Stamina Intone Folding

Which piece of exercise equipment is better?

I am not really interested in loosing weight, per say, but I'd like to slim down. I know I'd build lean muscle and burn fat, and I'm just looking for a machine to help me do that. I do go on the treadmill a couple times a week, but it's absolutely BORING. I'd like a compact exercise system that I can put in front of my T.V. and just exercise while watching TV or something!

I'm wondering how effective exercise bikes are. I found two that seem to get good reviews. One is an upright bike, and one is a recumbent. They both look comfortable to me, so I'm not concerned about which one is more comfortable.

Which one would be better for my desires? Neither? Please post some suggestions. Thanks!

exercise bikes are very effective if you want 2 slim down.
a recumbent is a better bike b/c it has back support and its more fun than the upright ones.
i use on and it works well if you use it i guarantee you'll reach your goal!!
