Stand in front of a mirror and station your head in relation to the space you have, so and so from this point and so on. Now change your perspective to your head in relation to your body as you move the body but keep the head imobile. Switch from one perspective to the next while you move and breath and repeat for other body parts. Now stand still and shake each part in turn and keep the motion only to the part you are shaking. If you are holding a knife level to punch between the ribs and shake the elbow than the knife will not show it. keep the forearm and hand dense as you shake your hips and consider how this prepares you to mass work and taking out the hits.
