Wii Fit- Does it Count as a Workout?

I got Wii Fit for Valentine's Day and as I began playing, it wasn't what I thought it would be. People that have plaed it claim to be sore, they sweat, and they feel a workout. Me, on the other hand, feel nothing.

Based on reviews of the Wii Fit, many people simply like the fact that you are involved in the game. Instead of just sitting in a seat pushing buttons, you at least have to stand and move around a bit. I am most looking forward to unlocking more yoga poses. I guess eventually I can make it into a full flow.
