ABSTRACT:
A free weight unit with a spinning mass element, which comprises a casing for accommodating the spinning mass element in a rotatable manner about a rotation axis, and also accommodating an electric motor for rotationally driving the mass element and a battery for the electric motor. This free weight unit is designed to be used effectively for training, rehabilitating or physical exercising of the human body, and the-casing generally has a relatively large dimension sufficient to accommodate a relatively large mass element, which may be difficult to be gripped directly by hand. In this free weight unit, a certain vector of the precessional output torque is generated due to an input torque applied to the spinning mass element rotating about the rotation axis, by operating a selected one of the two elongated sections of the shiftable member to turn about a certain input axis extending in a direction different from a direction of the rotation axis.
