Arm Growth

[InternalFire]

Ive seen guys with amazing bicep developement and no tricep mass, he looked like shit in general, the only time arm looked good when he had his arms down and were palms facing front, turn the guy few degree and show is over.

I also have seen guys with minimal bicep development and huge tricep mass development and that arm looked amazing big, tricep fills an arm so much and almost seems it brings up bicep and gives illusion of bicep thickness.

And where guys had worked out tricep to a higher degree than the bicep but still bicep wasn't lagging either, now those seemed like they were the guns that resemble of guys at the top level.

Hi guys - thanks for the tips.

The photo of arm attached represents 15.25" at 12% BF. Btw: would 12% BF be considered "low"?

I absolutely agree about triceps: it is a very underrated muscle group - but looks truly awesome when developed to its full potential - even when arm is not flexed!
I started using Overhead Tricep Extensions and Close-Grip Benchpresses to target the triceps recently. I do find, unfortunately, that the extensions give me pain in the elbows after a while - hence prefer the benchpress.

Muscle density was mentioned - is that genetically predetermined, or do exercise types really change that too - any thoughts?

From my photo - I was wondering what a low or high insertion would look like? I'm guessing from my arm, it looks like a low insertion - I would like to know.

I also would appreciate any advice / feedback on my arms - I am a relative beginner hence the under 16" arms at the mo. - more work on the triceps? or biceps?, or forearms?

Cheers,
