How do you develop muscles near elbows?

[sandals]

I feel my lagging part are my arms! But particularly the
area - near the elbows. My arms near shoulders develop
easy, tris are good even have a good peak in forearms.

But near the elbows there seems to be less muscle mass. I want what some men have - a outward bulge
when arm is bent & "heavy" muscle hanging over the
elbow in the back of the arm when almost straight.
Maybe I just have long arms, I'm 5'11". What arm excer.
should I do ?

You need to post this on the training board.
