An ‘old army body fat calculator male’ is a formula used to determine body fat percentage in men, developed by the U.S. Army in the 1980s. It uses measurements of the neck, waist, and hip to estimate body fat.
This calculator is widely used in the military and fitness industry and has been shown to be a reliable and accurate method for estimating body fat percentage. It is particularly beneficial for assessing body fat in men who have a large amount of muscle mass, as traditional methods, such as underwater weighing or skinfold measurements, may not be as accurate.
