It's a bit confusing, the advert is too flashy. Looks like you can't push very much weight on it so the benefits may not be huge. Better to use the full range of machines and weights at a communal gym.
Check out Jeff Cavalier. I'm a PT and I love his stuff. He has multiple programs and plenty of advice videos on YouTube. Best thing is it's web based so it's much less expensive and you don't do the same DVD over and over. Worst thing is he talks too much.
