"Low guard" refers to a defensive stance in combat sports, such as boxing or martial arts, where a fighter keeps their hands positioned lower than the traditional guard. This position can allow for quicker strikes and more fluid movement, but it also exposes the fighter to potential attacks to the head and upper body. Fighters using a low guard often rely on head movement and footwork to evade incoming punches. While this technique can be effective for skilled practitioners, it requires a high level of awareness and reflexes to avoid getting hit, making it a more advanced strategy in competitive fighting.
