Training

To sculpt bigger, stronger biceps and triceps, it helps to arm yourself with a bit of knowledge about your arm muscles and how they work.Your upper arms are divided into three main muscle groups. Firstly, we have the biceps, which runs along the front of the arm, from your elbow to your shoulder joint. The main function of the biceps is to bend the elbow. Secondly, we have the triceps that also run from the elbow to the shoulder, but their main role is to straighten the elbow.
