This game focuses squarely on boxing. There are no other cardio elements to it. Even the floor routines are designed for boxers only. The game is not properly responsive to the wii controls. It is annoying to have to play through the simpler routines to unlock others. I'm here to exercise...why are you denying me access to a full suite of a workout? I really hate "wii fit age". It has no bearing on the actual successful completion of an exercise, especially if the game is unresponsive to the wii controls.
