Summary: I was really hoping this game was going to be like the EA Sports Active but as my title states it's sadly lacking. The good: The exercises can be challenging. You can work up a sweat on a few. The bad: The use of the eye is pointless and the exercises can be done without it. The only tracking of your progress it does is this weird chart divided into categories like strength or flexibility (depending on what your goal is). It'll tell you how much of that goal you hit.
Summary: The workouts are not that interesting. For most the workouts, I don't feel challenged. I don't like that you have to purchase all the "good" workouts. Not upset with this product, I just dont think it's for me. For some people, this may be everything you've ever wanted. In all fairness though, even Just Dance games can get boring and repetitive, and you even have to purchase more songs from them to have more choices.
Summary: The best feature is being able to know in advanced how long each set will go and how intense it will be. The warm-ups are also very good and use your whole body. Both of these are far better in Fit in Six than Your Shape Fitness for XBox. The only significant problem is the audio. The narrator/trainer is misused. The verbal cues are poorly implemented/timed so you can miss changes and/or have to rush to get into the next position.
Summary: If you're looking for a true PS Move game that tracks your progress with the controller this isn't the game for you. If you're looking for a workout video that allows you to use the move camera and see yourself then this the perfect game for you. Basically this game is a high tech workout video that doesn't even utilize the controller. I will say that the workouts are worthwhile but I was expecting something that would more accurately track my progress.
Summary: It is possible with Fit in Six to get a good workout. There are a variety of cardio options. Workouts tend to be shorter. I think the maximum I have found is about 35 minutes. I mix and match when I want a long workout. I haven't made good use of strength/toning yet as I am following another program, so I can't really comment. The couple I have tried have been effective and I like some "new to me" exercises.
