Which muscles arm wrestling?


Arm wrestling is a sport that requires a unique combination of strength, technique, and leverage. The success of an arm wrestler depends on various muscles that work together to generate force and control the opponent’s arm. In this article, we will explore the key muscles involved in arm wrestling.

The Arm Wrestling Technique

Before we delve into the specific muscles, it’s important to understand the technique behind arm wrestling. The objective is to pin the opponent’s hand and wrist onto a designated surface. This requires a combination of arm flexion, wrist flexion, and pronation (rotating the palm down).

The Muscles Involved

1. Biceps Brachii

  • Location: The biceps brachii, often referred to as the biceps, is located on the front of the upper arm.
  • Function: The primary function of the biceps is to flex the elbow. In arm wrestling, it plays a crucial role in initiating the movement and generating force.

2. Brachialis

  • Location: The brachialis is a muscle beneath the biceps, situated on the front of the arm.
  • Function: It is a powerful elbow flexor, providing additional force in the arm wrestling motion.

3. Brachioradialis

  • Location: The brachioradialis is located on the forearm, near the elbow.
  • Function: It aids in both elbow flexion and pronation, contributing to the overall force exerted in arm wrestling.

4. Pronator Teres

  • Location: This muscle is found on the forearm.
  • Function: As the name suggests, it is responsible for pronation of the forearm, a crucial movement in arm wrestling.

6. Wrist Extensors

  • Location: Situated on the outer side of the forearm, these muscles oppose the wrist flexors.
  • Function: They help stabilize the wrist and maintain control during the match.

Training for Arm Wrestling

Developing strength and coordination in these key muscles is essential for success in arm wrestling. Incorporating exercises that target these muscle groups, such as bicep curls, wrist curls, and pronation drills, can be beneficial.


Arm wrestling requires a unique combination of muscle strength, technique, and leverage. Understanding the specific muscles involved, their functions, and how they work together is crucial for success in this sport. By targeting these muscles in your training regimen, you can improve your arm wrestling performance and increase your chances of winning matches. Remember to train safely and consult a fitness professional if you have any concerns about your training routine. With dedication and strategic training, you can become a formidable arm wrestler.
