I used my wifes a couple of times and it didn't seem to be that good. The weights are no where near what they claim. They are alot less weight. I used a bowflex also and ended up loosing weight when I was trying to bulk. I went out and spent $100.00 bucks on plates and 2 hand bars. Works pretty good for days I can't get out.
