Take a normal boxing stance
Some people think that delivering the left hook requires a unique stance, which is absolutely wrong. You need to position your body normally, so that you are well balanced and in the position to attack your opponent. If you change your stance while delivering any move, the other person will pick that up easily and counter attack to pin you down.
Practice in front of a mirror
If you have not hired any trainer, you will be unable to find out the flaws in your boxing technique. So, the best thing to do in such a situation is to practice in front of a mirror, so that you can see what mistakes you make while delivering the left hook. Continue practicing this move for hours daily in order to master it. However, don’t try using it in a boxing ring unless you are sure it will work.
Keep one of your feet locked
Since you will have to gain momentum through a swing in your leg and torso, you will have to keep one of your feet positioned firmly onto the surface. It will provide support to the other leg and you will be able to swing the torso perfectly. Moreover, you will gain maximum momentum in your arm to deliver the left hook.
Transfer weight on the left side
As the name of this move suggests, you will have to transfer the weight of your body on the left side. This way, you will be able to gain maximum benefit from the left hook and your opponent will be unable to stand on his/her feet again.
