Arms

The triceps is the major muscle group in the back of the arm and is trained during all pressing exercises. The triceps is opposite the biceps and works to extend the elbow. The primary muscles in the front of the arm include the biceps brachius and brachialis. These muscles, along with the triceps and forearm (discussed separately) provide strength, grip strength, flexibility, and power in sports requiring constant use of the arm. Proper weight training exercises can reduce the risk of "tennis elbow" and other injuries which can limit your performance.
