A jab is a quick, straight punch thrown with the lead hand, commonly used in boxing and martial arts. It is typically aimed at an opponent's face or body to create distance, set up combinations, or disrupt their rhythm. The jab is known for its speed and versatility, making it an essential tool for both offense and defense. In addition to its use in boxing, the jab is also a fundamental technique in other combat sports like MMA and kickboxing. Proper technique involves rotating the shoulder and hip while extending the arm, allowing for maximum reach and power without compromising balance.
