Your desire to have a fit, trim, and a lean body ends here! Wondering about your lean body mass and body composition? Use our Lean Body Mass Calculator to find out and receive essential tips for improving your fitness.
Calculate your lean body mass to determine the weight on your body that isn’t fat. The key objective for fitness enthusiasts is to reduce weight while maintaining their lean body mass. Increasing your leans while reducing your fats is the key to looking great. Working out and improving your fitness is crucial to building muscle and our Lean Body Mass Calculator is your best guide in this regard.
Lean body mass does not inevitably indicate a fat-free mass. Lean body mass contains roughly 3% of fat within the central nervous system which constitutes the brain and spinal cord, marrow of bones, and internal organs. It is measured in terms of density.
The Lean Body Mass can be calculated using three different formulas as set forth below to find the lean body mass.
Boer Formula:
Male : (0.407 * weight in kg) + (0.267 * height in cm) – 19.2
Female : (0.252 * weight in kg) + (0.473 * height in cm) – 48.3
The Lean Body Mass for males can be calculated by height in centimeters multiplied by 0.267, then adding the weight in kilograms multiplied by 0.407, and finally subtracting 19.2 to get the result.
For females, the Lean Body Mass can be found by multiplying the height in centimeters by 0.473, the weight in kilograms by 0.252, and then subtracting 48.3 from the total.
James Formula:
Male : (1.1 * weight in kg) – 128 * (weight in kg / height in cm)2
Female : (1.07 * weight in kg) – 148 * (weight in kg / height in cm)2
The James Method is a formula used to calculate Lean Body Mass for males, involving multiplying weight in kilograms by 1.1 and then subtracting 128 from the result to find the first component. Simultaneously, dividing weight in kilograms by height in centimeters produces a quotient that is squared to get the second component. The Lean Body Mass for males is obtained by multiplying these two components.
For females, their Lean Body Mass is determined by multiplying their weight in kilograms by 1.07 and then subtracting 148 from the result to get the initial component. Additionally, dividing weight in kilograms by height in centimeters and squaring the resulting quotient derives the second component. The Lean Body Mass for females is then calculated by multiplying these two components.
.Hume Formula:
Male : (0.32810 * weight in kg) + (0.33929 * height in cm) – 29.5336
Female : (0.29569 * weight in kg) + (0.41813 * height in cm) – 43.2933
The Hume Formula offers a refined approach to estimating Lean Body Mass (LBM) by incorporating gender-specific calculations. For men, this formula combines their weight in kilograms multiplied by 0.32810 with their height in centimeters multiplied by 0.33929, and then subtracts 29.5336. This method provides a tailored estimate of lean body mass, reflecting the proportion of muscle and bone without the influence of body fat. For women, the formula adjusts the coefficients: weight in kilograms is multiplied by 0.29569 and height in centimeters by 0.41813, with a subtraction of 43.2933 from the total.
Utilizing the Hume Formula enables more precise body composition assessments by considering these gender-specific factors. This personalized approach not only supports effective fitness and nutrition planning but also enhances overall health monitoring by providing a clear picture of lean muscle mass versus fat. Whether for optimizing workouts or tracking health improvements, the Hume Formula delivers accurate insights tailored to individual needs.
