Someone has a Wii Fit?
What do you think about make sports with it?
It is a good trainer?

Hmm..Honestly , as someone who works out DAILY I can tell you its only as effective as any dvd would be really. Depending on what you are hoping to acheive with it..it could be fine. I'd say decide on your goals first then see if it suits them. I'd guess its not a substitute for a good gym.
