There are several ways to measure muscle mass, each with its own advantages and drawbacks. The cheapest but least accurate way is bio-impedance, which involves sending an electrical current through the body and measuring how much body fat there is. Another way is to use a measuring tape to measure the circumference of different body parts, such as the bicep and thigh. This method is more accurate than visual inspection but may still be inaccurate, especially for overweight people. A more advanced method is body composition analysis, which can be done through a DXA scan or a body weighing scale. The most accurate way to calculate muscle mass percentage is through magnetic resonance imaging (MRI), but it is very expensive.

What You'll Learn
Body fat scales
However, it is important to note that body fat scales are not completely accurate and are limited in their ability to provide a full picture of body health. Firstly, body fat scales do not show where a person's body fat is stored, which is an important consideration when assessing an individual's susceptibility to disease. For example, abdominal fat has been associated with a higher risk of developing cardiovascular disease. Secondly, the accuracy of body fat scales can be affected by a person's hydration status, with dehydration potentially leading to an overestimation of body fat, and overhydration leading to an underestimation. Other variables that can affect the results include gender, age, height, and stature. Women, for instance, naturally have more body fat than men. Additionally, the design of the scales can impact accuracy, with longer-legged individuals potentially receiving an overestimate of body fat percentage due to the longer journey of the electrical signal.
Despite these limitations, body fat scales can still be a reasonably accurate way of tracking body composition trends over time when used under the same circumstances regularly. They are also more accessible than other methods of measuring body fat, such as DEXA (dual-energy X-ray absorptiometry) scans, which are typically used for bone density testing, or underwater weighing (UWW), which is mostly available in research laboratories.
It is recommended that individuals use body fat scales in conjunction with other methods of determining body health, such as Body Mass Index (BMI), which calculates whether a person is in the right weight range for their height and age. However, BMI also has limitations as it does not take into account a person's muscle mass or the location of body fat. Therefore, while body fat scales can be a useful tool, it is important to consult a skilled medical provider or dietitian to make sense of the results and receive guidance on diet and exercise.

Body circumference measurements
To take body circumference measurements, you will need a flexible, inelastic tape measure. A cloth measuring tape is a good option, or you can use a tape measure specifically designed for taking body measurements, such as the MyoTape Body Tape Measure.
- Take measurements against bare skin, with no clothing.
- Keep the tape measure flat against the skin, with no twists or bumps.
- Apply the same tension to the tape measure each time you take a measurement.
- Take each measurement at least twice and record the average value.
- Take measurements at the same time of day and under the same conditions for consistency.
- Avoid flexing the muscle when taking a measurement, as this can distort the results.
- Neck: Stand upright and wrap the tape measure just above your Adam's apple.
- Shoulders: Stand upright and wrap the tape measure around the most perpendicular protrusions of your shoulders.
- Chest: Stand with your feet together and torso straight, and wrap the tape measure around the widest part of your bust, passing by the nipples.
- Calves: Measure halfway between the knee and the ankle, at the bulky area of the lower leg.
- Thighs: Measure at the midpoint between the lower part of the glutes and the back of the knee, or the widest part of the thigh.
- Waist: Find the narrowest part of your torso and wrap the tape measure around it.
- Hips: Stand sideways and look in a mirror to find the widest part of your glutes. Wrap the tape measure around this point, ensuring it is parallel to the floor.
- Buttocks: Stand upright and strain the muscles at the back. Wrap the tape measure around the far ends of the muscles.

DXA scans
During a DXA scan, you lie on a special X-ray table, where a technician will help position your body and ensure you are comfortable. They may place foam blocks under or around you to hold your legs in the correct position. The technician will then pass a scanning arm over your body, capturing images of your bones, with fat, muscles, and other soft tissues appearing as dark shadows in the background. The procedure is quick, painless, and non-invasive, with no needles or injections involved.
To prepare for a DXA scan, it is recommended to stay well-hydrated and refrain from eating for at least three hours beforehand. Metal objects, such as jewellery, watches, and zippers, can interfere with the scan, so it is advisable to remove or minimise these items. Lightweight clothing is preferred, and you may be asked to wear a hospital gown during the procedure.

Bio-impedance
BIA is a popular method for estimating body composition and is used in many commercial gyms and for research on group body composition. However, it is generally considered less accurate than methods used in clinical or nutritional and medical practice. BIA tends to underestimate body fat percentage, and the accuracy of the measurement depends on the quality of the device and other factors such as body weight, hydration level, and ethnicity. For instance, BIA may be less accurate for people with obesity or if measurements are taken after a meal, as body fat measurements tend to be lower after eating. Additionally, moderate exercise before BIA measurements can lead to an overestimation of fat-free mass and an underestimation of body fat percentage.
Despite its limitations, BIA can be a useful tool for tracking changes in body composition over time. It is the cheapest method for measuring muscle mass and can provide insights into an individual's body composition and muscle-building progress when used consistently. However, it is important to manage expectations and understand the potential for measurement errors when using BIA.
To improve the accuracy of BIA measurements, researchers have explored the use of multiple frequencies or bioimpedance spectroscopy (BIS) devices. These devices estimate resistance at zero and high frequencies and theoretically provide better predictions of body composition. While the improvement in accuracy is marginal, the use of multiple frequencies in BIA devices has been shown to correlate highly with DXA measurements of body fat percentage.

Progress pic tracking
Firstly, consistency is key. Try to keep the setup of your photos as consistent as possible. This includes wearing similar or the same outfits, using the same lighting, and maintaining the same background and camera angle. Natural daylight is ideal as it accurately reflects how your body looks daily. If you can't take photos during the day, ensure the room is well-lit without shadows that can distort your body. Taking photos at the same time of day and in the same location is also beneficial.
Next, ensure you capture your entire body in the photo. Avoid the traditional handheld fitness selfie, as it often doesn't show the whole body and the angle can be unflattering. Instead, place your camera or phone on a stable surface, set a timer, and get in front of it. For women, a sports bra and shorts are recommended, while men can wear sports shorts or briefs. This ensures that changes in your body are easily noticeable.
Additionally, consider using a digital journal to record your progress pics. Digital journals offer advantages over paper journals, such as the ability to see snapshot views of your progress, collaborate with others working towards similar goals, and securely back up your data. You can also include journal entries alongside your progress pics to document your journey more comprehensively.
Finally, remember that progress pics are not just for tracking but also for motivation. Side-by-side comparisons of your journey can be a massive confidence boost and a great reminder of how far you've come. They can help you stay fired up to achieve your fitness and nutrition goals. So, don't forget to celebrate your milestones and embrace the magic of progress pic tracking!
