When it comes to health and fitness, it's important to understand your body composition and the role that muscle mass plays. Muscle mass is the exact amount of muscle in your body, and it's important for maintaining a healthy weight, burning body fat, and keeping you feeling good. Calculating your muscle mass can be done in a few different ways, including through lean body mass equations, skin fold measurements, or bioelectrical scales. Knowing your muscle mass can help you make informed decisions about your health and fitness goals, whether that's losing weight, building muscle, or maintaining a healthy body composition.
| Characteristics | Values |
|---|---|
| Muscle mass | Skeletal muscle that can be built in the gym, like the biceps, glutes, quads, triceps, and deltoids |
| Lean body mass | Total weight minus weight from body fat |
| Calculating lean body mass | There are multiple equations, including the Boer formula: LBM (men) = 0.407 × weight [kg] + 0.267 × height [cm] - 19.2; LBM (women) = 0.252 × weight [kg] + 0.473 × height [cm] - 48.3 |
| Lean body mass calculation tools | Lean body mass calculator, skin fold calipers, bioelectrical scale |
| Muscle mass and health | Muscle mass is important for health and feeling good throughout the years, as it burns a lot of calories even at rest |
| Muscle mass and diet | Muscle mass ensures the continuous burning of body fat, and a higher muscle mass percentage means a higher metabolism and more calories burned |
| Muscle mass and weight | Muscle mass is heavier than fat mass, so you may have lost fat and gained muscle mass while your weight on the scale remains the same |
| Muscle mass and appearance | Losing muscle can result in an unpleasant appearance |
| Muscle mass and bone mass | Bone mass is the weight of bones and organs relative to total body weight |
| Muscle mass and body water | Body water is the weight of body fluid divided by total body weight |
| Muscle mass and ethnicity | Skeletal muscle mass prediction models need to consider race/ethnicity as independent variables after controlling for weight, height, and age |

What You'll Learn
Calculate body fat percentage
Calculating your body fat percentage can be a useful way to understand your body composition, assess fitness levels, and set health goals. While there are many methods to calculate body fat percentage, most of them require you to gather the following data:
- Age and sex
- Weight
- Height
You will get the most accurate weight measurement in the morning, before breakfast, and without clothes on. To measure your height, stand straight and measure the distance from the floor to the top of your head. Remember to take off your shoes!
With this data, you can use a body fat calculator to estimate your body fat percentage. There are many available online, and some even include charts that show your status at your current weight. You can then plan for a goal weight to put yourself in a desirable, healthy body fat percentage range. Generally, a good body fat percentage range for women is 21 to 35 per cent, and for men, it's 8 to 24 per cent, depending on age. Your resting metabolic rate changes as you age; fat mass increases while muscle mass decreases. Thus, the low end of the range would apply to younger adults and then trend upwards with age.
There are also methods that use body circumference measurements to determine body fat percentage. For example, the US Army and Navy use calculations that require an individual's age, height, and a few circumference measurements. For men, the circumferences of the neck and waist are used in this equation. For women, the circumference of the hips is also included. These methods are easy and affordable, as they only require a flexible measuring tape and calculator. However, they may not be accurate for all people due to differences in body shape and fat distribution.
More accurate methods of measuring body fat percentage include Dual-Energy X-ray Absorptiometry (DEXA), air-displacement plethysmography, hydrostatic weighing, and ADP. However, these methods can be expensive and inconvenient.

Subtract from 100% to get lean body mass
To determine your lean body mass, you can use a simple calculation: subtract your body fat percentage from 100%. This method provides a useful estimate of your overall muscle composition. For example, if your body fat percentage is 20%, then your lean body mass is 80%. This calculation is a quick and easy way to understand the ratio of fat to muscle in your body composition.
While this method is a good starting point for understanding your body composition, it is important to acknowledge that it is a basic calculation and does not provide a detailed analysis of your muscle mass. This calculation gives you an overall picture, but it does not differentiate between various components of lean body mass, such as bone density, muscle mass, and water weight.
For a more comprehensive understanding of your muscle mass, it is beneficial to employ additional methods and tools. One common approach is to use a body composition analyzer, which can provide a more detailed breakdown of your body composition. These analyzers can estimate your muscle mass, bone density, and body fat percentage, giving you a more nuanced understanding of your physical makeup.
Additionally, you can utilize tools such as calipers to measure skinfold thickness at various points on your body. This method helps determine the amount of subcutaneous fat, providing insights into your overall body composition and muscle mass. By combining these tools and calculations, you can gain a more complete understanding of your muscle mass and overall body composition.

Use a lean body mass calculator
Lean body mass (LBM) is a useful metric to understand your body composition and overall health. It is the difference between your total body weight and your weight of body fat. LBM includes the combined mass of bones, muscles, water, ligaments, tendons, and internal organs.
There are several methods to calculate your LBM, some more accurate than others. Here are some common ways to do so:
You can use an online lean body mass calculator, which typically requires your weight and height as inputs. Some calculators may also ask for your body fat percentage or gender to provide more accurate results. These calculators use empirical formulas, such as the Boer formula, to estimate your LBM. While these calculators are easily accessible, keep in mind that they may not provide the most precise results.
Skin Fold Measurement
This method involves using skin fold calipers to pinch and measure the skinfold thickness at various points on your body. The measurements are then converted into your lean body mass using a table or calculator. This technique is relatively easy and consistent but may not be the most accurate. Personal trainers at gyms are often familiar with this method.
Bioelectrical Impedance Analysis
This method uses a special type of scale with electrodes that you stand on or grip with your hands. A gentle electrical current is sent through your body, and since muscle and fat conduct electricity differently, the scale can estimate your lean body mass. While these scales are safe and convenient, factors like hydration levels can affect the accuracy of the readings.
Hydrostatic Weighing
Hydrostatic weighing involves comparing your weight on land to your weight when completely submerged in water. This method is considered very accurate but may not be as accessible as the other methods mentioned.
It is important to remember that these methods provide estimates of your lean body mass, and the most accurate techniques, such as magnetic resonance imaging (MRI), are often expensive and inaccessible. Nonetheless, understanding your LBM can be beneficial for tracking your fitness progress, planning your health goals, and making informed nutrition and training decisions.

Consider skeletal muscle mass
When it comes to muscle mass, it's important to distinguish between skeletal muscle mass and general muscle mass. Skeletal muscle mass refers specifically to the muscles attached to the skeleton that enable voluntary movements. On the other hand, general muscle mass encompasses all muscle tissues in the body, including smooth and cardiac muscles. Skeletal muscle mass is the type that can be actively developed and strengthened through exercise and proper nutrition.
Calculating your skeletal muscle mass can be done through various methods, and it's important to consider individual factors such as age, gender, body size, and fitness level. The most accessible method for most people is to use scales that employ bioelectrical impedance analysis (BIA), which estimates muscle mass based on the body's resistance to electrical signals. More advanced options include MRI scans, dual-energy X-ray absorptiometry (DXA), and computed tomography (CT) scans. These methods provide more accurate measurements but may be less accessible to the general public.
It's worth noting that simply calculating lean body mass, which is your total body weight minus fat mass, does not give a precise indication of skeletal muscle mass. This is because lean body mass includes significant portions of body water and other components like bones and ligaments. Therefore, to specifically target skeletal muscle mass, methods like BIA scales, caliper tests, or advanced imaging scans are necessary.
Additionally, when considering skeletal muscle mass, it's crucial to understand the role of resistance training, adequate protein intake, and overall proper nutrition. Consistent strength training exercises are essential for stimulating muscle growth, and sufficient protein intake helps repair and build muscle tissue. Maintaining optimal skeletal muscle mass contributes to overall health, physical strength, metabolic efficiency, and reduced injury risk.
