What Muscle Is Arm Wrestling?

Arm wrestling is a thrilling and competitive sport that showcases the strength and power of the human body. It is a test of raw strength, technique, and endurance. While arm wrestling involves multiple muscles working together, there is one key muscle group that plays a vital role in determining success: the forearm. In this blog post, we will explore the primary muscle responsible for arm wrestling and how to train and develop it to excel in this challenging sport.

The Forearm: The Powerhouse Of Arm Wrestling

The primary muscle group that comes into play during arm wrestling is the forearm. The forearm consists of several muscles that work together to generate the necessary force and stability required for arm wrestling. The key muscles involved are:

  1. Brachioradialis: Located on the outer side of the forearm, the brachioradialis is a powerful muscle that aids in flexion and rotation of the forearm. It plays a crucial role in generating the initial force during an arm wrestling match.
  2. Pronator Teres: Situated on the inner side of the forearm, the pronator teres muscle helps in pronation, or the rotational movement of the forearm. It contributes to the twisting and turning motions involved in arm wrestling.
  3. Flexor Carpi Radialis: Found on the inner side of the forearm, the flexor carpi radialis muscle assists in wrist flexion, which is essential for creating leverage and maintaining control during arm wrestling.
  4. Flexor Digitorum Profundus: This muscle, located deep within the forearm, aids in finger flexion. Although finger strength is not the primary focus in arm wrestling, having a strong flexor digitorum profundus can provide additional stability and grip strength.

Training The Forearm For Arm Wrestling:

Developing a strong and powerful forearm is crucial for success in arm wrestling. Here are some exercises and techniques to target and strengthen the forearm muscles:

  1. Wrist Curls: Wrist curls are a classic exercise for forearm development. Holding a dumbbell or barbell, rest your forearms on a flat surface with your palms facing up. Slowly curl your wrists upward, then lower them back down. Repeat for several sets, gradually increasing the weight as your strength improves.
  2. Reverse Wrist Curls: Similar to wrist curls, reverse wrist curls target the muscles on the back of the forearm. With your palms facing down, curl your wrists upward against resistance. Focus on controlled movements and gradually increase the weight over time.
  3. Pronation and Supination Exercises: Perform exercises that involve forearm rotation, such as using a dumbbell or a wrist roller. Hold the weight in your hand and rotate your forearm inward (pronation) and outward (supination) in a controlled manner.
  4. Grip Strength Training: Strong grip strength is essential for arm wrestling. Utilize grip-strengthening exercises like farmer’s walks, hanging from a pull-up bar, or using grip trainers or hand grippers. These exercises target not only the forearm muscles but also the muscles in the hand and fingers.
  5. Arm Wrestling Specific Drills: Engage in arm wrestling-specific drills and practice matches to improve technique, endurance, and overall arm wrestling skills. These drills will involve applying force and resistance from various angles, simulating real arm wrestling scenarios.

Remember to warm up properly before any workout, and listen to your body to prevent injuries. Gradually increase the intensity and weight as your strength and endurance improve.


Arm wrestling is a thrilling sport that requires a combination of strength, technique, and strategy. While multiple muscles contribute to the arm wrestling motion, the forearm muscles play a pivotal role in generating power and control. By incorporating targeted forearm exercises and grip-strengthening routines into your training regimen, you can develop the necessary strength and endurance to excel in arm wrestling. With dedication, proper technique, and a strong forearm, you’ll be ready to take on any arm wrestling challenge that comes your way.
