Body Mass Index(BMI) Calculator

Body mass index (BMI) is used to assess total body fat based on your height and weight. While research has shown that BMI is a reliable indicator of body fat, there are some limitations. If a person is very muscular, BMI will overestimate the person’s body fat and the person may fall into the overweight or obese category. If a person is older, or has lost a lot of muscle mass, BMI may underestimate body fat and the person may not appear to be at any risk when actually they might be.

BMI should be used in conjunction with other assessment tools to thoroughly evaluate your fitness level.
