Biceps vs. Triceps: Know the Difference
By Shumaila Saeed || Published on February 4, 2024
Biceps are the two-part muscles at the front of the upper arm, responsible for flexing the elbow; triceps are the three-part muscles at the back, responsible for extending the elbow.
Key Differences
The biceps, a two-headed muscle, is located at the front of the upper arm and is primarily involved in the flexion and supination of the forearm. In contrast, the triceps, a three-headed muscle, is situated at the back of the upper arm and plays a crucial role in the extension of the elbow joint.

Functionally, the biceps are key in lifting and pulling movements due to their role in bending the elbow and rotating the forearm. Conversely, the triceps are essential in pushing movements, as they straighten the arm at the elbow.

In terms of structure, the biceps consist of a long head and a short head, each contributing to the muscle's overall shape and function. The triceps, on the other hand, comprise a lateral, medial, and long head, each with specific roles in arm and shoulder movements.
