Re: Canelo Alvarez Power?
Some folks are just born with "heavy" hands and the ability to punch hard. Genetics plays a part, proper punching technique and training play a bigger part in my opinion. There's a lot of variables. Punching power generates at the floor up through the body.
Here's an example of 2 boxers on opposite ends of the spectrum. Take Paulie Mallignaggi with his feather fists and then Roberto Duran with his "Hands of Stone".
Both train/trained hard for their fights, one just possessed much superior power over the other.
