13 inch biceps aren’t so enormous for a natural lifter because that size is typical for biceps when they’re not flexed (your flexed measurement should always be bigger than your unflexed measurement). A 13-inch bicep circumference, though, may be substantial.
Although your 13-inch flexed biceps are undoubtedly below average for guys 20 and older, there is still a chance that you can grow them to 15, 16, or 17 inches, making them into monstrous monsters. Read more
More About 13 Inch Biceps
13 inch biceps Having said that, it is true that 13-inch biceps are somewhat twiggy. We are aware of this because, between 2015 and 2018, the CDC gathered anthropometric data, which is another word for “body measurements.”
The CDC doesn’t say whether these measurements are taken with the muscles flexed, relaxed, or “pumped.” However, if we had to hazard a guess, we would suggest that measurements were obtained with the arms at the sides.
This proves that your 13-inch biceps are far less than you initially believed. For men between the ages of 20 and 29, the typical upper-arm measurement is probably closer to 14 than 15 inches.
However, it’s also important to remember that “biceps measurements” refer to more than simply the biceps brachii. It also comprises the triceps, a three-headed muscle at the rear of the arm that accounts for 60–70% of upper arm mass, as well as the brachialis, the muscle tucked beneath the biceps brachii.
