Sharon, don't let some of the negative comments get under your skin. The people who are grossly overweight and the same type of people who love to complain all the time. They don't spend evergy on excercise they spend it eating bad food, watching tv and complaining (especially about people who are successful at what they do, like yourself) So, keep up the good work. Don't let the these people get you down. If they know of better ways to excericise, why don't they go out and do it, rather than complain. thanks, bob
