The term "long head" often refers to a specific part of a muscle, particularly in anatomy. For example, the biceps brachii has two heads: the long head and the short head. The long head originates from the shoulder area and plays a crucial role in arm movements, such as lifting and pulling. In sports and fitness, understanding the long head is important for targeting specific muscle groups during workouts. Exercises like dumbbell curls can emphasize the long head, helping to build strength and size in the upper arm. Proper training can enhance overall performance and muscle balance.
