Training is at the core of Wii Fit. You can spend as much (or as little) time as you want trying out all of the 40+ activities Wii Fit offers. Each game is designed to help you work your way to a more fit you. Depending on your preference, you can get a structured workout with an in-game personal trainer in Yoga or Strength Training, or for something faster paced and less structured you can try your hand at the Aerobics or Balance Games.
As you progress in training, it's only natural you'll get better at the Wii Fit activities. When you reach certain benchmarks in training, new levels of difficulty will become available, increasing the number of options you have for your workout. Continuous training will also lead to receiving new tips on how to combine trainings. One example is combining the Warrior pose from Yoga with the Lunge from Strength Training. Who knows what else you'll unlock?
How did you do?
After every activity, you'll receive a star rating indicating how you performed along with your results. This is then compared to the other users who play Wii Fit, so you can see how the rest of your friends and family scored compared to you. If you are not satisfied with the rating you achieve, you can try as many times as you'd like to improve your score.
