To build on this: hit soft things with hard things, and hit hard things with soft things. Fist to stomach, palm to face.

But palm is safest to yourself if you can’t control it.

Also, punch in a straight line. Hand goes from waist to face. Don’t make any detours. Hand doesn’t need to visit your shoulder or take a little tour out in space. Straight line to the target.

And of course, punch past the target. Through it. Hit the back of their head through the front. Kick their spine by way of their sternum. Etc.
