rotated into alignment with the posts supporting the handholds for compactness of storage and transportation.
