Bowflex
I have owned a Bowflex for a few years now and I think it is a good product. It is well made and very effective. In High School and College I was a competition power lifter. Now that I am older I wanted some form of resistance training but didn't want to have a pile of iron weights in my house.
The bowflex provides smooth and fluid resistance training that is deceptive since to does not seem like you are doing anything at all until the next day when you will be feeling it. I have never hurt myself using free weights however with the bowflex my self driving nature has caused me to over load myself and I have been injured as a result.
It isn't perfect but overall I like mine a lot.
