Arm wrestling is a compound movement that involves multiple muscle groups of the upper body at different stages. The primary muscles used in arm wrestling are:
-
Forearm muscles: The forearm muscles, including the flexors and extensors, are responsible for flexing and extending the wrist and fingers. These muscles are generally thought to be the most important with the upper arm and chest providing additional strength.
-
Biceps: The biceps, located in the front of the upper arm, are responsible for flexing the elbow and rotating the arm. They play a significant role in generating the power needed to win an arm wrestling match.
-
Triceps: The triceps, located in the back of the upper arm, are responsible for extending the elbow. They are also crucial for generating the power needed to win an arm wrestling match.
-
Pronator teres: This muscle is located in the forearm and is responsible for rotating the forearm inward.
-
Pectoralis major: This muscle is located in the chest and provides additional strength during arm wrestling.
-
Flexor carpi ulnaris: This muscle is located in the forearm and is responsible for flexing the wrist.
-
Deltoids, rotator cuff, and trapezius: These shoulder muscles provide stability and control during the arm wrestling match.
Its important to note that depending on the technique and where you are in the range of motion, the muscles you're actively engaging will differ.
