The muscle group that we will learn how to measure in this article is the biceps, which are actually made up of two heads. However, that won’t really affect how we measure them so we’ll leave that for another article. In this case, you will need to find a partner to help you properly measure your biceps, as well as a measuring tape that is flexible and seamless. The best ones for this are those used by a seamstress or tailor because they are long enough and wrap perfectly around the biceps and other muscle groups.

Once you’ve got your tape, then you can start measuring biceps. Make sure that you aren’t measuring right after a workout, well unless you want inaccurate results. Make sure you haven’t used your biceps for a major workout in a day or two for best results.

Take 3 measurements around your biceps and make sure that all measurements are from the upper peak of the bicep and wrap fully around the arm. If your 3 measurements are off by more than an eighth or a quarter of an inch, then you need to strike them and try again until they all fit within a solid group.

Once you’ve got three good measurements, then you can take the average by adding them up and dividing by three. This should give you an accurate biceps measurement. Although this isn’t “official” per se, it is the way that most bicep readings are taken. If you want to learn how to take official measurements, then you will need special equipment that isn’t worth buying unless you need to. Otherwise, simply keep weekly measurements using this method and you will have no problem keeping track of your progress.
