It is kinda funny if you think about it! Common sense would say if you move up in weight the more power you gain but it is not the case for boxers! their punching power diminishes.

Their power is the same, but now they're hitting larger men....who are accustomed to taking bigger punches.
Most of the time, also, a fighter is moving up & away from his best/most natural weight.

Nigel Benn said that he had to sacrifice speed to carry the muscle that got him to 168lbs, and said that when speed decreases power goes with it because, power = strength + speed. He said that he didn't get his power back until working with medicine balls with Kevin Sanders for the McClellan fight.

I think that may be corect cause when you move up your hitting larger men who can take your punch for example.

a middle weight is used to taking middle weight punches, so he obviously can take a welterweights punch when he moves up.


Can you name some fighters who maintained their one punch power when they moved up?

I can only name one right now and that is Thomas Hearns

Julian Jackson had some great KO's at 160, after having great KO's at 154. But, is 6lbs the kind of "big leap" we're talking about ?

Alexis Arguello had plenty of KO's from 126 all the way through 140.

Bob Fitzsimmons KO'd midles, lt. heavies, & heavies.


These guys were still big punchers as they rose in weight, but they didn't necessarily retain the same effectiveness from their original weight class.

they dont lose their power...they actually gain a tad more power. but these r bigger men, who r used to takin the big punches. so they might still get KO's, but their going to be taking biggger punches, n their going to be considered smaller

pacman had tons of power when he moved up seems he gained more power.

well Pacman is one of a kind, nyahahahahaha. And ya, good observation. Pac seems to carry his power even though he's been movin up in weight like crazy! he KOed bigga gays naturally like Barrera. That's why I have Pacman bein harder hitter than Rafael. Wehn Rafael moves up in weight and KO Pac or Barrera, then it means he is equal or ahead of Pac in terms of power.

Actually it doesn't mean Pac is necessarily a better puncher....it means he's a better FIGHTER.

I don't think Pac's power beat MAB, as much as his speed & tenacity did. Sure, he hurt MAB with his power, but those other two things were bigger factors.

Did Sanders teach him the sacred rabbit punching technique also?

Boxers gain power as they move up, but it is less effective against people who are normally bigger.

Miguel Cotto lokks like he could move up and keep power

Cotto does not haev one punch power.

If cotto moves up to 147 he is getting murderd and if he moves up to 154 he wont last. He is short and stubby.

I agree that he doesnt have 1 punch power. But the 147 pound division is easier than the 140

But zab judah will whoop cotto, and so would margarito.

they lose the speed...therefore the velocity on the punches isnt the same..but i really dont know if their loseing power...bigger fighters can take bigger punches

James Toney comes to mind first. he has maintained power moving up from middleweight to the fat ass heavyweight he is today.

Their power is the same, but now they're hitting larger men....who are accustomed to taking bigger punches.

That answers that question.

I think that may be corect cause when you move up your hitting larger men who can take your punch for example.

a middle weight is used to taking middle weight punches, so he obviously can take a welterweights punch when he moves up.

I can only name one right now and that is Thomas Hearns
Naseem Hamed.

when he moved up his power got so big it was unbelievable if you ask me.

He started as a bantam i believe and slowly worked through to featherweight.

Number 1 James Tone didn't gain more power or keep the power he had when he moved up to heavweight.All 3 of the so called heavyweights he fought were naturally cruiserweights and he only managed to stop a washed up Holyfield.
2nd All gaining weight doesn't increase your punching power.Gaining weight could make your physcially stronger but your punch will remain as it was at your lower weight.Holyfield was a big puncher at cruiserweight but once he moved up he didn't keep knocking out heavyweights besidse Tyson and Tyson has a glass chin.Roy Jones Jr,Tommy Hearns ect ect ect didn't have the same ability to knock out fighters as they moved up in weight.
That is why i try to tell morons about Marciano.Marciano was good at knocking out slow old bums who weighed 180 pounds so why just say if Marciano fought guys who weighed 50 pounds more than him that he could still bang with them and knock them out.I guess Marciano is different from most fighters to the fanboys of his.Logic only works for everybody else.

I think it just depends on the boxer. And also how weight is gained. If he's packing on muscle and going up in weight, punching power might increase significantly. Fat obviously won't do that.

And of course bigger guys are already used to getting hit by bigger punches. Then some guys are used to taking more punches than others. A bigger guy is usually less mobile than a smaller guy. So if a big guy is used to getting hit by big bombs, its going to take a lot more mini missles to put him down. Or maybe strategically placed missles (say to the body).

Trinidad had his best power at 154, IMO


He should have stayed there ,and reigned til now.
