Please, read the reviews on Amazon.com before you consider buying this game.  If you still feel so inclined, you might want to rent it first or, at the very least, buy it used.  The responsiveness of this game is terrible!  I won't go into all of the faults of this game because Amazon's reviews really nail it on the head.  There are better programs out there right now, and plenty to come.  Don't waste your money.

I have had this "game" for 4 days now and the whole family just loves it. My 7 yr old twins use it, of course thinking of it as a game....I use it realizing that my heart rate goes way up...and I am burning calories!  Some of the activities are hard to master and with all wii games, it is easy to cheat the game. The monkey bars, for example; when I do them "properly", my character doesn't move...however, when I just wiggle the control and nunchuk...I fly across the bars. So, like everything else....if you put the effort in, you gain the benefits. As for the wii itself, I love it...but, I want to see Nintendo put more virtual reality into it...and make the sensor bar work better
