Lean body mass is increasingly recognized as a critical statistic of human fitness. More so than body weight or BMI, lean mass informs about the composition of the body (fat & non-fat fractions). The best estimate of lean mass comes from calculation of the density of the body which is easily and accurately measured by means of “underwater weighing” (AKA hydrostatic weighing, hydrostatic fat testing). This gives a valid & reliable body fat percent.
