I have a bad habit of punching from the torso, using my torso (obliques) to rotate my hips, rather than using my hips to rotate my torso!

So I have 2 problems, the 1st is I cant rotate my hips on their own, I dont have that control over them it feels natural instead to use my torso to turn my hips.

My second problem is I cant stop using my torso to turn my hips, I cant seem to "turn off" using my torso to rotate.

How do I keep my torso loose and unused so I can take advantage of the stretch reflex in it and get snap in my punches?

How do I gain control of my hips so I can rotate them at will by themselves without the torso?
