Article: If you've exercised your arms right before you measure your bicep size, you won't get an accurate bicep measurement. Working out forces blood into your muscles, which temporarily inflates the size of your biceps and triceps. If you're planning to measure your arms and work out in the same day, always take the measurements first. Wrap a tape measure around both your biceps at their thickest point, near your armpit. Measure one arm after the other. Measuring both biceps will help you compare your arms against each other, and figure out if you need to work one more than the other. Ideally, both biceps should be the same size. For accurate, consistent measurements, make sure that the material of the tape measure is flat against your skin. Don't pull or distort the tape, or you'll risk stretching it and distorting your measurement. Make sure that there are no twists or bumps in the tape when you're measuring. You should also never measure your bicep through a shirt. If you're wearing a t-shirt, roll the sleeves up. Otherwise, remove your shirt so that you're measuring directly against the skin of your arm. You'll get reliable and consistent measurements if you measure your bicep when it's relaxed. Let your arm hang down beside your body, and keep your muscles relaxed while measuring them. Consistency is the most important part of measuring any body part for bodybuilding, and it's easier to get consistent measurements if you don't flex. Your muscles will flex different amounts from day to day, so measuring the relaxed muscles will provide the most accurate results.
Question: What is a summary of what this article is about?
Measure before you weight lift. Measure at the thickest part of both biceps. Hold the measuring tape flat against your skin. Do not flex your biceps while measuring.
