Generally, the arm circumference of normal boys who don't exercise is around 28, that of men who often do manual labor is around 30, that of men who often exercise is around 35, and some people can even reach 40.

The creation of "unicorn arm" is naturally no less than that of any bodybuilder. Now the arm circumference is over 30, and the sebum is very low. If you work hard, it is easy to reach a higher level. Although this arm circumference is considered as a thin monkey by many bodybuilders, it is still very confident compared with most adult men who do not exercise.

Compared with other normal men before, it is roughly estimated that normal men who don't exercise will reach 27, but when they meet a few men who have been doing heavy work for a long time, although they can't compare with each other in terms of arm circumference, they will definitely win from an aesthetic point of view, so most normal men's arm circumference is not as good as that of fitness men.

The thick arms are not necessarily strong, which may be because of the thick fat, but using the word arm circumference to describe it is inseparable from fitness training. At this time, the arm circumference is large, and of course the muscle strength is also large. "Unicorn arm" trained by lifting iron in fitness.

Its strength should not be underestimated. As far as the author's three-legged cat's arm circumference of 30 points is concerned, it can't catch up with the wrists of more than a dozen normal adult men. Basically, I have never been healthy, I have never done heavy work, and I have never lost in my impression. Therefore, there is a big gap between muscle circumference and strength.
