Knowing your body fat percentage is critical when trying to improve your body composition. For example, if you have 50 pounds in fat and 150 pounds in lean body weight, then your total body weight is 200 pounds. If you lose 2 pounds in fat and gain 3 pounds in muscle, now you weigh 201 pounds. By using a regular scale, you might think you gained fat. But with Body Tracker calculator you will know you lost fat and gained muscle. Tracking body fat is the best way to improve your body composition.
