Accordingly, individuals with BMI< 18.5 are classified as slim or underweight and people with BMI between 18.5 -24.9 are called normal body types. Subsequently, those individuals with BMI between 25-29.9 are categorized as overweight and people with BMI > 30 are classified as obese people. Nonetheless, important question is where the muscular individuals are located in this BMI scale ? Macular induvial also called overweight or obese in BMI scale which can create kind of confusion for individuals because they might try to lose weight whilst they do not actually need it. Thus ,it seems BMI measure is not a sensible measure for muscular individuals as otherwise they can be at risk of health problems in various ways. Uses of the another apparatus such an ordinary weight scale or computational devices which could estimate the body type according to the BMI more accurately can be helpful.
