What is the average arm muscle size of a 14-year old boy?

I ment to say I can dumbell press 40kg on each on not lb sorry

That’s going to be pretty impossible to tell… every person at any stage of age come in different shapes or sizes.

About 12in circumfrence… If you work out (15 year old)

mysterywolf is right. your muscles are the size they are because of how much you work out and what you naturally got from your mom and dad

there is no set size, only the way you live your life will change your body

I’m 15 and I work out rarely and I have about 17in girth around my arm.

my family has a vary healthy lifestyle and not being lazy helps a lot

I knew a 14 year old that had a 16in and he was a big kid. it wont matter so long as you arnt unhealthy

Size doesn’t matter if its soft and squishey. I’m 15 and I do curls of 50 lbs and my arms are 14” circumferance. And theres a kid on my football team and his arms are like 22” circumferance, but he only does curls of 30lbs.

well seriously I got arms as big as 15 inches and im only 13, it takes a lot of time and patience to get big arms , I’ve spent 2 years from grade 6, to grade 8 to get my arms to the size they are now,

TIP : dont push yourself to hard or your gonna hurt yourself

is it when you FLEX or not? you have 12in girth without flexing?

I am 15 and my arm circumference is 12 1/2 is that normal?

Me I have 14 years old and me arm measured 8 inch is normaly. And I meadured 5’6

I am 16 and my arms are 12 Inch.I dont train my arms.

My friend Clive has big arms and he’s only 49. Lololol at strong unawares.

I have a friend named Clive and he’s pretty cool. Lololol at strong unawares.

14 inches I guess. When I was 13 they were 13 inches around. Now I’m 16 and they are 16 inches around. So I guess the measurement is same as your age. I can’t wait to turn 100 :P
