A barbell includes a substantially tubular-shaped barbell bar enclosing a device for causing the barbell bar to vibrate, weights attached to each end of the barbell bar and a damping material interposed between the barbell bar and the weights. The damping material prevents the weights from being subject to the vibrations. As a result, vibrations are transmitted to the muscles used for lowering and raising the barbell bar thereby reducing the time expended to train and the tendency to develop a cramp. Furthermore, because the weights are disconnected from the vibrations, the stability of the barbell weight and training arm is not disturbed and the energy consumption of the motor remains low.
