Re: I thought punching power could not be improved at all!
I think you can gain power but only slightly. You're not gonna be some slap hitter one day then have thudding power the next. If a guy can already punch and he bulks up a bit his punching power will be roughly the same but there might be more momentum and impact. Muscles don't necessarily equal punching power either, I think Tim Bradley is more built for speed then power but if he suddenly let himself go and got a little chubby (whether that's even possible with his metabolism) I bet he would hit harder. Some of the strongest men on earth look like they have never worked out in their life.
