Bests & Worsts Reviews from Amazon

I was ready to be very skeptical of the Kinect and motion tracking in general (concerned about lag and accuracy). After playing this for 45 minutes this morning, I was very happy with it. I have used EA Sports Active and More Workouts on the Wii for the past year and have gotten in much better shape with it, but having to hold the controllers and the leg strap gets in the way for me. I was hoping that with this I would be able to consign the controllers to the dust bin of history and so far so good! I did the initial training, some of the toning exercises, and the first Zen class and can report that everything worked beautifully. And it kicked my butt today, so the intensity is definitely there. I like the feedback given by the motion detection - much more immediate and accurate than the Wii controllers seemed to be. As you move you see your image on screen moving and if there is any lag I don't see it. Doing the lunges for instance, it told me I was getting out of rhythm and was not doing the lunges completely. Using the onscreen trainer and my feedback I was able to correct quickly and see that if I dropped my knees a little bit more the onscreen trainer was happy with what I was doing. I haven't gone very deep into the program, as I said before, but the range of exercises and number of different programs seems to put it will ahead of the Wii games I have played, and I have to admit I was getting VERY bored with the other programs, so also very glad to have something different to use.
