👉 The fisting fluid, also known as the "fist pump" or "punching up," is a dynamic movement technique in boxing that involves rapidly alternating between heavy and light punches while maintaining a closed fist. This fluid motion engages multiple muscle groups, including the forearms, shoulders, and core, creating a powerful and efficient punching action. By keeping the fist closed during the heavy strikes, boxers can generate more force and maintain better control over their movements, reducing the risk of injury. The fluidity of the motion also allows for quicker transitions between punches, enhancing speed and agility on the cage. This technique is essential for maintaining a high punching rate and overall effectiveness in boxing.
