I've probably asked this question before, but I'll ask it again. Here is my question, and it concerns primarily throwing straight punches at an opponent, like 1-2 or 1-1-2. I was wondering if you should keep your head centerline when throwing straight punches, or move your head offline.

Like let's stick with the Jab-Cross. If you throw it with your head on the centerline, you throw a straight Jab with no hip rotation to the right and move in with a Cross, with which you do turn your hip to the left to increase the power of the shot.

If you throw off centerline, you throw a Jab and move your head to the right and twist your hip to the right to give the Jab power. Then you throw the Cross the same way I mentioned above.

Here is how I throw my Jab, with the twist of the hip, like the instructor does in the video. (Sorry for the shitty quality of the video)

Here is a more on centerline Jab-Cross

Is the way I do it right?
