I would like to get some comments on the effectiveness of Rowers for MX. Does anybody out there own one? I found a Schwinn (wind resistance type) rowing machine a a play it again sports for 300$. It's a used model (I've seen them new for over 700$) and I think it's a pretty good deal. I don't think that Schwinn makes rowers anymore and I'm not sure if I will be able to get any parts for this thing or not. The sales guy that works there is trying to find out if parts are available threw some other source. Any comments are appreciated. Thanks This exercise bike just doesn't seem to help that much. I still have a hard time getting threw 4 laps without feeling like I'm about to have a heart attack.
