An apparatus for weight training is attached to a weightlifting device, such as a barbell or a selectorized weightlifting device. A second weight to be lifted is then coupled to the apparatus. The apparatus is adjusted for the varying skeletal configurations of various individual users. Within one portion of the exercise stroke of the invention, the resistance to lifting continuously varies between that of the weight lifting device and the sum of the weightlifting device and second weight. Thus, the effect of the lifting stroke is increased for each exercise stroke.
