Discover your Body Mass Index and what it means for your health. With honest context about the limitations of BMI if you train.
Important nuance: BMI does not take muscle mass into account. If you train regularly and build muscle, your BMI may seem "too high" while your body fat percentage is fine. Body fat percentage is a better measure of body composition than BMI alone.

Message SteevBMI (Body Mass Index) is a simple ratio between weight and height. It gives a rough indication of your weight category, but says nothing about your body composition. Two people with the same BMI can have a completely different body fat percentage and fitness level.
For athletes and people who do regular strength training, BMI is often misleading. Muscle mass weighs more than fat, so a trained person quickly falls into the "overweight" category while the body fat percentage is actually low. Use BMI as a starting point, not as a final judgment.
