Karate has many basic moves that are classified as offensive or defensive. While there are many different styles of karate, basic moves, such as the forearm block and straight punch, are common to most forms.
One of the basic defensive techniques is the forearm block. This technique brings the forearm upward while holding it parallel to the ground. This makes it ideal for blocking punches to the face or a downward strike of any kind. At its full extension, the forearm is just over the forehead.
One of the most basic offensive moves is the straight punch. Unlike punches in boxing or mauy thai, which start from a higher position, this punch begins with the hand at hip-level. The other arm is fully extended with the hand in a closed-fist position. Force is generated by retracting the hand that is extended and extending the punching hand from the hip. As the hand is in the punching motion, it is rotated 180 degrees until the palm faces downward and is in the same position that the other hand was before the move was performed.
Karate is a form of self-defense that does not require weapons. Instead of weapons, this martial arts system takes advantage of the various parts of the body, particularly the arms and legs.
