A hand held exercise device for providing a user with a portable workout. The device may generally comprise a central handle diametrically disposed within and spanning across a ring element having a toroidally shaped inner chamber. Internal bumpers within the inner chamber act to limit the range of motion or travel of at least one mobile element within the inner chamber. Rotational forces imparted by the user upon the handle cause movement of the at least one mobile element that is responded to and countered with user muscle flexion. In this manner, a user may perform a satisfactory workout by continually imparting and then resisting rotation force in alternating clockwise and counterclockwise directions.
