Nike + training is really a very well designed game for kinect. The movements are generally well ... except may be currently detected during ground movements, for which it is necessary to move a little kinect. Quality of exercises, these are tailored to the objectives that we give (toning, slimming, ...) and are of a very high level. So it is better for people who play sports only occasionally adopt a flexible weekly basis (2-3 times per week during the first weeks). Otherwise, it's true that this is very exhausting at first, but it gets to like it later! -D In any case, for those who want to play sports at their own pace and at a price much lower than that propose gyms, this is the game for you (regardless of your sporting level for that matter)! !
