How big should a 15 year old boys bicep be?

Answer 1

i am 5,2 and 12 years old i am what you would consider to be muscullar for my age unflexed i am 12 inches flexed i am 13 inches

Answer 2

I think from looking around it is about 11in. which is how big my arms are. Some people have bigger arms but most of the time its not all muscle but some times it is.

Answer 3

Oh, how exciting! Remember, everyone's body is different and unique, just like a happy little tree. Focus on being healthy and strong rather than comparing yourself to others. Keep painting those happy little muscles with exercise and good nutrition, and your biceps will grow in their own time.
