Muscle circumference is a way to measure the changes in muscle dimensions over time. It is a way to determine body size, composition, and to monitor changes in these parameters. It is a good way to track progress in addition to weighing yourself. Muscle circumference is usually measured with a tape measure and can be done on various parts of the body, including the bicep, forearm, upper arm, chest, calves, thighs, and hips. Mid-upper arm circumference (MUAC) is a widely used method for assessing nutritional status, and it can also be used to estimate the prevalence of malnutrition in populations. It is important to note that muscle circumference does not account for fat tissue, which can also contribute to the circumference of a body part.

What You'll Learn
Arm muscle circumference (AMC)
Muscle circumference is a method to determine body size, composition, and monitor changes in these parameters over time. Arm Muscle Circumference (AMC) is a decades-old anthropometric measurement of the amount of muscle in the arm. It is calculated by measuring the upper arm circumference with a flexible tape measure and the triceps skinfold thickness with calipers. AMC provides an indirect measure of the total amount of muscle or protein in the body. Mid-upper arm muscle circumference (MUAMC) and upper arm muscle area (AMA) are estimates of upper arm muscle and body composition. They are calculated from measurements of MUAC and TSFT on the assumption that the arm is cylindrical and the subcutaneous fat is equally distributed.
MUAC is a simple and practical tool that can be used to detect severely malnourished individuals in a community and to achieve high program coverage. It is a measure of the sum of the muscle and subcutaneous fat in the upper arm. It is measured in adults and children, using a flexible non-stretch tape laid at the midpoint between the acromion and olecranon processes on the shoulder blade and the ulna, respectively, of the arm. MUAC is also recommended for rapid identification of severe acute malnutrition (SAM) in a community – MUAC of less than 115 mm being indicative of SAM.
AMA is a better indicator of total body fat than TSFT alone. It can be calculated from revised formulae that take account of errors resulting from the non-circular nature of muscle and the inclusion of non-skeletal muscle with MUAC and TSFT in cm. However, AMA cannot be used to monitor changes in muscle stores because of the problems in making this measurement. The ratio of AMA to total body muscle mass changes with age and certain diseases.
Simplified muscle mass body indices like AMC have significant predictive value for assessing cardiovascular risk in both healthy populations and patients with type 2 diabetes mellitus (T2DM).

Mid-upper arm circumference (MUAC)
Muscle circumference is a method to determine body size, composition, and to monitor changes in these parameters. Mid-upper arm circumference (MUAC) is a measurement that allows health workers to quickly determine whether a patient is acutely malnourished. It is a measure of the sum of the muscle and subcutaneous fat in the upper arm. MUAC is measured using a flexible non-stretch tape laid at the midpoint between the acromion and olecranon processes on the shoulder blade and the ulna, respectively, of the arm. It is measured to the nearest 0.1 cm.
MUAC is also recommended for rapid identification of severe acute malnutrition (SAM). A MUAC of less than 115 mm is indicative of SAM. An MUAC of less than 12.5 cm suggests malnutrition, while a MUAC of greater than 13.5 cm is considered normal. MUAC can be used for screening in emergency situations and for estimating the prevalence of malnutrition in populations but is not typically used for evaluation purposes.
MUAC can be used as an indicator of body composition in adults and children. It can be used in preschool children as an age-independent screening tool for severe malnutrition. Since the rate of change of arm circumference is slow, it cannot be used to assess growth or monitor the response to therapy. However, MUAC-for-age indicates body composition (upper arm fat and muscle) in adults and children when used with measurements of weight and height. MUAC measurements are compared with reference values by age and sex.
Mid-upper arm muscle circumference (MUAMC) and upper arm muscle area (AMA) are estimates of upper arm muscle and, therefore, body composition. They can be used as indicators of muscle mass and protein stores. AMA is a better indicator of total body fat than TSFT alone. However, AMA cannot be used to monitor changes in muscle stores because of the problems in making this measurement.

Upper arm muscle area (AMA)
Muscle circumference is an old anthropometric measurement of the muscle in the arm, which reflects the total amount of muscle or protein in the body. Girth Measurement is a method to determine changes in body dimensions over time. It is the circumference measured at standard anatomical sites around the body using a tape.
> AMA = k * MUAC^2
> Where k = 0.31696 - 0.01669 * TSFT + 0.00073 * MUAC
AMA can be compared with reference values by age and sex. The ratio of AMA to total body muscle mass changes with age and certain diseases. However, AMA cannot be used to monitor changes in muscle stores because of the problems in making this measurement.
AMA is also used in the assessment of newborn infants who have experienced either fetal growth restriction or acceleration. It can be used to identify reduced muscle or fat stores in growth-restricted infants who might be classified as AGA by weight criteria.

Tracking progress
Choose Measurement Sites
Select the areas of your body that you want to measure. Common sites for taking body circumference measurements include the waist, forearms, upper arms, chest, calves, thighs, and hips. These sites provide insights into changes in your body composition, such as fat loss or muscle gain.
Prepare Measurement Tools
You will need a flexible measuring tape, preferably one used for sewing due to its flexibility and ease of finding. Additionally, ensure you have minimal clothing on during measurements, as clothing can affect the accuracy of the results. Mark the measurement sites on your skin with a pen to ensure consistency.
Take Measurements
Stand in an erect posture with your feet together and relax your arms by your sides. When measuring your waist, ensure your abdominal muscles are not contracted. Wrap the tape around the chosen sites, ensuring it is flat on the skin and horizontal. Take measurements in inches or centimetres, being careful not to pull the tape too tight or leave it too loose.
Record and Compare
Record all your measurements and compare them over time. You can also take monthly progress photos, ensuring consistency in clothing, location, and lighting. This visual comparison can provide additional insights into changes in your body composition.
Consider Other Factors
Remember that muscle circumference is just one aspect of body composition. Other factors, such as height, diet, ethnicity, fitness level, and overall body fat, also play a role in determining overall health and progress. Consider using other tools, such as skinfold measurements or imaging tests, for a more comprehensive understanding of your progress.

Muscle-building exercises
Muscle circumference is a method of measuring the amount of muscle in the body, specifically the arm. It is calculated by measuring the upper arm circumference and the triceps skinfold thickness.
Some examples of muscle-strengthening exercises include:
- Leg press: This exercise targets your leg muscles. Place your feet on the plate with your knees bent and slowly push the plate out until your knees are straight.
- Squats: Squats target your thighs and glutes. Use a barbell that is heavy enough to challenge your muscles but light enough for you to maintain your form.
- Dumbbell bench press: This exercise targets your chest muscles. Slowly lower the weight until it touches your chest, then exhale and press back up.
- Standing dumbbell hammer curl: This exercise targets your arm muscles. Hold the weights at your sides and slowly raise one straight arm to shoulder level while turning your palm towards the floor.
It is recommended that adults do at least two strength training sessions per week that target all of the major muscle groups. It is important to note that building muscle mass can be challenging and may take time. Genetics, age, height, diet, ethnicity, and fitness level all play a role in muscle growth. Consulting with a doctor or personal trainer can be helpful in developing an effective exercise program.

Frequently asked questions
Muscle circumference is a measurement of the amount of muscle in a particular part of the body. It is usually measured in the upper arm, bicep or forearm, but can also be measured in the torso, chest, calves, thighs and hips.
Muscle circumference is important because it provides an indication of the total amount of muscle or protein in the body. It can be used to monitor changes in body composition and is a good way to track progress in fitness goals, such as gaining muscle or losing fat.
Muscle circumference is measured using a flexible tape measure. The tape should be placed directly on the skin, with no clothing underneath, and should be flat and horizontal. Measurements should be taken at the same points and in the same way each time.
Muscle circumference is influenced by a variety of factors, including height, diet, ethnicity, fitness level, age and sex.
To increase muscle circumference, focus on strength training and nutrition. Weightlifting and resistance exercises can help to build muscle mass, while a nutrient-dense, balanced diet with sufficient protein will fuel muscle growth and repair.
