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!!

I always find the recumbent as being a better bike it more conformable and it has more support for your back and your alot more stable on it so think number 2 might be the better choice!

First of all, you need to know that exercising while watching T.V. isn't appropriate as you don't focus enough on the muscles and therefore you are more prone to accidents, bad posture, and the exercises are not as effective. I would suggest swimming, not only it helps reducing the appearance of cellulite, but it also works your cardio and muscles without putting strain on your joints, and it will help you work out all your muscles, especially is your alternate free-style, back stroke, and breaststroke.
