 So you're thinking okay well that's pretty obvious, it's called rotation, right? But there's another type of rotational energy and that's with the rotation of your wrist. You see these in many martial arts where they tell you to use rotation of your wrist to generate more power but there's actually other kinds of rotation. So for example, when I'm doing this kind of rotation in my hands and then combine it with the rotation of my shoulders and my elbows then I can generate force because of rotation. If I didn't rotate, they'll be like this. But if I rotated, it's just a little bit more force. That's another way of adding rotational energy into your attack.
