Did you know the bicep is actually comprised of two distinct muscle heads, not just one? Understanding this fundamental anatomical fact is key to building well-proportioned, powerful arms. This guide explains exactly what is the inner and outer bicep, and how to train them effectively.

While the prefix 'bi' correctly indicates 'two', leading to the common understanding of a two-headed muscle, the query **What are the three heads of the biceps brachii?** points to a fascinating anatomical variation. The standard biceps brachii muscle is composed of the long and short heads, but some individuals are born with an extra, or supernumerary, head.

Contrary to the anatomical name *biceps brachii*, which means 'two-headed muscle of the arm,' many fitness enthusiasts refer to three key muscular components that contribute to the size and shape of the upper arm. This distinction helps people understand not only the primary muscle but also the deeper, supporting structures. For those wondering **what are the three parts of your bicep?**, the answer involves a closer look at the complete muscular picture of the upper arm's front section.
