Quoting Movemodo's Patrick Elliot:
"The daily workouts the game creates impress not only due to their intensity and variety, but also because they are tailored to your body type and preferences. They are definitely going to make you sweat too, and you can expect to be sore. But that's a good thing – the game would be garbage if it didn't do that. Just don't trust its meal plans too much, as they are better used as an awesome recipe book. What keeps the title from being great is its failure to keep up with the user, and if you fire up to double-time it is not going to pick it up. What's worse is that it sometimes gets confused and misinterprets your zealous movements as a poor performance, earning you a bad score for giving it your all. Still, this only happens sometimes, and doesn't deter from the fact that you are getting a great workout."
