You have the option of taking a fitness test which includes stamina, power, and speed. Because of the default settings, you can only take the test once a day and must wait until the next day before retaking it. Use the following trick to take the test as many times as desired a day. Go into the Wii system settings and select the calendar option. Then, just move the date up by one day. The game will think a day has passed and allow you to retake the test.
