Get a good elliptical. It will work out your entire body (unlike stationary bikes) and not hurt in case you have knee problems (like treadmills). Put the elliptical in front of TV if you like and do 30-45mins every other day. I was 193lbs in August. I'm 174lbs now. Though I'd say I'm more of an exception because I gain/lose weight really fast. Nevertheless, I highly recommend a good elliptical - both my wife and I love the one we got.
