Abstract: A portable upper body exerciser which is compatible with walking or using a treadmill permits vigorous upper body exercise involving hands, arms, biceps, triceps, shoulders, and neck. The upper body exerciser is a harness that rests on the shoulders and/or mid back and waist of a person with a forward extension member presenting handgrips at the distal ends of a hand crank that can be rotated much as bicycle pedals are rotated by the feet. The hand crank is positionably movable and attachable anywhere along the outer surface of the forward extension member, for the convenience of the person using the portable upper body exerciser.

Abstract: An upper body exerciser which is compatible with walking or using a treadmill permits vigorous upper body exercise involving hands, arms, biceps, triceps, shoulders, and neck. The upper body exerciser is a harness that rests on the shoulders of a person with a forward extension presenting handgrips at the distal ends of a hand crank that can be rotated such as bicycle pedals are rotated by the feet. Since the harness is easily donned or removed with just a single motion without the need for confining straps, its convenience encourages frequent use.
