Hey I'm curious, how does Move Fitness track your torso? For example I'm playing Kinect Fitness Evolved 2012 now and it tracks all my movements so it knows when my feet aren't far enough apart, if my squat isn't deep enough, arms too high, not punching far enough forward, etc, and the lady scolds me accordingly during the routine to correct my movements, and you get a rank at the end of how close I was to her movements. How does that all work on Move Fitness, or does it just track your hands where the Move glowing globes are and just mixes that with cardio routines?
Move Fitness has a full skeleton behind it with some cleverness that derives your whole body position from the position of the two Move controllers. It is an evolution of the technology in The Fight, which also supported head-tracking, but Move Fitness no longer uses that I think. You can pretty accurately move around and many games actually require you to run to the left and right to catch or hit stuff, as well as duck, stretch, weave, etc. Combined with a pretty good and very fast calibration routine (stretch out your arms and press the Move button), that works pretty well.
Obviously though, it won't be able to tell you if your feet aren't far enough apart. However, this is imho well compensated by the insanely accurate tracking of your hands (any wrist movement is accurately reflected) and the fact that many of the exercises are actually a lot of fun. You can target most of the body with Move Fitness, but there is no denying that because the tracking is most accurate in the hands/arms and the most fun exercises involve doing stuff with your hands (as well as your whole body) my personal stats skew towards upper body training (as well as cardio obviously). This is good for me personally, because my main out-door exercise is cycling.
However, it should be clear that stuff like Kinect Fitness and Your Shape 2, taken purely as a complete fitness replacement, are likely to be superior, just for being able to track your full body. But personally I think Move Fitness is a fantastic title.
I think the best choice in this case may be a personality thing as well as what kind of exercises you are looking for, as well as how much space you have available. Imho, Move Fitness is one of the most fun fitness titles out there that is rewarding in the long term by sheer virtue of you getting better at the 'games', good friends list integration, challenges etc. But it still also allows you to select from various routines that target specific areas of your body, and quite extensive options for creating your own routines as well. The user interface is also really pleasant.
(I have some videos of the game on my website, as I think I've already posted here before I won't repost them, but if you want them let me know or find them at Arwin14 on youtube).
