The greatest stamina ever?? Marciano gets my vote.

Joe Frazier has to be mentioned. Incredible stamina . . Ray Robinson also had remarkable staying power and late-fight punching power . . .

then: 1-marciano 2-hagler 3-salvador sanchez now: 1-hopkins 2-morales 3-mab/winky Nothing wrong with that list, as far as I can see.

Marciano`s the man

Gotta go with Henry Armsrong.

I second the Hagler vote..

Not the greatest stamina but closer to today is when Pacman fought MAB, he did not stop and i thought he could have went on for 50 rounds easy

hagler comes to mind

Easily Marciano... Aaron Pryor and Salvador Sanchez are also excellent picks. Marciano used to run 5 miles a day, even when he was sick and even on X-mas day... THAT is determination. He never quit, no matter how tired or beaten he was. He was rewarded with the only undefeated record of any heavyweight champion in history.

Greatest stamina of all time? Easily the great Salvador Sanchez. Watch the 15th round of the Azumah Nelson fight. He had been in one of the toughest battles of his career, and wasn't even breathing hard! Its those mexican mountains that do the trick. I've trained in high elevations before, and that shit is crazy. When I lived in Suffern, NY, I used to train in the Catskills Mountains every morning. It's so hard to breathe up there, and its always cold, takes alot of determination.

All weight classes ... Remember the old time bareknuckle cats ... they went 50, 75, 100+ rounds sometimes ... Helluva lot of stamina :cool:

Henry Armstrong was a freak of nature. Salvador Sanchez NEVER got tired. His facial epression never changed.

Marciano was superhuman stamina wise, he just didn't stop... The old timers are even more impressive when you look back because they didn't have all these fancy diets or nutrition experts.

Is this greatest Hw stamina or all weight classes

Ike ibebuchi had great stamina

Aaron Pryor!!! that guy never stopped throwing punches. he would be all over his opponent all fight long. all of his ko's were from wearing out the other guy. he was truely a machine, he never stopped!!! the man had wells of stamina, and the most energy i've ever seen from a fighter.....if you don't beleive me watch like three of his fights. one from the beginning of his career, one in the middle, and one from the end. you'll see that his style never changed, it was an all out assault!!! good stuff too!!

The old school fighters definitely had it, and though you could say Marciano had the best stamina, frankly I'd be hard pressed to name any of the pre-60's champs who had poor stamina. They were all machines, who could go 15 rounds without slowing down, taking off a round, or getting weak in the legs. Don't ask me how they did it... ...training I guess.

I think Wlad Klitschko has the best stamina among boxers that are taller than 2 meters.

Wayne McCullough never been stopped or even knocked down, must have staying power to stay up right for so long!

Marciano is a great pick. Henry Armstrong deserves a mention. The man threw punches non-stop for 15 rounds, if it ever went that long. Man, that's a good choice too. He was a machine. How in the hell do those guys get into that kind of shape? People who can run 5 miles often could not last more than a few rounds.
