Abstract
An exercise device has a pair of handle portions that are connected by a pair of connection portions to form an annular body. The pair of connection portions have a flattened cross-section that provides a rotation bias towards a rest configuration. The rotational bias of the pair of connection portions enables a twisting exercise that is useful for strengthening the hands and forearms of a user.
