I am sure its a great machine but what about cardiovascular training? Last 8 years I decided to skip the weights and only do cardiovascular activities like bicycling, running, swimming, and elliptical machine. I do not have bulky muscles but my weight control is good, I have great stamina and supposedly those who keep up the cardio program live longer. I did dead lifting in high school, I seem to recall putting 300 lbs over my head as a personal best at the time.
