Nah, triceps make up most of your arm size curls are only half the story.

Definition comes from low body fat just as much as arm training.

You want sharp arms? Train triceps, brachialis, and forearms too.

Curls build peaks, but triceps build the horseshoe.

Heavy compounds grow arms more than people wanna admit.

No amount of curls fixes high body fat, simple truth.

Pull-ups, dips, presses — that’s where arm thickness really comes from.

Arm definition = muscle + conditioning, not just mirror curls.

Most dudes overtrain biceps and forget triceps completely.

If you only curl, your arms will look decent from one angle.
