Shield

Shielding, also known as the covering or blocking, is simply using your arm to absorb the blows delivered by your opponent. Shielding is best used against hooks, overhands, and wild punches.

To shield your head, slide your arm from the on guard position to the side of your head, making sure there there is NO space between your arm and your head. In other words, your arm should be resting on your head and the arm must be bent.
