Why do we yell in class?

• A. To scare opponents
• B. To satisfy instructors
• C. To obtain more power, regulate breathing, reduce tension, and show our confidence
• D. Because shouting is required for belt exams

Answer: (C)

Yelling in class, or kihap, is used to coordinate breath, body, and focus to improve performance. Exhaling forcefully at the moment of impact tightens the core and spine, increasing intra-abdominal pressure and helping your body drive through the technique with more power. The shout acts as a clear breathing cue, so you don’t hold your breath and you maintain a steady rhythm, which reduces unnecessary tension and keeps you relaxed enough to move quickly. It also communicates confidence and concentration, helping you stay mentally centered during the drill. While a shout can have a psychological effect, the main purpose in training is the combination of breath control, core engagement, and focused mindset that together boost power and precision.
