 Okay, so let me show you how to punch harder with less effort. The first tip is to have relaxation. So relaxation, if you end up pushing the target too much and you won't generate enough penetration power and impact into the target, if you lose enough you get to have more impact on the target. And you can hear it from the sound, if it's a push it's going to be a thud, if it's more relaxed it's going to be a smack. So you'll hear the sound a little different.
