The biceps curl is a fundamental exercise targeting the biceps muscles, the muscles on the front of your upper arm. No other muscles are directly involved in a biceps curl, although several muscles assist during the movement.our biceps muscle contracts both concentrically and eccentrically during the biceps curl. When you curl the weight up, the biceps muscle creates enough force to overcome the external resistance. During this phase of concentric contraction, the muscle fibers shorten, pulling at the elbow joint and lifting your forearm.
The bicep muscle is in the front of the upper arm; contracting it allows the elbow to bend and the upper arm to lift. The lower end of the muscle attaches to the bones of the forearm; at the upper end the muscle divides and is attached to two sites in front of the shoulder. Previous.
