A BMI between 18.5 and 24.9 is considered normal for men. However, many healthy, athletic men fall in the 25-27 range due to higher muscle mass. Consider body fat percentage alongside BMI for a more complete picture.

BMI only measures weight relative to height and cannot differentiate muscle from fat. Since muscle is denser than fat, men who strength train or have naturally high muscle mass may be classified as overweight by BMI despite having healthy body fat levels.

BMI Prime is your BMI divided by 25 (the upper limit of normal). A value under 1.0 means you are within normal range. It provides a quick ratio that shows how far above or below the healthy threshold you are.
