About Hook Bruise
This is a more controlled and effective punch than a traditional haymaker punch because a hook punch is harder to block.
A hook punch is most effective at close range. If your opponent is far away from you, close up the distance between you and your opponent before executing a hook punch.
If you try to throw a hook too far from your opponent, they can block it, leaving you wide open for a punch to the face.
Practice your punches and know how close or far away from your opponent you need to be for your punches to be effective.
