George, I have been working out on the exercise machines for about 6 months now and I think it has reduced the muscle sorenes and the ridigity in my fingers, which were due to the tremor I have in my left arm and fingers. I pull down on the bar that then lifts the weights, by holding on with my fingers only! Lanier Maddux Chattanooga Tn. (plmaddux@webtv,net)
