Anyone know anyone that is pretty slender, but when he flexes his bicep is the highest peak I have seen. I have often arm wrestled him, and he's pretty strong, but wondering if this freaky high peak is mostly genetics. I've never measured it, but I'm guessing it's at least 15".

My friend is a tennis player, so is somewhat right arm dominant and isn't particularly thick but very high peaked. I would say he's got long muscles so the appearance is huge.

Anyone havesimilar experiences or pics?
