There are several ways to measure or calculate muscle mass, but the only way to directly measure it is through cadaver dissection, which is not usually a viable option. The most accurate way to measure muscle mass is to first calculate your fat mass, but these tests tend to be costly and hard to access. Less accurate formulas can give you an idea of your muscle-to-fat ratio, but they might be a little off. One of the least accurate methods of measurement is called BMI, or body mass index, which doesn't take body composition into account. Electrical impedance scales are a quick, easy and relatively cheap way to measure body fat and muscle mass at home, according to Dr Womack.

| Body mass index (BMI) | A measure of weight versus height (kg/m2). BMI does not take body composition (fat vs. lean body mass) into account. |
| Lean body mass | The weight of the bones, organs, skin, muscles and water in your body. |

What You'll Learn
Body mass index (BMI)
BMI is a quick and easy way to get an idea of whether your weight is healthy, but it is not a highly accurate measure of body composition. This is because it does not distinguish between fat mass and lean mass. Lean mass includes the weight of bones, organs, skin, muscles and water in your body.
There are other ways to measure muscle mass, but they tend to be costly and hard to access. One way to get an idea of your muscle-to-fat ratio is to first calculate your fat mass. You can then subtract this from your total body weight to get your fat-free mass, which includes your muscle mass.
It is important to remember that all of these methods are estimations and none of them are highly accurate or non-invasive. The only way to directly measure muscle mass is through cadaver dissection, which is not usually a viable option!

Electrical impedance scales
Bioelectrical impedance analysis (BIA) is a popular method of measuring body composition, and is used in many commercial gyms and in research. However, it does not appear to provide valid measures of body composition for athletes.
One of the least accurate methods of measurement is body mass index (BMI), which is a measure of weight versus height. While it is useful in some cases, it does not take body composition into account, so someone who is very muscular can end up being classified as overweight or obese according to their BMI.

Fat-free mass
There are several different methods for measuring or calculating the amount of body muscle mass. However, the only way to directly measure muscle mass is via cadaver dissection, which is not usually a viable option. Therefore, it's best to focus on lean body mass or fat-free mass.
There are other methods for calculating fat-free mass, but they tend to be costly and hard to access. Some are easy to do at home, while others require heavy machinery that can only be found in a doctor's office or sports research lab.

Lean body mass
There are several methods to calculate fat mass, but they tend to be costly and hard to access. One of the least accurate methods is body mass index (BMI), which is a measure of weight versus height. It is calculated by dividing your body weight in kilograms by your height in meters squared. However, BMI does not take body composition into account, so someone who is very active and has a lot of muscle but very little body fat can end up with a falsely high BMI.
A more accurate way to measure body fat and muscle mass at home is to use an electrical impedance scale. These are quick, easy, relatively cheap, and useful for following trends over time.

Cadaver dissection
The only way to directly measure muscle mass is through cadaver dissection, which is not usually a viable option. This is because cadaver dissection is an invasive procedure that is costly and hard to access.
While cadaver dissection provides an accurate measurement of muscle mass, it is important to note that it is not always practical or ethical to perform such a procedure. Therefore, other methods of estimating muscle mass are often used, although these methods may be less accurate.
One common method of estimating muscle mass is by calculating the fat-free or lean body mass. This can be done by measuring the body's fat mass and then subtracting it from the total body weight. This method provides an estimation of the muscle mass in the body, as muscle mass is a component of lean body mass.
Another method of estimating muscle mass is by using body mass index (BMI), which is a measure of weight versus height. However, BMI does not take into account body composition, such as the ratio of fat to lean body mass. As a result, BMI can be misleading, especially for individuals with a low body fat percentage and a high amount of muscle mass.

Frequently asked questions
The most accurate way to measure muscle mass is to first figure out your fat mass. You can then measure the change in muscle mass by measuring your fat-free mass at two separate points.
The first and least accurate method of measurement is called BMI, which stands for body mass index. It's a number that is simple to figure out, which is why it's used so often in fast-paced environments like a doctor's office. All you need to do is divide your body weight in kilograms by your height in meters squared.
Dr Womack says that using one of these electrical impedance scales is the best way to measure body fat and muscle mass at home. "It's quick, easy and relatively cheap, and useful as long as you're not worried about the exact number but just looking to follow the trend," he says.
The only way to actually directly measure muscle mass is via cadaver dissection, which is not usually a viable option! There is no highly accurate and acceptable noninvasive technique of measuring muscle mass.
