From wii.ign.com:

There is no doubt that any Wii owner interested in My Fitness Coach will immediately compare it to Wii Fit. Both are great exercise games, but they take two very different approaches. Where Wii Fit gave off a casual workout vibe (a sweat inducing vibe nonetheless), My Fitness Coach comes at you more like an aerobics DVD.

Let’s get one item out of the way up front. My Fitness Coach does not use the Wii Balance Board. The Balance Board works wonders for its pioneer outing, but it’s still a more casual approach overall. Trust me though, even without the Balance Board, My Fitness Coach will give you one heck of a workout.

My Fitness Coach starts out with a fitness analysis to determine the level of shape you are in. You will be asked to enter expected information such as you name, gender, weight, height, and date of birth; but things get even more technical from here.
