The bicep is a two-headed muscle (hence its name) located on the upper arm's front side. The short head of the bicep resides on the inside, while the long head is positioned outside. The primary function of the bicep is elbow flexion - think bicep curl.
Beneath the two heads, we also have the brachialis - a deep muscle that assists with elbow flexion. Developing it contributes to your overall arm size as it pushes the bicep up, making it appear larger.
Like with most other muscle groups, we can emphasize one head over the other, depending on the exercise and specific technique we choose to use.
For example, if you want to emphasize the bicep's long outer head, you should use a narrower grip where your elbows are close to your body and your forearms point forward and in. In contrast, to emphasize the short inner head, you should use a wider grip where your forearms point forward and out.
The idea of bicep training seems very simple, doesn't it? Use a dumbbell to curl it for a few sets. The principle behind bicep training is largely that. It is important to gain a deeper understanding of this muscle group before you can realize its full potential.
