Abstract:
1. A dumbbell, comprising: a grip configured and sized for grasping by having a flattened cross section that provides a major axis and a minor axis when viewed in cross-section, thus enabling torque transmission through the grip; and at least two weight portions having first ends provided at opposite ends of the grip, the two weight portions having a second major axis and projecting from the grip in parallel along the second major axis and together with the grip defining a substantially U-shape, second ends of the weight portions distal to the grip having an open space therebetween such that a user's hand can freely pass directly between the second ends; wherein the grip is directly connected to each of the weight portions at an off-center position deviating from a center-of-gravity portion of each of the weight portions, and, when viewed from an end of the grip looking in a longitudinal direction of the grip, an angle between a direction from the off-center position toward the center-of-gravity portion along the second major axis of the two weight portions and a direction parallel to the major axis of the grip is between 20° and 80°.
