I bought turbo jam last year, and I had great results, but then I went off the wagon because I work 12hr nights and that makes me so tired all the time. I gained all my weight back and more. I just started back on it a few weeks ago and although I haven't lost more than 3lbs my clothes are bigger so I know its starting to work. I have my daughters wedding to go to in sept so I am very motivated. I don't feel as tired and turbo jam is the only one that I don't get bored with. When I feel too tired I just do the 20min workout and that keeps me going, and that is why I have been keeping up on it(besides the wedding). It really does work, it is fun, and you will see a difference if you keep it up and watch what you eat.
