What You'll Learn
Lean body mass
The percentage of LBM is usually not computed, but it on average ranges between 60-90% of total body weight. Generally, men have a higher proportion of LBM than women. The dosages of some anesthetic agents, particularly water-soluble drugs, are routinely based on the LBM. Some medical exams also use the LBM values. For body fitness and routine daily life, people normally care more about body fat percentage than LBM.
There are several ways to calculate LBM, some include using mathematical formulas, while others involve advanced technologies like dual-energy x-ray absorptiometry (DEXA). The Boer formula, for example, calculates LBM differently for males and females, taking both weight (in kilograms) and height (in centimeters) into account. For men, the equation is LBM = (0.407 * weight) + (0.267 * height) - 19.2, while for women, it is LBM = (0.252 * weight) + (0.473 * height) - 48.3.
It is important to know your lean body mass if you are trying to lose weight or build muscle. Once an individual has their lean body mass, body fat percentage, and total body weight determined, they can utilize this information to create personalized exercise and nutrition plans. For instance, calculating resting and active metabolic rate can help design a diet plan that achieves the desired caloric intake to lose fat or build muscle efficiently.

Muscle mass and health
Muscle mass refers to the weight and size of the smooth muscle tissue in the body. It includes skeletal, smooth, and cardiac muscles. Skeletal muscle, which helps control physical movement and posture, is the most commonly referred to type of muscle mass.
Muscle mass is an important indicator of health. Higher levels of muscle mass are linked to a longer life. A 2023 study showed that low muscle mass was associated with higher mortality risk from all causes, including cardiovascular disease, cancer, and respiratory disease. As people age, they experience anabolic impairments in skeletal muscle, leading to reductions in muscle mass and strength, which are directly associated with higher mortality rates in the elderly. This reduction in muscle mass is called sarcopenia and can make everyday activities like walking or climbing stairs more difficult. Sarcopenia is also linked to physical disability, poor quality of life, and death.
To maintain muscle mass, it is important to engage in strength training and eat a nutrient-dense, balanced diet. Strength training, also known as resistance or weight training, forces the muscles to work against resistance, which helps build and repair muscle. Protein is particularly important for building and repairing muscle. As people age, it becomes even more important to maintain muscle mass to preserve mobility, boost bone health, and promote healthy aging.
While there are no specific guidelines for what a healthy muscle mass percentage should be, it is beneficial to have a higher percentage of muscle mass as it is associated with a lower percentage of body fat, improved cardiovascular fitness, and reduced risk of injury. Additionally, forms of exercise that build muscle can increase bone density and provide mental health benefits, such as improving symptoms of depression.

Calculating muscle mass
It is challenging to precisely calculate muscle mass without specialised equipment, and it is currently impossible to determine one's exact muscle mass percentage without expensive technology. However, there are a few ways to estimate muscle mass percentage.
One way is to calculate body fat percentage and subtract this number from 100. This can be done using a body fat scale, which calculates the amount of fat by sending an electrical current through the body. The United States Navy recommends another method, which involves measuring the circumferences of various body parts. Different values and heights represent various body fat percentages.
Another way to estimate muscle mass is to calculate lean body mass (LBM). LBM is a part of body composition that is defined as the difference between total body weight and body fat weight. This means that it counts the mass of all organs except body fat, including bones, muscles, blood, skin, and everything else. While the percentage of LBM is usually not computed, it on average ranges between 60-90% of total body weight. There are multiple formulas for calculating LBM, and it is possible to do so using an online calculator.
It is important to note that the percentage of muscle mass varies between people and depends on several factors, including fitness, body size, and gender. Additionally, maintaining a higher muscle mass has several benefits, such as reducing the risk of age-related muscle loss and reducing the risk of injury. Strength training and eating a nutrient-dense, balanced diet are effective ways to build and maintain muscle mass.

Building muscle mass
It is challenging to accurately determine muscle mass percentage without advanced technology. The human body is composed of two components: body fat and lean body mass. Lean body mass includes muscle mass, bone, skin, water, and organ mass.
In addition to strength training, nutrition plays a crucial role in building muscle mass. Consuming a nutrient-dense, balanced diet, including adequate protein, is essential. Protein helps build and repair muscles, and its required amount depends on the level of physical activity. Eating small servings of protein-rich foods before and after resistance training can promote muscle growth. It is important to note that gaining muscle mass often leads to increased body fat as well.
For those seeking to build muscle mass, it is advisable to consult professionals such as a doctor, gym instructor, personal trainer, exercise physiologist, or physiotherapist. They can provide guidance on exercise techniques and help design personalized programs suited to individual needs and capabilities.

Maintaining muscle mass
Strength Training
Also known as resistance or weight training, this type of exercise strengthens your muscles by forcing them to work against resistance. This can be done through weight-bearing exercises such as power yoga, push-ups, and squats, or with the use of resistance bands or weights. The Physical Activity Guidelines for Americans recommend that adults do at least two strength training sessions each week that target all the major muscle groups.
Progressive Resistance Training (PRT)
PRT is a specific type of strength training that involves gradually increasing the resistance over time, providing a constant challenge to the body and preventing plateaus. This type of training has been shown to be effective in increasing lean body mass in older men.
Diet
Eating a nutrient-dense, balanced diet is key to maintaining muscle mass. Good nutrition can help fuel your body and repair muscle after exercise. Protein, which helps build and repair muscle, is particularly important. The amount of protein you need depends on your level of physical activity, but it is recommended that older adults who do resistance training consume a daily intake of 1 to 1.3 grams (g) of protein per kilogram of body weight. Animal sources such as meat, eggs, and milk are considered the best sources of protein, as they provide the proper ratios of all the essential amino acids. However, it is important to avoid red and processed meat due to their high levels of saturated fat and additives.
Timing of Meals
To maximize muscle growth and improve recovery, it is suggested to consume a drink or meal with a carbohydrate-to-protein ratio of about three-to-one or four-to-one within 30 minutes after your workout. For example, chocolate milk, which has about 22 grams of carbs and 8 grams of protein, is a good choice.
Start Slowly and Gradually Increase Intensity
When beginning a new exercise routine, it is important to start slowly and gradually increase the intensity to avoid injury and over-exertion. Focus on your form and add more weight or intensity over time as your body adapts to the new routine.
By incorporating strength training, PRT, and a balanced diet with adequate protein, you can effectively maintain muscle mass as you age and improve your overall quality of life.

Frequently asked questions
There are a few ways to measure muscle mass percentage. Imaging tests, such as DEXA scans, are considered the "gold standard" for measuring muscle mass. Other methods include skin-fold calipers, underwater weighing, and smart scales.
Knowing your muscle mass percentage can help you understand your overall body composition and health. Higher muscle mass increases metabolic rate, prevents falls, and may protect against developing diabetes. Additionally, maintaining muscle mass becomes more important as you age, as it can help with mobility, balance, and strength.
Lean body mass includes muscle mass, but it also includes bone, skin, water, organ mass, and other components. Muscle mass specifically refers to the weight and size of smooth muscle tissue in the body, including skeletal, smooth, and cardiac muscles.
Muscle mass is typically expressed as a percentage of total body composition. It can be calculated by measuring body fat percentage and subtracting that from total body mass to get "fat-free mass." However, this method does not provide a precise measurement of muscle mass as fat-free mass includes bone mass, which varies between individuals.
Strength training or resistance training is an effective way to build muscle mass. This involves forcing your muscles to work against resistance, which creates tiny tears in the muscle fibers that the body then repairs and adapts to, leading to increased muscle mass. Eating a nutrient-dense and protein-rich diet is also key to gaining and maintaining muscle mass.
