Which of the following is a common defensive technique in Taekwondo?

In Taekwondo, blocks are a fundamental defensive technique used to protect oneself against an opponent's attacks. They involve the use of the arms and hands to intercept or deflect strikes, thereby minimizing the impact of attacks. Understanding how to block effectively is crucial for maintaining an advantageous position during sparring or self-defense situations.

While counters, jumps, and drills are essential components of Taekwondo training, they serve different purposes. Counters refer to techniques used to respond to an opponent's attack, focusing on both defense and offense simultaneously. Jumps might be incorporated into techniques for agility or delivery of higher-impact strikes but are not exclusively defensive. Drills are repetitive practice routines that can improve skills and techniques but do not represent a specific defensive maneuver in themselves. Thus, blocks stand out as the primary defensive technique within the context of Taekwondo.
