Do you think maybe some of the motr powerfull boxers are like this because they are better at putting their weight into there punches?
naw...some guys are just hard hitters naturally...see tito..that dude hits hard and he weight a buck 05...see toney..fat as hell but cant drop a fly..
Some of it has to do with technique but most power guys are just born with it and the rest are not.
Other guys dont have as much power but they can still create power by throwing straight, sharp punches and having pinpoint accuracy.
