Instructions
Select your profile from the Wii Fit Plaza. Choose "Body Test."
Power on the Wii balance board. Wait for the board to connect to the console, then step on the board when the game asks you to.
Choose the weight of your clothing -- "Light" for 2 lbs., "Heavy" for 4 lbs. and "Other" for no weight.
Stand still, in a relaxed posture and with your weight evenly distributed to both feet, as the game measures your weight.
Press the "Weight" button on the BMI results page to see your current weight, minus the weight of the clothing you selected.
