Gyaku-zuki, also known as the opposite punch, is a technique in martial arts that closely resembles the right or left cross used by boxers. Unlike the simpler oi-zuki, gyaku-zuki involves a more intricate structure. It necessitates a strong drive from the legs to generate momentum and precise direction from the waist to ensure the punch is delivered with maximum power. This technique is crucial for practitioners as it helps them develop a deeper understanding of power generation and the importance of maintaining correct body mechanics. Alongside gyaku-zuki, oi-zuki and kizami-zuki are considered the three fundamental linear delivery methods in martial arts. These techniques collectively contribute to mastering the art of delivering effective and powerful strikes.
