Your Body Fortress®
BMI Zone


Body Fortress fans know that getting in shape means different things to different people. Still, it’s good to have a baseline standard when setting your goals and tracking results. One such general standard is the Body Mass Index – BMI. There are several ways to measure personal health in relation to body structure and mass composition – body immersion, skin-fold thickness, bioelectrical impedance, isotope dilution – but BMI is the quickest method given that it does not require specialized equipment.

In general, BMI is a measurement based on height and weight that is used to estimate body fat content. However, depending on your body type and physical make-up, your personal BMI result may not mesh with what you see in the mirror. This is because the BMI result table is written for the average healthy adult. But Body Fortress® users are not average; Body Fortress® products represent the pinnacle in sports nutrition, and as such are used by people looking to improve their health, their physique and their performance.



Input your height and weight below, and the Body Fortress® BMI Calculator will return your personal index number.

BMI Scale
The BMI Scale shows you the “body type” range corresponding to your personal index number.

Body Type BMI Index
Underweight < = 18.5
Normal Weight 18.5 - 24.9
Overweight 25 - 29.9
Obese > = 30

Remember – BMI numbers are representative of the average person and are meant as an estimate of body fat content. However, “non”-average body types will sometimes get results that sound odd by definition. For instance, a well-toned athlete who has used Body Fortress® products to help them shape lean muscle might actually yield a BMI result of “overweight” because their muscle mass is denser than average. And, those who have used Body Fortress® products to pack on muscle mass may actually come out as “obese” because their muscle to height ratio is well beyond average.

BMI Chart
A second way to view BMI results is across a range, as shown here on the BMI Chart. This chart presents a way for Body Fortress® users to set their personal goals and to track their progress in terms of height to weight ratio. Again, remember – different body types will yield different results. Ultimately, how you feel, what you see in the mirror and what your trainer and/or doctor says is the best indicator of personal progress, especially when you are looking to go beyond the average and into the Body Fortress® Zone!
