Let's start with BMI.

The Body Mass Index ("Body-Mass Index" or BMI) helps test whether a person's weight is healthy for his or her height. If a person weighs less or more than the recommended weight for his or her height, he or she may have health problems in the future. Although BMI is not the only factor to consider when working on one's health and fitness, it is a good starting point. To find out what your BMI is, enter your information below.
