What is the other side of your bicep called?
But there is another muscle that you can see at the side of your biceps, at least if you’re at a low-enough body fat. That muscle is sometimes mistakenly referred to as the side biceps, but it’s actually a separate muscle called the brachialis. Training this muscle helps make your arms appear bigger and more defined.
